The present invention relates to an image display device having pixels including a light emitting element, and in particular, an image display device, an image processing device, an image display system, and an image display device control suitable for suppressing image display unevenness due to gradation display. The present invention relates to a program and an image processing device control program.

Conventionally, an electro-optical device, for example, a liquid crystal display device using a liquid crystal as an electro-optical material is widely used as a display device in place of a cathode ray tube (CRT) in a display unit of various information processing devices and a liquid crystal television. Here, in the conventional electro-optic device, for example, a pixel electrode arranged in a matrix, an element substrate provided with a switching element connected to the pixel electrode, and a counter electrode facing the pixel electrode are formed. It is composed of a facing substrate and a liquid crystal which is an electro-optical material filled between these two substrates. Then, in such a configuration, when a certain scanning line is selected, the switching element becomes conductive. In this conduction state, when an image signal having a voltage corresponding to the gradation is applied to the pixel electrodes via the data line, an electric charge corresponding to the voltage of the image signal is applied to the liquid crystal layer between the pixel electrode and the counter electrode. Is accumulated. Even if the switching element is turned off after the charge is accumulated, the charge accumulation in the liquid crystal layer is maintained by the capacitance of the liquid crystal layer itself, the accumulated capacity, and the like. In this way, when each switching element is driven and the amount of electric charge to be stored is controlled according to the gradation, the orientation state of the liquid crystal changes for each pixel. Therefore, since the density changes for each pixel, it is possible to display gradation.

At this time, since it is sufficient to accumulate the charge in the liquid crystal layer of each pixel for a part of the period, first, each scanning line is sequentially selected, and secondly, the pixel intersecting the selected scanning line is selected. By applying an image signal having a voltage corresponding to the gradation of the pixel to the corresponding data line, a time-division multiplex drive in which the scanning line and the data line are shared for a plurality of pixels becomes possible.

However, the image signal applied to the data line is a voltage corresponding to the gradation of the pixel, that is, an analog signal. For this reason, a D / A conversion circuit, an operational amplifier, and the like are required for the peripheral circuits of the electro-optical device, which causes a high cost of the entire device. Furthermore, due to the characteristics of these D / A conversion circuits and operational amplifiers, and the non-uniformity of various wiring resistors, display unevenness occurs, making high-quality display extremely difficult, especially with high definition. There is a problem that it becomes remarkable when displaying. There is also a problem such as an increase in power consumption due to a D / A conversion circuit or an operational amplifier.

Therefore, a method has been developed in which the light emission time of the electro-optical element is controlled to obtain gradation. In this method, it is sufficient to supply a binary signal (digital signal) as to whether or not the electro-optical element is made to emit light to the data line, and there is an advantage that the above-mentioned analog circuit which adversely affects the image quality becomes unnecessary. However, there is a problem that it takes too much time to select the scanning line in performing this control.

Therefore, a non-sequential scanning method has been developed as a driving method for a liquid crystal display using a digital signal to solve the above-mentioned problems. This is 2 of several bits of the bit string constituting the gradation data of bit length N indicating the emission gradation of the optical element.ⁿThe emission time of this optical element is controlled by selecting scanning lines non-sequentially using a numerical group corresponding to the ratio of values (n = 0,1,2, ··· (N-1)). This is a method of obtaining gradation (see, for example, Patent Document 1).<patcit num="1"><text>Japanese Unexamined Patent Publication No. 2001-166730.</text></patcit>

<p> However, although the principle of the non-sequential scanning method is described in theory, the specific method for actually embodying the non-sequential scanning method has not been clarified. Further, the selection order of the scanning lines is determined in advance in the memory of the control unit that controls each drive circuit of the electro-optical device according to the number of scanning lines to be controlled and the number of gradations. Although it is stored and controlled, an appropriate method for determining this selection order in the non-sequential scanning method has not been clarified.</p><p> Therefore, the present invention has been made by paying attention to the unsolved problems of such a conventional technique, and is suitable for displaying an image by using a scanning line selection process by a non-sequential scanning method. It is an object of the present invention to provide an image display device, an image processing device, an image display system, an image display device control program, and an image processing device control program.</p>

It is characterized in that the image display processing is performed by causing the scanning line driving circuit to select scanning lines in the scanning line selection order determined by the scanning line selection order determining means.</p><p> With such a configuration, the scanning line selection order determining means can determine the scanning line selection order corresponding to the bit string based on a preset irregular selection order. The selection order can be determined at high speed, and the image data can be displayed in the irregular selection order of the scanning lines. Therefore, it is possible to reduce the processing load and suppress display unevenness in high-definition image display and the like.</p><p> Here, when generating a numerical group as described above, if the total number of scanning lines + 1 cannot be divided by an accurate ratio (divided by an integer according to the ratio), the decimal point part in the part that cannot be accurately divided. By rounding, rounding, or selecting a value in the vicinity, it is possible to divide the value into the neighborhood values of the numerical values corresponding to each of the above ratios. For example, if the total number of scanning lines is 240 and the bit length of the gradation data is 6 bits, it will be divided at a ratio of 1: 2: 4: 8: 16: 32. In this case, Since there are parts that cannot be divided accurately, parts that cannot be divided into numerical values with an accurate ratio, such as 4, 7, 15, 30, 62, and 123, are defined as their neighborhood values.

For example, a selection order different from the previous one is selected for each frame to determine the selection order of the scanning lines, and each pixel of the image data is rearranged based on the determined selection order. It is possible to generate image data for non-sequential scanning. Therefore, the same selection order is not repeated in the entire display process, and image data in which the selection order is changed for each frame can be generated, so that display unevenness at the time of image display can be further suppressed for non-sequential scanning.

Here, the operation of the pixel circuit 3 in the present embodiment is controlled according to the writing of the bright signal supplied from the control unit 10b via the drive unit 10c as high or low, and the scanning line 30 When the bright signal is written as high via the data line 31, the optical element 35 is made to emit light, and when it is written as low, the optical element 35 is not made to emit light regardless of whether or not is driven. Further, in the present embodiment, the optical element 35 is an electroluminescence element. Further, the image display device 10 according to the present embodiment uses the signal (bright signal) applied to the data line 31 as binary bit data, and uses this bit data to make an optical element in a period of one frame. It is configured to control the light emission time of 35. As a result, the gradation display of the image is performed by controlling the light emission time of the optical element 35 according to the time corresponding to each bit of the bit string constituting the gradation data.

The control unit 10b controls the drive unit 10c according to the basic vertical scanning signal, horizontal scanning signal, dot clock signal, and gradation data. That is, the drive unit 10c is made to select the scanning lines in the image display area on the panel 10a in a non-sequential manner according to the selection order of the scanning lines determined by the image conversion unit 10f, and a voltage is applied to the pixels of the selected scanning lines ( Alternatively, it supplies an electric current).

The drive unit 10c is controlled by the control unit 10b, selects scanning lines in the image display area on the panel 10a in a non-sequential manner by non-sequential scanning, and is based on image data corresponding to the non-sequential selection order. A voltage is applied (or a current is supplied) to the pixels of the selected scanning line. The frame memory 10d is a memory for handling an image to be displayed in the image display area, and in the image display processing, the image data corresponding to the non-sequential scanning on the memory is taken out and the corresponding scanning line of the panel 10a is displayed. Drive the pixel.

The image analysis unit 10e analyzes the image data acquired from the external device and transmits the analysis result to the image conversion unit 10f. The analysis content here includes the number of colors and the resolution of the image data. The image conversion unit 10f converts the acquired image data into image data for non-sequential scanning based on the analysis result from the image analysis unit 10e and the number of scanning lines on the display panel. The converted image data is stored in the frame memory 10d. In the present embodiment, one of a plurality of types of irregular scanning lines stored in the selection order storage unit 10g is selected from the selection order, and the selected irregular selection order is used for the floor. The selection order of the scanning lines corresponding to the bit strings of the adjustment data is determined, and the conversion process of rearranging each pixel constituting the image data based on the determined selection order is performed to generate the image data for non-sequential scanning. .. Here, in the present embodiment, the irregular selection order is an order determined so that the scanning lines corresponding to each bit of the gradation data are in an order that is neither ascending nor descending in these bit positions. .. As for these selection orders, those determined in advance are stored in the selection order storage unit 10g.

The selection order storage unit 10g is used in advance in the image conversion unit 10f to determine the selection order of the scanning lines corresponding to the bit strings of the gradation data, which is used in the scanning line selection order determination process, in an irregular order. It stores a plurality of types of determined irregular selection orders. Here, in the present embodiment, although not shown, the image display device 10 is used for storing a storage medium for storing programs for controlling each of the above parts, a CPU for executing these programs, and executing the programs. It has a RAM to store the necessary data. Then, the processing of each part is realized by executing the program by the CPU.

The storage medium is a semiconductor storage medium such as RAM or ROM, a magnetic storage type storage medium such as FD or HD, an optical reading type storage medium such as CD, CDV, LD, or DVD, or a magnetic storage type such as MO. An optical reading type storage medium includes any storage medium that can be read by a computer regardless of the reading method such as electronic, magnetic, or optical.

Further, a more specific operation of the image display device 10 will be described with reference to FIGS. 1, 3 and 4. Here, FIG. 3 is a diagram showing an example of a plurality of types of selection orders stored in the selection order storage unit 10g, and FIG. 4 shows serial numbers (0 to 13) of scanning lines in the vertical direction and time in the horizontal direction. It is a figure which showed the appearance that the scanning line corresponding to each bit of the gradation data is selected in the selection order of the scanning line determined by a random number.

First, image data such as a moving image is transmitted from an external device such as a PC (Personal Computer) to the image analysis unit 10e. As a result, the image analysis unit 10e performs the image data analysis process. As described above, the analysis process examines the number of colors and the resolution of the input image. As a result, when information such as the number of colors and resolution of the image is known, the image conversion unit 10f inputs the information based on this information and information such as the total number of scanning lines of the panel 10a and the number of controllable emission gradations. Performs a process of converting the collected image data into image data for non-sequential scanning. Hereinafter, the image data conversion process will be specifically described.

Here, for convenience of explanation, a case where the total number of scanning lines is 14 and the bit length of the gradation data is 4 bits will be described as an example. First, 15 which is the total number of scanning lines 14 plus 1 is 2 which is the number of bits of the bit string constituting the gradation data of bit length N.ⁿGenerate a numerical group divided according to the ratio consisting of the values (n = 0,1,2, ···, (N-1)). That is, since the bit length N of the gradation data is 4 bits, it is 2⁰:2¹:2²:2³Divide the value 15 by adding 1 to the total number of scanning lines at a ratio of = 1: 2: 4: 8. In this case, it can be divided into 1: 2: 4: 8. Therefore, it is divided into four numerical values of 1, 2, 4, and 8 according to each ratio.

Next, a serial number from 0 to 13 is associated with each of the 14 scanning lines in total. Then, the serial number 0 of the scanning line (hereinafter referred to as the initial scanning line) to be selected first is set as the initial value in the LSB (0th bit) of the gradation data. Next, for the third bit (MSB) of the gradation data, the serial number 0 of the previously selected scanning line is added with the largest 8 of the divided numerical values, and this serial number 8 is used as the initial scanning line. Set as a serial number of. Further, for the second bit of the gradation data, the second largest 4 among the divided numerical values is added to the serial number 8 of the previously selected scanning line, and this 12 is used as the serial number of the initial scanning line. Set. Furthermore, for the first bit of the gradation data, the third largest 2 of the divided numerical values is added to the serial number 12 selected immediately before, but in this case, the added numerical value is the serial number. Since it exceeds 13, the remainder (0) when the addition result 14 is divided by the total number of scanning lines 14 is set as the serial number of the initial scanning lines. In the case of 15 which is the sum of 12 and 3, 15/14 = 1 (remainder 1), so the serial number of the initial scanning line in this case is 1.

Therefore, in the 4-bit bit length of the gradation data, the serial number 0 is set as the initial value for the LSB, the serial number 8 is set as the initial value for the MSB, and the serial number 12 is set for the second bit. It is set as the initial value, and the serial number 0 is set as the initial value for the first bit. In this way, according to the bit length of the gradation data, the divided numerical values are added in order from the largest to the smallest to the serial number of the previously selected scanning line as described above. The serial number of the initial scanning line corresponding to each bit of the gradation data is determined.

Further, any one of a plurality of types of selection orders stored in the selection order storage unit 10g is selected, and the selection order of the initial scanning lines is determined according to the selected selection order. In the present embodiment, as shown in FIG. 3, the selection order storage unit 10f stores four types of selection orders 1 to 4 corresponding to each bit of the gradation data. Here, the selection order 3 is selected from these four types.

In the present embodiment, the selection order of the initial scanning lines is determined by using the selection order of the selection order 3 as it is. That is, the selection order is: the initial scan line of serial number 8 corresponding to MSB the initial scan line of serial number 0 corresponding to LSB the initial scan line of serial number 12 corresponding to bit 2 the initial scan of serial number 0 corresponding to bit 1. Determine in the order of the lines. After that, 1 is added to the serial number of the initial scanning line corresponding to each bit, and the selection order is determined for the scanning line of the serial number of the addition result by using the calculation result of the random number in the same manner as described above. .. At this time, if the result of adding 1 to the initial value corresponding to each bit exceeds the value obtained by subtracting 1 from the total number of scanning lines (13 in this case), the addition result is set to 0. That is, when the 13th scanning line is selected and 1 is added to the serial number 13, the addition result is not set to a numerical value (14) exceeding the scanning line serial number 13 and is the minimum value of the scanning line serial number 0. And. Further, from the calculation result of the random number, the selection order of the scanning lines corresponding to each bit of the gradation data is determined by the order of MSB LSB 2nd bit 1st bit. Therefore, when the selection order is determined in the order of the 8th scanning line, the 0th scanning line, the 12th scanning line, and the 0th scanning line corresponding to each bit of the gradation data, thereafter. Add 1 to the serial number of the previously selected scan line corresponding to each bit, such as the 9th scan line, the 1st scan line, the 13th scan line, the order in which the 1st scan line is selected, and so on. The selection order is determined so that the scanning lines of the added serial numbers are sequentially selected.

In this way, when the selection order of the scanning lines corresponding to the total number of scanning lines is determined for each bit, the acquired image data is configured in the order according to the selection order based on the determined selection order. Image data is converted by rearranging the pixels to be used, and image data for non-sequential scanning is generated. Depending on the total number of scanning lines, the addition number obtained by adding 1 to the total number of scanning lines is 2 of the number of bits of the bit string constituting the N-bit gradation data.ⁿIt may not be possible to divide accurately according to the ratio consisting of the values (n = 0,1,2, ..., (N-1)). For example, consider a case where the total number of scanning lines is 240 and the bit length of the gradation data is 6 bits. In this case, the addition number 241 obtained by adding 1 to the number of scanning lines is divided by the ratio of 1: 2: 4: 8: 16: 32, but 241 cannot be accurately divided into this ratio. Therefore, if it is not possible to divide into numerical values with an accurate ratio, such as 4, 7, 15, 30, 62, 123, a numerical value group is generated by using the neighboring values.

The generated image data for non-sequential scanning is stored in the frame memory 10d. Then, as shown in FIG. 4, the images of the image data for non-sequential scanning stored in the frame memory 10d are subjected to non-sequential scanning lines in the selection order corresponding to the image data by the control unit 10b and the drive unit 10c. Is selected, and a voltage (or current) is applied to the corresponding pixel in the selected scanning line, so that the image is displayed in the display area on the panel 10a.

Further, the flow of operation processing of the image display device 10 will be described with reference to FIG. FIG. 5 is a flowchart showing the operation processing of the image display device 10. As shown in FIG. 5, first, the process proceeds to step S100, the image analysis unit 10e determines whether or not the image data has been acquired, and if it is determined that the image data has been acquired (Yes), the process proceeds to step S102. If not (No), wait until it is acquired.

When the process proceeds to step S102, the image analysis unit 10e analyzes the acquired image data and proceeds to step S104. Here, as described above, the number of colors and the resolution of the image are analyzed and examined. In step S104, the image analysis unit 10e transmits the analysis result to the image conversion unit 10f, and the process proceeds to step S106.

In step S106, the image conversion unit 10f determines the selection order of the scanning lines using the selection order stored in the selection order storage unit 10g, and steps in the order according to the selection order based on the determined selection order. The pixel data of the image data acquired in S100 is rearranged to generate image data for non-sequential scanning, and the process proceeds to step S108. In step S108, the image conversion unit 10f stores the converted image data in the frame memory 10d and shifts to step S110.

In step S110, the control unit 10b and the drive unit 10c perform a process of displaying the images of the image data stored in the frame memory 10d by non-sequential scanning in the selection order corresponding to the image data, and the process proceeds to step S100. To do. Here, the frame memory is prepared with two areas having a predetermined capacity, and the images are displayed by switching between these two areas. That is, while the converted image is stored in one area, the stored image is displayed in the other area.

Further, a flow of processing for determining the selection order of scanning lines in the image conversion unit 10f will be described with reference to FIG. FIG. 6 is a flowchart showing a process of determining the selection order of scanning lines in the image conversion unit 10f. As shown in FIG. 6, first, the process proceeds to step S200, the total number of scanning lines in the display area and the number of emission gradations of the display image are set, and the process proceeds to step S202.

In step S202, gradation data having a bit length N corresponding to the set number of gradations is generated, and the process proceeds to step S204. Here, when the number of gradations is determined from the beginning, it is not necessary to perform this process if the gradation data is generated in advance. Further, the gradation data is a variable having a bit length according to the number of input gradations. For example, 16 gradations is a variable having a bit length of 4 bits, and 64 gradations is a 6-bit bit. It is a variable with a length. In the present embodiment, there are 256 gradations of 8 bits.

In step S204, the number of additions obtained by adding 1 to the total number of scanning lines is 2 of the number of bits of gradation data having a bit length of N.ⁿA numerical group divided into numerical values corresponding to each ratio of the ratio group consisting of values (n = 0,1,2, ..., (N-1)) is generated, and the process proceeds to step S206. In step S206, the number of the initial scanning line corresponding to each bit of the gradation data is calculated and set based on the generated numerical value group, and the process proceeds to step S208.

In step S208, one of a plurality of types of selection orders stored in the selection order storage unit 10g is selected, the order in which the initial scanning lines are selected is determined according to this selection order, and the process proceeds to step S210. In step S210, the initial scan line is selected and the process proceeds to step S212. In step S212, 1 is added to each of the initial scan line numbers selected in step S210, and the process proceeds to step S214.

In step S214, it is determined whether or not the addition result of the numbers corresponding to each bit exceeds the total number of scanning lines, and if it is determined that there is an addition result (Yes), the process proceeds to step S216. If not, the process proceeds to step S222. When the process proceeds to step S216, the number of the addition result is updated to "0" and the process proceeds to step S218. That is, the serial number associated with the scanning line is updated to the minimum value (0 in the present embodiment).

In step S218, the scanning lines of the addition result numbers corresponding to each bit are selected, the selection order of the selected scanning lines is determined using the same calculation result as in step S208, and the process proceeds to step S220. In step S220, 1 is added to the number of the previously selected scanning line (the number selected in step S218), and the process proceeds to step S214.

On the other hand, when the addition result does not exceed the total number of scanning lines and the process proceeds to step S222, the addition result is set as it is and the process proceeds to step S218. In the image conversion unit 10f of the image display device 10, the selection order of all the scanning lines corresponding to each bit is determined by using one type of selection order selected from the selection order storage unit 10g. Not limited to this, every time 1 is added to the serial number to determine the serial number of the scanning line to be selected next, the selection order is selected from the selection order storage unit 10g, and the selection order of the scanning lines is selected using the selection order. May be decided.

Further, in the present embodiment, the image conversion unit 10f of the image display device 10 does not particularly specify the timing of selecting the selection order from the selection order storage unit 10g, but the selection of the selection order displays an image. It is possible to perform this every predetermined frame (for example, one frame). As a result, for example, one high-definition image is continuously selected for each frame in a predetermined order from the above four types or by randomly selecting one type and determining the selection order of the scanning lines. When displaying the time, a plurality of types of scanning line selection orders can be set, and it is possible to perform image display processing in a more irregular scanning line selection order when viewed from the entire display time.

Further, in the image conversion unit 10f of the image display device 10, one type is selected from a plurality of types of selection orders stored in the selection order storage unit 10g, and the scanning line is selected using the selected selection order. The order is determined, but not limited to this, one type of selection order determined in advance is stored in the selection order storage unit 21d, and the selection order of the scanning lines is determined using this one type of selection order. You can do it.

As described above, in the image conversion unit 10f, as described above, the selection order of the scanning lines in the non-sequential scanning is determined using the selection order selected from the selection order storage unit 10g, and the selection is made based on the determined selection order. It is possible to generate image data for non-sequential scanning by rearranging the pixel data of the image data in the order of arrangement according to the order. Further, the configuration of the image display system according to the present invention will be described with reference to FIG. 7. FIG. 7 is a block diagram showing a configuration of the image display system 2 according to the present invention.

As shown in FIG. 7, the image display system 2 includes an image display device 20 and an image processing device 21. The image display device 20 has a configuration including a panel 10a, a control unit 20a, a drive unit 10c, and a frame memory 20b. Here, since the panel 10a and the drive unit 10c are the same as those shown in FIG. 1, the description thereof will be omitted.

The control unit 20a controls the drive unit 10c based on the selection order information of the scanning lines stored in the predetermined area of the frame memory 20b and the image data for non-sequential scanning, and displays the image data image for non-sequential scanning. Do. The frame memory 20b stores the image data for non-sequential scanning and the selection order information of the scanning lines corresponding to the image data in a predetermined area on the memory from the image processing device 21.

The image processing device 21 has a configuration including an image analysis unit 21a, a device information acquisition unit 21b, an image conversion unit 21c, and a selection order storage unit 21d. The image analysis unit 21a analyzes the image data acquired from the external device and transmits the analysis result to the image conversion unit 21c. The analysis content here includes the number of colors and the resolution of the image data.

The device information acquisition unit 21b acquires information on the image display device 20 such as the number of scanning lines and the number of data lines in the display area on the panel 10a, as well as information on the number of emission gradations of the light emitting element. It is transmitted to the image conversion unit 21c. The image conversion unit 21c converts the acquired image data into image data for non-sequential scanning based on the analysis result from the image analysis unit 21a and the acquisition result of the device information acquisition unit 21b.

Similar to the image display device 10, one of a plurality of types of irregular scanning lines stored in the selection order storage unit 21d is selected, and the selected irregular selection order is used. The selection order of the scanning lines corresponding to the bit strings of the gradation data is determined, and the conversion process of rearranging each pixel constituting the image data based on the determined selection order is performed to obtain the image data for non-sequential scanning. Generate. Then, the image data for the selection order and the non-sequential scanning of the determined scanning lines is transmitted to the image display device 20.

Here, in the present embodiment, although not shown, the image processing device 21 is used for storing a storage medium for storing programs for controlling each of the above parts, a CPU for executing these programs, and executing the programs. It has a RAM to store the necessary data. Then, the processing of each part is realized by executing the program by the CPU.

The storage medium is a semiconductor storage medium such as RAM or ROM, a magnetic storage type storage medium such as FD or HD, an optical reading type storage medium such as CD, CDV, LD, or DVD, or a magnetic storage type such as MO. An optical reading type storage medium includes any storage medium that can be read by a computer regardless of the reading method such as electronic, magnetic, or optical.

Further, a more specific operation of the image display system 2 will be described. First, image data is transmitted from an external device such as a PC to the image analysis unit 21a of the image processing device 21. As a result, the image analysis unit 21a performs the image data analysis process. As described above, the analysis process examines the number of colors and the resolution of the input image. Here, in the present embodiment, the number of bits of the gradation data of the input image is 7 bits, and the total number of scanning lines of the image display device 20 is 127.

On the other hand, the device information acquisition unit 21b acquires information on the image display device 20 such as the number of scanning lines and the number of data lines in the display area on the panel 10a, as well as information on the number of emission gradations of the light emitting element, and obtains the acquisition result. It is transmitted to the image conversion unit 21c. When the analysis result of the image analysis unit 21a and the acquisition result of the device information acquisition unit 21b are acquired, the image conversion unit 21c performs a process of converting the input image data into image data for non-sequential scanning. Here, the process of generating image data for non-sequential scanning in the image conversion unit 21c is the same as the process of the image conversion unit 10f in the image display device 10, so the description thereof will be omitted.

When the image conversion unit 21c generates image data for non-sequential scanning, the image conversion unit 21c transmits the generated image data and the selection order information of the scanning lines corresponding thereto to the image display device 20. The image display device 20 stores the image data for non-sequential scanning and the selection order information of the scanning lines acquired from the image processing device 21 in a predetermined area of the frame memory 20b, respectively. The image display device 20 causes the drive unit 10c to display scanning lines in the order of selection of the scanning lines based on the image data for non-sequential scanning and the scanning line selection information stored in the frame memory 20b by the control unit 20a. The image display processing of the image data is performed by sequentially selecting the images and applying a voltage (or current) to the pixels corresponding to the selected scanning lines.

That is, the image display system 2 has a form in which the image analysis unit 10e, the image conversion unit 10f, and the selection order storage unit 10g of the image display device 10 are externally provided as the image processing device 21. However, unlike the above image display device 10, it is necessary to acquire information such as the total number of scanning lines and the number of emission gradations from the image display device 20, so it is necessary to add a device information acquisition unit 21b for acquiring such information. is there.

In the image display system 2, the total number of scanning lines is 127, so 128, which is obtained by adding 1 to this number, is 2 of the number of bits of the bit string constituting the 7-bit gradation data.ⁿIt will be divided according to the ratio consisting of the values (n = 0,1,2, ··· (7-1)). In other words, 128 is divided into a group of numbers according to the ratio of 1: 2: 4: 8: 16: 32: 64, and the numbers corresponding to each bit are 1, 2, 4, 8, 16, There are seven, 32 and 64.

Further, the flow of operation processing of the image processing device 21 will be described with reference to FIG. FIG. 8 is a flowchart showing the operation processing of the image processing device 21. As shown in FIG. 8, first, the process proceeds to step S300, the image analysis unit 21a determines whether or not the image data has been acquired, and if it is determined that the image data has been acquired (Yes), the process proceeds to step S302. If not (No), wait until it is acquired.

When the process proceeds to step S302, the image analysis unit 21a analyzes the acquired image data and proceeds to step S304. Here, as described above, the number of colors and the image size of the image are analyzed and examined. In step S304, the image analysis unit 21a transmits the analysis result to the image conversion unit 21c, and the process proceeds to step S306.

In step S306, the device information acquisition unit 21b detects the number of scanning lines (here, also the number of data lines) in the display area on the panel 10a, and proceeds to step S308. In step S308, the device information acquisition unit 21b transmits the detection result to the image conversion unit 21c, and the process proceeds to step S310. In step S310, the image conversion unit 21c determines the selection order of the scanning lines using the selection order stored in the selection order storage unit 21d, and steps in the order according to the selection order based on the determined selection order. The pixel data of the image data acquired by S100 is rearranged to generate image data for non-sequential scanning, and the process proceeds to step S312.

In step S312, the image conversion unit 21c transmits the selection order of the scanning lines determined in step S310 and the image data for non-sequential scanning to the frame memory 20b, and proceeds to step S300. In the image conversion unit 21c of the image processing device 21, the selection order of all the scanning lines corresponding to each bit is determined by using one type of selection order selected from the selection order storage unit 21d. Not limited to this, every time 1 is added to the serial number to determine the serial number of the scanning line to be selected next, the selection order is selected from the selection order storage unit 21d, and the selection order of the scanning lines is selected using the selection order. May be decided.

Further, in the present embodiment, the image conversion unit 21c of the image processing device 21 does not particularly specify the timing of selecting the selection order from the selection order storage unit 21d, but the selection of the selection order displays an image. It is possible to perform this every predetermined frame (for example, one frame). As a result, for example, one high-definition image is continuously selected for each frame in a predetermined order from the above four types or by randomly selecting one type and determining the selection order of the scanning lines. When displaying the time, a plurality of types of scanning line selection orders can be set, and it is possible to perform image display processing in a more irregular scanning line selection order when viewed from the entire display time.

Further, in the image conversion unit 21c of the image processing device 21, one type is selected from a plurality of types of selection orders stored in the selection order storage unit 21d, and the scanning line is selected using the selected selection order. The order is determined, but not limited to this, one type of selection order determined in advance is stored in the selection order storage unit 21d, and the selection order of the scanning lines is determined using this one type of selection order. You can do it.
