Hereinafter, the level adjusting device, the signal processing device, the AV processing device, and the program according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1A is a system configuration diagram of an AV processing system SY to which the AV processing apparatus of the present invention is applied. The AV processing system SY inputs to the AV processing device 30 and one or more CD players 10 (only one is shown in the figure) that generates one or more audio signals for input to the AV processing device 30. From one or more DVD players 20 (only one is shown in the figure) and one or more of these CD players 10 and / or one or more DVD players 20 that generate one or more video signals for Input one or more audio signals and / or one or more video signals (hereinafter referred to as "AV signals" to refer to audio signals and / or video signals) and edit them to obtain AV signals for output. It is composed of an AV processing device 30 to be generated, a speaker 40 that outputs an audio signal output from the AV processing device 30 as audio, and a monitor 50 that displays a video signal output from the AV processing device 30.

The AV processing device 30 of the present embodiment can input a plurality of AV signals, and the output levels of various elements related to these AV signals (for example, the volume in the case of an audio signal and the luminance rate in the case of a video signal). Perform various editing processes such as adjusting parameters). Further, as an example of the AV processing device 30, a DJ device (disc jockey) that is used in a club or the like and can handle audio signals and / or video signals as if it were an instrument, such as applying effects to both audio and video. A device that combines a DJ device used by (DJ) for acoustic performance and a VJ device used by visual jockey or video jockey (VJ) for video performance) and the like.

Here, VJ and DJ will be described. VJ improvises (synthesizes and connects) images to the music. While DJs improvise and mix music, VJs perform with video. Mainly at events and club parties, he performs performances that switch and output images on screens, etc., and is responsible for selecting appropriate images on the spot and playing them in a timely manner according to the progress of music and projects playing at the venue.

On the other hand, the DJ selects songs from the atmosphere of the place and plays them seamlessly. Perform live performances using a turntable that can change the pitch (speed) of the music. In addition to song selection, performances such as DJ mixes and scratches are common, and in mixes, the song currently being played and the song to be played next are smoothly connected, and the tension on the floor is eliminated by eliminating breaks in the sound. To maintain.

Currently, VJs and DJs are generally separated, and there are many people who usually perform for either music or video depending on their specialty. It is difficult to mix subjects other than specialized fields because each has its own specialty. Also, even if you only target one of them, you can improvise and apply more effects, so you need to perform various operations, which is very confusing. Therefore, there is no room to handle both.

However, in both cases, music and video are switched and output at a good tempo according to the atmosphere of the venue and the feeling of the performer himself. Since the sound and video provided must match, it is also desirable for one person to do both. Even if the VJ is originally good at video, if the music changes according to the change in the video, it will be easier to handle the music together with the video, and conversely, even a DJ who is originally dedicated to music will follow the change in sound. If the image changes, the sound and image can be handled more naturally.

The AV processing device 30 of the present embodiment provides simple and comfortable operation even when handling both music and video such as a DVJ device, so that video and music that cannot be handled by one person at the same time can be handled. It allows one person to handle at the same time.

The device for generating an AV signal to be input to the AV processing device 30 is not limited to the CD player 10 and the DVD player 20, but other devices (various audio devices, video devices, personal computers, etc.). You may. Further, the AV processing device 30 may have the functions of the CD player 10 and the DVD player 20 built-in. Further, the video signal may be a moving image or a still image.

FIG. 1B is a simplified configuration diagram of the AV processing device 30. The AV processing device 30 has a touch panel TP with a display function, a CPU 31, a GUI drawing unit 32, and a level control unit 33 as its main components.

The touch panel TP with a display function includes a display 41 having a display element such as a TFT and a touch panel 42 superposed on the display 41. By adopting the touch panel TP with a display function (hereinafter, simply referred to as "touch panel TP") in this way, the user can operate the touch panel 42 on the display of the display 41, so that the operation is simple and intuitive. It will be possible.

The CPU 31 performs position detection and movement detection of the operation position according to the voltage change (touch information) based on the operation (touch) of the touch panel TP. Further, based on the detection result, a display control signal for performing display control of the touch panel TP (display 41) and a level control signal for performing level adjustment are generated, and each signal is controlled by the GUI drawing unit 32 and the level. Output to unit 33. Further, the CPU 31 also performs integrated control of the AV processing device 30 such as information management based on the operation of various controls by the user and signal input / output with an external device.

The GUI drawing unit 32 performs GUI display on the touch panel TP based on the number of display control signals and AV signals input from the CPU 31. Further, the level control unit 33 is generally composed of an audio / video control device, controls the output level of the input signal based on the level control signal input from the CPU 31, and is based on the control result. Generate an audio signal for output and / or a video signal for output. Further, the level control unit 33 outputs these generated signals from the respective output interfaces.

Next, the user interface provided in the AV processing device 30 will be described with reference to the plan view of FIG. As shown in the figure, the AV processing device 30 includes the above-mentioned touch panel TP, a rotary controller (knob) 35, and an operation button 36 on the upper surface of the housing. As other user interfaces, the AV processing device 30 provides a confirmation display for the user to confirm the video of the video signal included in the output AV signal, switching of the input AV signal, and applying an effect effect to the input AV signal. It is equipped with various controls for this purpose (all not shown).

The touch panel TP displays operating members according to the number of input AV signals. The figure shows a display example when an AV signal is input only to CH1 and a linear fader F is used as an operating member.

As shown in the example of the figure, the fader F has an operator 61 and an orbit 62 which is a movement path of the operator 61, and the user moves the operator 61 along the orbit 62. This makes it possible to adjust the output level of CH1. Further, in the fader F, for example, when the operator 61 is located at the position PA (movement start position) and the position PB (arbitrary position) is specified (touched), the fader F is specified from the position PA to the position PB. The controls 61 can be moved at a constant speed over a (preset) travel time. That is, if it is a physically installed fader, the only way to operate the operator 61 is to move (drag) the operator 61 on the orbit 62, but the fader F is displayed by GUI as in the present embodiment. By realizing the above, the operator 61 can be operated by an operation of designating a "point" such as touching on the orbit 62. In addition, since the controller 61 moves from position PA to position PB at a constant speed, there is no variation in the movement speed, and smooth volume control that does not give a sense of discomfort to the audience, for example, when adjusting the volume of an audio signal. Can be realized.

On the other hand, the rotary controller 35 is for setting the movement time required for the operator 61 to move from the position PA to the position PB. In the present embodiment, by rotating the rotary controller 35, it can be set between 0 (seconds) and 120 (seconds). For example, when the movement time is set to 60 (seconds), the operator 61 slowly moves from the position PA to the position PB and reaches the position PB after 60 (seconds). The speed is constant at "distance from position PA to position PB / 60 (seconds)". In this way, when performing a slow fader operation, it is impossible to actually operate the operator 61 with a human finger to move it at a constant speed, but according to the present embodiment, such an operation is also possible. It can be done easily.

The amount of change accompanying the rotation of the rotary controller 35 does not increase or decrease linearly (increases or decreases at a constant rate regardless of the position of the rotary controller 35), but increases linearly at 2 o'clock (rotary type). The rate of change increases as the controller 35 approaches the maximum value). According to this configuration, it is easy to make detailed settings in a range where the travel time is short (near the minimum value).

The operation button 36 is an operation mode setting button for setting one of three operation modes having different operations when the designation of the operator 61 is released (when the finger is released from the touch panel TP). In the present embodiment, when the first operation mode is set, the operation element 61 is returned to the movement start position when the designation of the operation element 61 of the fader F is released. Further, when the second operation mode is set, when the designation of the operation element 61 of the fader F is released, the operation element 61 is returned to the predetermined return position. Further, when the third operation mode is set, when the designation of the operation element 61 of the fader F is released, the operation element 61 is stagnant at the specified position (arbitrary position). The details of each operation mode will be described in detail later with an example.

The movement time required and the operation mode can be set not only by the above-mentioned rotary controller and operation buttons, but also by using other controls such as a cross key and a joystick.

Next, the control configuration of the AV processing device 30 will be described with reference to the block diagram of FIG. As shown in the figure, the AV processing device 30 includes an input means 310, an operation means 320, a display means 330, a movement time required setting means 340, an operation mode setting means 350, a display control means 360, a level control means 370, and an output means. It has a 380.

The input means 310 inputs a plurality of AV signals (input AV signals), and its main part is composed of a signal input interface (USB, MIDI, etc.) (not shown). The main part of the operation means 320 and the display means 330 is composed of the touch panel TP. The operation means 320 adjusts the output level of the signal corresponding to the operation member by the user operating the operator 61 of the operation member (fader F) displayed on the touch panel TP. Further, the display means 330 displays the operation member in GUI.

The movement time required setting means 340 is an arbitrary position designated from the movement start position which is the position of the controller 61 before the designation when an arbitrary position on the trajectory 62 of the operation member is designated by the operation means 320 as a point. The movement time required for moving the operator 61 to the position of is set, and the main part thereof is configured by the above-mentioned rotary controller 35 (see FIG. 2). Further, the operation mode setting means 350 sets the operation of the operator 61 when the designation of the operator 61 is released by the operation means 320, and the operation mode setting button 36 (see FIG. 2) described above sets the operation of the operator 61. The main part is composed.

The display control means 360 controls the display of the display means 330 based on the operation of the operation means 320, such as reflecting the operation result of the operation means 320 on the display means 330. (See Fig. 1 (b)) constitutes the main part. When the operator 61 is dragged along the trajectory 62, the display control means 360 moves the operator 61 according to its manual speed. Further, when an arbitrary position on the orbit 62 is specified by a point, the operator 61 is moved to the arbitrary position at a constant speed over the movement required time set by the movement required time setting means 340. ..

Further, the display control means 360 performs display control when the designation of the operator 61 is released based on the setting of the operation mode setting means 350. In particular, when it is set to the first operation mode (when the operation element 61 is set to return to the movement start position when the designation of the operator 61 is released) or when it is set to the second operation mode (when it is set to the second operation mode ( When the designation of the operator 61 is released, the operator 61 is set to return to the predetermined return position), the movement is moved from an arbitrary position over the movement time set by the movement time setting means 340. Move the operator 61 at a constant speed to the start position or return position.

The level control means 370 controls the output level of the signal corresponding to the operation member based on the position of the operator 61 of the operation member displayed on the display means 330 in accordance with the display control of the display control means 360. Yes, the main part is composed of the above CPU 31 and level control unit 33 (see Fig. 1 (b)). Further, the output means 380 outputs an AV signal (output AV signal) based on the output level controlled by the level control means 370, and uses a signal output interface (USB, MIDI, etc.) (not shown) to output the AV signal (output AV signal). The main part is composed.

Next, with reference to FIG. 4, display control when an arbitrary position of the operating member (fader F) on the trajectory 62 is designated by a point will be described. Here, it is assumed that the first operation mode (a mode in which the operator 61 is returned to the movement start position when the designation of the operator 61 is released) is set.

As shown in Fig. (A), when the movement time is set to t (seconds) (however, t&gt; 0 (seconds)), from the state where the operator 61 is located at the movement start position PA. , When an arbitrary position PB is specified (when touched by the user), the operator 61 moves at a constant speed from the movement start position PA to the arbitrary position PB over time t (seconds). Further, when the designation of the operator 61 is released from the state where the operator 61 is located at the arbitrary position PB, the operator 61 takes the same time t (seconds) to move from the arbitrary position PB to the start position. Return to PA at a constant speed.

In addition, as shown in Fig. (B), when the movement time is set to 0 (seconds), any position PB is specified from the state where the operator 61 is located at the movement start position PA. Then, the operator 61 teleports from the movement start position PA to an arbitrary position PB. Further, when the designation of the operator 61 is released from the state where the operator 61 is located at the arbitrary position PB, the operator 61 instantly returns from the arbitrary position PB to the movement start position PA.

In this way, the user can move the operator 61 over a desired time or instantly by designating an arbitrary position on the orbit 62 of the fader F as a point. Further, by releasing the designation, the operator 61 can be returned to the operation start position over a desired time or instantly.

Next, each operation mode will be described with reference to FIG. The figure shows the case where the movement is released after moving from the movement start position PA to an arbitrary position PB specified by a point. In addition, it is assumed that the travel time is set to t (seconds). As shown in FIG. 6A, when the first operation mode is set, the operator 61 returns to the movement start position PA when the user releases the designation. As described above, it takes t (seconds) to move from the arbitrary position PB to the movement start position PA at this time.

Further, as shown in FIG. 6B, when the second operation mode is set, the operator 61 returns to the predetermined return position PC when the user releases the designation. Even at this time, it takes t (seconds) to move from the arbitrary position PB to the return position PC. Therefore, the movement speed is different between the return when the first operation mode is set and the return when the second operation mode is set (in the case of the example in the figure, the second operation mode is set. If you have it, the movement speed will be faster). The return position PC may be set in advance, or may be set by the user by a predetermined operation.

On the other hand, as shown in FIG. 3C, when the third operation mode is set, the operator 61 remains stagnant at the predetermined position PB even if the user releases the designation. Therefore, when the third operation mode is set, the setting of the travel time is not affected.

In this way, the user can set the operation mode according to his / her preference. The operation mode may not be fixedly set by the operation of the operation mode setting button 36, but the operation mode may be switched by an arbitrary position designation method or the like. For example, if an arbitrary position is specified by a single click, the operator 61 returns to the movement start position according to the first operation mode, and if an arbitrary position is specified by a double click, the third operation mode is set. Therefore, the operator 61 may be configured to be stagnant at an arbitrary position.

Further, the operation mode may be applied not only when an arbitrary position on the trajectory 62 of the fader F is specified by a point, but also when the operator 61 is manually moved. That is, after the user drags the operator 61, when the finger is released from the touch panel TP, the operation may be performed according to each operation mode. In addition, the user's preference is whether to apply the operation mode only when an arbitrary position is specified by a point, to apply the operation mode only when the operator 61 is manually operated, or to apply both. It may be possible to set according to.

As described above, according to the present embodiment, since the operation member is operated by using the touch panel TP, the output level can be adjusted easily and intuitively. In addition, by designating an arbitrary position on the orbit of the operating member with a point, a predetermined movement time can be set from the movement start position, which is the position of the operator 61 before the designation, to the designated arbitrary position. Since the operator is moved at a constant speed, the moving speed does not vary, and the output level can be adjusted, which cannot be achieved by the mechanical operating member. Further, the movement required time can be set according to the user's preference and needs. For example, when the movement required time is set to 0, the operator 61 can be moved instantly. Further, if the movement time is set to a long time such as 60 (seconds), it is possible to realize a low-speed constant-speed movement that cannot be realized by a mechanical operating member. As described above, the AV processing device 30 in the present embodiment can realize an original adjustment of the output level, and is effective for various video expressions and musical expressions.

In the above embodiment, the case where only one operating member (fader F) is displayed on the touch panel TP is illustrated (see FIG. 2), but the number of operating members corresponding to the number of input signals is displayed on the touch panel TP. It may be displayed in. FIG. 6A shows a display example of the touch panel TP when three signals CH1 to CH3 are input. In this way, when three signals CH1 to CH3 are input, the three faders F1 to F3 corresponding to each signal are displayed, and the corresponding channels are displayed (CH1 to CH3) 71. Display ~ 73. According to this configuration, since the number of operating members corresponding to the number of input signals is displayed, unnecessary operating members are not displayed even in the AV processing device 30 capable of inputting a large number of signals. , Does not impair operability.

It should be noted that not only the number of operating members corresponding to the number of input signals is displayed on the touch panel TP, but also the operating members are arranged on the touch panel TP so as to be appropriately arranged according to the number of input signals. It is preferable to arrange it. Further, in this case, it is preferable to arrange each operating member in consideration of operability according to the type of signal and the parameter for adjusting the output level.

Further, in the above embodiment, the linear fader F is displayed as the operating member, but the rotary fader FR may be used. FIG. 6B shows a display example of the rotary fader FR. In the case of the rotary fader FR, the operator is the knob 80, but the "position of the operator" corresponds to the position of the reference mark 81 provided on the knob 80. Further, in the case of the rotary fader FR, the orbit 82 has a circular shape (in the illustrated example, a part of the inoperable region is formed).

In addition to the linear fader F and rotary fader FR described above, operating members of various shapes can be used as long as the output level can be adjusted by moving the controller along a predetermined trajectory. (Controller) is applicable.

Further, in the above embodiment, for example, in the case of the first setting mode, the movement starts from the movement start position to an arbitrary position in the set movement required time, and returns from the arbitrary position to the movement start position in the same movement required time. However, it may be possible to set different travel time required for the outward trip and the return trip to an arbitrary position (individual travel time required setting means). According to this configuration, the operator 61 can be moved from the movement start position to an arbitrary position and from the arbitrary position to the movement start position at the movement required time desired by the user. Also in the second setting mode, different movement required times can be set for the outward route (from the movement start position to the arbitrary position) and the return route (from the arbitrary position to the return position) to the arbitrary position.

Further, in the above embodiment, the time required for movement can be set, but instead of this, the movement speed when the operator 61 moves from the movement start position to an arbitrary position may be set. .. According to this configuration, since the moving speed of the operator 61 can be directly specified, the user can easily assume a change in the output value. It should be noted that different movement speeds may be set for the outbound and inbound movements to arbitrary positions in the first setting mode and the second setting mode.

Further, as the AV processing device 30, a DVJ device used in a club or the like is illustrated, but in addition to the DVJ device, a device or program (audio / video mixer, audio / video mixer, etc.) capable of inputting a plurality of AV signals and editing them. The present invention can be applied to any audio / video controller, audio / video processing application, etc.). That is, the present invention can be applied not only to a device that processes both an audio signal and a video signal, but also to a device that processes only an audio signal and only a video signal.

It is also possible to provide each part and each function of the AV processing apparatus 30 shown in the above example as a program. It is also possible to store the program in a recording medium (not shown) and provide it. As the recording medium, CD-ROM, flash ROM, memory card (compact flash (registered trademark), smart media, memory stick, etc.), compact disk, magneto-optical disk, digital versatile disk, flexible disk, hard disk, etc. can be used. it can.

Further, regardless of the above-described embodiment, the system configuration of the AV processing system SY, the device configuration of the AV processing device 30, the processing process, and the like can be appropriately changed without departing from the gist of the present invention. For example, the input signal is not limited to an audio signal or a video signal, but may be another signal, and a level adjusting device in which the input means 310 and the output means 380 are omitted from the AV processing device 30 is also the present invention. It is the scope of rights.
