[Detailed Description of the Invention]

[Objects of the Invention] (Field of the Invention) This invention relates to the information processor which processes picture information in the picture information memory retrieval device etc. with which picture information is memorized and searched, for example. (PRIOR ART) In recent years, image data, such as a document generated so much, is read with a scanner (two-dimensional scanning device), This read image data is registered into the optical disc, and the picture information memory retrieval device which searches desired image data out of this image data registered, and performs display or printing is put in practical use. In such a picture information memory retrieval device, management information, including image control information, search information (title information), etc., other than the image data read with the scanner is memorized by the optical disc as an optical memory measure. And the size of field Let's see these image data and management information on an optical disc are remembered to be is beforehand defined by the system concerned, and cannot be changed behind. therefore, the size of image data -- smallness (and -- if many pictures with much management information, including image control information, search information (title information), etc., are registered) In spite of having remained enough, management information area filled, picture registration beyond it of a drawing 1 elephant data area was not completed, but there was a fault that the storage area of an optical disc was effectively unutilizable. (Object of the Invention) If the size of image data registers many pictures with much management information small in the present invention as described above for example, In spite of remaining enough, management information area fills, and the picture data area cannot perform picture registration beyond it, but removes a fault that a storage area of an optical disc is effectively unutilizable. Therefore, it aims at providing an information processor which can utilize a storage area of an optical disc effectively without being influenced by size of size of image data, and amount of management information.

[Elements of the Invention] (Means for solving problem) An optical memory measure which has a memory information field where an information processor of this invention memorizes memory information, and a management information field which memorizes management information for managing the memory information, A memory measure which reads and memorizes the management information memorized by this optical memory measure, The 1st processing means that memorizes memory information to a memory information field of the optical memory measure with reference to management information read to this memory measure while updating, When management information memorized by the memory measure after memory of memory information by this 1st processing means is memorized to a management information field of the optical memory measure, When the management information field was full, a management information field was extended in a memory information field, and the 2nd processing means that memorizes the management information to this extended management information field was provided. (OPERATION) While referring to management information which this invention once read management information memorized by optical memory measure to a memory measure, and was read to this memory measure, With and a time of memorizing memory information to an optical memory measure, updating, and memory operation to a series of memory measures being completed, If a management information field which bundled up updated management information in a memory measure, and was provided into an optical memory measure when having re-memorized to an optical memory measure is full, a management information field will be extended in a memory information field, and management information will be memorized. Thereby, since a management information field became full in spite of having been vacant, the information storage field can avoid the situation where memory beyond it cannot be performed, and can be utilizing a storage area of an optical memory measure effectively.

While optical disk unit (optical memory measure) 22 memorizes image data read with scanner device 18 one by one to optical disc 20, Management information which consists of a memory address on optical disc 20 in which image data corresponding to search information inputted from keyboard 23 and this search information is memorized, picture size (picture length), a picture attribute, etc. is memorized. Image data corresponding to search information inputted by keyboard 23 is searched from optical disc 20.

While magnetic disk drive (memory measure) 27 memorizes various control programs to magnetic disk 26 with which this magnetic disk drive 27 was equipped, Management information which consists of a memory address on optical disc 20 in which image data corresponding to search information by which human power was carried out from keyboard 23, and this search information is memorized, picture size (picture length), a picture attribute, etc. is memorized. A documentation management system in account of picture information * Search device constituted as mentioned above changes on four hierarchies of a "cabinet", a "binder", "documents", and a "page", and a cabinet is matched with one side of point disk 20. A maximum of eight binders can be defined in a cabinet, and documents of a maximum of 30.000 affairs can be memorized in a binder. These documents have a title for every documents, and that title structure is defined per binder. The above-mentioned documents are the basic units of a file, and can add notes (explanatory note of documents) other than a title. Documents comprise a page of a maximum of 4095 pages. Image data which is in this documentation management system and is memorized by the above-mentioned optical disc 20 is managed on a documentation management table which is not illustrated. Drawing 2 shows a format of each area of optical disc 20 inside. "Format area" is a field which memorizes a block address and area size in an initial state of each area. 1 picture data area It is a field which memorizes image data read, for example with scanner device 18, and image data memorized here is image data compressed in the above-mentioned compression extension circuit 50." (memory information field) r image control information area It is a field which memorizes an attribute and a start address of each picture." (management information field) A field which memorizes an "area [ next ] block address" is established in 1 block of last of this image control information area. "Search information area" (management information field) is a field which memorizes search information on each picture, etc. 1 block of last of this search information area (a field which Remembrance straw matting "area [ next ] block address" eight times is provided.) Next, in such composition, operation of a picture information memory retrieval device is explained. First, an outline of operation of picture registration processing is explained. If optical disk unit 22 is loaded with optical disc 20 by operator, image control information and search information will be read, and it will begin to come out from management information area on point disk 20, and will memorize to a predetermined field of magnetic disk 26. Hereinafter, it will operate with reference to image control information and search information which were memorized by this magnetic disk 26, updating. In such A state Q!!, if it is in a selective state of a processing menu by CRT display device 24 and register mode is chosen by keyboard 23 now, CPU34 will display a title screen on CRT display device 23. Subsequently, an operator does human power of the title (search information) which should be given to the image data concerned using keyboard 23. This title comprises two or more items of a search key, and the contents of the item of this search key are set up as a title structure in the case of a binder definition performed beforehand. If there is an input of this title, CPU34 will check validity according to a format beforehand defined to an inputted title. Double registration is checked as compared with a title already registered into optical disc 20. A title inputted according to a result of this check is memorized by main memory 13, and is used in the following processings. Subsequently, picture registration processing is started according to the above-mentioned title. First, a manuscript is set in scanner device 18. CPU34 operates optical disk unit 22 and scanner device 18. Scanner device 18 scans image data, such as a set document, in two dimensions, and carries out photoelectric conversion. Line information on this drawing 1 elephant data by which photoelectric conversion was carried out is memorized one by one by page memory 40. Drawing memorized by this page memory 40 (elephant data is further memorized by display memory 42, and is displayed on CRT display device 24.) Skew of image data displayed on CRT display device 24 When it is what checks concentration, resolution, etc. and can satisfy displayed image data, human power of the storage key (not shown) is carried out. Then, CPU34 carries out coding processing by carrying out the bandwidth compression of the image data memorized by page memory 40 with MR method of common knowledge ,, etc. in compression extension circuit 50 for every line information. This image data by which coding processing was carried out is supplied to optical disk unit 22, and is memorized in a prescribed position of optical disc 20 according to image control information and search information which are memorized by magnetic disk 26. After memory of this image data is completed, CPU34 makes management information, including picture length, a picture attribute, etc., denoted by physical track address where image data was memorized, a logical address determined from a physical sector address, and block length correspond to a title, and it memorizes it to main memory 38. Subsequently, CPU34 outputs the above-mentioned management information memorized to main memory 38 to magnetic disk drive 27. Thereby, magnetic disk drive 27 memorizes management information supplied in magnetic disk 26, and ends registration processing. Management information is memorized by magnetic disk 27, while same operation is performed and image data is memorized by optical disc 20 one by one by setting the following manuscript in scanner device 18, when registering continuously. The above processing is repeatedly performed until registration processing of all the pictures is completed. Next, operation at the time of memorizing search information which is the feature of this invention and which is one of the management information to optical disc 20 is explained. In order to match image data and management information which are memorized in optical disc 20 and to maintain compatibility if a series of image data is memorized by optical disc 20 next, processing which re-records updated search information which is memorized by magnetic disk 26 on optical disc 20 is performed. That is, as shown in a flow chart of Drawing 3, offset from a head of area which should write in search information is read first. This offset is drawing (given from a program (not shown) which performs processing which writes elephant data in optical disc 20.). An applicable block address in optical disc 20 is computed from this given offset (Step Sl). Subsequently, it is investigated whether block area specified in a computed block address is full (Step S2). That is, it investigates whether applicable block area is full, except for "block address [ next ] area", if there is an empty field, it will branch to Step S8, and search information created on magnetic disk 26 is written in an applicable block. On the other hand, if there is no empty field that is, if search information area is used up, it will be investigated whether there is any extension of picture information area (Step S3). That is, since a block address of search information area (extended search area) which investigated 1 block of last of search information area, and was extended when the contents were not zero is shown, it branches to Step S9 and newly computes an applicable block from the block address. Subsequently, it returns to Step S2 and investigates whether a block secured as extended search area is full (Step S2), and the same operation is repeated until extended search area with an opening is found hereafter. If a block which has an opening in process of this repetition execution is found, with having described above, similarly, it will branch to Step S8 and will write search information created on magnetic disk 26 in an applicable block. On the other hand, since the next extended search area will not have been secured yet if the 1-block contents of last of search information area are zero, processing which secures extended search area is performed. That is, it is judged first whether the extended remaining area is in a picture data area (Step S4). This is performed by investigating the last block of a picture data area and investigating whether N blocks or more to extend as search information area remain. Here, "N" is a value arbitrarily decided by a system, and rlooJ is assigned, for example. In this case, an opening of 100 blocks or more remains in a picture data area, and it will be said that Extended search area is securable. Here, if it is judged that there is no extended remaining area in a picture data area, it judges that it is not memorizable any more to the optical disc 20, and it will branch to Step SIO, a message to that effect will be displayed on CRT display device 24, and picture registration processing will be ended. On the other hand, if it is judged that the extended remaining area is in a picture data area, it will secure as search information area (extended search area) which extends N blocks of them (Step S5). And a block address of a block secured to the last block of search information area before filling as extended search area is written in (Step S6). Subsequently, effective area of a picture data area is re-set up (Step S7). That is, from the last block address of a picture data area, a value which was secured as extended search area and which was reduced by N blocks is made into the new last block address, and is re-set up. Subsequently, with having described above, it progresses to Step S8, search information created on magnetic disk 26 is similarly, written in an applicable block of extended search area secured as extended search information area, and a series of processings are ended. Although the above-mentioned example explained a case where search information was memorized to optical disc 20, also when memorizing image control information to optical disc 20, it is completely carried out in the same operation. Next, search processing of image data memorized by optical disc 20 is explained briefly. For example, now, in a selective state of a processing menu by CRT display device 24, if search mode is chosen by keyboard 23, an operator will input search information corresponding to image data to search using keyboard 23. Subsequently, CPU34 searches a title table which is not illustrated. That is, it confirms whether search information which carries out comparison collation of the search information by which human power was carried out one by one with search information memorized in a title table in magnetic disk 26, and is in agreement with search information by which human power was carried out is memorized, and extracts an applicable filing number. And CPU34 displays a table of applicable documents using CRT display device 24. If documents which an operator wants to search are not found by this display, human power of search information is redone. If found, search execution will be directed by specifying the documents out of a table (it specifies with a display filing number etc.). CPU34 extracts all the pages which have an applicable filing number of a title table in magnetic disk 26, and record number information of those. And CPU34 reads a record number searched first and it reads a logical address corresponding to this record number from a title table in magnetic disk 26, A physical track address and a physical sector address corresponding to this address are computed, and image data memorized by optical disc 20 by these addresses is played with optical disk unit 22. Thus, image data reproduced with optical disk unit 22 is supplied to CPU34 for every scan line from optical disk unit 22. It A, and this image data (compression information) is supplied to compression extension circuit 50, and CPU34 performs zone extension processing, and supplies it to display memory 42 one by one. Thereby, image data memorized by display memory 42 is expressed as CRT display device 24. As described above, while referring to management information which once read management information memorized by optical disc 20 to magnetic disk 26, and was read to this magnetic disk 26, With and a time of memorizing image data to optical disc 20, updating, and memory operation to a series of optical discs 20 being completed, Updated management information in magnetic disk 26 is put in block, and it faces re-memorizing to optical disc 20, Since a management information field is extended in a picture day evening field and management information was memorized, when a management information field provided into point disk 20 was full, Since a management information field became full although 6n of image data region was vacant, it is the drawing beyond it (the situation where memory of elephant data cannot be performed can be avoided and a storage area of optical disc 20 can be utilized effectively.).

[Effect of the Invention] As explained in full detail above, according to this invention, the news processing unit which can utilize the storage area of an optical disc effectively can be provided, without being influenced by the size of the size of image data, and the amount of picture information.
