Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file device capable of recording various kinds of information such as image information in a file and recording the recorded file when necessary.

[0002]

2. Description of the Related Art Generally, a file device is indispensable as a device for storing, storing, and retrieving information in an information processing system. In this file device, for example, programs, numerical data, character data,
Record and hold image data. Further, the file device used in the information processing system is often connected to, for example, a computer device having a monitor device, and in this case, for example, in response to a user's search operation, information already filed is displayed on the monitor. It is displayed on the device.

Further, in the filing system including the file device and the monitor device as described above,
In order to enable high-speed access, the filing information is often recorded on a magnetic disk such as a so-called hard disk or a magneto-optical disk (MO disk).

[0004]

By the way, in a filing system including a file device and a monitor device as described above, when searching for filed information, what kind of filed information is used? A search image or a list of filed information may be displayed on the monitor device in order to inform the user whether or not the image is one.

At this time, since the display screen of the monitor device has a limited size and many file images cannot be displayed at the same time, it is often possible to reduce the above-mentioned search images and list display images to display them. The information is displayed. That is, the reduced list display for the search is performed, for example, as shown in FIG. 20, by reducing, for example, several pages of the filed image data and displaying them on the display screen. It should be noted that FIG. 20 shows an example in which reduced images each of which is a document for six pages from page 1 to page 6 are displayed.

However, in such a list display for a search, several pages are displayed in a limited display space. Therefore, for example, a reduced image of which characters can be read has a small number of list displays. Therefore, the efficiency of the search becomes poor. On the contrary, if the number of the list display is increased, the reduction rate must be increased, so that the content of the reduced image becomes difficult to understand.

In view of the above, the present invention allows the user to determine the content of each display image when performing a search or a list display, and further increases the number of display images to be displayed. It is an object of the present invention to provide a file device that can be used.

[0008]

The filing apparatus of the present invention has been proposed in order to achieve the above-mentioned object, and image information input means for inputting image information and information of a plurality of images are recorded. Recording medium, instruction input means for inputting a user's instruction, reproduction control means for reproducing and controlling information of an image recorded on the recording medium according to an arbitrary instruction of the user, and display for displaying an image. And a display unit having a screen, and when searching for a plurality of images recorded on the recording medium, a plurality of images are displayed on the display screen of the display unit in response to an instruction from the user. It is characterized in that only a part of which content can be recognized is displayed side by side.

The image displayed at the time of the search is a reduced image, and a part of the image is the upper part of the image.
The reduced image is generated by the reduced image information generation unit that generates reduced image information obtained by reducing the image of the image information input to the image information input unit, and the reduced image information and the input image information are combined. Are recorded together on a recording medium. Further, as the image information inputting means, one having an actual image information taking-in means for taking in a real image on a document and converting it into image information can be used. Furthermore, when displaying for the above-mentioned retrieval, only a part of the information of the image is read out from the recording medium is displayed, or only a part of each of the plurality of images read out from the recording medium is displayed. It is possible to superimpose each image so that the image remains so that it is displayed.

[0010]

According to the filing apparatus of the present invention, when a plurality of images recorded on the recording medium are searched, one of the plurality of images is displayed on the display screen of the display means in response to a user's instruction. By displaying only the parts side by side, more images can be displayed, and since some of these images are displayed so that the contents can be recognized, the user can know the contents of each image. become.

Further, by using a reduced image as the image displayed at the time of retrieval, it is possible to perform retrieval display corresponding to more images. Further, the upper part of the image often shows the content of the image remarkably, and by displaying this part, the content can be easily guessed.

Further, by generating the information of the reduced image obtained by reducing the input image in advance and recording it in the recording medium, it is possible to speed up the display of the reduced image. Furthermore, if the image information obtained by capturing the actual image on the document is used as the input image information, the actual image can be easily searched.

Further, when displaying for retrieval,
By displaying only a part of the information of the image read from the recording medium, the display for searching can be performed at high speed, and only a part of each of the plurality of images read from the recording medium can be displayed. If the images are displayed so as to overlap each other so as to remain, the searched images can be displayed at high speed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of an electronic filing device of this embodiment, which is a file device of the present invention.

In FIG. 1, the scanner 27 has, for example, a 200-dot / inch (dpi) CCD (charge-coupled device) line sensor and the like. For example, the size of paper of Japanese Industrial Standards (JIS) is used. Standard A row 4
By scanning a document of the largest size, the characters, symbols, numbers, figures, etc. written on the document are read, and the binary data, that is, image data is output. Further, when the object to be scanned by the scanner 27 is, for example, a photograph, the scanner 27 reads by a so-called dither method. By using this dither method, halftones are pseudo-expressed in black and white binary. In addition, the electronic filing apparatus according to the present embodiment is not limited to the scanner 27, and may be, for example, a CC.
A D camera (electronic still camera), a video camera, a video tape recorder, a video disc, or the like is used as the image information inputting means, or only an image input terminal to which image information from these is externally supplied is used as the image information inputting means. You can also

The data from the scanner 27 is sent through a buffer memory 26 and a bus to a memory 24 such as a RAM (tandem access memory) or a DSP (digital signal processor) 25 for compressing and expanding binary data. Sent to. For example, data including halftones, such as when the above-mentioned photograph is read by the so-called dither method, is not sent to the compression / expansion DSP 25 but directly stored in the memory 24.
To the compression / expansion DSP 25. In other words, if the binary data including the halftone is compressed, the deterioration of the image that is expanded and displayed later may become noticeable. The value data is not compressed by the compression / decompression DSP 25. The compression / expansion DSP 25 performs compression using a Huffman code of a variable length code as will be described later.

Writing / reading of the memory 24 is controlled by address data from a CPU (central processing unit) 20, and the data directly sent to the memory 24 is temporarily stored in the memory 24. Then, the data is read out, and further sent to the disk driver 31 via the bus and further via an interface section (not shown). In addition, the compression / decompression DSP 25
The data sent to is subjected to compression processing by the compression / expansion DSP 25, is sent again to the memory 24 via the bus, is temporarily stored therein, is then read from the memory 24, and is sent via the bus and the interface unit. Is sent to the disk driver 31. In the memory 24 used in the present embodiment, 1728 * 236 corresponding to the A column No. 4 above.
Data for eight pixels can be held. The CPU 20 also manages files, controls the flow of data, and controls the user interface, which will be described later.

The disk driver 31 writes data to a recording medium called a so-called Mini Disc (hereinafter, simply referred to as a disc in the present embodiment) which is a magneto-optical disc having a diameter of 64 mm. I am trying to record and play. Scanner 2 for the disc
By continuing the operation of recording the data obtained in step 7, it is possible to record, for example, several hundreds of document data on the disc. As the disc, a magneto-optical disc (MO disc) other than the above MD may be used, or a magnetic disc such as a hard disc may be used. However, a compact and inexpensive MD disc having a large recording capacity is used. Preference is given to using. The specific configuration of the disk driver 31 will be described later.

Next, the operation of reproducing a file in response to a user's request in the electronic filing apparatus of this embodiment shown in FIG. 1 will be described.

For example, when a reproduction request signal is supplied from the input unit 28 which is composed of a plurality of keys and a touch panel and controls the interface with the user, the CPU 20 records in the disc according to the reproduction request signal. To play the file that is being played. In addition to the keys and the touch panel, various input means such as a mouse or a pen input can be used as the device for generating the reproduction request signal.

As a result, the data of the file is read from the disk, and the data output from the disk driver 31 is sent to the memory 24 via the interface section (not shown) and further via the bus.
Here, when the data read from the disk is the compressed data, the data read from the memory 24 is sent to the compression / expansion DSP 25, and is compressed by the compression / expansion DSP 25. Corresponding decompression processing is performed to restore the binary data, and then the binary data is sent again to the memory 24.

The image data of the file read from the memory 24 is sent to the LCD (liquid crystal display) controller 22, converted into a video signal which can be displayed on the display 23 of the LCD by the LCD controller 22, and It is displayed on the display 23.

In the electronic filing apparatus of this embodiment, when it is desired to print the data read from the disc on, for example, paper, the data read from the disc and stored in the memory 24 is stored in the printer interface (I). / F) Send to the printer 30 via the circuit 29 for printing.

Further, in the disc driver 31, the signal from the disc is read by the optical pickup, and the rotation control of the spindle motor and the posture control of the optical pickup are controlled based on the signal, so that the disc on the disc. The laser light is made to follow the track at a constant speed. At this time, the disk driver 31 simultaneously controls the optical pickup including a laser diode and a photodetector and the magnetic field modulation coil that is the magnetic field generator, so that the compressed data or uncompressed data is recorded on the disk. Record binary data. In general, when recording on a magneto-optical disc, an optical modulation method that applies a DC signal to the magnetic field generator and a modulation signal to the optical pickup, and a control method that applies a modulation signal to the magnetic field generator and the optical pickup Although there is a magnetic field modulation system that gives a DC signal (makes the laser power constant), this embodiment employs the magnetic field modulation system. The modulation signal sent to the magnetic field generator is the above-mentioned compressed data or uncompressed binary data added with an error correction code, and further subjected to, for example, EFM (8-14 modulation). Therefore, when reproducing from the disc, EFM demodulation and error correction processing are performed.

More specifically, the disk driver 31 has a movable portion including a biaxial actuator, a spindle motor, a sled motor, etc.
The axial actuator is composed of a focusing coil that moves the objective lens of the optical pickup perpendicularly to the disc and a tracking coil that moves the objective lens in the radial direction of the disc. The optical pickup section of the disk driver 31 includes a laser diode which is a laser oscillator, a collimator lens,
It is composed of optical components such as an objective lens, a polarization beam splitter, and a cylindrical lens, and a photodetector which is a light receiving element having a light receiving portion of a predetermined pattern.
The laser light from the laser diode changes the temperature of the recording surface of the disk to the Curie point in order to see the magnetization direction of the disk during reading and for servo, and to record data on the disk by magnetic field modulation during recording. Used for raising above and for servo. The photodetector is used for detecting the tracking direction, focus servo, and the magnetization direction of the signal recorded on the disk by receiving the laser beam reflected from the disk. Further, the magnetic field modulation coil provided for performing the magnetic field modulation is applied to the EFM on a disc whose recording surface temperature is raised to the Curie point or higher by the laser light.
It is used for magnetic field modulation and recording of signals.

The hardware configuration of the electronic filing apparatus according to the present embodiment has been described above. Here, in the apparatus according to the present invention, in order to make it easy for the user, for example, a file stored in a disk is searched and the file is stored. When displaying, for example, the following is performed.

That is, in the apparatus of this embodiment, for example, file data such as a document is divided and stored, and the display screen of the display 23 is shown in FIG.
As shown in FIG. 3 and FIG. 3, a picture (what is called an icon) corresponding to the content of the file actually being filed is displayed. This allows the user to use the document as if it were stored in the picture of the file. In FIG. 2, the display screen 10 of the display 23 is displayed.
0, the holder icons 101 to 106 corresponding to the files displayed above and the instruction icon 11 described later.
0 to 115, and FIG. 3 shows the icon 120 of the headline title displayed on the display screen 100 and the display area 121 in which the reduced image is displayed.

Here, if a command is given from the input section 28 corresponding to these icons, for example, a file can be opened or closed. The icon may be a so-called computer graphic image, or may be an image in which features are extracted from actual image data. Further, a reduced image or the like is conceivable as the image from which the above feature extraction is performed.

The display of a list for searching by the icon and the display of the file based on the icon are described below in order.

First, the image of FIG. 2 is first displayed on the display screen 100 of the display 23 of the apparatus of this embodiment. Here, the icon of any one of the holders corresponding to each file displayed on the display screen 100 of FIG.
When an instruction is made with the pointing device according to, the instructed file is opened and becomes as shown in FIG. The instruction from the pointing device is displayed on the display screen 1
Icons 101 to 106 corresponding to the respective files on 00
In addition to the operation performed by instructing, the operation can be performed by instructing the pointing device instructing icons 110 to 116 corresponding to these icons 101 to 106, respectively.

Next, when the icon 120 indicating the heading title on the right side of the drawing is designated in the display as shown in FIG. 3, the first page of the heading is displayed as a reduced image, for example, in the left half. It is displayed in the area 121. Further, by pointing to the icon 122 corresponding to the page turning key displayed on the display screen 100 of FIG. 3, pages in this file are turned one after another and a search is performed. The page turning instruction can be made by pressing a page turning key actually provided on the input unit 28.

Next, when the page turning is instructed and a necessary screen is displayed on the display screen 100, the display area 121 of the reduced image is displayed by the pointing device.
On the display screen 100 of the display 23, an actual image corresponding to the reduced image displayed in the display area 121 is displayed on the display screen 100 of the display area 13 as shown in FIG.
Displayed at 0. This allows you to read the retrieved text in the file.

Here, as the reduced image displayed in the display area 121, a reduced image of the actual image data can be used each time the actual image data stored in the disk is called. However, in the case where the image data compressed as described above is recorded on the disc, in order to display the reduced image data in which the actual image is reduced, the compressed actual image Data is read from the disk, decompression processing is applied to this compressed real image data,
After that, the actual image data obtained by the decompression process must be subjected to reduction processing by a method such as thinning, and this reduced image must be displayed on the monitor. In addition to the complexity, it takes a long time to display a reduced image. For this reason, in the apparatus of this embodiment, in order to increase the display speed, the reduced image data is stored in the disk separately from the actual image data in advance as described later, and the reduced image data is read out first. So, I try to increase the display speed of the reduced image. That is, the apparatus of this embodiment has a structure in which a reduced image stored in advance on this disk is used for searching, and then an actual image is viewed. Details of recording the reduced image on the disk will be described later.

Further, in the file device of the present invention, in addition to the search by the headline title as described above, the file search by the list display is also possible.

In the file search by the list display, the icon 123 corresponding to the key of the list display is displayed on the display screen 100 shown in FIG. 3 after opening the file designated on the display screen 100 of FIG. 2 as described above. When a list display is instructed by giving an instruction, a list of the contents instructed by the icon 120 of the headline title is displayed.

Conventionally, when displaying such a list, only small screens as shown in FIG. 20 are aligned and displayed, but in the present invention, a reduced image of which characters can be read is displayed. As shown in FIG. 5, only the upper part of the page is left and displayed in an overlapping manner. That is, in the list display in the device of the present invention, as shown in FIG. 5, the size of the reduced image is set to a level such that the characters can be read, and these images are displayed as 1
A plurality of pages are overlapped and displayed so that only the upper part of the page (for example, about 1/4) is displayed.

Note that FIG. 5 shows an example of displaying a list of documents reduced in size, for example, 15 pages. As described above, the reason why only the upper part of the document is displayed is that the document which is frequently used at present is JI regarding the paper size.
Since the size of the A standard column No. 4 which is the S standard and the characters are written horizontally is overwhelmingly large, and the title of the document is shown on the upper part of the paper, so if this part can be read, the contents are guessed. This is because it was determined that it was possible. The user can call the real image data that has not been reduced by pointing the display unit, which is displayed only on the upper portion, with a pointing device, for example.

As described above, according to the apparatus of the present embodiment, it becomes possible to read a part of the characters and increase the number of the list display, so that the user can understand the contents of many documents at one time. It will be easier to search. It should be noted that each of the search images in which only the upper part is visible is linked to the actual image data. Further, in order to display more efficiently, only a necessary part (a part where a character is written) may be taken out and reduced and displayed.

Next, a management table for realizing the above is shown in FIG. That is, in the electronic filing apparatus of this embodiment, the above-described reduced image data for retrieval is created as file data as well as the actual image data of the document, and these are collectively managed.

[0040] In FIG 6, first, the data is divided for each file as the file management table TB _F,
The file management table TB _F is further divided into headings like a heading management table TB _I. The heading management table TB _I is managed for each page like the page management table TB _P , and the real image data TB _R and the reduced image data TB _s are managed for each page of the page management table TB _{P in} the one heading. Is managed. These data are updated every time an original document or the like in which a document or the like is written is read by the scanner 27, the reduced image data thereof is used at the time of retrieval, and the actual image data thereof is used at the time of reading the contents. The reduced image data is thinned out, for example, vertically and horizontally to 1/4 to 1/8, as will be described later. In the list display according to the embodiment of the present invention, the reduced image data is overlaid and displayed from the selected headline data as shown in FIG.

The apparatus of the embodiment of the present invention has software including the management table for improving the user interface as described above. In addition, the program data of the software, data for controlling each component, and the like are stored in a ROM (read only memory) 21.
Remembered in.

Therefore, the CPU 20 knows which data is displayed at which position on the display screen 100. Therefore, for example, if any one of them is selected in the search, the actual image data is located at any position in the disc. It is possible to find out whether it is recorded in the management table by the management table.

Next, the operation of the electronic filing apparatus of the above-described embodiment of the present invention will be described with reference to FIGS. 7 to 14.

After that, in step S72, it is determined whether or not another page list is to be displayed. If it is determined that another page list is to be displayed (Yes), the process returns to step S70, and if it is determined not to be displayed. The process ends for (No). It should be noted that, in the example of FIG. 13, the list display of the other pages is to display the upper part of the reduced image of, for example, pages 11 to 20.

Further, in the flowchart of FIG. 14 showing the document display processing of step S35 of the flowchart of FIG. 7, in step S80, the selected document data is read from the disc. In the next step S81, a document display icon is drawn on the display screen 100, and in step S82 the compressed document data is decompressed and displayed.

In the next step S83, it is determined whether or not the operation key is pressed. If it is determined that the operation key is not pressed (NO), in step S85, it is determined that the operation key is pressed. (Yes) proceeds to step S84. The operation keys are provided on the input unit 28, and are keys corresponding to respective operations such as reduction, enlargement, horizontal scrolling of display image, vertical scrolling, rotation, page turning, and printing.

In step S84, the display on the display screen 100 is operated, for example, by scrolling, rotating, or turning pages.

Next, in step S85, it is determined whether or not to return to the heading classification. If it is determined to return (yes), the process ends, and if it does not return, the processes of step S83 and subsequent steps are performed. .

Next, an example of generation of a reduced image in the apparatus of this embodiment will be described with reference to FIGS.

After the read signal is amplified by the amplifier 3, binary pixel data obtained by performing A / D (analog / digital) conversion and the like by the binarizer 4 is output. These line sensors 2
1, the amplifier 3, the binarizer 4, etc. are included in the scanner 27 of FIG.

The image data consisting of each pixel data expressed by the binary from the scanner is stored in the image memory 6 through the binary image data processing circuit 5 (details of this configuration and operation will be described later). To be done. The image memory 6 corresponds to, for example, the memory 24 shown in FIG. At this time, the binary image data processing circuit 5 sends the image data (each pixel data) serially supplied from the scanner to the image memory 6 as parallel image data of a predetermined unit, and the image data from the scanner. On the other hand, for example, while taking a majority decision, the thinned image data is generated, and the image memory 6 is parallelized in the same manner as above.
Send to. Hereinafter, the image data thinned while taking the majority decision to be sent to the image memory 6 is the reduced image data, and the image data from the scanner is the actual image data.

The image memory 6 is composed of an image memory 6a for an actual image that stores the actual image data and an image memory 6b for a reduced image that stores the reduced image data. In this case, separate image memories for the actual image and the reduced image are used as the image memory 6, but it is also possible to divide and use the storage area of one image memory corresponding to them. Is.

The actual image data read from the image memory 6a for the actual image is compressed by the compression processing circuit 7 and sent to the recording / reproducing block 8. The compression processing circuit 7 corresponds to the compression processing unit of the compression / expansion DSP 25 shown in FIG. On the other hand, the image memory 6 for the reduced image
The reduced image data read from b is directly sent to the recording / reproducing block 8. Recording / playback block 8
Is the actual image data compressed by the compression processing circuit 7 on the recordable and reproducible optical disc 9,
The reduced image data corresponding to the actual image data directly supplied from the image memory 6b is recorded as, for example, one file or another file. The recording / reproducing block 8 corresponds to the disk driver 31 shown in FIG.

As mentioned above, the optical disc 9 is called a magneto-optical disc having a diameter of 3.5 inches or a so-called mini disc which is a magneto-optical disc having a diameter of 64 mm. Things etc. can be used.

Here, the original 1 in the configuration of FIG.
The operation from the scan to the recording on the optical disk 8 will be described with reference to the flowchart of FIG.

In FIG. 16, when scanning of the original 1 is started by the scanner, in step S1, the image data from the scanner is stored in the image memory 6a as the actual image data, and at the same time, the reduction obtained by thinning out is performed. The image data is stored in the image memory 6b.

In step S2, the image memory 6 for the actual image
The actual image data read from a is compressed by the compression processing circuit 7, and the compressed actual image data is recorded on the optical disc 9 in step S3.

In step S4, the reduced image data read from the image memory 6b for reduced images is recorded on the optical disc 9. After that, the process returns to step S1.

As described above, in the example of FIG. 15, the original 1 is read by the scanner to obtain the image data, and at the same time, the reduced image data is also generated, and the reduced image data and the actual image data are recorded on the optical disc 9. I am trying.

Next, the data recorded as a file on the optical disc 9 as described above is reproduced based on the file search request from the user. Although not shown in FIG. 15, the file search request by the user is made from the input unit 28.

Here, in the electronic filing apparatus of the present embodiment, as described above, the compressed real image data is read from the disk, expanded, and then a reduced image obtained by thinning out is displayed on the display device. Instead, the reduced image data recorded on the optical disc 9 is read out and displayed on the display device 11 as it is.

As described above, after the reduced image is displayed on the display screen of the display device 11, the real image data (compressed real image data) of the file arbitrarily selected and instructed by the user from these displays is the above. It is read from the optical disc 9. The read compressed actual image data is sent to the decompression processing circuit 10, where after decompression processing corresponding to the compression processing in the compression processing circuit 7 is performed,
It is sent to the display device 11. As a result, the actual image of the file selected and instructed based on the reduced image display is displayed on the display screen of the display device 11.

The image displayed on the display device 11, that is, the reduced image corresponding to the reduced image data formed by the binary data processing circuit 5, is as shown in FIG. 17, for example. For example, the image data represented by the binary value captured by the scanner is
Assuming that the real image data corresponds to the real image as shown in FIG. 17A, the binary image data processing circuit 5 of the filing apparatus according to the present embodiment has, for example, FIG.
With the hardware configuration as shown in FIG. 17, reduced image data corresponding to the image as shown in FIG. 17B is generated at the same time as the actual image data.

The hardware configuration of the main part of the binary image data processing circuit 5 shown in FIG. 15 will be described below with reference to FIG. The configuration of FIG. 18 is a case where the data bus of the CPU 20 (not shown in FIG. 15) of FIG. 1 for controlling each component of FIG. 15 has 16 bits, and for example, a majority decision of 4 pixels in the horizontal direction is taken. However, the reduced image is generated by reducing the original image to 1/4 only in the horizontal direction.

In FIG. 18, the terminal 51 is connected to the terminal shown in FIG.
5, each serial pixel data is supplied from the binarizer 4, and a data clock (a pulse clock for each bit of pixel data) from a clock generator (not shown) is supplied to the terminal 52. The serial pixel data via the terminal 51 includes 16-stage shift register (16-bit shift register) SR1 and 4-stage shift register (4
Bit shift register) SR2 is sent to each register in the first stage. Further, the data clock via the terminal 52 has a clock input terminal of the shift registers SR1 and SR2 and a pulse number of the data clock of 1/16.
(That is, one pulse is formed for every 16 pulses of the data clock), and the number of pulses of the data clock is reduced to 1/4 (that is, once for every 4 pulses of the data clock). To form) 1/4
To the pulse generator 56.

In the shift register SR1, each pixel data from the terminal 51 is sequentially sent to the register of the next stage at every data clock from the terminal 52, and the pixel data is output from the register of each stage. That is, from the 16-bit shift register SR1, each pixel data accumulated in each register of 16 stages is output every data clock, and the 16-bit parallel image data is output via the terminal 66 to the real image. It is sent to the image memory 6a. At this time, the 1/16 pulse generator 55
From the terminal 52, a pulse is output once for every 16 pulses of the data clock, which is a terminal 61 as a real image data write pulse indicating the timing of writing the real image data to the image memory 6a for the real image.
Is output from. Therefore, the 16-bit real image data is stored in the image memory 6a for the real image only once every 16 clocks of the data clock.

On the other hand, also in the shift register SR2, in accordance with the data clock from the terminal 52, the terminal 5
Each pixel data from 1 is sequentially sent to the register of the next stage, and each pixel data is output from the register of each stage. That is, from the 4-bit shift register SR2, each pixel data accumulated in each register of four stages is output every data clock, and each pixel data is sent to the majority logic operation circuit 57. In this majority logic operation circuit 57,
The majority decision of the 4-bit data from the shift register SR2 is obtained by a logical operation, and the data resulting from the majority decision logical operation is sent to the first stage register of the 16-bit shift register SR3. In this example, since the majority logic operation is calculated from 4-bit binary data, when (0) and (1) are the same number (two each), any one of the predetermined values is determined. One of them (0 or 1) will be the majority logic operation result.

The shift register SR3 has a clock input terminal to which a pulse is supplied once every four pulses of the data clock from the quarter pulse generator 56. Therefore, the first stage of the shift register SR3. Pixel data from the majority logic operation circuit 57 accumulated in the register is thinned to 1/4. In the shift register SR3, the pixel data from the majority logic operation circuit 57 is decimated to ¼ for each pulse of the four pulses of the data clock supplied to the clock input terminal. Are sequentially sent to the register of the next stage, and each pixel data is output from the register of each stage. That is, from the 16-bit shift register SR3, the pixel data accumulated in each of the 16-stage registers is output every one pulse of every four pulses of the data clock, and the 16-bit parallel image data is output to the terminal. It is sent to the image memory 6b for the reduced image via 63. At this time, the 1/4 pulse generator 5
One pulse in every four pulses of the data clock from 6 further reduces the supplied pulse to 1/16 (that is, one pulse in every four pulses of the data clock is further reduced to 1/16). (Formed) to the 1/16 pulse generator 59, and the output of the 1/16 pulse generator 59 is a reduced image data write pulse indicating the timing of writing the reduced image data to the image memory 6b for the reduced image. It is output from the terminal 62. Therefore, in the image memory 6b for the reduced image, 16 times only once every 4 × 16 = 64 clocks of the data clock.
The reduced image data for bits will be stored. That is, the image to be formed by this reduced image data is a reduced image obtained by reducing the original image to 1/4.

Next, the operation of the configuration of FIG. 18 will be described with reference to the flowchart of FIG. In the flowchart of FIG. 19, in step S10, pixel data for each pixel is sent to the shift registers SR1 and SR2.

In step S11, the shift register SR
If the pixel data of 4 pixels is stored in 2, the majority decision logic operation circuit 57 takes the majority decision and sends the result of the majority decision to the shift register SR3.

In step S12, the shift register SR
If the pixel data for 16 pixels is stored in 1, the pixel data for 16 pixels (actual image data) is written in the image memory 6a for the actual image.

At step S13, the shift register SR
If the pixel data for 16 pixels is stored in 3, the pixel data for 16 pixels (reduced image data) is written in the image memory 6b for reduced images.

Finally, in step S14, for all pixel data obtained by scanning the document 1, step S14 is performed.
It is determined whether or not the processing from 10 to step S13 is completed. If it is determined that the processing is not completed, the procedure returns to step S10, and if it is determined that the processing is completed, the processing is terminated.

In the above example, the case of performing the horizontal reduction is described. However, when performing the vertical reduction, for example, one line is thinned out to four lines or the software is used. Make a majority vote in the vertical direction.

As described above, in the electronic filing apparatus shown in FIG. 15, a document such as a document is scanned and the actual image data of the scanner output is stored in the image memory 6a, and at the same time, a thinning process is performed while taking a majority decision. The reduced image data subjected to the above is generated and stored in the image memory 6b, the compressed actual image data is written to the optical disc 9 and the reduced image data is also written, and at the time of reproduction such as file search or list display. Since the reduced image data is read and displayed and the actual image data is read from the optical disk 9 only when the actual image is displayed, the search display and the reduced display of the list display can be performed at high speed. Further, in the filing apparatus of the embodiment of the present invention, the reduced image data is generated at the same time when the original 1 is scanned and recorded on the optical disc 9, so that the time required for the recording can be shortened.
