Description

[Detailed description of the invention] [Industrial application field] The present invention relates to image storage systems.

[Prior Art] Microfilm systems have conventionally been used as information storage devices that manage and utilize extremely large amounts of information. Microfilm is excellent in terms of economy, storage stability, resolution, etc., and has the advantages of fast input speed and the ability to make large quantities of copies at high speed. Are suitable.

However, microfilm systems have the drawback of not being compatible with computerized and communication-based office equipment.

On the other hand, since electronic file systems store information in the form of electrical signals, they have features that microfilm systems do not have, such as high-speed retrieval and high-speed transmission.

However, when inputting information in the electronic file system, it is not possible to convert the information in one shot through a lens system as in the case of a microfilm system, but instead performs raster scanning one by one to convert the information. For this reason, input speed is slow, human reader pull is not possible,
There are drawbacks such as the inability to make copies of a few hundred sheets or less at high speed and economically. In addition, compared to microfilm, which has a long-term storage stability of 100 years, there is not a sufficient track record of long-term storage stability (1
0 to 20 years), microfilm is not recognized as having legal evidence, and the database and information built using the microfilm system cannot be utilized. There is.

Therefore, electronic file systems and the like have been developed that photoelectrically read images on microfilms, that is, convert the read images into electrical signals and record the electrical signals on optical discs and the like.

However, in the electronic file system that has been developed, standard image information is recorded on a second recording medium,
When performing such a search, there is a problem in that the task of improving the search operation is not efficient, and as a result, the processing speed and operability are reduced.

[Object of the Invention] The present invention has been made in view of the above-mentioned circumstances. When standard image information is recorded on a second recording medium and the search is performed, the present invention efficiently improves the search operation. The purpose of the present invention is to provide an image storage system that allows for

[Embodiment of the Invention] Figure m1 is an external view of an image file system showing an embodiment of the present invention.

It also includes a document scanner 5 that converts document images into electrical signals, an optical disk device 6 that records image information on an optical disk, a host computer 7 that controls the entire system, a keyboard 8 that gives instructions to the host computer 7, and a keyboard 8 that provides instructions to the host computer 7. CRT9 that displays information on
is provided.

Furthermore, there is a signal line 10 that sends commands from the controller to the electronic microscanner 1, a signal line 11 that sends the image of the microfilm converted into an electrical signal to the host computer 7, and a signal line 11 that sends the image of the microfilm converted into an electric signal to the host computer 7, and a signal line 11 that sends the data between the scanner 5, printer 4, and host computer 7. Signal lines 12 and 13 for sending and receiving data are provided.

FIG. 2 is a block diagram showing the configuration of the above embodiment.

The CPU 50 is a Motorola microcomputer 6.
It consists of 8000 etc. The memory 51 temporarily stores image data and is also used as a work area for the CPU 50. An interface 52 for outputting data to the CRT 9 displays images read by a microfilm scanner or document scanner, operation instructions, etc. on the CRT 9.

Also, an interface 53 for receiving data from the keyboard, an interface 54 for transmitting and receiving data with the optical disk drive 6, an interface 55 for transmitting and receiving data with the reader 5, and a transmitting and receiving of data with the printer 4. An interface 56 is provided.

The interface 57, which exchanges data with the microscanner 1, converts serial image data sent from the microscanner 1 into 16-bit data in parallel. Bus 60 is a 16-bit wide bus through which image data and IJI# signals are transferred.

Next, the operation of the above embodiment will be explained.

FIG. 3 is a control flowchart showing the operation of the above embodiment.

First, the operator inputs search information for a desired file (or frame) from the keyboard 2 for the microfilm scanner (S l l), and then, according to the input search information, the film is fed and the desired file is retrieved. search for. When the desired file is retrieved, it stops at the reading position (512-1) and outputs a signal indicating that the desired film frame has been set to the host computer 7 (512-2). At this time, a desired frame is projected onto the screen 20.

Then, from the host computer 7 side to the interface 5
7, a reading size instruction signal, a resolution instruction signal,
It waits for a magnification instruction signal to be input (313-1).

The host computer 7 waits until a signal indicating that a film frame has been set is input (St
-1), and when you input that signal, the keyboard 8
In other words, it waits for the input of a command to read image data from the micro scanner l via the interface 57 (St-2).
).

When the command is input, the number of lines for sub-scanning and the number of dots for main scanning (l-line) are set in the control circuit in the host computer 7 according to the values of the reading size and resolution. , to the microscanner l, reading size, resolution.

A magnification command signal is output (S2-1).

That is, when storing a plurality of types of standard images in a predetermined storage means, type data (number of sub-scanning lines) indicating which of the standard images belongs to.

Image storage is controlled based on the number of dots in main scanning.

Next, the host computer 7 outputs a reading command signal to the micro scanner 1 (S2-2).

When the microscanner 1 receives the reading command, the microscanner 1 scans the image of the film frame with a CCD according to the commanded reading size, resolution, and magnification, and converts it into an electrical signal.

Output to the host computer side (S14).

The host computer 7 side stores the sent image data in the memory 51 (S3, 4).

Then, display the image data stored in the memory 51 on the CRT 9 (S5), and if there is an instruction from the keyboard 8 to record on the disk, output a frame advance command to read the next frame to the micro scanner 1 (S7). The image data is read from 51 and written to the optical disk (Sa).

When the micro scanner l receives a frame feed signal from the host computer 7 side, it feeds the next film, searches for the next frame, and sets it at the reading position (S 15 ,
16) Then, the above process is repeated until reading of one file is completed (S17).

Note that the film feeding operation for searching for the above-mentioned frame and the operation of recording the image of the previous frame on the optical disk on the host computer 7 side are performed in parallel.

When the recording of one frame is finished, it is determined whether or not all of one image file has been recorded (S9, 10). If not all have been recorded, the process returns to S1 again.

In the above example, the microfilm image is
Since the image can be displayed on the T, the operator can check the image before recording it on the disk. Further, in the above embodiment, the operator gives an instruction from the keyboard 8 to record one frame, but this can also be done automatically. That is, the determination process in S6 may be unconditionally determined as YES.

Further, in the embodiment described above, when the recording of one file is completed, the operator searches again for a new desired file, but it is also possible to record a plurality of files in succession.

Furthermore, in the embodiment described above, since the frame images of the microfilm are stored in the memory, even if an error occurs when recording onto the disk, the images can be read out from the memory and re-recorded.

Since there is usually no need to change the reading resolution and magnification during a batch of work, the command may be issued only once at the beginning, and then only the reading size may be commanded.

Furthermore, when instructing the reading size, the operator looks at the monitor screen 20 of the microscanner 1 and checks whether the image frame to be read is half-size (for example, A4) or full-size (for example, A3). ) to determine whether the photo was taken. Then, the reading size is instructed to the host computer 7 via the keyboard 2 of the micro scanner 1, and the host computer 7 sets the number of dots in main scanning and the number of lines in sub-scanning in an internal counter etc. according to the instruction. You may also do so.

Of course, all instructions such as reading size, resolution, magnification, etc. are performed using predetermined codes.

[Effects of the Invention] According to the present invention, when standard image information is recorded on the second recording medium and the search is performed, it is possible to efficiently improve the search operation.
