Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computerized information backup system used for back-up recording of computerized information including software information such as image data handled by a computer and its retrieval or processing program.

[0002]

2. Description of the Related Art Recently, in universities and research institutes, academic information such as research results is often created in an electronic form so that it can be handled by a computer. Most of this type of information includes high-definition image data and software information such as a search or processing program for this image data.

By the way, since this kind of information is generally valuable academically or technically, it may be caused by computer runaway, operator's erroneous operation, or disaster.
In order to prevent the information from being lost forever, the same information is recorded and stored in another recording medium. That is, information is backed up.

[0004]

However, in the conventional backup method, generally, electronic information to be backed up is stored and stored in an information recording medium such as a magnetic tape, a magnetic disk, or an optical disk. Therefore, if the information to be backed up contains high-definition image data or large-capacity software information as described above, a large-capacity and large-sized information recording is required to record these data. There has been a problem that a medium is required, resulting in an increase in cost and a large storage space. Further, in order to reduce the amount of stored information, image data is also compressed using a coding / decoding technique. However, once compressed image data cannot be completely restored, there is a risk of losing valuable information, which is not preferable.

The present invention has been made in view of the above circumstances, and an object thereof is to use a large-capacity and large-sized information recording medium for digitized information including image data and software information. It is an object of the present invention to provide an electronic information backup system capable of surely performing backup recording without any loss of information.

[0006]

In order to achieve the above object, the present invention comprises a display device and first and second display control means, and the image data in the backup target information is provided by the first display control means. Is displayed on the display device, and the software information in the backup target information is converted into bit pattern data by the second display control means and then displayed on the display device. An image pickup device is arranged opposite to the display screen of the display device, and the image data of the image data and the bit pattern data displayed on the display screen of the display device are respectively picked up by the image pickup device and exposed and recorded on a silver salt film. It is something that is done.

[0007]

As a result, according to the present invention, image data and software information are optically photographed and recorded on the silver salt film. For this reason, a large-capacity and large-sized information recording medium such as a magnetic disk or an optical disk is not required, and it becomes possible to save at a low cost and in a small storage space. Also, the resolution of the silver salt filter is extremely high, so by using a high-resolution display device,
Even high-definition image data can be recorded without lowering the resolution, and a large amount of software information can be recorded at a high density.

The film 4 is wound and unwound by a winder mechanism (not shown) having a motor. The winder mechanism is driven and controlled by the photographing control circuit 31 together with the shutter 34. Further, a magnetic recording head 37 is arranged at a position facing the film 4 in the film accommodating portion. The magnetic recording head 37 is for writing directory information and the like in a magnetic recording portion 42 formed on the film 4 described later, and is driven by the magnetic recording control circuit 32.

FIG. 2 shows an example of the structure of the film 4. A plurality of photographing regions 41, 41, ... Are formed on the strip-shaped silver salt color film base 40 at regular intervals. Further, on one side of the film base 40, the magnetic recording unit 4 is provided corresponding to each of the photographing regions 41, 41 ,.
2, 42, ... Are provided. These magnetic recording units 4
, 42, ... Are formed, for example, by applying a magnetic material to the film base 40. In addition, 43 is a sprocket.

As the computer 1, for example, a personal computer or a workstation is used. A ROM 11 and a RAM 12 are connected to the CPU 10 via a bus 17, and further an FDD interface (FDDI / F) 13 and an HDD interface (HDD
An I / F) 14, a display interface 15, and a camera interface 16 are connected to each. First, the FDD interface 13 exchanges data with the floppy disk driver (FDD) 5. The floppy disk driver 5 is used to read a backup recording program stored in a floppy disk (FD) (not shown). The HDD interface 14 exchanges data with the hard disk driver (HDD) 6. The hard disk driver 6
It is used to read out image data as backup target information stored in the hard disk and software information related thereto. Display interface 15
Transfers the display image signal to the display device 2. The camera interface 16 is the photographing control circuit 3 of the camera 3.
The control signal is transferred to 1 and the magnetic recording data from the magnetic recording control circuit 32 is fetched.

Next, the backup recording operation by the apparatus configured as described above will be described according to the control procedure of the CPU 10. Prior to recording, the operator sets the film 4 on the camera 3 and fixes the camera 3 at a position facing the display screen of the display device 2 with a fixture (not shown). Then, the floppy disk (FD) in which the backup recording program is stored is set in the floppy disk driver 5, the computer 1 is started, and the reading instruction of the floppy disk FD is input. Then, in the computer 1, the CPU 10 drives the floppy disk driver 5 in step 3a as shown in FIG. 3, whereby the backup recording program read from the floppy disk FD is stored in the RAM 12 via the FDD interface 13. .

Now, when the backup recording program is read into the RAM 12, the C of the computer 1 is read.
In the PU 10, backup recording control is started as follows according to this backup recording program. That is, as shown in FIG. 3, the hard disk driver 6 is first driven in step 3b. As a result, the backup target information recorded in the hard disk HD is read out, and the RA is transferred via the HDD interface 14.
It is stored in M12. At this time, the hard disk H
From D, the backup target information is read in units of one screen. Next, in step 3c, it is determined whether the read data is image data or software information such as a search / processing program.

As a result of this determination, it is assumed that the read data is image data. Then, this image data is directly transferred from the display interface 15 to the display device 2 in step 3d. Therefore, the transferred one screen of image data is displayed on the display screen of the display device 2. On the other hand, as a result of the above determination, it is assumed that the read data is software information. In this case, this software information is converted into bit pattern data in step 3i, and then transferred to the display device 2 from the display interface 15 in step 3j. Therefore,
On the display screen of the display device 2, the bit pattern for one screen of the software information is displayed.

When the data is displayed on the display device 2, the CPU 10 proceeds to step 3e. In step 3e, management information such as directory information read from the hard disk together with the image data or software information in step 3b is read from the RAM 12, and this management information is read from the camera interface 16 into the magnetic recording control circuit of the camera 3. 32. Therefore, in the camera 3, the magnetic recording head 37 is driven to write the management information in the magnetic recording portion 42 of the film 4. Next, the CPU 10 moves to step 33f. In this step 3f, the camera interface 16
A shooting control instruction is output to the shooting control circuit 31 of the camera 3 via. Then, in the camera 3, first, the shutter 34 is opened, and the bit pattern of the image data or software information displayed on the display screen of the display device 2 is exposed on the photographing area 41 of the film 4. Next, a winder mechanism (not shown) is driven to feed the film 4 for one frame. When it is confirmed in step 3g that the photographing for one frame has been completed, the CPU 10 determines in step 3 whether or not there is data that has not been read in the hard disk.
If it is determined in step h, and if data remains, the process returns to step 3b and the above series of control is repeated.

Thus, the image data of the backup target information and the software information are optically photographed and recorded on the film 4. Further, the management information associated with the image data and the software information is the magnetic recording portion 4 formed corresponding to each photographing area 41, 41, ... Of the film 4.
2, 42, ... Are written respectively.

As described above, in this embodiment, the computer 1 determines whether the read backup target information is image data or software information. If it is image data, it is as it is, or if it is software information. After being converted into bit pattern data, each is displayed on the display device 2. Then, in this state, the camera 3 is activated so that the image data or bit pattern data displayed on the display device 2 is photographed and recorded on the silver salt film 4. Further, the management information associated with the image data and the software information is written and recorded in the magnetic recording unit 42 provided on the film 4 by the magnetic recording head 37 of the camera 3.

Therefore, in this embodiment, since the silver salt film 4 is used as the recording medium, a large-capacity and large-sized information recording medium such as a magnetic disk or an optical disk is not required, which makes it possible to store at low cost and in a small amount. It becomes possible to save in space. Further, since the resolution of the silver salt filter 4 is extremely high, by using a high resolution display device, even high-definition image data can be recorded without lowering the resolution and a large capacity. The software information of can be recorded at high density.

For example, if the display device 2 having a 500.times.500 pixel CRT capable of displaying eight colors in each pixel is used, 250 kilobytes of information can be simply displayed. On the other hand, since the resolution of the silver salt film 4 is much higher than that of the CRT, it is possible to record with sufficient resolution even if the image data is of high definition. In addition, software information has an extremely large capacity, usually several hundred kilobytes to several megabytes. However, if the display device 2 and the silver salt film 4 are used, even if redundancy is provided for various errors,
Information of 100 to 200 kilobytes can be recorded in one frame of the silver salt film 4. Therefore, even a large amount of software information as described above can be recorded on the film 4 in a few frames to a dozen frames.

Further, in the present embodiment, as described above, the film 4 is provided with the magnetic recording portions 42, 42, ... Corresponding to the photographing areas 41, 41 ,. By recording in the magnetic recording portions 42, 42, ..., Retrieval of each frame in the film can be performed easily and quickly. (Second embodiment)

The management information recorded in the sections 42, 42, ... Is read. That is, all the frames of the film 4 are searched. Next, in step 5c, the frame in which the bit pattern data of the software information is recorded is searched based on the read management information of each frame. Then, the film 4 is stepwise conveyed by the conveying mechanism, whereby one of the frames in which the bit pattern data is recorded is set at the image reproducing position. Then, when the frame is set at the image reproduction position, an image pickup instruction is output to the television camera 8 in step 5d. Therefore, the television camera 8 takes an image of the frame in which the bit pattern data is recorded, and the image pickup signal is taken by the computer 9.
It is taken into the RAM 92. Then, when the reading of the image pickup signal for one frame is completed, it is determined in step 5e whether or not the reading from all the frames in which the bit pattern data is recorded is completed. If there are still unread frames, the process returns to step 5c and the above control is repeated.

Now, when all the bit pattern data has been read into the RAM 92, the CPU 90 thereafter carries out the search processing of the image data recorded on the film 4 in accordance with the search / processing protocol represented by this bit pattern data. Run. That is, first, step 5f
