Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an image processing device.

[Prior Art] A negative (or positive) microfilm F as shown in FIG. 5 is used in a conventional information retrieval device.

The film F is provided with a large number of information frames in which predetermined information is photographed and recorded at regular intervals.

One frame mark m is attached corresponding to one information frame.

Also, let Al-A4 be one information frame group, and B1-B5
is set as one group of VT information frames, and a large number of such information frame groups are set. Each information frame group is a group in which information for one item is recorded.

A subject mark n is attached corresponding to the frame located at the beginning of each information frame group (first frame). In addition, there are films with only the item mark n attached to the first frame.In the frame with the 0 item mark n, information classified at a higher level is recorded, and in the frame without the 1 item mark n, , information categorized into lower levels is recorded.

FIG. 6 is a perspective view showing a general film league with a search device.

In this film league, when an operator searches for what kind of information frames are recorded on film F, the operator should feed film F one frame at a time while enlarging and projecting the image on microfilm F onto the screen. be.

The film supply cartridge 1 is a removable cartridge that accommodates a roll of colorful film F having a large number of frames f and marked with marks m and n. The microswitch 2 is a switch that detects that the cartridge l is installed in a predetermined position in the film league.

Also, a capstan roller 3 that feeds out the microfilm F in the cartridge L, a film feeding motor 4 that rotates the capstan roller 3, and a cartridge 1
The film winding motor 5 that rotates the film spool inside and the capstan roller 3 are connected to the microfilm F.
A solenoid 6 is provided to move the microfilm F to a position where it comes into contact with the microfilm F and a position where it moves away from the microfilm F.

In addition, pressure is applied toward the center of the take-up axis of the take-up reel 8 by the film guide rollers 71 and 72, the film take-up reel 8, and the spring 10.
A guide roller 9 that securely winds the leading edge of the film around the take-up shaft of the take-up reel 8, a film take-up motor 11 that rotates the take-up reel 8, and a predetermined film between the cartridge 1 and the take-up reel 8. A guide plate (not shown) for guiding the film F is provided along the feeding path.

Next, the operation of the above conventional example will be explained.

First, when the motor 4 is driven and the solenoid 6 is operated, the capstan roller 3 rotates and moves to a position where it contacts the film F.
The leading edge of the film is fed out of the cartridge 1 by contact with the microfilm F and the film F is fed toward the take-up reel 8 along a predetermined path. Feeding in this direction is called forward movement.

When the leading edge of the film F passes the guide roller 72,
A film detector (not shown) detects the microswitch F, and this detection signal causes the motor 11 to move gIA.
The take-up reel 8 rotates.

When the leading edge of the film F is fed to the take-up reel 8, the leading edge of the film is automatically wound around the winding shaft of the take-up reel 8 by the action of the guide roller 9. When wrapped, motor 4. The solenoid 6 does not operate, and the capstan roller 3 separates from the film F and returns to its original position. When the leading edge of the film F is wound around the take-up reel 8, the film F is transferred from the cartridge l to the take-up reel 8 by the rotation of the take-up reel 8.

When rewinding the microfilm F into the cartridge L, the motor 11 is stopped and the motor 5 is driven.The film spool in the cartridge L rotates in the direction to wind the film F, and the film F is rewound into the cartridge 1. . Feeding in this direction is called retraction.

Therefore, by driving either motor 5 or 11, the film can be moved forward or backward.

Furthermore, a lamp 12 that illuminates the microfilm F;
A condenser lens 13, a projection lens 14 that uses the lamp 12 as a light source to enlarge and project the image of frame f on the film F onto a screen (not shown), and a mark m provided near the frame of the microfilm F, the frame A known mark detector 15 for detecting mark n is provided.

This mark detector 15 has a photoelectric conversion element, and when the film F is fed, the light beam from the lamp 12 is blocked by marks m and n, and outputs a predetermined signal by detecting this light beam blocking. do. That is, when the frame mark m of the film F is detected, a frame mark signal is outputted, and when the frame mark n is detected, the frame mark signal is outputted.

FIG. 7 is a block diagram of a search device in the conventional example L.

The output signal of the input device 16 and the output signal of the mark detector 15 are input to the microcomputer 20 through the I10 circuit 21. The microcomputer 20 also controls the motors 4, 5, and 11 via the I10 circuit 22.

FIG. 8 is a flowchart showing the operation of the microcomputer in the conventional example.

First, when the Ttf power is turned on, the entire device is set to a predetermined initial state through the I10 circuit 22 (S L
), and checks whether or not a search signal has been input from the input device 16 (S2). If it has been input, the motor 4.5°6 is controlled via the I10 circuit 22, and the film F
is wound around the take-up reel 8 and the film is loaded (S3).

Then, frame-by-frame advance is performed to search for the first frame (S4), and the frame information is projected onto the screen through the magnifying lens 14. After that, if there is no search stop signal from the input device (SS) and film F is not the last frame (36), frame advance is performed and a single frame search is performed (S).
4).

In this way, the operator sequentially projects images onto the screen one frame at a time, and inputs each frame information to fi! I'm looking into what kind of information is stored there.

However, in the search method in the conventional apparatus described above, only one frame is projected on the screen.

In other words, since the operator cannot visually check multiple pieces of frame information at the same time, when comparing or contrasting multiple pieces of frame information, the operator must remember the previous and subsequent frame information each time, making observation of frame information cumbersome. There is a problem.
