DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data generating apparatus for generating data for searching a roll-shaped microfilm and a searching apparatus for performing a search based on the generated data.

[0002]

2. Description of the Related Art Conventionally, a retrieval apparatus corresponds to one screen of a roll-shaped microfilm and one screen, and a mark for retrieval is:
A square mark is imprinted in the vicinity of the film side edge, and the number of images is counted by detecting this mark, or an image is stopped at a projection position.

[0003]

However, in the above conventional example, there is a case where dust adheres to the film and is erroneously recognized as a search mark. In addition, in the case of repeated use, there is a case where a scratch is formed on the film and accurate search cannot be performed. In general, there are a large number of images on a film, and if a count error is made on the way, errors may be accumulated during repeated round-trip search.

To prevent this, there is also a system (Kodak IM code) in which a page is copied into a search mark area with a bar code for each block, but in this case, an area having a large IM code is used. As a result, high-density shooting of images has become impossible. As for the system that uses such a mark for search, a system such as unmanned frame search on the film and automatic copying can be used, but the mark error detection as described above has been made. The disadvantage was that complete unattended operation could not be performed.

The operation of this embodiment having the above configuration will be described with reference to the flowchart of FIG.

First, a corresponding address is input by the input device C to a position on the film where the first subject placed on the placing tray 2 is to be imprinted. At this time, the address is set (S1-1), and the counter D is reset to 0 (S1-2).

Next, the roller pairs 4 and 5 and the feed roller 7 are rotated, and the subject 3 is separated by one and sent to the photographing unit 9. At this time, it is detected that the subject has been sent when the tip of the subject passes through the subject detector B.
When the subject is detected (S1-3), the film control unit H

Then, the image of the subject sent to the photographing section 9 is photographed on the film 17, and at the same time, the mark imprinter F
The mark for search is printed on the film (S
1-5). At this time, the number of pages is stored in the memory E.

At the time when the mark is imprinted, the pulse transmitted from the encoder A with the transfer of the film 17 is started to be measured by the counter D (S1-6).

On the other hand, the subject is ejected by the ejection rollers 21 after photographing. At this time, when the rear end of the subject passes the subject detector B, it is detected that the subject has passed the photographing unit. When the passage is detected (S1-7), the film controller H stops the film 17 (S1-7). S1-
8).

At this time, the measurement by the counter D is completed, and the obtained count number, that is, pitch information, and the initially set address, that is, the current address, are written in the memory E (S1-9).

Then, the address is updated by the address generator (S1-10), and the counter D is reset again (S1-2). Hereinafter, shooting is similarly performed from the second subject.

In this manner, data relating to the address and pitch information as shown in FIG. 4A and the photographed film 17b as shown in FIG. 4B are obtained.

In FIG. 4A, reference numeral 23 denotes each photographed image, 24 denotes a mark, and P denotes pitch information. Note that this pitch information is obtained when an encoder that generates pulses in synchronization with the film at intervals of about 0.1 mm is used at the time of film running photography.

C is pitch information, D is other search information, and the content is not described here. The characteristic feature is that pitch information is written in addition to the address corresponding to each page.

When using a splice tape,
After connecting the film to the film, the pitch information at the connection point is corrected.

In this embodiment, a rotary camera is used as a photographing device, but a flat-bed camera may be used.

Although the pitch information is stored in the memory E, it may be optically recorded directly on the film 17 as other storage means, or may be magnetically recorded at the head or tail of the film 17. The information may be automatically loaded into the search device when loaded into the search device. Also, pitch information may be taken into a large computer as another storage means. In addition, a method of optically printing pitch data on the film 17 may be considered as a storage means.

Next, a description will be given of a case in which a photographed film is searched based on the data thus obtained. Here, the search for transporting the film in the forward direction will be described. The forward search is a case where the search address is larger than the start address. Since the search in the reverse direction is performed in the same manner as in the forward direction, the description thereof is omitted here.

FIG. 5 shows a schematic configuration of a retrieval device 31 used. Reference numeral 32 denotes a photographed film 17 located at a projection section 35 between a lower guide glass 33 and an upper guide glass 34.
This is an illumination lamp that illuminates the image 23b through the condenser lenses 36 and 36a. A projection lens 37 projects the illuminated image 23 on a screen 38. Also, 39
Is a supply reel, 40 is a take-up reel, and 41 and 42 are guide rollers. L is an encoder that generates a pulse in synchronization with the guide roller 41, and M is a mark detector that detects a mark imprinted on a photographed film.

FIG. 6 is a block diagram of the search device 31. The encoder L and the counter W constitute a measuring means Y. N
Is an input device such as a keyboard for inputting an address of an image to be searched, that is, a search number; P is an erase key for inputting an address to be erased; Q is an address generator;
Is a mark count unit, S is a film control unit, W is a counter, T is a control unit, and U is a storage unit that stores a correspondence table between addresses and pitch information created by a photographing device as the data creation device. As a memory.

The search by the search device 31 having the above configuration will be described with reference to the flowchart of FIG.

First, the address of the image currently located in the projection unit 35 is input through the input device N, and the current address is set in the control unit T (S2-1). However, when the current address is 1, no input is made.

Next, the address of the image desired to be searched is input by the input device N (S2-2). Then, the take-up reel 40 is operated by the film control unit S, and the transfer of the film 17b in the forward direction X is started (S2-3).
At this time, a pulse emitted from the encoder L is measured by the counter W in synchronization with the guide roller 41, and the pitch is read (S2-4). At the same time, the difference from the pitch information stored in the memory U is determined. Subtraction is performed until the value becomes equal to or smaller than the allowable value χ (S2-5). It is better that the allowable value χ is as small as possible, but it is set to an appropriate value depending on the accuracy of the encoder L. When the difference between the pitch information and the read pitch becomes equal to or smaller than the allowable value χ (S2-6),
It is checked whether or not the mark detector M has detected a mark corresponding to the next adjacent image (S2-7). If the mark has been detected, the address is updated by the address generator Q (S2-9). Since the difference between the stored pitch information and the read pitch is equal to or smaller than the allowable value χ, the mark should normally be detected. However, the mark may be skipped due to the low density of the mark or the weak light amount of the illumination lamp. At that time, the difference between the pitch information and the pitch becomes a negative value. Therefore, when the difference between the pitch information and the pitch becomes -χ or less (S2
-8) The address is updated assuming that the skip has occurred (S2-9). Then, it is compared whether the updated address matches the desired address (S2-1).
0), if they do not match, return to step S2-4,
Steps S2-4 to S2-9 are repeated until they match. If the addresses match, the film control unit S
Stops the film (S2-11), and the search ends.

The effect of the retrieval device having the above configuration and operation will be described below.

For example, FIG.
As shown in (c), in the case where the unnecessary noise area 50 is included, in the conventional search device, the unnecessary noise area 50 is regarded as a mark and an erroneous search occurs.
Search using the memory U created by the data creation device
The search device that performs
Search is performed. That is, the fill shown in FIG.
Mark 17 of the image address N + 2 of the program 17b and the next image
The pitch information P between the marks 24 of the address N + 3 is Pn +
2 is stored in the memory U.
Since the unnecessary noise area 50 is skipped in step S2-6 between the address N + 2 and the image address N + 3 , a correct search is performed.

On the other hand, even when the mark is imprinted thinly, the address is updated as the presence of the mark in steps S2-8 and S2-9, so that a correct search is performed.

The following are conceivable causes of the unnecessary noise area. Dust, splice tape connection point, non-photographing part development at camera with automatic developing machine, IM code in some cases.

Next, a case in which data is rewritten in the search device 31 in order to exclude a predetermined image on the film from the search target will be described with reference to FIGS. 6, 8 and 9. FIG.

First, the address of an image to be excluded from the search target (hereinafter referred to as an erasure address) is input by the input device N. For example, address [A], that is, 11007 is input (S3-1).

Then, by pressing the erase key, the sum [C] of the pitch information [b] of [B], which is the address immediately before the erase address, and the pitch information [a] of the erase address [A] is obtained. Is changed to the pitch information of the address [B] (S3-2). At this time, the pitch information of the erase address [A] is changed to 0 (S3-3).

In the case where the search is performed based on the rewritten data from FIG. 9 (b) to FIG. 9 (c),
This will be described with reference to FIGS. The description of the steps described above is omitted.

After executing steps S2-1 to S2-3, in step S2-4, the pitch information of the address of the image currently located in the projection unit 35 is read. If the pitch information is a value other than 0, it is determined that data has not been rewritten, and normal steps, that is, steps S2-5 to S2-11 are executed. On the other hand, if the pitch information is 0 (S2-4-1), the next operation is performed assuming that the data at that location has been rewritten.
First, the control unit T checks whether the address matches the search address.
(S2-4-2). If the address where the pitch information is 0 does not match the search address, the address is updated there (S2-9) and the normal search routine is started. Here, the reason for updating one address is to prevent the address from being shifted by compensating for the address of the image excluded from the search target. On the other hand, if the address where the pitch information is 0 matches the search address, it means that the image excluded from the search target was specified by mistake, and the specified address is not used. Is displayed (S2-4-
3) Terminate the search.

Next, a data generating apparatus according to a second embodiment of the present invention will be described. In this embodiment, a search device is used as a data creation device. That is, the first
In this embodiment, data is created at the time of photographing, whereas in the present embodiment, data is created by using photographed film after photographing.

The configuration of the search device 31 'of this embodiment is the same as the configuration of the search device 31 described above, and thus the description thereof will be omitted, and its operation will be described based on the flowchart of FIG.

First, the film is set in a rewound state so that the leading image of the photographed film is located at the projection unit 35. Then, the head address is input from the input device N (S4-1). Then, the transport of the film is started by the film control unit S (S4-2). When the mark corresponding to the leading image is detected by the mark detector M (S4-3), the pulse emitted from the encoder L is sent to the counter W by the counter W. When counting is started (S4-4) and the mark detector M detects a mark corresponding to the next image (S4-5), the obtained count number is stored in the memory U as storage means as pitch information of the first address. Write (S4-6). At this time, the count number measured by the mark count unit R is written in the memory U as the number of pages. Then, one address is updated by the address generator Q (S4-7), and the counter W is reset (S4-8). Then, the generation of the pitch information of the next image is repeated in the same procedure. Then, when the end of the film is reached (S4-9), the creation of the data ends.

As described above, according to this embodiment, FIG.
Data as shown in (b) is created, and the same effect as in the first embodiment can be obtained at the time of retrieval.

[0047]

As described above, by performing a search based on the data created by the data creation apparatus of the present invention, it is possible to find a case where there is an unnecessary noise area between the marks that is erroneously recognized as a mark. Even if there is, an unnecessary noise area is skipped and a correct search is performed.
