Abstract

PURPOSE:To retrieve picture information in the unit of files easily and accurately when the picture information of the 1st recording medium is recorded on the 2nd recording medium by detecting the 1st and 2nd information of the 1st recording medium and generating index information based on the detected output. CONSTITUTION:When a frame mark detection signal enters a control circuit 36 when it is detected by a frame mark detector 351, and a frame mark counter is counted. Then the file mark of the head frame of the 2nd file is detected by a file mark detector 352 and a file mark detection signal enters the control circuit 36, then '1' is counted to a file mark counter. Then a frame mark detection signal enters the control circuit 36 by a frame mark and the frame mark counter is counted as 20. In this state, the information of 1 file and 20 frames is generated as the code information and, e.g., 1-20 code information and its head address are registered as index information. Further, the index information is registered sequentially at each file.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a recording method for reading image information on a $1 recording medium, such as microfilm, and recording the information on a second recording medium.

More specifically, the present invention relates to a method of creating an index signal corresponding to a film frame to be read and recorded.

[Conventional technology]

Conventionally, information such as documents that are generated in large quantities is space-saving.
Information was recorded at high density on microfilm, and necessary information was easily obtained from this microfilm.

On the other hand, in recent years, optical discs or magneto-optical disc devices capable of recording and reproducing at higher density have been developed as the above-mentioned file means and are attracting attention. That is, optical disks and magneto-optical disk devices (1) can store 20,000 to 30,000 sheets of A4 size image information on a disk-shaped recording medium (hereinafter referred to as a disk) with a diameter of 30 cm; and (2) are capable of random access during recording or playback. (3) Magneto-optical disk devices can erase and re-record unnecessary information (4) Since image information is converted into electrical signals, information can be searched in less than 1 second. It has various characteristics such as the ability to transmit files, and is now beginning to be used as a file means, replacing microfilm. However, when an optical disk device is used as a file device, an electrical reading device for microfilm image information is required in order to record and store information that has been previously filed on microfilm onto the disk. An example of this type of device will be described below.

FIG. 1 shows an outline of the above reading device.

A microfilm transport means is fixed to an intermediate plate 20 parallel to the bottom plate l of the main body of the apparatus. Also, on the bottom plate l is a halogen lamp 2) A lighting unit 5 consisting of a lens 3 and a mirror 4.
is attached, and its light beam illuminates the stage 6 on which the retrieved microfilm is stopped through the window of the middle plate 20. This illumination light flux forms an image on the pupil of the magnifying lens 7 in order to correct unevenness in light amount and improve efficiency. The image area of one frame of the illuminated microfilm is passed through a mirror 9 by a magnifying lens 7 fixed to a side plate 8 of the retrieval means to form an imaging surface of the microfilm on a plane A in the figure. On this imaging plane, a 5000-bit one-dimensional photoelectric conversion means (hereinafter referred to as COD) 10 is supported so as to be able to scan the imaging plane A along guide shafts 12 and 13 of a guide unit fixed to the back side plate 11. There is. Also, one-dimensional COD carriage 1
4 is connected to a wire 17 that is passed around a drive motor pulley 15 and a fixed pulley 16 arranged on the back side plate 11, and is reciprocated by the rotation of the drive motor 19.

The image information signal of the microfilm read from C0DIO by the above scanning is recorded on the optical disk device described below.

FIG. 2 shows an example of an optical disk device.

A spindle motor 22 is fixed to the bottom plate 21 of the main body, and a turntable of the spindle motor 22 has a Te0
A disk 23 carrying a medium such as X is locked.

In addition, a semiconductor laser 24, an imaging lens 25, a sensor 26
An optical head 27 holding a well-known optical disk recording and reproducing optical system is supported so as to be able to scan in the radial direction of the disk 23 on guides 30 fixed to side plates 28 and 29 of the main body.

Image information read by the microfilm image reading device is input to the optical disk device. The optical disk device uses the recording semiconductor laser 2 based on the image information or the image information compressed by a data compression circuit (not shown).
Modulate 4. The modulated laser beam is focused by the imaging lens 25 as a spot of about 14 m on the rotating disk 23, and its thermal energy causes the TeOx on the surface of the disk 23 to undergo a phase transition, forming pits with a different reflectance from the surrounding area. Information is recorded sequentially in the circumferential direction.

At this time, it is necessary to also record management information (hereinafter referred to as index information) of the image information in order to facilitate retrieval during playback by the disc device. However, since there is no numerical information for searching on microfilm,
No index information is provided in the image information input to the optical disk device. In addition, patent publications, etc.
Many of the various microfilms have several pages in one file format. However, creating and registering index information for each page causes problems such as loss of recording time and expansion of the index information recording area. .

〔the purpose〕

The present invention has been made in view of the above points, and detects the first and second information in the first recording medium and calculates the third information based on the output thereof. It is an object of the present invention to provide an image information recording system that enables accurate retrieval, shortening of recording time, and reduction of index area when image information of 1 is recorded on a second recording medium.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows the conveying means.

32 is a removable film supply cartridge that accommodates a roll of microfilm F having a large number of image frames and marks; 331. 332 is a film guide roller, 34 is a film take-up reel, 351 is a frame mark detector, and 352 is a file mark detector. Although not shown, a motor for rotating the take-up reel 34 and a mechanism for taking out the film F from the cartridge 32 are provided.

Moreover, everything other than the above is the same as the example in FIG.

Now, the film F is taken out from the cartridge 32 by a film take-out mechanism (not shown), and the film F is taken out by the guide roller 33.
+, 332, and is wound onto the take-up reel 34.

The film F has a large number of image information frames, a frame mark M recorded on each frame, and a file mark M recorded on the first frame of one file.

Mark m, M so-called B11p Mark, has a different density from the surrounding area, and the lamp 2 and each mark detector 351.

As the mark recording portion of the film F passes between the marks 352, the light incident on each mark detector 35+, 352 is blocked by the mark m, and a mark detection signal is transmitted to the mark detectors 351 . 352.

This mark detection signal is counted by the control circuit of the microfilm reading device of this embodiment.

FIG. 4 is a simple block diagram of the entire device.

36 is a control circuit composed of a CPU, etc., and 37 is a CGD.
AD the frame information of the microfilm read by IO
Conversion 1. An image processing unit that performs binarization, etc. and outputs it as electrical signalized image information to the outside, 35+ is a frame mark detector, 352 is a file mark detector, and the control circuit 36
A frame mark detection signal and a file mark detection signal are output respectively. Reference numerals 38 and 39 designate a film winding motor and its drive circuit 40, which is a disk device serving as the above-mentioned information recording and reproducing device.

Now, consider transferring all the frame information recorded on the cartridge 32 to an optical disc device.

The film F is loaded from the cartridge 32 as described above, a mark detection signal from the first frame mark is output to the control circuit 36, and the control circuit 36 stops the motor 39, thereby setting the first frame in the optical system. be done.

First, a file mark detection signal is input to the control circuit 36 at the file mark of the first frame of the l-th file, and a file mark counter in the control circuit 36 is set to "0". At the same time, a coma mark detection signal is input to the control circuit 36, and a coma mark counter in the control circuit 36 is set to 0''.

Then, the CCD 10 reads the frame information of the microfilm, and the image processing section 37 sends the information to the optical disk device 41.
The image information is transferred to the optical disc device 41, and the optical disk device 41 records the transferred image information.

When the transfer of the image information is completed, the control unit 36 starts the motor 39.
The mark of the 0th frame of the film F is detected by the mark detector 35, and a mark detection signal is sent to the control unit 3.
6, the control unit 36 stops driving the motor 39, thereby setting the second frame of the film in the optical system. − From now on, recording is performed on the optical disc device in sequence.

Further, when detected by the frame mark detector 35+, the frame mark detection signal is input to the control circuit 36, and the frame mark counter is counted until the file mark of the first frame of the second file is detected by the file mark detector 352. The file mark detection signal is sent to the control circuit 3.
6, "1" is counted in the file mark counter. At the same time, a frame mark detection signal is input to the control circuit 36 due to the frame mark, and the frame mark counter is counted to 20, for example. At this stage, information of 1 file and 20 frames is created as code information, for example 1
-20 code information and its start address are registered as index information. The location for registration may be the index area of an optical disk as shown in FIG. 5 or a floppy disk for index information management. After registration.

Set the frame mark counter to “0” again and
Image information is recorded in the same manner as described above until the file mark of the file is detected. After that, index information is registered for each file sequentially, and image information,
Continue recording and registering index information. Finally, when it is detected that there is no more image information using a well-known cassette end detection method, the value P of the file mark counter is set to P+
1, advance the value Q of the comma mark counter to Q+1, and (P
+1)-(Q+1) code information is created, index information is registered, and the process ends.

In the above embodiments, the file code of the first file is set to "1", but this is not the only option, and the operator can set this value arbitrarily (for example, 58-000001 in the case of a patent). It is also possible to use the file code as a serial number within one disc. Alternatively, the cassette number can be added as code information before the file code.

As mentioned above, the file code information is calculated using the file mark detection signal of B11p Mark, which is used as a microfilm search means, and the number of frames in the file counted using this code information and the frame mark detection signal is calculated. This is an excellent method that allows the registration of index information that is easy to search.

That is, when image information on microfilm is transferred to a disc, index information for each file can be automatically created and registered, making it easy to search for each file. Furthermore, there is no need to register index information for each frame, resulting in the effects of shortening the registration time and reducing the registration area.

Furthermore, although the above embodiment was explained using an optical disk,
A recording medium equivalent to a magneto-optical disk is also possible.

〔effect〕

As explained above, according to the present invention, the image information of the first recording medium is detected by detecting the first and second information of the first recording medium and creating index information based on the detection output. When the files are recorded on the second recording medium, searching in file units can be performed easily and accurately, and the recording time and index area can be reduced.
