Abstract

PURPOSE:To shorten the time of inputting recording instruction information by utilizing information on a recording medium used already in image recording process again in recording instruction information preparing process and preparing new recording instruction information in recording instruction information preparing process. CONSTITUTION:In the case of a reusing mode, the recording instruction information is prepared in a presently preparing recording instruction information recording medium A floppy disk 38 from an already recorded recording instruction information recording medium B floppy disk 39 and the read information of an image recorded in an analog recording medium and the inputted retrieving information. When a reusing mode is set in an input process, the read information already recorded in the recording instruction recording midium B is reused. Such a reusing mode is utilized when the kind of an image (for instance the kinks of a detailed account, drawing, photograph, etc.) to be digital recorded is the same with an image for which the recording instruction information is recorded. Thereby, it becomes unnecessary to input various read information directly by an operator, and the read information is recorded in the recording instruction information recording medium A in a short time.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to image processing in which images recorded on analog recording media such as microfilm and paper are read and digitally recorded on digital recording media such as optical disks and magnetic tapes. Regarding the method.

[Conventional” technology]

Filing OA (office automation) requires the following characteristics.

(1) High-speed human power of large amounts of information (2) High-speed reproduction (3) Legal evidence (4) Long-term storage (5) Uniformity of recording media standards (6) High resolution (7) High recording density (8) High speed Search (9)-ii! 1. , link with communications network (lO
(11) Ease of adding and updating Microfilm files are excellent in the above characteristics (1) to (7); , the optical disk file is as described in (7) to (1) above.
It is excellent in characteristics 1). Therefore, in order to complement the characteristics of both files, optical/micro integrated file systems have been proposed (for example, "Micrographics J
December 1984 issue, pages 17 to 22, Applied Mechanical Engineering J July 1984 issue, pages 76 to 81, JP-A-59-64855, JP-A-59-638
Publication No. 60).

When creating a microfilm file, you can carry the camera and take pictures without taking out the original, which provides excellent confidentiality. ), so when recording images that require confidentiality or images that can only be taken out for a short period of time on an optical disc, first create a microfilm file, then read the image with a microfilm scanner and transfer it to an optical disc. It is preferable to digitally record on an optical disc using a recording device.

However, images cannot be viewed directly with optical disk files, so when converting a microfilm file to an optical disk file, an operator must manually input search information, and when reading images and recording them on an optical disk. , the reading information necessary for reading this image, for example, the reading range of one image of microfilm, the resolution when converting to digital data (8 dots)/u, '16
It is necessary to set a threshold value for black and white discrimination (dots/dragons, etc.) or black and white discrimination.゛For this reason, the file conversion speed is slow,
It took about 500 pages/8 hours. Further, when such input work is performed, it is not possible to perform optical disc file search work, printout work, etc., and the operating rate of the expensive optical disc recording device becomes low, resulting in inefficiency.

Therefore, the present inventors have developed an image processing method for reading an image recorded on microfilm and digitally recording it on a digital recording medium. A step of creating recording instruction information to be recorded on a recording medium, and independently of the step, reading the reading information from the recording instruction information recording medium, reading the image recorded on the microfilm based on the reading information, and digitally recording it on the digital recording medium. devised an image processing method characterized by having a digital image recording step (unknown) 7 According to this image processing method,
Both processes are independent, and the speed at which the recording instruction information created on the recording instruction information recording medium is read is much faster than the speed at which the operator inputs this information into the recording instruction information recording medium. microfilm images can be digitally recorded all at once onto a digital recording medium. 7 [Problems to be Solved by the Invention] However, since there are many types of reading information among the recording instruction information, the input time becomes long, especially when different reading information is input for each document.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide an image processing method that can shorten the input time of recording instruction information.

[Means for solving problems]

In the present invention, recording instruction information consisting of reading information necessary for reading an image recorded on an analog recording medium and search information for searching the image recorded on a digital recording medium is stored in the recording instruction information recording medium. Image processing that includes a step of creating recording instruction information on AI, and an image recording step of reading the recording instruction information, reading an image recorded on an analog recording medium and recording it on a digital recording medium according to the information. In the method, in the case of the reuse mode, the recording instruction information creation step includes, from the recorded record-instruction information recording medium B, image reading information recorded on the analog recording medium and manually searched information. The feature is that the recording instruction information is created on the recording medium that is currently being created.

Furthermore, in a mode in which read information and search information are created on separate recording media, only the search information is newly created, and the read information is reused as is or with some modifications.

[Effect]

During the input process, when the reuse mode is set, the read information already recorded on the recording instruction information recording medium B is reused. Further, in a mode in which read information and search information fit are created separately on a recording medium, search information is newly created, and read information is reused as is or with only some necessary minimum modifications.

This eliminates the need for the operator to directly input various types of read information, and the read information can be recorded on the recording instruction information recording medium A in a short time.

This reuse mode is particularly useful when the type of image to be digitally recorded (for example, type of specification, drawing, photograph, etc.) is the same as the type of image for which recording instruction information was recorded in the past. It is used for famous baths.

〔Example〕

First, an overview of a file conversion system to which the present invention is applied will be explained with reference to FIG.

A document 10 is shaped into a bird shape by a camera 12, and the exposed microfilm is subjected to a processing process 14 such as development, fixing, and washing to create a readable microfilm 16. The microfilm 16 includes a 16B roll microfilm 1B, a 35mm roll microfilm 20. There are a microfiche 22, an aperture card 24, and the like.

The bird-shaped work can be carried out by taking the camera 12 to the location where the original 10 is located, and there is no need to take the original 1o out, which provides excellent confidentiality and prevents the loss of the original.Even if it is taken out, it can be done in a short period of time. Manuscript 10 can be returned. Also,
Faster input compared to input to an optical disk (e.g. 5ooo~
10,000 pages/8 hours, which is approximately 10 to 8 hours when directly reading a document 10 with a scanner and recording the image on an optical disc.
20 times), so even if you take it out, you can return 10 manuscripts in a short period of time. Since the images on microfilm can be viewed visually, all you have to do is input the search information after the bird shape, but images recorded on optical discs cannot be viewed visually, so the search information must be input at the same time as the images are recorded. Furthermore, microfilm has excellent legal evidence and long-term preservation.

For this reason, it is preferable to create a microfilm file and then convert only the necessary images into optical disc files, rather than directly reading the image of the original 10 to create an optical disc file.

The microfilm 16 is loaded into a kit 2G according to its type, and installed in the microfilm reader 2B. The microfilm reader 28 is equipped with a screen 30, and the image of the microfilm 16 is displayed on the screen 30.
projected on. Frame feeding of the microfilm 16 is performed in response to input signals from the keyboard 34, and frame addresses and the like are displayed on the CRT display 36. The operator, while looking at the image projected on the screen 30 or without looking at the memo, inputs recording instruction information (for example, search information and reading information) of the image to be converted into an optical disk file. do. This recording instruction information is displayed on the CRT display 36. .

Of the recording instruction information, read information is recorded,
Floppy disk 3 as recording instruction information recording medium B
If there is any read information that is the same as the read information stored in 9, it is read and reused to reduce the amount of human labor required. Furthermore, when the read information and the search information are created separately on the recording medium, only the search information is newly created, and the read information is reused as is or after making the minimum necessary modifications. The input recording instruction information is checked for errors and recorded on the floppy disks 38 and 39 after the errors are corrected.

On the other hand, independently of the above steps, the conversion of microfilm files into optical disk files is automatically and continuously performed. That is, the kit 26 and floppy disk 38 that have been processed by the microfilm reader 28 are loaded into the microfilm scanner 40 and file controller 41, respectively. The image on the microfilm 16 loaded in the kit 26 is projected onto the screen 44, read by the line sensor 42, digitized, and supplied to the file controller 41 of the optical disk recording device 52 via the wiring 50.

The recording instruction information recorded on the floppy disk 38 is read by the file controller 41 and supplied to the microfilm scanner 40 via the wiring 50, and the microfilm scanner 40 performs frame feeding of the microfilm 16 and the above-mentioned projection according to this recording instruction information. , digitalization, etc. Digital image data from the microfilm scanner 40 and search information from the floppy disk 38 are processed by a file controller 41 and recorded onto an optical disk 54. Further, this search information is recorded on a recording medium other than the optical disk, such as the floppy disk 55, and is used for high-speed search of optical disk files. The recording instruction information and digital image data are each CR
0 displayed and monitored on the T display 56
Operation signals such as start and stop of work are input via the keyboard 58 and supplied to the file controller 41.

For example, the microfilm reader 28 (inexpensive) is distributed and provided at a plurality of companies, and the optical disk recording device 52 (expensive) is provided at a central location.

Next, the microfilm reader 28 will be explained in detail according to FIG.

In this example, the microfilm 16 is a roll microfilm 1B, and the roll microfilm 18 wound around the supply reel 60 is pulled out and wound onto the take-up reel 62. Pulled out roll microfilm 18
The middle part of is held between the pressure bonding glass mechanism 64,
The image projected onto the screen 30 is not distorted.

The light from the light source 66 is irradiated onto the roll microfilm 18 through a condenser lens 68, transmitted through the roll microfilm 18, and an image of the roll microfilm 18 is projected onto the screen 30 through an imaging lens 70.

Supply reel 60. The take-up reel 62 is rotated by a drive signal from a drive circuit 72 being supplied to a motor (not shown).
The rotation of the winding wheel 62 is detected by a pulse generator 74, and one pulse is output from the pulse generator 74 every time the winding wheel 62 rotates by a small angle.

At the same time as the original 10 is drawn on the roll microfilm 18, as shown in FIG. Blip mark 124 is exposed. The address of piece 120 is page blip mark 122 and file blip mark 124
It can be detected by counting sequentially.

As shown in FIG. 3, the page blip mark 122 and the file blip mark 124 are detected by two blip mark sensors (optical sensors) 76.

The signals from the pulse generator 74 and the blip mark sensor 76 are input to the microcomputer 78 (8G).
output port 8 of the microcomputer 78.
2 supplies the control signal for the motor to the drive circuit 72. The operator looks at the image projected on the screen 30 or looks at the memo, operates the keyboard 34, and inputs recording instruction information into the input board 80. In this case, if the read information recorded on the recorded floppy disk 39 is to be reused because the two types (types of images such as specifications, drawings, photographs, etc.) are the same, etc. Instead of inputting reading information, search information for the image corresponding to the address is input. This recording instruction information is supplied from the output port 82 to the CRT display 36, and the input information is confirmed. Further, the address of the projected image is displayed on the CRT display 36. A control signal and recording instruction information are supplied from the output port 82 to the floppy disk driver 84, and this recording instruction information is recorded on the floppy disk 38. Also, the recording instruction information already stored on the floppy disk 38 is supplied to the input capacitor 80 and read, and additional information is added to the stored recording instruction information.
It is possible to insert, delete, correct, etc.

'Furthermore, in the reuse mode, predetermined read information already stored on the floppy disk 38 is supplied to the input port 80 and read by the microcomputer 78, and then this read information is recorded on the floppy disk 38. Ru. The microcomputer 78 is a CPU86,
Equipped with ROM88 and RAM90, CPU86 is R
The RAM 90, which performs processing such as input/output according to the program stored in the OM 88, is used for temporary storage of recording instruction information and for working purposes.

Furthermore, the reason why read information can be reused will be explained with reference to FIG. Each time the file blip mark 124 described above is detected, if one file unit corresponds to one specification, it is converted and recorded as a document on a digital recording medium.In normal use, a page in the l file is recorded. Even if the number of preps, i.e., the number of pages in a document, is completely unknown from the beginning, the purpose is to process each file as one document, and the read information such as the size of each page is If it is sufficient that the search information is the same, then by creating only the necessary search information for each document, the reading information can be reused by setting the above-mentioned reading information in advance.

Next, the software configuration of the microcomputer 78 will be explained according to FIG.

First, in step 150, the floppy disk 3
8 into the floppy disk driver 84.

Next, in step 152, if the operator determines that it is necessary to load the microfilm 16, that is, if the operator projects the image onto the screen 3o and inputs recording instruction information while using TsU2L, the operator proceeds to step 154.
Load this with.

If the recording instruction information is memorized at the stage of photographing the original 10 with the camera 12, there is no need to load the microfilm 16, and the existing microfilm 1 is created without considering the necessity of digital recording. For '6, loading the microfilm 16 may be necessary.

Then, in step 156, the operator selects a processing mode. This processing mode includes a new creation mode in which recording instruction information is created on a new floppy disk 38, and an additional update mode in which recording instruction information is added or updated to a floppy disk 38 in which recording instruction information is already stored. .

When the new creation mode is selected, in step 158, the floppy disk 38 is initialized (formatted).
will be held. In addition, the operator can use the CRT display 3
6 and select the type of microfilm 16 and frame search mode.

Types of this roll microfilm include the roll microfilm 18, 35, dragon roll microfilm 20, microfiche 22, aperture card 24, etc. shown in FIG.

In the case of the microfiche 22, the number of vertical and horizontal frames and the number of header rows are also specified. In addition, the piece search mode includes, for example, in FIG. 3, a mode in which the number of page blip marks 122 alone is counted to specify a piece, a mode in which the number of file blip marks 124 is counted first, and a file blip mark 124 counted in the end is counted. There is a mode in which the number of page blip marks 122 is counted from the position of the mark 124 to search for a piece.

By selecting the type of microfilm 16 and the frame search mode, the search method for the frame to be projected is determined. This initial configuration information is based on key personnel
In the case of the additional update mode, the data is read from the floppy disk 38 and written to the RAM 90.

Next, in step 160, the address of the frame (converted frame) to be recorded on the optical disc 54 is specified according to the frame search mode selected in step 158. In this case, multiple pieces may be specified at the same time, and this address is one piece of read information.

Next, if the microfilm 16 is loaded in the microfilm reader 2 (step 162), the frame at the address specified in step 160 is searched for in step 164. When this piece is found (step 165), its image is projected onto the screen 30 in step 166.

Next, in step 167, it is determined whether reuse mode is set. If this mode is not set, the operator can view this projected image in step 168 and perform the next steps required when reading the image with the microfilm scanner 40. Enter the reading information such as .

(1) Reading sizer: Depending on whether the document before it is bird-shaped on the microfilm is, for example, A4 or A3, the image captured on the microfilm will be vertically or horizontally long (see Figure 3). .

This determines the range to be read by the microfilm scanner 40 when converting to an optical disk file.

(2) Reading resolution A resolution switching circuit 112 (FIG. 5) to be described later determines whether to switch to, for example, 8 dots/Tsuru or 16 dots/Dragon.

(3) Black and White Judgment Threshold This is a threshold for determining whether pixel data is white or black in the binarization circuit 108 (FIG. 5), which will be described later.

Threshold setting modes include automatic mode in which the threshold is automatically set by detecting the amount of projection light, manual mode in which the operator determines and sets the threshold by looking at the projected image, and locking the setting value so that the same threshold is set every time. There is a lock mode to set the value, and you can select one. When in manual mode, also input the threshold value.

Note that the above example is for binarization, but even when halftones are used, the shading can be adjusted using mode settings such as auto, lock, or manual, and in manual, light or dark depending on the shading of the original image. Also enter the step-by-step settings.

(4) Reading range This is the reading range when only a part of one projected image is converted into an optical disk file.

This range specification mode includes a trimming mode in which the set range is read, and a masking mode in which the outside of the set range is read, and the user selects one of these modes and inputs the reading range.

(5) Image polarity Determine whether to read the image stored on the microfilm 16 as it is (positive) or with black and white reversed (negative).

(6) @Same number of sheets to be taken - Set how many sheets to read using the reading information ((1) to (5) above).

Note that all the frames within the address range input in step 160 may be set as the number of sheets to be read.

If it is determined in step 167 that the reuse mode is set, the process proceeds to step 169, where the operator inputs search information, which will be described later, in place of the various read information described above.Next, in step 170, the operator 78 reads read information from the floppy disk 39, and is used as the same information as the read information input in step 168 above.

Therefore, by inputting one type of information called search information by the operator, it becomes the same as inputting the read information in (1) to (6) above in step 168, and the input time by the operator is shortened. In particular, if different reading information needs to be entered for each document, this input time is significantly reduced.

After completing the process of step 168 or step 170,
Next, the process advances to step 172, and if the input of recording instruction information has not been completed for each document, the processes of steps 160 to 170 are repeated. Here, the document unit may be a plurality of documents; It means not on the way. Further, the -document is, for example, a range (such as a specification) delimited by the file blip mark 124 in FIG. 3.

If it is determined in step 165 that the frame at the address specified in step 160 was not found in step 164, the process proceeds to step 174, and an address specification error is displayed on the CRT display 36. Then, the process returns to step 160 and the address is input again.

If it is determined in step 172 that reading information has been input for each document, the process proceeds to step 176, where search information (keywords, etc.) for searching the image after it has been digitally recorded on the optical disc 54 is input. Keywords are entered for each document. -By entering multiple keywords into a document, you can search from various angles.

Next, if the microfilm 16 is loaded in the microfilm reader 2B (step 178), the content of the read information manually entered in step 170 is checked in step 180 while feeding the microfilm 16 frame by frame.

This includes the following checks:

(1) Microfilm address check step 1
It is checked while performing a film search whether a frame corresponding to the microfilm address specified in step 60 exists.

(2) Reading size setting error check This is the page blip mark 12 of the projected piece.
2 and the page blip mark 122 of the previous frame (see FIG. 3), and compare this distance X with the width of the image determined by the reading size input in step 170. Determine whether the read size is reasonable. The distance X between the page blip marks 122 is measured by counting pulses from the pulse generator 74.

(3) Black and white judgment threshold setting error check The appropriate range of this threshold is stored in advance in the ROM 88.
In step 170... it is checked whether the set threshold value is within this range.

Note that the validity of the set threshold value may be checked using the detected value of the amount of projection light.

(4) Reading range specification error check This calculates the maximum readable range of the frame image from the interval between the page blip marks 122, and checks whether the reading range input in step 170 is included in this maximum range. .

If there is no error in the input contents (step 182) and input of recording instruction information has not been completed for all converted frames (step 184), the process returns to step 160 and the input process is repeated.

If it is determined in step 182 that there is an error in the input content, the error content is displayed on the CRT in step 186.
The process is displayed on the display 36, and the process returns to step 170 to input the corresponding recording instruction information again. If an error occurs that requires searching for the designated frame of the microfilm again, the process returns to step 160 (not shown).

For input items that are not shown in FIG. 4 but do not require correction, the correction process is performed while skipping the corresponding steps.

When it is determined in step 184 that the process of inputting the recording instruction information using the keys manually from the keyboard 34 has been completed, in step 188 the recording instruction information stored in the RAM 90 is recorded on the floppy disk 38 via the floppy disk driver 84. do. If the addition/update mode is set in step 156, additions and changes are made when recording onto the floppy disk 38.

Next, in step 190, the operator takes out the microfilm 16 and the floppy disk 38 from the microfilm reader 28, and the process of recording the recording instruction information on the floppy disk 38 is completed.

If the microfilm 16 is not loaded into the microfilm reader 28 in the above process, the input content of the recording instruction information is checked on the CRT display (
(not shown). If it is necessary to check the input contents of the recording instruction information with high accuracy, the microfilm 16 is loaded into the microfilm reader 2nd, and the process of step 180 shown in FIG. 4 is performed. In this case, an affirmative determination is made in step 184. In FIG. 4 shown as an example, the recording instruction information creation step and the checking of the created recording instruction information are shown as a series of processes, but it goes without saying that they can be performed as separate steps. In that case, the former process may be performed without using microfilm, and the latter checking process may be performed using microfilm.

Next, according to FIG.
will be explained in detail.

Components that are the same as those shown in FIG. 2 are given the same part numbers as those used in FIG. 2, and are given the letter A, and their explanations will be omitted.

Image projection onto the line sensor 42 and screen 44 is performed by rotating a mirror 92.
is sub-scanned by Further, an automatic exposure sensor 100 is disposed toward the optical path of the projection light, and the amount of light transmitted through the film is detected and supplied to the input boat 80A via the A/D converter 102. The signal from the automatic exposure sensor 100 is used to adjust a light amount diaphragm mechanism (not shown) or adjust the lamp voltage to change the amount of light.

The line sensor 42 is composed of, for example, a COD, and is main-scanned by a transfer pulse from the main-scanning/reading circuit 104, and charges proportional to the amount of light received by the elements of the line sensor 42 are sequentially supplied to the main-scanning/reading circuit 104. This is converted into a voltage and supplied to the A/D converter 106.

The signal converted into a digital value by the A/D converter 106 is supplied to the binarization circuit 108, compared with the threshold value from the microcomputer 78A, converted to a value of 1 or O, and sent to the line buffer 110 as 1. Bits are supplied sequentially. When switching the resolution, when two lines of data are supplied to the line buffer 110, this is supplied to the resolution switching circuit 112, and the microcomputer 78
16 dots/Tsuru to 8 dots/by switching signal from A
The resolution can be switched to Tsuru. 2(li) data is supplied to the file controller 41 via the interface 114. Furthermore, control information is exchanged between the file controller 41 and the microcomputer 78A via the interface 118.

The microfilm scanner 40 operates based on control commands from the file controller 41, and the control commands are supplied from the file controller 41 via the interface 118.

Next, the software configuration of the microcomputer 78A and the file controller 41 will be explained according to FIG. As shown in FIG. 7, this software scans a document 10 for multiple lines (scanning lines 11) at regular intervals to sequentially read the pixel density, and uses this as a sample to check the degree of overall shading of the document image. Determine the value threshold,
An image is recorded on the optical disc 54. Furthermore, if the level difference between the light and shade of the entire image is less than a certain value, an abnormality display or an alarm sound is generated to notify the operator, and the operator can decide whether to skip reading or record on an optical disk.

This process is performed in a preliminary scan prior to the read scan to determine the threshold value. This preliminary scanning is performed by the microfilm scanner 40 in response to a reading instruction from the file controller 41. However, if reading is performed continuously and it is necessary to determine the threshold value depending on the density of the image each time, it is necessary to scan the target film frame. Efficiency is increased by doing this during the return scan of the line sensor after the movement to is completed.

In step 300, the recording instruction information is read from the floppy disk 38 and transferred to the RAM 90A.6 Next, the process proceeds to steps 301 and 302, and the value of i indicating that the image density sampling is the first sampling is set to O.
shall be. Next, the process proceeds to step 304, where the address of the converted frame is read from this recording instruction information and the roll microfilm 18 is moved so that the converted frame is located at the pressure bonding glass mechanism 64. Then, the process proceeds to step 305, in which the converted frame is projected onto the screen 44, and the digit 1 of the scanning line 11 and the number of pixels to be sampled are determined according to the reading size and the partial reading range of one image, which are the recording instruction information. Determine N. Next, the process proceeds to step 306, where the sub-scanning mechanism 98 moves at a faster speed than when converting into an optical file.
start.

The process then proceeds to steps 308 and 310, where the image density is read from the A/D converter 106. Initially, i=Q, so proceed to steps 312 and 314, and the maximum concentration DHAI
, the minimum density DMIN is Do.

Next, the process proceeds to steps 316.308 to 312.318, where the maximum density D□8 and the image density are set.

Compare the values of (i=1) a If DMAX < DI, proceed to step 320 and set the value of image density DI to the maximum density DHAM * If DMIN > DI, proceed to steps 318, 322, 324 and image Let the value of the density D1 be the minimum density D , , a DIlA11-DI
or D□8-D, the process proceeds to step 316 without changing the values of the maximum density DMAX and minimum density DHIN.

If the difference between the maximum density D is the maximum concentration DHAI+ and the minimum concentration. When the difference of 1N becomes greater than or equal to Δ, the process proceeds from step 316 to step 325, where a black and white discrimination threshold is determined based on a predetermined known method, and the process further proceeds to step 326, where the line sensor 42 is moved to the initial position for image reading. move at high speed. This initial position is determined by the recording instruction information stored in the RAM 9OA. For example, if the reading range of image i is specified, the image will be moved to the initial position of the reading part.6 Next, the process proceeds to step 328, and while moving the line sensor 42, the converted frame is determined by the threshold value of step 325. Read image, interface 1
The digital image data is supplied to the file controller 41 via 14. The file controller 41 records this onto the optical disc 54. Further, the file controller 41 records the search key item out of the recording instruction information from the floppy disk 38 onto the optical disk 54 and the floppy disk 55 for each converted frame.

If the number of samples of image density is larger than the preset value of N (in the example of FIG. 7, four times the number of pixels in one row), it is determined that there is no image, and the process moves from step 308 to step 330. Go forward and send the image abnormality signal to interface 11.
8 to the file controller 41 and the CRT
Displaying an image abnormality on the display 58 Next, the process advances to step 332 and waits for the operator to act on the keyboard 56 while looking at this display and the image projected on the screen 44.

In addition to displaying information on the CRT display, the means for notifying the user of an abnormality may include generating an alarm sound or the like. Further, it may be possible to select a mode in which to always wait for an operator's instruction or to automatically skip reading when an abnormality occurs.

If the sampled scan lines 11 happen to be of approximately the same density and an image has been recorded between the scan lines 11, the operator presses the record image key on the keyboard 56, which advances to steps 334, 325, and 326. , proceed to normal recording processing.

If the operator determines that there is no image, the process returns from step 334 to step 301. That is, the non-image is not recorded on the optical disc 54 and is skipped.

Therefore, unnecessary non-images will not be recorded on the optical disc 54, and since sampling of image density is performed for images in the designated reading range, a reading range in which no image exists will be accidentally designated. You can discover things at this stage.

When the above processing is repeated and images of all converted frames are sequentially recorded on the optical disk 54, step 301
At , it is determined that the recording process has ended, and the above process ends.

In the present invention, the floppy disks 38 and 39 as the recording instruction information recording media A and B may be a single floppy disk upon reconsideration, since floppy disks generally have a large storage capacity.

In this case, for example, it is sufficient to mount only the floppy disk 38 on the floppy disk driver 84, which simplifies handling.

Further, the recording instruction information recording medium B may be one in which the recording instruction information has already been input at the current input time.
It may be the RAM 90 itself into which the recording instruction information was input immediately before.

Further, the recording instruction information recording media A and B may be magnetic tapes, tapes, punch cards, mark sheets, etc., as long as they are readable after recording.

The recording medium for recording the recording instruction information is not limited to a floppy disk, but may be a magnetic tape, a tape, a RAM with a backup battery, etc. as long as it can temporarily store the information.

Further, the analog recording medium is not limited to microfilm, but may be paper that can be continuously processed, such as paper fed by an auto feeder.

Furthermore, digital recording media are not limited to optical discs;
It only needs to be able to record digital signals, and may be a magnetic tape or the like.

In addition, the line sensor 4 is attached to the microfilm scanner 40.
Separately from 2, an inexpensive area sensor with a relatively small number of pixels may be provided, and only electrical scanning may be performed without performing mechanical sub-scanning in the sampling process.

Further, the microfilm reader 28 may be provided with a line sensor or the above area sensor to determine whether there is an image.

〔Effect of the invention〕

In the image processing method according to the present invention, read information is reused among recording instruction information that has already been input, and instead of inputting various types of read information, the recording instruction information to be reused is Of these, only one type of information, namely image search information, needs to be input, which has the excellent effect of significantly shortening the input processing time for recording instruction information.
