〔Example〕

First, an outline of an image processing apparatus according to an embodiment of the present invention will be explained based on FIG.

In this image processing apparatus, only necessary images of the images recorded on the roll microfilm 16 as an analog recording medium are recorded on the optical disc 28 as a digital recording medium.

Auto stocker IO has cassette films 12A and B.
, C, . . . are stored therein, and a designated cassette film 12K is automatically taken out and loaded into the microfilm scanner 14.

Among the images on the roll microfilm 16 housed in the cassette film 12K, the image at the reading position is projected onto the screen 18, and the image is read by the line sensor 20 and binarized. There is. A floppy disk 22 as a search information recording medium is loaded into the microfilm scanner 14. Search information is recorded on the floppy disk 22 in correspondence with the roll number of the cassette film 12 and the address of the image on the roll microfilm 16. The microfilm scanner 14 is connected to a file controller 26 via a signal line 24.

An optical disk 28 and a floppy disk 30 are loaded into the file controller 26, and the image data read by the line sensor 20 is recorded on the optical disk 28, and the search report of the read image is sent. Optical disk 28 and floppy disk 30
It is now recorded to. The file controller 26 also includes a keyboard 32 and a CRT display 3.
4 is connected, and the operator operates the keyboard 32 in accordance with the instructions displayed on the CRT display 34 to supply the file controller 26 with search information for an image to be converted into a file.

Next, based on FIG.
The configuration of is explained in detail.

The rolled microfilm 16 is wound onto a supply reel 38 by driving a motor 36 and onto a take-up reel 42 by driving a motor 40. The rotation angle of the take-up reel 42 is detected by a pulse generator 44.

Here, as shown in FIG. 5, roll microfilm 1
6, at the same time as the document is photographed, page blip marks 1 and 2 are exposed on the lower edge corresponding to each frame 100, and file blip marks 104 indicating blocks of related frames are exposed on the upper edge. Ru. The address of piece 100 is
It is detected by sequentially counting the page blip mark 102 and the file blip mark 1.4.

The page blip mark 102 and file blip mark 104 are detected by a blip mark sensor 46 shown in FIG.

The image at the reading position of the roll microfilm 16 is
Light from light source 48 passes through condenser lens 50, roll microfilm 16, and imaging lens 52 and is imaged onto screen 18. A mirror 56 that rotates around a shaft 54 is disposed at the imaging lens 520, and a second
In the state shown in the figure, light from the light source 48 is reflected by the mirror 56 and passes through the imaging lens 58, and an image on the roll microfilm 16 is projected onto the line sensor 20. The line sensor 20 is sub-scanned by horizontally moving on this projection plane by a sub-scanning mechanism 62.

The sub-scanning mechanism 62 is driven by a motor 64.

Further, an automatic exposure sensor 65 is disposed toward the optical path of the projection light, and detects the amount of light transmitted through the film. This detected amount of light is used to change the amount of light by adjusting a light amount diaphragm mechanism (not shown) or adjusting the lamp voltage of the light source 48.

The detection signal of the automatic exposure sensor 65 is supplied to the input port 8 of the microcomputer 66 via the A/D converter 80. The microcomputer 66 is configured in a known manner, including an input port 8, a CPU 70, a ROM 72, a RAM 74, and an output port 6. From the output port 6, rotation control signals for the motors 36, 40, and 64 are sent to a drive circuit 78. In response, the drive circuit 78 outputs a drive current to the motors 36, 40, and 64 to rotate them.

The line sensor 20 is composed of, for example, a CCD, and is main-scanned by a transfer pulse from a main-scanning/reading circuit 82, and charges proportional to the amount of light received by the elements of the line sensor 20 are sequentially supplied to the main-scanning/reading circuit 82. This is converted into a voltage and supplied to the A/D converter 84. A/D
The signal converted into a digital value by the converter 84 is supplied to a binarization circuit 86 composed of a digital comparator, where it is compared with a threshold value supplied from the microcomputer 66 and converted into a value of 1 or 0. and line buffer 8
1 bit at a time. When switching the resolution, two lines of data are stored in the line buffer 88.
When the data is supplied to the resolution switching circuit 90, the resolution is switched from 16 dots/fi to 8 dots/n in response to a switching signal from the microcomputer 66. 2. The converted data is transferred to interface 9.
2 to the file controller 26.

Further, control signals and data are transferred between the file controller 26 and the microcomputer 66 via the interface 94.

The floppy disk 22 is loaded into a floppy disk driver 96, and the search information recorded on the floppy disk 22 is read by the microcomputer 66.

Next, the software configuration of the microcomputer 66 and the file controller 26 will be explained based on FIGS. 3 and 4.

A flowchart is shown in Figure 3, and Figure 4 (A
) shows a part of the search information table recorded on the floppy disk 22, and FIG. 4(B) shows a part of the search information table D recorded on the optical disk 28 and the floppy disk 30. It is shown. In addition, the fourth
In the figure, keywords as search information are shown in a simplified manner for convenience of explanation.

In step 200, the operator operates the keyboard 32 to input a keyword of the text (conversion text) for which the microfilm file is to be converted into an optical disk file. To simplify the explanation, this keyword will be referred to as A.

If the process end key is not operated in step 200,
Proceeding to steps 202 and 204, the keyword A and the keyword search command are supplied from the file controller 26 to the microfilm scanner 14. Based on this, the microfilm scanner 14 reads the search information from the floppy disk 22 and picks up search information having keywords including this keyword A. Fourth
In the example shown in Figure (A), search information having keywords PA, QA, and RA is picked up. Each keyword is
It is associated with the roll number of the cassette film 12 and the start address of the document on the roll microfilm 16. Each piece of search information consists of these keywords, the volume number, the start address of the document on the roll microfilm 16, the number of pages of the document, and the size of the document on which the image on the roll microfilm 16 is based.

Here, a document is, for example, a set of images separated by file blip marks 104 shown in FIG. 4, and the document address is obtained by counting the file blip marks 104. The pages within this document are obtained by counting page blip marks 102 from the beginning of the document.

Next, in step 206, the picked up search information and display command are supplied from the microcomputer 66 to the file controller 26. Based on this, the file controller 26 displays these search information on the CRT display 34. The operator confirms this and operates the keyboard 32 to select a keyword for file conversion. In this example, it is assumed that all of the displayed keywords PA, QA, and RA have been selected.

The file controller 26 supplies the selected search information and the search command to the microfilm scanner 14. Next, in step 210, the CPLI 70 sends the microfilm scanner 14 the volume number 03 that constitutes the first search information among these search information. Compare the roll numbers of the cassette film 12 already loaded in the microfilm scanner 14. If they are not the same number, proceed to step 212, and return the cassette film 12 loaded in the microfilm scanner 14 into the auto stocker 10. , 3rd j? for auto stocker 10? ! 5 and supplies a command to take out the cassette film 12. Based on this, the auto stocker lO
2 and load it into the microfilm scanner 14.

Next, in step 214, the file blip marks 104 are counted by the blip mark sensor 46 while the motor 40 is driven to wind the roll microfilm 16 onto the winding wheel 42. When the count value reaches 5, the motor 40 is stopped so that the first image of document address 5 is at the reading position.Then, in step 216, the image at this reading position is projected onto the screen 18. Next, in step 218, the operator confirms this image, operates the keyboard 32, and inputs reading information necessary for reading this image with the line sensor 20. This read information includes the following:

(1) Reading Size Depending on whether the document before being photographed on the microfilm is, for example, A4 or A3, the image on the microfilm will be vertically long or horizontally long.

The range to be read by the line sensor 20 when converting to an optical disk file is determined by this reading size.

In this embodiment, since the reading size is known from the document size (see FIG. 4) constituting the search information, there is no need for the operator to input the reading size.

(2) Reading resolution This is used to set the resolution switching circuit 90 (FIG. 2) to switch to, for example, 8 dots/dragon or 16 dots/l.

(3) Black and White Determination Threshold This is used to set a threshold for the binarization circuit 86 (FIG. 2) to determine whether pixel data is white or black.

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. Enter the threshold value when in manual mode.

Note that the above example is for binarization, but if you want to convert the read image into halftones, you can set modes such as auto, lock, and manual as above, and in manual mode, you can also convert the original image (original image). The setting of the stepwise judgment level of light and dark according to the shading of the image is also input.

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

The range specification mode for specifying the reading range includes a trimming mode for reading the set range and a masking mode for reading outside the set range, and the user selects either one 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 the white and black reversed (negative).

Next, in step 220, the content of the read information input in step 218 is checked. This input error check includes the following:

(1) Black and White Judgment Threshold Setting Error Check Is the appropriate range of this threshold set in advance in ROM? 2 and set in step 218 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.

(2) Reading range specification error check This determines the maximum readable range of a frame image from the document size shown in FIG. 4(A), and determines whether the reading range input in step 218 is included in this maximum range. Check.

Next, in step 222, it is determined whether or not there is an input error, and if there is an input error, in step 224, the CRT display 3
4 displays the details of the input error.

Then, the process returns to step 218 and the corresponding reading information is input again. If there is no input error, in step 226 the mirror 56 is rotated to project an image onto the line sensor 20, the motor 64 is driven to read image data based on the above read information, and this is sent to the file controller 26 along with a recording command. supply. Based on this, the file controller 26 records this image data onto the optical disc 28.

When the recording of image data is completed, search information as shown in FIG. 4(B) is recorded on the optical disk 28 and floppy disk 30. This search information is for searching images recorded on the optical disc 28, and consists of a keyword and the address of the document on the optical disc. The reason why the search information is recorded on the floppy disk 30 is to enable high-speed searching, and the reason why the search information is also recorded on the optical disk 28 is because the floppy disk 30 is not used or the information recorded on the floppy disk 30 is This is to recreate the search information on a new floppy disk 30 if the search information is destroyed.

Next, in step 228, since the document file conversion for the keywords QA and RA has not been completed, a negative determination is made and the process returns to step 210.

By repeating the processing of steps 210 to 226 above, documents regarding the keywords QA and RA are stored on the optical disc 2.
Recorded in 8. The document with keyword RA is recorded on a different volume of cassette film 12 from the volume on which the document with keyword QA is recorded, so step 2 is performed.
A negative determination is made in step 10, and the cassette film 12 is replaced.

Since the file controller 26 is equipped with a buffer memory and the image data supplied from the interface 92 is temporarily stored, the processing from step 210 to step 228 and the processing in which the file controller 26 records the image data onto the optical disk 28 are done in parallel.

According to this embodiment, the operator does not have to operate the keyboard 32 to directly input the address of the document on the roll microfilm 16, which makes it possible to prevent input errors and to input related images without omitting them. Moreover, since multiple documents can be specified using specific keywords, input operations are simplified and file conversion can be performed quickly.

Note that the present invention may be configured without the auto stocker 10.

In the embodiment, a floppy disk is used as an example of a recording medium for search information, but other recording media such as a hard disk may be used depending on its capacity.

Further, in the above embodiment, the input means for inputting the search information B is the keyboard 32, but the search information B may be recorded in advance on a floppy disk or the like using a personal computer or the like, and then read by the file controller 26. It's okay.

Furthermore, part or all of the above read information may be added to the search information A recorded on the search information recording medium. Regarding the read information, we have shown an example of inputting and checking it each time, but if the properties are the same, such as microfilms such as patent publications, it is possible to create it together with the search information B previously created. , input work is simplified and efficiency is improved.

〔Effect of the invention〕

In the image processing apparatus according to the present invention, when the search information B is input, the search information including the search information B is searched from the search information fgA recorded in advance on the search information recording medium, and the search information An image on the analog recording medium at an address corresponding to the information is moved to a reading position, the image is read by an image sensor, and is recorded on the digital recording medium together with the retrieved information. Therefore, there is no need to directly input detailed addresses of images on analog recording media, and there is no need to input search information for searching for images on digital recording media, which simplifies the input process. Therefore, there is an excellent effect that an image on an analog recording medium can be quickly recorded on a digital recording medium.

In addition, since all you have to do is input the search information that corresponds to the image, there is no need to accidentally specify the address of an image on an analog recording medium, and moreover, it is possible to record all images to be converted into a file on a digital recording medium. There is also a great effect of being able to do it.

Furthermore, with regard to reading information, for materials with uniform patterns and properties, such as microfilm in patent publications, by setting it at the beginning, you can eliminate the need to input it each time, which has the effect of further improving the efficiency of conversion recording. There is also.
