Abstract

PURPOSE:To automatically secure the relation with the original data by adding the information on the relation with the registered picture data (original data) to the correction data. CONSTITUTION:When pictures are registered, the picture data is read into an image memory 21 from a scanner 4 via a system bus 9 and then stored in an optical disk 7. In this case, a retrieving key word is supplied to the picture data, from a keyboard 5 for correspondence. The tracks, sectors, the number of working sectors, the discrimination between the original data or the modifying data, a pointer into a retrieving file 23 to the modifying data with the original data if discriminated, etc., stored in the disk 7 are added to the file 23 as information. Thus it is possible to secure automatically the relation with the original data.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for inputting corrected image data.

[Prior art] When registered image data (hereinafter referred to as original data) is outputted using a printer and is modified by handwriting etc., it is input again to create modified image data (hereinafter referred to as modified data). In the example, when setting the paper when inputting modify data, misalignment and tilting tended to occur. Furthermore, it is difficult to correlate which image data the modify data is a modified image of.

[Purpose] The present invention was made in view of the above points, and an object of the present invention is to create a relationship with the original data by adding information that distinguishes the original data when outputting the original data. It is.

[Example] FIG. 2 shows an example of the present invention. In the diagram, 1
The microprocessor 2 that controls the entire system is a main memory that serves as an input/output buffer for inputting programs and scanners and outputting to the printer according to the control procedures shown in the flowcharts of FIGS. 4 and 6. It has an image memory (21), a work area (22), and a search file (23).

3 is a display device that displays images. 4 is a scanner that inputs images. 5 is the keyboard. 6 is a disk device in which software etc. for controlling this system are stored. 7 is an optical disk device for storing image data. 8
is a printer for outputting image data.

IO is a compression/expansion circuit that compresses and expands images. Each of these components is electrically connected to 1 via 9 system buses.

The operation of the above configuration will be explained in detail below.

■Image registration The image data (Fig. 1a) is read from the scanner 4 to the image memory 21 via the system bus 9 (S3), and then stored on the optical disk 7; A search keyword is entered into the data using the keyboard and made to correspond to the search keyword (S3-1). The search file has a format as shown in Figure 3, and includes the tracks and sectors stored on the optical disk, the number of sectors used, and whether it is original data or modified data, and if it is original data, a pointer to the modified data in the search file, etc. is added as information. The image data to be stored on the optical disk is 1
0 compression/expansion circuit (S4) to increase the storage rate.

■Output of registered images Enter a search keyword from the keyboard to determine which image data to output (S8). A match is found from the search file (S9), and image data is read from the corresponding track and sector of the optical disc into the image memory (S10, to-1). When outputting to a printer, add a mark like the one shown in Figure 1 so that it can be input later as correction data and associated with this data (
Sll.

12). The cross marks 101 at the four corners of the figure are marks used to correct the misalignment or slanting of paper when it is read by a scanner, which prevents it from being set accurately. Further, a bar code 100 in the figure is an encoded keyword of this data, indicating that it is modified data.

■ Input of corrected image data The corrected image data (C in Figure 1) is read from the scanner into the image memory 21 as in the image registration of ■ (S14).
). Then, this data is moved and rotated in the memory so that the marks at the four corners are in the correct positions (S15).

Store it on an optical disk as shown in ■ image registration, and (S
20) Register the keyword and other information in the search file (S20.21).The keyword at this time is obtained from the barcode (S16). Next, a search file matching this keyword is found from the search file (S17). It then chains its modified data pointer to the address of the block in the search file that contains the modified data information.

In the above, a barcode was used to associate the original data with the modified data, but if the barcode is attached directly to the original data as a keyword and read from a scanner and registered with that keyword, the need to enter the keyword from the keyboard can be omitted.

However, it was necessary to have two pieces of raw data: original data and modified data. In the first place, image data requires a large amount of storage capacity, and having two pieces of data separately leads to deterioration of the processing capacity of the image processing device. Hereinafter, a solution to this drawback will be explained with reference to FIG. 6.

Image registration and output of registered images are the same as those described in (1) and (2) above, so the explanation will be omitted.

Note that processing chips that are the same as those in the flowchart of FIG. 4 are given the same reference numerals.

■ Input of corrected image data The corrected image data is read from the scanner into the image memory 21 as in the input of corrected image data in ■ (S14).
). Based on the barcode 100, it is determined which original data this data is modified data from and the keyword of the original data (S16).

A file matching the keyword is found from the search file (S17). The original data is read from the track/sector of the optical disk pointed to by the work area while being expanded using the compression/expansion circuit (S17-1.17-2)
.

Then, the difference between the modified data in the image memory and the modified data is taken as modified data (S17-3). This results in a considerably reduced amount of information as shown in Figure 5a. Secure an empty block from the search file to store the modify data (31B), and delete barcodes and marks from the image memory data5.
19), then compress the modified data using a compression/decompression circuit 519-1) and store it on the optical disk 520
), information such as the track sector is set in the modified data block 521), and its address is set in the modified data pointer of the original data block (S21-1), thus completing the input of modified image data.

■Output of corrected image data A keyword is input from the keyboard to determine which image to output (S22). A match is found from the search file (S23).

The image data is decompressed from the corresponding track sector of the optical disk using a compression/decompression circuit and read out to the image memory (S24-25). The original data has now been extracted. When the modified data pointer of the search file is not 0, modified data exists, and the modified data is decompressed and read out from the optical disk to the work area using the compression/decompression circuit in the track sector of the block at the address pointed to by the pointer (S26~ 29) and the original data in the image area are logically summed and displayed on the CRT (S30). (If you take the logical sum of FIG. 1a and FIG. 5a, you will get FIG. 5.) The operator judges whether the displayed data is the desired corrected data and issues an instruction from the keyboard (S31-32).

If it is the desired correction data, this data is output from the printer (S34). If this is not the case, since the modified data pointers are chained, the pointer is followed and the next modified data is sequentially displayed in the same operation to obtain the desired modified data (S33).

In this way, images can be stored efficiently by making the corrected data different from the original data.

Further, the modified data can have a plurality of modified data from one original data using a modified data pointer.

Therefore, it is possible to synthesize original data and multiple pieces of modified data.

[Effect of the invention] As explained above, by attaching information indicating the relationship with the original data to the corrected data, it is now possible to automatically attach the relationship with the original data when this data is input later. .
