Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image processing method for editing and processing digitized multiplication image signals.

In the prior art, electrical circuits are used to individually perform each edit, such as inverting the image signal stored in memory or completely compositing two images. Such prior art has limited processing power,
For example, to externally shift an il image by 90 degrees, or to create a plane-symmetrical mirror image, extremely complex circuitry is required.

SUMMARY OF THE INVENTION An object of the present invention is to provide an image processing method that allows images to be processed in any editing manner.

FIG. 1 is a block diagram of one embodiment of the present invention. This image processing method basically includes an image reading device 1, an editing device 2, and a printer 3 using a laser or the like to print the edited image. It is equipped with a magnetic disk 4 used for storage, a display 5 housed in a cathode ray tube, etc., and a key manual device 6.

In the reading device 1, in order to read a document drawn on the document 7 or the like and store it in the storage area 8A or 8B for one page of the image memory 8 provided in the editing device 2, first, A microprocessor 9 providing a read command signal from an interface 10 to a controller 12 via an ink face 11. In response to this fLK, the controller 12 turns on the drive circuit 13, and uses the charge storage element 14 to read the document by one scanning line.

A condensing lens 15 and the like are provided in association with the charge storage element 14. Imaged by charge storage element 14vC
The image signal for one scanning line is amplified by the amplifier circuit 16, binarized into black and white by the binarization circuit 17, and digitized.The signal is stored in the panzer memory 18VC. Image No. 18 stored in the panzer memory 18 for this -scanning line is stored from the ink face 11 to the corresponding position in the storage area 8A of the image memory 8 via the interface IUf. 4 like this
Repeat work 01 and store one page of original number 147 in storage area 8A.

In order to print all the stored contents of the store area 8A with the printer 3, the microprocessor 9 uses the interface l9.
A print command is given to the printer 3 via fc. This causes the 1-image signal 11 stored in the storage area 8A to be transferred from the microprocessor 9 to the ink face 19.
The image is then sent to the printer 3, where the image for one member is printed.

The image stored in the storage area 8A of the image memory 8 can be printed by the printer 3 after being reversed in black and white. The store state of the store area 8A is as shown in FIG. 2, and it is assumed that the editing area 20 in the store @ area 8A is to be inverted in black and white. The editing area 20 is
It is a square or rectangular quadrilateral whose vertices are referenced e, f.

They are indicated by g and h, respectively.

Referring to FIG. 3, in step n1, the coordinates (XSI, YSI) of the vertex e of the inversion area 20 are determined, and the distance XL between the vertices e and h and the distance YL between the vertices e and f are specified. Then, the editing area 20 is determined. Such coordinate designation can be performed using the key manual +t6vC. The microprocessor 9 extracts a plurality of bits in parallel in the horizontal direction of the editing area 20 in step n2, inverts the data in step n3, and then returns the inverted data to its original position in step n4. One operation of steps n2 to n4 is performed by scanning in the horizontal direction, and the scanning is sequentially shifted in the vertical direction, thereby inverting all the image signals in the editing area 20. The thus inverted image signal in the store area 8A including the fcNM collection area 20 is printed by the printer 3.

As shown in Fig. 4, editing area 2 of 2-store head area 8A
The contents of 1 and the contents of the edit area 22 of the store area 8B are logically ORed, logically ANDed, or exclusive ORed EX-O.
Logic processing such as R is performed, and screens are synthesized based on the results of the logical processing and stored in the editing area 22. In order to perform such cutting, first, the editing area 21 on the source side of the store M area 8A is determined. For this purpose, in step n1 of FIG. 5, the coordinates (XSl
, 'YSI), the distance XL in the x75 direction and the distance YL in the Yi direction are determined. In step n2, the edit@area 22 as a destination is logically processed and stored.

Therefore, the microprocessor 9 collects the data in the editing area 21 in parallel bits, and in step n4, the data in the editing area 21
The data in is extracted in parallel bits, and then step n5
Now, logical processing is performed on the data taken out from the editing areas 21 and 22. This logical processing may be a logical sum OR, a logical AND AND, an exclusive OR EX-OR, or the like. In step n6, the calculated result is returned to the corresponding coordinate position in the storage area 8B and stored.

Specify the distance XL in the X direction and the distance YL in the Y direction.

In step n2, the information in the editing area 20 is read in parallel bits, and to erase the read data, it is set to logic "0", and to paint it black, it is set to logic fIAr1. In this way, the data for which the logic "0" and fc were set to the logic "1" are stored again at the corresponding position in one editing area 20.

As shown in FIG. 7, the data in the predetermined edit area 23 of the store area 8A is moved to another predetermined edit@area 24 in the same store area 8A C) and the data in the original edit area 23 is deleted. You can "#move". In addition, when the editing area 23 is transferred to the editing head 'jIA 24 as shown in FIG. 23 can be moved, and at this time, the data in the portion of the editing area 23 that does not overlap with the editing area 24 is erased.
