This invention relates to a pseudo-arbitrary transfer area designation method for images that can perform.

In the figure, 1 is an input device such as a keyboard with arrow keys for specifying coordinates or a pointing device for specifying an area such as a mouse, 2 is a monitor that displays an image, and 3 is an input device that is a pointing device for specifying an area such as a keyboard with arrow keys for specifying coordinates. 4 is a coordinate input mechanism unit that imports specified coordinates into the system; 4 is an arbitrary area transfer mechanism unit that divides the shape of an arbitrary area line by line and transfers it;
5 indicates the start point (X18.Y13) and end point (XIE) of the transfer source on the image memory, as shown in FIG.

A rectangular area transfer mechanism unit for transferring the source rectangular area to the transfer destination by giving the transfer destination start point (X2S, Y28), 6 is the image memory that stores the image, and T is this image memory 6 is an image display mechanism section that controls the display of images on the monitor 2; 8 is the coordinate input mechanism section 3. Arbitrary area transfer mechanism section 4. Rectangular area transfer mechanism section 5. This is a system control mechanism section that is composed of an image memory 6 and an image display mechanism section 1, controls the entire system, and includes arbitrary area designation processing.

Next, the operation of the image pseudo-arbitrary transfer area designation system having the above configuration will be explained. First, the image on the image memory 6 is displayed on the monitor 2 by the image display mechanism section 7. Then, using the input device 2, an arbitrary area is specified on the image displayed on the monitor 2 using a free curve or a polygon. When this arbitrary area is specified, the shape of the arbitrary area is specified to the arbitrary area transfer mechanism section 4, and the specified dead area can be transferred using the arbitrary area transfer mechanism section 4. As a method for specifying this arbitrary area, it has been proposed to specify an arbitrary area using a prisoner-free curve, or to specify an arbitrary area using a polygon.

[Problem to be solved by the invention]

In the above-described conventional image arbitrary transfer area designation method, especially when polygons are used as the arbitrary area designation method, complex calculations are required to supplement the coordinates between designated points. Furthermore, when specifying an arbitrary region, special logic is required to specify the region surrounded by a closed curve.

In order to transfer an arbitrary area, a special mechanism such as a function for transferring an arbitrary area on one line is required. In this way, it is necessary to have a transfer mechanism for arbitrary areas configured by functions, and it is also necessary to perform complex processing such as complex coordinate interpolation, determination of closed curves, and transfer of a special line, and it takes a large amount of processing time. There are disadvantages such as requiring

[Means for Solving the Problems] The pseudo-arbitrary image transfer area designation method according to the present invention is a pseudo-arbitrary image transfer area designation method that specifies a plurality of rectangular areas in order to designate an arbitrary area on an image displayed by an image display mechanism. The system control unit is provided with an arbitrary transfer area designation processing means and a pseudo-arbitrary area transfer processing means for transferring each specified rectangular area, and it is possible to transfer pseudo-arbitrary areas by transferring each rectangular area! It is something to do.

[Effect]

This invention can perform pseudo-arbitrary area transfer by specifying a plurality of rectangular areas.

〔Example〕

FIG. 1 is a system configuration diagram showing an embodiment of a pseudo-arbitrary image transfer area designation method according to the present invention. In the figure, 9 is a rectangular area transfer mechanism for transferring a rectangular area on the image memory 6, and 10 is the coordinate input mechanism section 3.
．． Image memory 6 is a system control mechanism section that is composed of an image display mechanism section 7 and a rectangular area transfer mechanism section 9, has a pseudo-arbitrary transfer area designation processing function and a pseudo-arbitrary area transfer processing function, and controls the entire system.

Note that the above pseudo-arbitrary transfer area designation processing function sets the start point and end point of the transfer source to the first rectangle 111, as shown in FIG.
- is given for each third rectangle 11e, and the transfer destination specifies where to transfer the area that includes all of the first to third rectangles 111 to 11e of the transfer source. As shown in the third factor, a plurality of rectangular areas can be specified on the image displayed above using the input device 1 such as a mouse. Further, the pseudo-arbitrary area transfer processing function transfers each rectangular area by using the rectangular area transfer mechanism section 9 for a plurality of specified rectangular areas as shown in FIG. P transfer is performed by providing a transfer source start point and end point and a transfer destination start point for each area.

Next, the operation of the image pseudo-arbitrary transfer area designation method with the above configuration will be described. First, image memory 6
Display the image above as image 1! ! It is displayed on the monitor 2 by the structure T. Then, using the human power device 1, as shown in FIG. 2 on the image displayed on this monitor 2,
The starting point and ending point of the transfer source are given for each of the rectangles 118 to 3rd rectangle 11C. Then, when the transfer destination specifies where to transfer the area including all of the first rectangle 11a to the third rectangle 11e of the transfer source, the rectangular area transfer mechanism unit 9 processes it by the pseudo-arbitrary transfer area specification processing function. By providing the starting point and ending point of the transfer source and the starting point of the transfer destination for each rectangular area from the first rectangle 11& to the third rectangle 11C, it is possible to perform one-row transfer. At the time of transfer, various types of synthesis can be performed by performing logical synthesis (OR, AND, EXOR, etc.) with the image at the transfer destination, and the resulting image can be transferred to a designated area.

Note that it is of course possible to perform arbitrary rate transfer by allowing the rate to be specified in the transfer vA. In addition, the method for specifying a rectangular area will be explained assuming that each rectangular area is in contact with each other. t may be a closed area with holes as shown in Figure 4 (1), or it may be a closed area with holes as shown in Figure 4 (b). Of course, it is also possible to specify areas divided into several parts.

〔Effect of the invention〕

As explained in detail above, according to the pseudo-arbitrary image transfer area designation method according to the present invention, since designation is performed using multiple rectangular areas, it is only necessary to enclose the portion that is difficult to transfer with a rectangle. Since there is no need to be aware of the area (the area where the start point and end point are connected), it is possible to transfer areas with holes, and there are effects such as the ability to realize pseudo-arbitrary area transfer.
