Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image modification method for modifying image elements such as color 9 positions of an image in an image display device that displays various images such as characters and figures.

Conventionally, image display devices that display various images such as characters and graphics have been divided into a display device (1) using a cathode ray tube, a keyboard (2) for inputting information on characters and graphics, and a keyboard (2) as shown in Figure 1. Therefore, it is often configured.

However, in such an image display device, when making corrections such as erasure, two color changes, one position movement, etc. to a part of the image displayed on the display device (1), conventionally, the force on the screen - Since a new image element is input from the keyboard (2) after moving the crane symbol display to the relevant part, it has the disadvantage that correction operations are troublesome.

The present invention has been made to solve these drawbacks, and its purpose is to provide an image modification method that can easily modify image elements such as color 9 position, including erasing the image. .

To this end, the present invention provides a coordinate input means for inputting the display area of the image to be corrected in two-dimensional plane coordinates, and after specifying the display area of the image to be corrected, the area is clearly indicated by flashing, high brightness, border display, etc. After that, the image element of the image in the area is modified by an operation corresponding to the content of modification.

The present invention will be explained below based on Examples.

FIG. 2 is a block diagram showing an embodiment of the present invention, and (3
) is a tablet that outputs a coordinate signal of a two-dimensional surface corresponding to the pressed point when the surface is pressed with an indicator pen (4), and the coordinate signal is used to specify the cursor signal display position on the display device (1). Used for signals.

In this configuration, when moving the image of an arbitrary rectangular area on the display screen to another position, the coordinate P1 of the upper left end and the coordinate P2 of the lower right end of the rectangular area are specified as shown in FIG. Specify by pen (4). Then, the cursor symbol display on the display device (1) first moves to the position corresponding to the coordinate P1, and then moves to the position corresponding to the coordinate P2.
Move to the position corresponding to . As a result, a rectangular area surrounded by diagonal lines in FIG. 3 is designated, and this area is clearly indicated by flashing, high brightness, or border display. At this time,
If there is an error in the area specification, perform the area specification operation again.
.

However, if there is no error in specifying the area, use the pointing pen (4) to specify the destination of the image within the rectangular area. This destination specification is possible because the size of the source area is known.
You only need to provide the coordinates of the upper left corner of the destination area.

When the destination area is designated, this area is made clear by blinking or other means in the same way as the source area.

Therefore, if the destination area is correct, an image movement command is given to the display device (1,) by appropriate means, and the image displayed in the source area is moved and displayed in the destination area.

Therefore, in this embodiment, since only the source area and destination area of the image are specified, the position of the image can be corrected extremely easily.

Such operations are similarly performed for erasing images, changing one color, reversing brightness, and the like.

Note that the coordinates may be specified not by the tablet but by other means such as a light pen or a keyboard.

As described above, according to the present invention, after specifying the correction area of an image element by coordinates, an instruction corresponding to the correction content is given. Therefore, it is possible to change or correct an image element extremely easily, and it is possible to perform graphic processing. If applied to a device, etc., it is possible to easily perform image decomposition and compositing.

Claims (1)

[Claims] An image display device for displaying images such as characters or figures is provided with a coordinate input means for giving a display area of an image to be corrected of an image element in two-dimensional plane coordinates, and the display area of the image to be corrected is specified by this coordinate input means. An image correction method for an image display device, characterized in that the area is then made clear and image elements of an image displayed in the display area are corrected.
