Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image processing method, which eliminates the need for expensive peripheral equipment by specifying the position of the peripheral area of the screen of an image display device, and allows easy operation and processing without the need to look at anything other than the screen. The purpose of this invention is to provide an image processing method that is highly efficient.

Generally, in an image processing system, an image such as a figure is displayed on the screen of an image display device such as a cathode ray tube (hereinafter referred to as "display"), and this image is processed such as deformation, erasure, color change, etc. by moving the cursor. The first operation is to specify the two-dimensional position above, and in addition to this, the operation to specify the movement trajectory of the cursor or the color to be displayed between the points specified by the cursor, and the color to display this trajectory. second operations, such as an operation for specifying a figure, an operation for moving the figure drawn above in the vertical or horizontal axis direction on the display, an operation for issuing a processing command to enlarge or reduce the figure; There is.

In conventional image processing systems, there is a method in which a light pen (not shown) is used on the display 1 shown in FIG. 1 to perform the first operation, and a keyboard 2 is provided and this operation is used to perform the second operation. In this case, a keyboard 2 is required, which is expensive, and a type of key operation different from that for two-dimensional position designation must be performed, resulting in a reduction in work efficiency.

In addition, an area such as a command table for specifying a second operation is provided in a part of the display 1, and a part of the area of the command table can be selectively specified while performing the first operation with a light pen. A method of performing various second operations may also be considered, but in this case, if a large area is allocated to the area on the display 1 where figures can be displayed, the area allocated to the command table will be relatively reduced, and the command items in the command table will be Second, such as selectively specifying
There is a drawback that work efficiency cannot be improved because the work of specifying the two-dimensional position becomes delicate due to the operation of the The first operation is performed by specifying the area 3a corresponding to the two-dimensional position, and the command table 3b for the second operation is pasted to the area outside the area 3a of the XY digitizer 3. In the method of selecting command items two-dimensionally with the stylus 4 to perform various second operations, the XY digitizer 3 is very expensive, and the operator 5 needs to use the display 1, the area 3a of the XY digitizer, and the command table 3b. The disadvantage was that it was necessary to look at the images alternately, which reduced work efficiency.
6 is a computer for performing image processing, and is connected to a display 1, a keyboard 2, and an XY digitizer 3 necessary for each method. The present invention eliminates the above-mentioned drawbacks and will now be described with reference to one embodiment thereof, with reference to FIGS.

FIG. 2 shows a block diagram of the image processing method according to the present invention. In the figure, numeral 7 denotes a two-dimensional position specifying device of limited movable range type, and for example, a pan pot 8 as shown in FIG. 3 is used. This is for freely moving the stick 9 back and forth, left and right, and correspondingly moving the cursor on the display 1. The two-dimensional position specifying signal output from the two-dimensional position specifying device 7 is supplied to the computer 10, where the cursor on the display 1 (consisting of the horizontal axis 1a and vertical axis 1b on the display 1 shown in the first figure, hereinafter 1 cursor 1a, 1bJ) is supplied to the display 1 and displayed as cursors 1a and 1b on the display 1. Here, the two-dimensional position specifying device 7 is a display 1 shown in FIG.
The outer peripheral area 11 can be virtually specified by surrounding the screen 1c.

This outer peripheral area 11 includes an upper left part 11a, an upper part 11b, an upper right part 11c, a left part 11d, a right part 11e, a lower left part 11f,
It is divided into a lower part 11g and a lower right part 11h. For example, the right part 11e has a pseudo function that displays various color palettes (hereinafter referred to as 1 palette) on the screen 1c in order to select the color of the figure drawn on the screen 1c. .Switch, upper part 11b
11g is a pseudo switch with a function of displaying a group of commands (hereinafter referred to as 1 menu, equivalent to the above-mentioned command table 3b) on the screen 1c in order to select commands such as drawing a straight line or coloring the inside of a closed curve; is a pseudo switch that adds and displays scales to the cursors 1a and 1b, the left part 11d is a pseudo switch that erases the above palette, menu, and scale from the screen 1c, and the other parts 11a, 11c, and 11
Similarly to the above, f and 11h are pseudo switches having various functions. Furthermore, when drawing a straight line, the outer portion 11 functions as a pseudo switch that separates the straight line. These pseudo switches move the screen 1c and cursors 1a, 1b by operating the pan pot 8, for example, cursor 1.
When the intersection point of a and 1b virtually enters the right portion 11e from the screen 1c, the palette is activated and displayed on the screen 1c. At this time, other operations such as push buttons are not particularly required. Here, as an example of image processing, a case will be described in which a straight line is drawn between points A, b and C, d on the screen 1c.

First, operate the cursors 1a and 1b using the pan pot 8 to specify the upper part 11b and display a menu on the screen 1c, place the intersection of the cursors 1a and 1b on the command to draw a straight line from the menu, and press the button. Press a button (not shown) to input the above command. Since this command requires specifying the color of the straight line, inputting this command automatically causes the menu to disappear and the palette to appear. Next, place the intersection of the cursors 1a and 1b on the desired color palette, press the button to select this color, and then designate the left part 11d to erase the palette. Next, place the intersection of cursors 1a and 1b on point a and press the push button (not shown), then place it on point b and press the push button to draw a straight line of the desired color between points Ab. . After this, move the cursors 1a and 1b to a position other than the upper part 11b in the outer peripheral area 11 (for example, specify the left part 11d), and press the button in order on the points C and d after dividing the straight line (Fig. ) to draw a straight line between points C and d. In this way, the first and second
All operations are performed using the pan/pot 8 and the only pushbutton (not shown), so the operator's line of sight is directed toward the display 1.
Image processing can be performed with extremely high efficiency without requiring separation from the camera. In the above embodiment, the outer peripheral area 11 is divided into 8 parts to form 8 pseudo switches, but if more functions are required, the functions can be transferred to the screen 1 as in the case where the upper part 11c is specified.
c and select the desired function from among them.

Note that the two-dimensional position specifying device 7 may be a ball controller other than the pan pot 8 shown in the third figure, an XY volume controller, etc., and is not limited to the above embodiment. As described above, the image processing method according to the present invention uses a two-dimensional position specifying device that can specify the two-dimensional position of the screen and the surrounding area adjacent to the screen as a processing command to specify the surrounding area, so that all operations can be performed easily. can be done using a two-dimensional positioning device and one pushbutton, thus eliminating the need for expensive peripheral equipment.
The operator can operate the image display device without taking his/her line of sight off the screen, the operation is simple, processing can be performed with high efficiency, and the desired image can be displayed over a large area of the entire screen. be.
