Abstract

<P>PROBLEM TO BE SOLVED: To efficiently form, preserve and reuse a color pallet of a computer by a mixed color. <P>SOLUTION: A basic color area, a mixed color work area and a mixed color preserving area are prepared for an output part (a display part) of the computer. A basic color of white, yellow, green, blue, red and black is allocated to the basic color area. A Venn diagram of a set figure superposed by respectively dislocating three circles is allocated to the mixed color work area. A color is selected from the basic color area or the mixed color preserving area, and the circle of the mixed color work area is designated, and a mixed color is formed in response to overlapping of the Venn diagram. The mixed color is provided by dividing by 2 by respectively adding two or dividing by 3 by adding three on a primary color component of RGB. The mixed color is copied on the mixed color preserving area from the mixed color work area, and can be written out to a data preserving part from the mixed color preserving area. Color data can be read in from the mixed color preserving area from the data preserving part. This invention depends on the data structure and a program. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention relates to a computer image display program, and more particularly to generation of a color palette.

There is a color generation means by mixing on the palette. In this method, two colors are designated as the original colors for color mixture, and the color mixture operation is repeated. (For example, JP-A-8-315104)
JP-A-8-315104

Efficiently create, store, and reuse computer color palettes by mixing colors.

A basic color area, a mixed color work area, and a mixed color storage area are prepared in the output section (display section) of the computer.

Assign basic colors of white, yellow, green, blue, red and black to the basic color area.

A Venn diagram of a collective diagram, in which three circles are shifted and overlaid on the mixed color work area, is assigned.
A color is selected from the basic color area or the mixed color storage area, a circle in the mixed color work area is designated, and a mixed color is generated in accordance with the overlapping of Venn diagrams. The color mixture is obtained by adding 2 and dividing by 2 or 3 and dividing by 3 for the three primary color components of RGB.

The mixed color is copied from the mixed color work area to the mixed color storage area, and can be written from the mixed color storage area to the data storage unit. Color data can be read from the data storage unit in the mixed color storage area.

According to the above data structure and program.

Computer color palettes can be efficiently generated, stored, and reused through color mixing.

A rectangular area is prepared as a basic color area. White, yellow, green, blue, red, and black are assigned as basic colors in order from the left.

The usage state of the Venn diagram in the mixed color work area is managed for each circle. The Venn diagram is initially displayed, and all the usage states are unused for the circle.

As a mixed color storage area, 6 columns * 8 rows = 48 rectangular areas are prepared. The initial rectangular area color is white.

Specify the basic color area or mixed color storage area with the operation pointer of the computer's input unit, and perform color drawing. The color is discharged by specifying the inside of the circle composing the Venn diagram with a pointer. One circle with the shortest distance between the pointer position and the center coordinate of the circle is selected. The circle is in use.

The mixed color is generated by adding 2 and dividing by 2 or adding 3 and dividing by 3 for the three primary color components of RGB. Paint basic colors or mixed colors to overlap each area of the Venn diagram.

The mixed colors generated by the circle in use of the circles constituting the Venn diagram are collectively copied from the mixed color work area to the mixed color storage area.

Allows editing (deletion, transfer) of the mixed color storage area.

Overwrite and insert are prepared as copy and delete editing modes. The edit position of the mixed color storage area can be specified.

A function to write and read the contents of the mixed color storage area is prepared.

Claims (1)

A basic color area, a mixed color work area, and a mixed color storage area are prepared in the output section (display section) of the computer. Assign basic colors of white, yellow, green, blue, red and black to the basic color area. A Venn diagram of a collective diagram, in which three circles are shifted and overlaid on the mixed color work area, is assigned. A color is selected from the basic color area or the mixed color storage area, the circle of the mixed color work area is designated, and the inner color of the circle is set.
For the three primary color components of RGB, in accordance with the overlap of the Venn diagrams, two are added and divided by 2, or three are added and divided by 3, thereby generating a mixed color. The mixed color is copied from the mixed color work area to the mixed color storage area, and can be written from the mixed color storage area to the data storage unit. Color data can be read from the data storage unit in the mixed color storage area.
The above data structure and program.
