Claims

[Claims for Utility Model Registration] (1) A color control device that includes a frame buffer for storing pixel data and a color palette in which color data is arranged, and outputs color data corresponding to the values of the pixel data to a display. a color change requesting means; an arithmetic processing means for arithmetic processing the pixel data of the frame buffer and shifting it to another value in response to the color change request; and a copying means for writing the arithmetic result to the frame buffer. 1. A color control device for a day-play image, characterized in that it is provided with: (2) In a multi-window display device, a change in which the color data for each window is separated and arranged in separate tables on the color palette, and the color or gradation of each window is changed in the memory or auxiliary storage device. a control means for respectively storing color data and writing window pixel data from the memory to the frame buffer; and simultaneously with said writing;
1. A color control device for a display image, characterized in that a copying means is provided for reading changed color data of another window that has already been displayed from the memory and directly writing it into a table of the window. (3) In a multi-window display device, a control means for separating and arranging color data for each window in separate tables on a color palette and writing pixel data for each window from memory to a frame buffer; At the same time as writing, a calculation processing means reads the color data of the table of the window from the color palette and performs calculation processing on the color data, and a copying means writes the result of the calculation processing to the table of another window displayed before the window. A display image color control device comprising:
