Method for varying initial value in gray scale modification |
摘要 |
An error diffusing circuit modifies input video data signals representative of the gray levels of 8-bit gradation to output video data signals representative of the gray levels of 6-bit gradation, and an initial value generator produces an initial value for each of the first video data signals on each line of a frame, wherein the initial value generator varies the initial value depending upon the combination of a frame number, a line number and the color so that any pattern is not unintentionally produced on the display panel.
