PROBLEM TO BE SOLVED: To provide an image processing controller IC which has reduced peak of EMI noise as a whole by supplying clock signals of different phases to three color signal processing circuits, respectively, and eliminating overlap of each EMI noise generated at different timing on a time axis by the clock signals of different phases. SOLUTION: The image control IC for processing a color data for one pixel by dividing the data into a first to third color signals R, G, B has: a clock signal generating circuit 28 which receives a reference clock signal DCLK and outputs the first to third clock signalsϕ1 toϕ3 differing in phase from each other; a first color signal processing circuit 20 for processing the first color signal R using a first synchronizing circuit driven simultaneously by the clock signalϕ1; a second color signal processing circuit 22 for processing the second color signal G using a second synchronizing circuit driven simultaneously by the clock signalϕ2; and a third color signal processing circuit 24 for processing the third color signal B using a third synchronizing circuit driven simultaneously by the clock signalϕ3.
