Abstract:
1. An image processing apparatus that performs display control of an image displayed on a display unit, comprising: a first control circuit to perform sticking prevention for controlling image data of a frame or a display timing control signal corresponding to the image data so as to display each pixel forming the image with different brightness at given intervals, a second control circuit to perform sticking prevention for controlling the image data or the display timing control signal by different control from that by the first control circuit so as to display each pixel forming the image with different brightness at given intervals, an interval register set with control data corresponding to an interval time between first control start timing by the first control circuit and second control start timing by the second control circuit, after the control of the image data or the display timing control signal is started by the first control circuit, and the interval time set in the interval register has elapsed, the first control circuit and the second control circuit control image data of an identical frame or a display timing control signal corresponding to the image data, the first control circuit and the second control circuit control image data of an identical frame or a display timing control signal corresponding to the image data by switching mode at predetermined intervals; wherein the first control circuit and the second control circuit control the image data or the display timing control signal so as to display each pixel forming the image with different brightness at given intervals in at least one mode among a first mode of shifting an original display image by an amount corresponding to one dot after a first interval time has elapsed, a second mode of switching between interlace scanning and progressive scanning each time a second interval time has elapsed, a third mode of lowering a frame rate for each dot and a fourth mode of thinning out an image display for each given frame, and wherein a first mode sequentially repeats, at every lapse of a given period of time, a first shift of shifting an original display image by an amount corresponding to one scanning line in a first vertical scanning direction of a screen of the display panel, a second shift of shifting the original display image by an amount corresponding to one dot in a first horizontal scanning direction of the screen of the display panel, a third shift of shifting the original display image by an amount corresponding to one scanning line in the opposite direction to the first vertical scanning direction of the screen of the display panel, and a fourth shift of shifting the original display image by an amount corresponding to one dot in the opposite direction to the first horizontal scanning direction of the screen of the display panel.
