Abstract:
A burn-in correction system including a display unit equipped with a display panel displaying an image according to input image data, and an imaging unit acquiring imaged image data by imaging the display panel from a viewing side, the system correcting burn-in on the display panel. The system further includes: a lighting unit lighting each pixel constituting the display panel in order under a preset lighting condition; a calculation unit calculating a difference value between luminance of the imaged image data of each pixel lighted by the lighting unit, the imaged image data acquired by imaging each lighted pixel with the imaging unit, and luminance preset in the lighting condition; and a correction unit correcting luminance of each pixel based on the input image data, the correcting performed based on the difference value calculated by the calculation unit.
