ABSTRACT:
A gradation converting process is carried out on an image signal and in accordance with a predetermined gradation converting table, and a visible image, which is represented by an image signal having been obtained from the gradation converting process, is displayed on an image displaying device. In the gradation converting process, the amount of depletion of luminance of the image displaying device is detected, and the gradation converting table is corrected in accordance with the detected amount of depletion of luminance such that the depletion of luminance of the image displaying device may be compensated for. A visible image having good image quality is thereby displayed on the image displaying device regardless of depletion of luminance of the image displaying device.
