ABSTRACT:
An image having a large contrast and excellent visibility to the viewer is displayed on an image display device used in the presence of light. A black-display characteristic specifying means generates a black-display characteristic specifying data indicating the brightness of the external light reflected from the surface of an image display means, which is obtained by operating an external-light brightness specifying bar to be displayed on the image display means. A black-approximated data calculating means calculates, based on the black-display characteristic specifying data, a black-approximated data related to at least one of luminance, chromaticity and tristimulus values in displaying black with the image display means. On receipt of an image data and the black-approximated data, a black correction means calculates a black-corrected image data, and displays an image on the image display means based on the black-corrected image data.
