Patent ID: 8228351

Claim:
An image display apparatus comprising: a light source; a spatial light modulation element modulating light from the light source based on a video signal; light quantity adjustment means for adjusting light quantity of light from the light source based on luminance information represented by the video signal; image correction means for correcting the video signal so that luminance level of the video signal increases as the light quantity is adjusted to decrease by the light quantity adjustment means, and supplying a corrected video signal to the spatial light modulation element; and re-adjustment means for performing re-adjustment such that, of a light quantity adjustment target and a luminance level correction target, at least the luminance level correction target is re-adjusted to a value in an opposite direction from a correction direction by the image correction means, in a case that the display light output, representing a luminance of the light modulated by the spatial modulation element, is higher than a predetermined luminance level, where the luminance level correction target represents a correction target value in the luminance level of the video signal, employed by the image correction means, and the light quantity adjustment target represents a adjustment target value in the light quantity, employed by the light quantity adjustment means, wherein, in the case that the light quantity adjustment target is higher than a predetermined light quantity threshold value, the re-adjustment means re-adjusts the light quantity adjustment target to a higher value, and wherein the threshold is adjustable in accordance with an image pattern based on the video signal.
