  • Patent number: 8754840
    Abstract: An image display apparatus includes: a light source; a spatial light modulation element modulating light from the light source based on a video signal; light quantity adjustment section adjusting the light quantity of light from the light source based on luminance information in the video signal; image correction section correcting luminance level of the video signal in accordance with light quantity adjustment by the light quantity adjustment section, and supplying a corrected video signal to the spatial light modulation element; and re-adjustment section performing re-adjustment such that a light quantity adjustment target is re-adjusted to a lower value, in a case that a final display luminance level, representing a luminance of the light modulated by the spatial modulation element, is lower than a predetermined first luminance level, where the light quantity adjustment target represents a adjustment target value in the light quantity, employed by the light quantity adjustment section.

  • Patent number: 8228351
    Abstract: An image display apparatus may include a light source, a spatial light modulation element, light quantity adjustment section, image correction section and re-adjustment section. The re-adjustment section may perform 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 section, in a case that a final display luminance level, 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 section, and the light quantity adjustment target represents a adjustment target value in the light quantity, employed by the light quantity adjustment section.
