Abstract:
1. An image display apparatus that adjusts a displayed image by changing a flux of light, comprising: an image signal transformation device that transforms a brightness level of image signals of a plurality of primary colors of a displayed image into a color space that includes a chromaticity and a lightness; a prediction device that predicts a chromaticity of the color space when the flux of light is changed; a correction device that corrects the chromaticity in the color space that has been transformed by the image signal transformation device, in accordance with a prediction made by the prediction device; an expansion device that expands the lightness in the color space that has been transformed by the image signal transformation device; and a color space transformation device that transforms the color space that includes the lightness expanded by the expansion device and the corrected chromaticity into image signals of a plurality of primary colors; and an imager that is controlled in accordance with the image signals outputted by the color space transformation device.
