Abstract
An image display apparatus according to the present invention includes: a display panel configured to display an image; a light emitting unit configured to emit light onto the display panel; an acquisition unit configured to acquire an expansion parameter to expand a reproducible color gamut, which is a range of colors that the image display apparatus can reproduce, from a reference color gamut to an expanded color gamut; and a conversion unit configured to generate output image data by performing, on input image data, color conversion processing to convert a color outside the expanded color gamut into a color within the expanded color gamut based on the expansion parameter, wherein the light emitting unit increases an emission brightness of the light emitting unit based on the expansion parameter.
