Abstract
An image display apparatus includes: a light source unit including three or more light sources, combining lights from the light sources and emitting the combined light; a wavelength detector that detects, for each light source, wavelength information indicating the wavelength of light from the light source; a color value determiner that determines, for each light source, from the wavelength information, a color value indicating a color of light from the light source in a predetermined color space; a correction value determiner that determines, based on the color values, a correction value for correcting a ratio between the intensities of lights from the light sources so that the color of the combined light is a color to be displayed; and a driver that drives the light sources so that the ratio between the intensities of lights from the light sources is a ratio corrected based on the correction value.
