Abstract
An image display system includes: a light source driver configured to supply, to a light source, a drive current including a first current and a second current; a processor configured to output the set value of the first current to the light source driver; and a corrector configured to perform a correction process on the first current. The processor is configured to set, based on a correspondence relationship between the gradation value and the current value of the first current, the set value of the first current to a current value determined with reference to the correspondence relationship when the gradation value is in a second gradation range in which numerical values are smaller than numerical values in the first gradation range, the correction process correcting the correspondence relationship such that a difference between a measured intensity and a target intensity of the light source falls within a prescribed range.
