Abstract
A change amount of illuminance of a luminescent color by a light-emitting element is acquired, and based on the change amount acquired for each luminescent color, drive power to be supplied to the light-emitting element of each luminescent color is calculated in order to reduce the change amount. In addition, light emission of each light-emitting element of each luminescent color is controlled with the calculated drive power to control display of the display unit.
