Abstract
A lighting apparatus includes light emitters to illuminate an illuminated member. Relationship information about a relationship between variations in the amount of light emitted by each of the light emitters and variations in an amount of light received on each of the different portions of the illuminated member are stored in memory. A controller is operable to control individually, based on the relationship information, the amount of the light emitted by each of the light emitters so that the amount of light received on the different portions of the illuminated member are substantially even.
