Claim:
1. A light emitting apparatus having a plurality of light sources for which light emission is controllable independently from each other, the light emitting apparatus comprising: a brightness sensor which detects a brightness of at least one of the plurality of light sources; a first detecting unit configured to detect any malfunction of each of the light sources; a second detecting unit configured to detect any malfunction of the brightness sensor; a storage unit configured to store a target value of a detected value of the brightness of each of the light sources to be detected by the brightness sensor; and a control unit configured to determine a light emission control value of each of the light sources so as to decrease a difference between the target value and the detected value of the brightness of each of the light sources detected by the brightness sensor, wherein: the control unit allows the light emission control value of each of the light sources to be set to a fixed value regardless of the difference between the target value and the detected value detected by the brightness sensor if the malfunction of at least any one of the light source and the brightness sensor is detected.
