LIGHT EMITTING APPARATUS AND METHOD FOR CONTROLLING THE SAME
First 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 each of the light sources;
a first malfunction detecting unit configured to detect any malfunction of each of the light sources;
a second malfunction 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.

9. A method for controlling a light emitting apparatus having a plurality of light sources for which light emission is controllable independently from each other, the method for controlling the light emitting apparatus comprising:
-
a step of detecting a brightness of each of the light sources by means of a brightness sensor; a first malfunction detecting step of detecting any malfunction of each of the light sources; a second malfunction detecting step of detecting any malfunction of the brightness sensor; and a control step of determining a light emission control value of each of the light sources so as to decrease a difference between a target value of a detected value of the brightness of each of the light sources to be detected by the brightness sensor and the detected value of the brightness of each of the light sources detected by the brightness sensor, the target value being stored in a storage unit, wherein; the light emission control value of each of the light sources is allowed to be set to a fixed value in the control step 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 19, 20)
