1. A light source control apparatus, comprising:
- an image change determination unit that determines presence or absence of at least one of a change of an image signal and the image signal; and
a light source controller that reduces luminous output of a light source at a predetermined decreasing rate when the image change determination unit determines at least one of no change of the image signal and absence of the image signal.
