Claim of US Patent No. 9,307,607

1. A light source apparatus formed of a plurality of light emission areas capable of individually controlling emission brightness
and emission colors thereof, the light source apparatus comprising:
a brightness determination unit configured to determine emission brightness of each of the light emission areas;
a determination unit configured to determine whether a color of a target light emission area, which is one of the light emission
areas, changes by changes in emission brightnesses of light emission areas other than the target light emission area, based
on the emission brightness of each of the light emission areas determined by the brightness determination unit;

a color determination unit configured to determine an emission color of each of the light emission areas based on a determination
result by the determination unit; and

a control unit configured to cause each of the light emission areas to emit light of the emission color determined by the
color determination unit, at the emission brightness determined by the brightness determination unit,

wherein in a case where the determination unit determines that the color of the target light emission area changes, the color
determination unit determines the emission color of the target light emission area in such a manner so as to suppress the
change in the color of the target light emission area.
