US Patent 7606479 Image-taking apparatus

A digital camera is provided with an emission section which emits independently controlled light to each of multiple emission areas and a light measurement/distance measurement CPU which calculates the amount of light to be emitted at actual emission based on the amount of reflected light of pre-emission and causes the emission section to perform actual emission with the calculated amount of emitted light. The light measurement/distance measurement CPU causes a relatively large amount of light to be emitted to a part of the multiple emission areas in comparison with the other emission areas when pre-emission is performed.
