Abstract
A camera is provided with a distance measurement device having a plurality of distance measurement regions and outputting distance measurement information of each distance measurement region, a light adjustment device having a plurality of light adjustment regions including regions substantially coinciding with the distance measurement regions, and an auxiliary light emitting device for emitting auxiliary light in distance measurement. The auxiliary light emitting device emits auxiliary light when low contrast is detected in at least one of the plurality of distance measurement regions. When auxiliary light is emitted, the flash light emission quantity is controlled based on the distance measurement information in auxiliary light emission and an output from the light adjustment device.
