Abstract
For flash photography, a rise of a flash emission control pulse precedes emission timing by a predetermined period. A start of flash emission of a flash lamp precedes a start of exposure of an image sensor. Since the start of the emission is earlier than the start of the exposure, a period of unstable flash emission can be excluded from an exposure time T of the image sensor. The exclusion prevents a captured image from being affected by the period of unstable flash emission. Accordingly, it becomes possible to ensure high color reproducibility for photography with auxiliary light.
