摘要： The disclosed image sensing device has a light measuring circuit for measuring the luminance of an object to be photographed or recorded and a photometric characteristic control circuit for shifting the photometric characteristic of the light measuring circuit from one characteristic to another according to change-over between a still picture taking mode and a motion picture taking mode. The photometric characteristic control circuit makes the photometric sensitivity distribution of the light measurement circuit more averaged or uniformalized in the motion picture taking mode than in the still picture mode.
