An image sensor includes a solid-state image pickup device, an optical system, and a flash. The solid-state image pickup device has an electronic shutter function of outputting accumulated signal charges at a timing corresponding to a shutter speed. The optical system collects incident light to an image pickup area of the solid-state image pickup device. The flash irradiates light to an object to be photographed by the solid-state image pickup device. The solid-state image pickup device includes a pulse generator circuit for generating one or more of an electronic shutter pulse for controlling an accumulation time of signal charges by using the electronic shutter function, an optical system movement pulse for controlling movement of the optical system, and a flash pulse for controlling an emission timing of the flash. |
