Abstract
Abstract A still video camera includes a solid-state image pickup device including a photosensor section, a vertical transfer section for vertically transferring charge from the photosensor section, and a horizontal transfer section for outputting the charge from the vertical transfer section to the outside. The solid-state image pickup device is arranged to change an exposure time. Exposure is started at an end of transfer of the charge from the photosensor section to the vertical transfer section. Emission of an electronic flash is started on the basis of a predetermined shutter speed when a predetermined period of time has elapsed. The charge of the photosensor section in the solid-state image pickup device is transferred to the vertical transfer section when an amount of light reflected by an object to be photographed reaches a predetermined value, thereby completing the exposure.
