ABSTRACT:
Storage charges held in a photosensitive section of a CCD, serving as a solid-state imaging device, are discharged in response to a discharge field shift pulse supplied from a driver. When a first signal read field shift pulse is supplied from the driver, storage charges held in the photosensitive section are simultaneously transferred to a high-speed transfer section, and then transferred from the high-speed transfer section to a field memory, in units of lines and at a high speed. When a second signal read field shift pulse is supplied from the driver, storage charges held in the photosensitive section are simultaneously transferred to the high-speed transfer section. The charges stored in the field memory are transferred, in units of liens, by a line transfer section, whereby a video signal of an odd-numbered filed is obtained. Subsequently, the charges stored in the high-speed transfer section are transferred, in units of liens and at a high speed, to the field memory, from which they are then transferred, in units of liens, by the line transfer section, whereby a video signal of an even-numbered field is obtained.
