Abstract
Charges are transferred from vertical charge transfer devices of a solid-state image sensing device to horizontal charge transfer device via buffer storage cells. Charges obtained from a unessential area out of the transferred charges are discarded by operating the horizontal charge transfer device, and charges obtained from a specific area out of the transferred charges are normally read out by operating the horizontal charge transfer device. When there is a remaining charge in the horizontal charge transfer device after reading charges from the specific area, charges are transferred from the vertical charge transfer devices to the horizontal charge transfer device so that the remaining charge is added only to a charge obtained from the unessential area. Further, charges are transferred in the vertical charge transfer devices in the vertical direction while discarding unessential charges.
