ABSTRACT:
A solid image-sensing device, in which CCDs or the like are used, has a light-receiving part comprising a plurality of photosensitive cells disposed linearly and functioning to generate charges corresponding to light information projected incidently thereon, first and second charge-transfer paths on opposite sides of this light-receiving part, and a third charge-transfer path for deriving charges from the first and second charge-transfer paths, signals being read out alternately from the first and second charge-transfer paths at the time of high-speed readout, signals from the first and second charge-transfer paths being collected and read out through the third charge-transfer path during low-speed readout.
