Abstract
A solid-state color image sensor in which a photosensor region comprises a plurality of parallel transfer electrodes and a plurality of channel stops extended at right angles to the transfer electrodes; the photosensor region is divided into a plurality of elements each comprising a predetermined number of transfer electrodes; one of the transfer electrodes of each element which are adjacent to other elements is optically shielded; and voltages are applied to the transfer electrodes of each element in such a way that the potentials below the optically shielded transfer electrode, the transfer electrode or electrodes which do not collect signal charges, the channel stop and the transfer electrode or electrodes which collect the signal charges become progressively deeper in the order named. Mixtures of the signal charges from the different color picture elements can be avoided, so that an image with a higher degree of color purity can be obtained.
