ABSTRACT:
A solid-state image pickup device in which a plurality of optoelectric transducing elements are vertically and horizontally arranged into a matrix array, groups of optoelectric transducing elements arrayed in first rows serve as picture elements having a red spectral characteristic, groups of optoelectric transducing elements arrayed in second rows serve as picture elements having a blue spectral characteristic, and vertical charge transfer paths and groups of picture elements arrayed in the column direction are alternately arranged. In accordance with the invention, segmental portions of each of the vertical charge transfer paths, which positionally correspond to respective ones of the picture elements, include portions where charge transfer electrodes are layered and portions where no transfer electrodes are layered, an impurity is distributed in predetermined portions of the vertical charge transfer path under the charge transfer electrodes and the portions with no charge transfer electrodes in the charge transfer direction, thereby to set up potential levels of different depths, potential wells, that are caused by applying a signal of a predetermined voltage to the charge transfer electrodes when an image is being sensed, are used as picture elements of green, and signal charge is transferred by applying a drive signal recurring at predetermined periods to the charge transfer electrodes.
