Optical image information detecting apparatus
Abstract:
In an image sensor of this invention, each image information detecting unit has one photoelectric converter, eight signal fetch gates for fetching signal charges from the photoelectric converter, and eight store and forward CCD arrays extending parallel to one another and connected to the signal fetch gates, respectively, for storing the signal charges. Only one of the eight signal fetch gates is switched ON in each electronic shuttering cycle synonymous with a photography cycle, to deliver a signal charge to a corresponding one of the store CCD arrays. When signal charges have been stored in all the first cells of the store CCD arrays after eight electronic shuttering cycles, the eight store CCD arrays perform one transfer operation all at once, to forward, in parallel, the eight signal charges to the next cells. This operation is repeated to perform high-speed photography at eight times the transfer speed of the store CCD arrays.
