Patent ID: 7031556

Claim:
An image sensor for ultrahigh-speed image capturing comprising: a plurality of charge transfer paths each constituted by a charge coupled device having a plurality of elements and disposed parallel to each other; a plurality of charge transfer electrodes intersecting the charge transfer paths and provided for each element of the charge transfer paths; an intercepting film covering the charge transfer paths and said charge transfer electrodes so as to intercept an incident ray; and a plurality of windows provided in the intercepting film and allowing the incident ray to pass therethrough, wherein a charge corresponding to an intensity of the incident ray is generated at the element of the charge transfer path corresponding to each window, and the generated charge is transferred on the charge transfer path by voltages applied from the charge transfer electrodes, and wherein each of the charge transfer electrodes has a larger size in a charge transfer direction at portions corresponding to the windows than that at portions covered with the intercepting film.
