Image sensors.

摘要

A CCD frame transfer image sensor wherein the effective integration period can be shortened by electrical means. The sensor comprises an image section (9) having a first photo-sensitive portion of an array of CCD channels (1), and a store section (11) having a second light shielded portion ofthe array (1). Means (18) are provided for controlling the potentials applied to the control electrodes (5) of the array so as to transfer along the channels charge generated in the image section (9) into either a charge sink structure (15) or the store section (11).
