Abstract
Methods and apparatus for image acquisition utilize a charge coupled device having a photosensitive region that responds to an applied transfer signal by transferring charge accumulated on the collection sites to the corresponding readout sites. The non-photosensitive region responds to a read signal, applied independently of the transfer signal, by outputting (e.g., to the host camera or image acquisition system) charges on the readout sites. The methods and apparatus take advantage of the inherent storage capability of the non-photosensitive sites by using them to hold image information pending application of the readout signal, thereby, conserving host resources.
