Solid state imager with transfer smear suppression for moving and stationary images |
摘要 |
A field transfer imager is erased after every field transfer, prior to a new field of pixels-descriptive charge packet being accumulated in the successive charge transfer stages of the charge transfer channels of the image register. The image register is operated to supply a field of "null" charge packets for each field of pixel-descriptive charge packets it supplies. The "null" charge packets and pixel-descriptive charge packets are temporarily stored in respective field storage registers, and converted a line at a time to serial format for sensing. The resulting "null" samples and pixel-descriptive samples are differentially combined to provide pixel-descriptive samples with suppressed dark current ramp components and, assuming field-rate shuttering of the imager is not used, with suppressed transfer smear components.
