Abstract
The present invention is directed to providing a charge-coupled device which can provide accurate signal detection while providing high speed electronic exposure control or shuttering. Exemplary embodiments can maintain charge transfer efficiency at a relatively high level even if a pixel array of the charge-coupled device is clocked rapidly (i.e., exposure control or shuttering speed is increased) for a given pixel pitch.
Claims17
Apparatus for detecting photocharge comprising:
- means for accumulating photocharge in a first photocharge accumulation area of at least one pixel and in a second photocharge accumulation area of said at least one pixel;
- and
- means operatively connected with said first and second photocharge accumulation areas for combining the photocharge accumulated in each of said first and second charge accumulation areas into a single photocharge packet.
Method for detecting photocharge comprising the steps of:
- accumulating a frame of photocharge in a first photocharge accumulation area of at least one pixel and in a second photocharge accumulation area of said at least one pixel during a first sample time;
- and
- combining the photocharge accumulated in each of the first and second photocharge accumulation areas into a photocharge packet.
