Systems and Methods for Implementing Time Delay Integration Imaging Techniques in Conjunction with Distinct Imaging Regions on a Monolithic Charge-Coupled Device Image Sensor
Systems and methods in accordance with embodiments of the invention implement TDI imaging techniques in conjunction with monolithic CCD image sensors having multiple distinct imaging regions, where TDI imaging techniques can be separately implemented with respect to each distinct imaging region.

A camera system can include: a CCD image sensor including a plurality of pixels that define at least two distinct imaging regions, where pixels within each imaging region operate in unison to image a scene differently than at least one other distinct imaging region. In addition, the camera system is operable in a time-delay integration mode whereby time delay-integration imaging techniques are imposed with respect to each distinct imaging region.
