Abstract: Image capturing systems with interline CCD structures designed to reduce the delay between captures of subsequent image frames are disclosed. Proposed interline CCD structures include two or more sets of storage units associated with a given set of photodetecting elements, where each photodetecting element is associated with one storage unit of each set of storage units in that the charge generated by the photodetecting element during the acquisition of a particular image frame (i.e. during a particular exposure period) may be stored any one of these storage units prior to read-out. Providing multiple sets of storage units allows read-out of charge corresponding to one image frame and stored in one set of storage units while accumulating charge corresponding to another image frame in another set of storage units, thus reducing the delay between captures of different image frames. Consequently, errors and artifacts of the image capturing system can be minimized.
