Multiple images are captured where the exposure times for some of the images overlap and the images are spatially overlapped. Charge packets are transferred from one or more portions of pixels after particular integration periods, thereby enabling the portion or portions of pixels to begin another integration period while one or more other portions of pixels continue to integrate charge. Charge packets may be binned during readout of the images from the image sensor. Comparison of two or more images having different lengths of overlapping or non-overlapping exposure periods provides motion information. The multiple images can then be aligned to compensate for motion between the images and assembled into a combined image with an improved signal to noise ratio and reduced motion blur.
A method for producing multiple images with an image sensor that includes a plurality of pixels each including a photosensitive area, a plurality of vertical charge-coupled-devices (VCCDs) each comprising a plurality of charge storage elements and positioned adjacent to respective columns of pixels, transfer mechanisms for transferring charge packets from the photosensitive areas to respective charge storage elements, and a horizontal charge-coupled device (HCCD) comprising a plurality of charge storage elements, the method comprising:
