Abstract:
A method and system is disclosed for reducing motion blur using CCD charge shifting. In one embodiment, photodiode wells are exposed for a set of successive exposures with each exposure duration being a fraction of a total exposure time. After each successive exposure, the photodiode wells integrate signal charges and shift them to corresponding storage lines. The shifted signal charges are then shifted along the storage lines for a specified number of storage units. At the same time, the CCD is moved in the direction of a leading edge of the CCD. The photodiode wells are then exposed for another exposure to produce another set of signal charges, which are shifted to the storage lines. Signal charges from the successive exposures are accumulated at the storage lines. After all successive exposures have been taken, the accumulated signal charges are shifted to a serial shift register and output to form an image.
