Patent ID: 8643752

Claim:
A method of reducing motion blur in a digital image produced by a moving charge-coupled device (CCD), comprising: integrating signal charges at photodiode wells from successive exposures on the CCD, each photodiode well corresponding to a pixel of the digital image, by exposing the CCD to a subject, wherein the duration of each successive exposure is chosen to be a fraction of a total exposure duration that is proportional to a speed at which the CCD physically moves; shifting the signal charges for each successive exposure in a direction opposite to a direction of CCD motion as the CCD physically moves, wherein a distance of the shift is proportional to a speed at which the CCD physically moves; accumulating the signal charges from the successive exposures in storage lines of the CCD to enhance the light intensity of each pixel, wherein the integrating and shifting cause the signal charges to be accumulated with other signal charges that correspond to a same portion of the subject; shifting the accumulated signal charges from the storage lines to a serial shift register; and outputting the accumulated signal charges from the serial shift register to produce a digital image.
