Patent ID: 7071983

Claim:
A photosensitive system, comprising: an array of photosensitive elements; a charge transfer register having a at least a first cell and a second cell; a transfer gate coupled to the photosensitive elements and the charge transfer register; and a controller configured to enable the transfer gate between successive sample exposure periods and to disable the transfer gate during the sample exposure periods, the controller further configured to control a duration of a time period that the transfer gate remains continuously enabled between the successive sample exposure periods based on a desired duration for one of the sample exposure periods, wherein charges from at least one of the photosensitive elements are shifted by the charge transfer register from the first cell to the second cell causing charges transferred into the second cell from another of the photosensitive elements to be mixed in the second cell with the charges from the at least one photosensitive element while the transfer gate is enabled between the successive sample exposure periods.
