Patent ID: 8049802

Claim:
A camera comprising: an imaging array comprising a plurality of CMOS pixel sensors organized as a plurality of columns and rows of pixel sensors, said columns being characterized by a column direction, each pixel sensor generating an exposure signal representative of a quantity of light received by said pixel sensor; an imaging system that causes a portion of an image of a scene to be projected on said imaging array such that said image of said scene moves across said imaging array in said column direction; and a controller that causes said imaging array to form first and second images of said scene at first and second times, said first and second times being chosen such that said image of said scene moves a predetermined number of rows, greater than or equal to one, of said imaging array between said first and second times, each image comprising a plurality of pixel values, one such pixel value corresponding to each of said pixel sensors, wherein said controller combines pixel values from a first row in said first image with pixel values from a second row in said second image, said first and second rows being separated by said predetermined number of rows.
