Patent ID: 7920182

Claim:
A digital camera comprising: at least one sensor adapted to provide a digital representation of a portion of a field of view; an optical system causing a plurality of locations within the field of view to become incident on the at least one sensor; a lookup table, operative to store a plurality of sets of values, each set related to a rectangular region of interest within the field of view, the stored values including values for scanning velocity and time between signal extraction, bias and gain factors, and pixel dilution parameters; a timing generator and controller, operative to cause the plurality of locations within the field of view to become incident on the at least one sensor at a given velocity and to command video signal extraction from the at least one sensor at a given time, the values for scanning velocity and time between signal extraction being obtained from the lookup table; a pixel correction module, operative to add a bias factor to any pixel within the digital representation of the portion of a field of view and to further multiply the pixel by a gain factor, the values for bias and gain factors being obtained from the look-up table; one or more dilutor modules, each operative to select or combine pixels within the digital representation of the portion of a field of view to form a diluted digital image representation, the parameters for pixel dilution being obtained from the from the look-up table.
