Patent ID: 7715651

Claim:
A method for enhancing an image generated using an imaging system, the imaging system comprising a plurality of imaging sensors, including a first imaging sensor and a second imaging sensor, the method comprising: receiving a first digital number at an image correction system, wherein the first digital number is a representation of a brightness value of a pixel for the first imaging sensor; receiving a second digital number at the image correction system, wherein the second digital number is a representation of a brightness value of the pixel for the second imaging sensor; determining, using the image correction system and the first digital number, whether to correct for a non-linear response of the first sensor to an amount of radiance received by the first sensor, wherein said determining comprises identifying a roll-off point for the first sensor, wherein the first sensor has a substantially non-linear response to an amount of radiance it receives after the roll-off point is met; and generating, using the image correction system, a final digital number based on the first digital number and the second digital number, wherein the final digital number is a corrected representation of the brightness value of the pixel for the first imaging sensor, wherein said generating step is performed if the first digital number has a value greater than a digital number associated with the roll-off point.
