Patent ID: 7170041

Claim:
An imaging system, comprising: an output device including a two-dimensional array of pixels; an illumination device including two illuminators, each illuminator capable of illuminating an object with a different color; and an input device that includes a plurality of pixel devices, each pixel device including: a multi-color sensor that provides a first electronic signal representing the object illuminated by one of the two illuminators and a second electronic signal representing the object illuminated by the other of the two illuminators; at least one transistor connected to the sensor; a first capacitor that is selectively connected to the sensor; a second capacitor that is selectively connected to the sensor; and a controller that selectively stores the entirety of the first electronic signal in the first capacitor and stores the entirety of the second electronic signal in the second capacitor; wherein each pixel device corresponds to a respective pixel in the two dimensional array of pixels.
