COLOR IMAGE SENSOR AND OPERATING METHOD THEREOF

摘要

There is provided a color image sensor including a sensing array and a processing unit. The sensing array includes a red pixel, a green pixel, a blue pixel, a red and green pixel and a red and blue pixel configured to output a detected signal, respectively. The processing unit is configured to calculate a signal difference between detected signals associated with the red pixel and the red and green pixel to be served as a red detected signal, calculate a signal difference between detected signals associated with the green pixel and the red and green pixel to be served as a green detected signal, and calculate a signal difference between detected signals associated with the blue pixel and the red and blue pixel to be served as a blue detected signal.
