Abstract
A CMOS image sensoroutputs a differential signal (VF−VU) between a pixel signal (VF) in a period when a LEDis turned on in an exposure period and a pixel signal (VU) in a period when the LEDis turned off in the exposure period. This does not obtain a difference between a pixel signal in an exposure period and a pixel signal in a non-exposure period. It is possible to increase simplicity in utilization as well as suppressing fixed pattern noise by generating the difference between pixel signals in different exposure spans from each other.
