Abstract: In a CMOS image sensor of the invention, a dynamic range is varied at a per-pixel level by a light amount to prevent saturation without degrading color reproduction of an overall image. A photo diode generates charges in accordance with a received light amount. A drive transistor amplifies the charges generated in the photodiode at a given gain. Further, a saturation detector receives an output voltage from the drive transistor and judges the image sensor saturated if the output voltage is beyond a limited level. A switch switches on/off in response to the judgment of the saturation detector. Also, a plurality of floating diffusions store the charges of the photodiode transferred through the switch. The floating diffusions are selectively connected to both the photodiode and a gate of the drive transistor at on/off the switch.
