SOLID STATE IMAGING DEVICE AND CAMERA

摘要

In a solid state imaging device having a wide dynamic range, a pixel includes a photodiode that generates a charge in accordance with an intensity of incident light, signal generation units that generate a first voltage level in accordance with an amount of charge generated by the photodiode in an exposure period T1 and a second voltage level in accordance with an amount of charge generated by the photodiode in an exposure period T2, and signal composition units that composite the first and second voltage levels generated by the signal generation units.
