Abstract:
A solid state imaging element (100) includes: a successive approximation type analog-digital conversion circuit (140) converting an analog pixel signal received from a pixel of a pixel array portion (110) to a digital code; and a first noise detection circuit (130-1) connected to a DAC (Digital to Analog Converter) output node inside the successive approximation type analog-digital conversion circuit (140) and detecting power noise supplied to the pixel of the pixel array portion (110) to output a detection result to the DAC.
