Abstract
The present technology relates to a solid-state imaging element and an imaging apparatus that provides an ample dynamic range. The solid-state imaging element includes a pixel array section and a readout load section. The pixel array section has a readout pixel and a reference pixel. A pixel signal proportional to an amount of incident light is read out from the readout pixel. The reference pixel has characteristics similar to those of the readout pixel. The readout load section forms a differential amplification circuit together with the readout pixel and the reference pixel and inputs, to the reference pixel, a pseudo-dark current signal corresponding to a dark current signal that occurs in the readout pixel, thus canceling the dark current signal. The present technology is applicable to a CMOS image sensor.
