Abstract
To improve the image quality in a solid-state imaging element that performs exposure by a global shutter scheme. The solid-state imaging element includes a photoelectric conversion film, an upstream circuit, and a sample-hold circuit. The photoelectric conversion film converts incident light into a charge. The upstream circuit sequentially generates a reset level according to an amount of the charge at a time of a start of exposure and a signal level according to an amount of the charge at a time of an end of exposure, and outputs the reset level and the signal level to an upstream node. The sample-hold circuit causes the reset level and the signal level to be held at mutually different capacitive elements.
