Abstract
Provided is a solid-state imaging element provided with a sample-and-hold circuit, the solid-state imaging element improving the image quality of image data. A first pixel generates a predetermined first reset level and a first signal level according to an exposure amount. A second pixel generates a predetermined second reset level and a second signal level according to an exposure amount. A sample-and-hold circuit performs reset level sampling processing of causing a first individual capacitor to hold the first reset level and causing a second individual capacitor to hold the second reset level, and correlated double sampling processing of causing a common capacitor and the first individual capacitor to hold a first output level according to a difference between the first reset level and the first signal level and causing the common capacitor and the second individual capacitor to hold a second output level according to a difference between the second reset level and the second signal level.
