Abstract
Shading correction is realized without sacrificing a noise characteristic and a sensitivity characteristic. A solid-state imaging element includes a plurality of pixels that are arranged two-dimensionally and each outputs analog voltage proportional to electron produced by photodiode and an AD conversion section that convert analog voltages output from the pixels into digital signals. First and second pixels included in the plurality of pixels differ in conversion efficiency with which a unit quantity of electrons output from the photodiodes are converted into the analog voltages.
