Abstract
The present technology relates to a solid-state imaging device and a driving method thereof, and an electronic apparatus that make it possible to improve the precision of phase difference detection while suppressing deterioration of resolution in a solid-state imaging device having a global shutter function and a phase difference AF function. Provided is a solid-state imaging device including: a pixel array unit including, as pixels including an on-chip lens, a photoelectric conversion unit, and a charge accumulation unit, imaging pixels for generating a captured image and phase difference detection pixels for performing phase difference detection arrayed therein; and a driving control unit configured to control driving of the pixels. The imaging pixel is formed with the charge accumulation unit shielded from light. The phase difference detection pixel is formed in a manner that at least part of at least one of the photoelectric conversion unit and the charge accumulation unit refrains from being shielded from light. The present technology can be applied to, for example, a CMOS image sensor.
