Control device, control method, and electronic device to control an exposure amount of a pixel group

摘要

The present disclosure relates to a control device, a control method, and an electronic device that enable an adequate exposure amount to be set at high speed. A control unit controls an exposure amount of a pixel group that is a two-dimensional arrangement of a plurality of pixels. Specifically, in a first mode before recording of a photographed image is started, the control unit sets a plurality of types of exposure amounts to the pixel group, and in a second mode in which the photographed image is recorded, the control unit sets fewer types of exposure amounts than in the first mode to the pixel group. The present technology can be applied to, for example, a control device that controls a solid state imaging element.
