Abstract
Solid-state imaging devices are disclosed. In one example, a solid-state imaging device includes a pixel array with unit pixels that accumulate charge in a floating diffusion (FD) region. A pixel signal reading circuit reads a pixel signal based on the charge from the FD region of a unit pixel. The pixel signal reading circuit includes an AD converter that performs AD conversion on the pixel signal, and a determination circuit that performs brightness/darkness determination of light received by the unit pixel on the basis of the pixel signal. The determination circuit selectively controls executing or stopping of the AD conversion on a pixel signal to be subsequently read according to a result of the brightness/darkness determination.
