An imaging apparatus comprising an image sensor including a plurality of focus detection pixels for generating a focus detection image and a plurality of imaging pixels for generating a captured image, a color ratio detection unit detecting a color ratio based on a pixel value output from a pixel in a position surrounding a processing target pixel, a color conversion unit generating a first pixel value by applying color conversion with the color ratio to a pixel value output from a pixel that is located in the predetermined direction of the processing target pixel, and an adding unit generating a third pixel value by adding a second pixel value output from the processing target pixel with the first pixel value having the same color as the second pixel value.

The present technology relates to a solid-state imaging device that can reduce the power consumption in outputting a low-resolution image, a method of driving the solid-state imaging device, and an electronic apparatus. In the solid-state imaging device, a pixel summing unit outputs a horizontally- and vertically-summed pixel signal by combining pixel signals of pixels that are aligned in a vertical direction and have different weights, and pixel signals of pixels that are aligned in a horizontal direction and have different weights, the pixels being arranged in a matrix fashion. An AD converter unit performs AD conversion on the horizontally- and vertically-summed pixel signal that is output from the pixel summing unit. The present technology can be applied to solid-state imaging devices and the like.
