Abstract
A focus adjustment device comprises an image sensor having imaging pixels and focus detection pixels, which subjects light flux that is passed through a photographing lens to photoelectric conversion and outputs an image signal, a first memory which stores information relating to incident angle range of light flux that is incident towards the image sensor, a second memory which stores information relating to characteristics of the image sensor, and a calculation section which calculates information for focus adjustment based on output of the first memory and output of the second memory.
