Claim:
1. A focus adjustment device, comprising: 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 angle of emission range of light flux that is emitted towards the image sensor, in accordance with image height, a second memory which stores information relating to characteristics of the image sensor, and a vibration section which corrects hand shake by causing movement of the image sensor in a direction perpendicular to the optical axis of the photographing lens, and outputs information relating to the movement of the image sensor, and a calculation section which calculates information for focus adjustment based on output of the first memory, output of the second memory and output of the vibration section, wherein the calculation section calculates information relating to corrected angle of emission range based on information related to the angle of emission range and information relating to the movement of the image sensor, and calculates information for focus adjustment based on the information relating to the corrected angle of emission range and information relating to characteristics of the image sensor.
