Abstract
There is provided a focal point adjustment device, comprising: a first memory to store information on an emission angular range of a light flux emitted toward an image sensor; a second memory to store the information on characteristics of the image sensor; a camera-shake preventing mechanism to correct camera shake by moving the image sensor, and to correct camera shake by rotating the image sensor in a plane perpendicular to the optical axis of the photographic lens and also output information on the movement and information on the rotation; and a calculation circuit to correct image height information at a range-finding position where the output of the focal point detection pixel is used, based on the information on the movement and the information on the rotation output by the camera-shake preventing mechanism, and calculate information for the focal point adjustment, based on the corrected image height information.
