Abstract
A focal point detection device according to the present invention comprising: an image sensor having an imaging pixel and a focal point detection pixel; a camera-shake preventing section which moves the image sensor in a direction perpendicular to the optical axis of the photographic lens to correct camera shake and also outputs information on the movement of the image sensor; a calculation section to calculate a focal point adjustment signal, based on the output of the focal point detection pixel; a memory to store a correction value for correcting the focal point adjustment signal, depending on the image height position of the focal point detection pixel; and a correction section to correct the focal point adjustment signal, depending on the output of the memory, the information output by the camera-shake preventing section, and the position of the focal point detection pixel.
