Abstract
A focal point detection device comprising: an image sensor having a focal point detection pixel, a pixel data generation section to generate pixel data of a basis part and a reference part corresponding to a predetermined AF area using an output of the focal point detection pixel, a plurality of filter sections having different frequency characteristics to perform filter processing on the pixel data, a detection section to detect contrast of subject image data configured with a plurality of pieces of pixel data of the basis part and the reference part, and a calculation section to select a filter section from among the plurality of filter sections depending on the contrast output by the detection section, to perform correlation calculation using pixel data on which the filter processing is performed by the selected filter section to calculate a defocus amount.
