Abstract:
An image processing apparatus includes: an image pickup device with image creating pixels for creating images and pairs of phase difference detection pixels of two types for creating pixel values for in-focus state judgment; a detection unit detecting the edge of a first figure formed by the pixel values of the image creating pixels and the edge of a second figure formed by the pixel values of the pairs of phase difference detection image pixels; and a compensation unit that, if a defective pixel is included in phase difference detection pixels of one type, calculates a distance between the second figure regarding phase difference detection pixels of the other type and the first figure on the basis of the detected edges, and compensates for the pixel value of the defective pixel on the basis of the calculated distance and the pixel values of phase difference detection pixels of another type.
