Abstract: An image processing apparatus is designed to process pixel outputs of an imaging element including imaging pixels and phase-difference detecting pixels. The apparatus includes a pixel mixing unit and an image processing unit. The pixel mixing unit mixes the pixel outputs. The image processing unit corrects the pixel outputs to prevent the phase-difference detecting pixels from degrading image quality, by using at least one of information selected from a group consisting of the number of mixed pixel outputs of phase-difference detecting pixels having the same opening direction and the number of mixed pixel outputs of imaging pixels having the same opening direction.

Abstract: An imaging apparatus includes a high-frequency pattern detector calculating a difference or a ratio between a value obtained by integrating averages of pixel outputs of a first pixel group arranged in identical positions in a vertical direction with respect to a focus detection pixel or in identical positions in a vertical direction with respect to another focus detection pixel located around the focus detection pixel and a value obtained by integrating averages of pixel outputs of a second pixel group arranged in positions shifted from the first pixel group in the horizontal or vertical direction, and sets a high-frequency degree in accordance with a magnitude of the difference or the ratio. An application determination unit increases the mixing rate of the focus detection pixel when the high-frequency pattern degree is high.
