An image processing apparatus, image processing method, imaging apparatus, and a display device

The present invention provides an image processing apparatus, image processing method, imaging apparatus, and a display device. The image processing apparatus generates a plurality of parallax images, the plurality of parallax images has a size with an increase in the size of the defocus amount and the image shift amount increases relationship between parallax images; selected by repeating the same license , the selection of the plurality of the generated parallax image, generating a disparity image series arrangement order of selection of the selected parallax image; each pair of adjacent parallax images to parallax images included in the series is repeated to generate a plurality of interpolation processing application interpolation image; and the interpolated image is arranged between the adjacent parallax images to parallax images the interpolated output image as a moving image.
