  • Patent number: 10506177
    Abstract: There are provided an image processing device, image processing method, image processing program, image capture device, and image display device that prevent increase of computational complexity in image enlargement while mitigating degradation in image quality. An image input unit inputs a planar image signal containing signal values of pixels arranged on a plane and depth information including depth values corresponding to the pixels. An interpolation unit calculates a signal value for an interpolation coordinate between pixels on the plane by interpolating between the signal values of adjacent pixels which are present within a predetermined range from the interpolation coordinate. A weight decision unit determines a weighting factor for use in the interpolation based on the depth value of a reference pixel that is closest to the interpolation coordinate and the depth value of an adjacent pixel.
