In an interpolation image generation apparatus, an input unit acquires photographed images obtained from viewpoints and imaging setting information thereof, the EPI generation unit generates an EPI from the images, an angle estimation unit estimates an angle of a straight line to which each EPI actual pixel corresponds on the EPI, an interpolation image setting unit places an interpolation image on the EPI, a correspondence detection unit detects correspondence between an actual pixel and a pixel of the interpolation image (interpolation pixel), and the correspondence detection unit evaluates likelihood of correspondence relationship between the actual pixel and the interpolation pixel, and a pixel value addition unit adds a pixel value of the interpolation pixel on the basis of the likelihood of the correspondence relationship, thereby generating an interpolation image.
