Abstract: An apparatus that can obtain a clear image by correcting blurs of respective object images even in a case where a plurality of objects with different blurs exists within an image. Local PSF estimating section estimates a PSF for each small region. PSF form identifying section identifies forms of the estimated PSFs of the small regions and groups local estimated PSFs such that small regions having the PSF forms with high similarity belong to the same group. Small region integrating section integrates adjacent small regions that are grouped in the same group. Due to this, object images blurring in a similar way can be accurately separated. As a result of this, a perspective separation of the objects and a separation of moving objects become possible from just one input image without using a plurality of cameras or additional devices (a distance sensor, etc.).
