STEREOSCOPIC IMAGE PROCESSING APPARATUS, STEREOSCOPIC IMAGE PROCESSING METHOD, AND RECORDING MEDIUM

摘要

The present invention makes it possible to adaptively convert distribution of disparities or depths of a stereoscopic image according to a visual property of a human related to stereopsis. A stereoscopic image processing apparatus according to the present invention is a stereoscopic image processing apparatus which receives an input stereoscopic image, and converts distribution of disparities or depths of the input stereoscopic image, the apparatus includes a planar region extracting unit (31) which extracts a planar region in the stereoscopic image; a non-planar region conversion processing unit (exemplified using non-planar region disparity conversion processing unit (32)) which performs a first conversion process in which the disparity or the depth is converted with respect to a non-planar region which is a region other than the planar region; and a planar region conversion processing unit (exemplified using planar region disparity conversion processing unit (33)) which performs a second conversion process in which the disparity or the depth is converted using a conversion property which is different from that in the first conversion process with respect to the planar region. Here, the first conversion process is a process in which a conversion based on a non-linear conversion property is performed related to the disparity or the depth with respect to the non-planar region.
