Abstract
A stereoscopic image processing device including a depth map generation unit and a depth map correction unit. The depth map generation unit uses a first viewpoint image and a second viewpoint image to acquire depth values in units of blocks constituted of a plurality of pixels and generate a depth map. The depth map correction unit performs a judgment in the depth map as to whether or not a boundary region is included in a block of interest based on depth values of blocks surrounding the block of value, which is a block to be processed, and, if a boundary region is judged to be included in the block of interest, corrects the depth values in units of correction regions, which are units which are smaller than blocks, in the block of interest.
