  • STEREOSCOPIC IMAGE PROCESSING DEVICE, STEREOSCOPIC IMAGE PROCESSING METHOD, AND RECORDING MEDIUM
    Publication number: 20150249812
    Abstract: In a stereoscopic image processing device, disparity distribution of a stereoscopic image can be adaptively transformed in accordance with visual characteristics of a person relating to stereoscopic vision. The stereoscopic image processing device includes a disparity distribution transformation section (30) that transforms disparity distribution of a stereoscopic image input by an input section (10). The disparity distribution transformation section (30) reduces a difference in disparity between adjacent pixels in an area of the stereoscopic image, in which the difference in disparity between the adjacent pixels is large.

  • STEREO-IMAGE PROCESSING APPARATUS, STEREO-IMAGE PROCESSING METHOD, AND RECORDING MEDIUM
    Publication number: 20140192156
    Abstract: A stereo-image processing apparatus capable of adaptively converting, regarding stereo vision, a parallax distribution of a stereo image in accordance with human visual performance is provided. The stereo-image processing apparatus includes a continuity detection unit (31) that detects a parallax continuous region on the basis of the discontinuity of parallax values in a stereo image and a conversion processing unit (32) that performs processing for enhancing the parallax gradient of the parallax continuous region.
