  • Patent number: 9189893
    Abstract: To generate an image that enables effective suppression of the occurrence of binocular rivalry and that facilitates stereoscopic vision. A left-eye image feature point extraction unit (13b) and a right-eye image feature point extraction unit (13d) extract feature points from a left-eye image and a right-eye image, respectively. A number-of-non-corresponding-points calculation unit (13g) calculates, in a case where the feature points in one image among the left-eye image and the right-eye image, which are extracted by a left-eye image feature point extraction unit (13b) and a right-eye image feature point extraction unit (13d), are shifted a certain distance in the horizontal direction, the number of feature points in the one image that do not correspond to the feature points in the other image, for each shift distance. A disparity value adjustment unit (13h) adjusts a disparity value between the left-eye image and the right-eye image in accordance with the number calculated for each shift distance.

  • Publication number: 20150304625
    Abstract: An image processing device includes a viewing environmental light information acquirer and a sense-of-depth parameter adjustment amount calculator to adjust a sense-of-depth parameter (i.e., a parameter related to binocular cues and/or monocular cues) according to environmental light in a viewing environment. The viewing environmental light information acquirer is configured to acquire viewing environmental light information that is information related to environmental light in a viewing environment of a display device. The sense-of-depth parameter adjustment amount calculator is configured to calculate an adjustment amount of a sense-of-depth parameter of monocular cues and/or binocular cues used when the display device displays an image represented by image data based on the viewing environmental light information and image auxiliary data.

  • 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.

  • Publication number: 20140176539
    Abstract: There is provided a stereoscopic image processing apparatus with which a disparity can be correctly estimated even for an image in which a disparity has a vertical component. A stereoscopic image processing apparatus (10) includes an input unit (11) that receives a plurality of viewpoint images, an evaluation value calculation unit (12) that calculates, for a plurality of viewpoint images that have been received, an evaluation value relating to pixel similarity between viewpoint images and disparity continuity between viewpoint images, and a disparity map creation unit (13) that selects a combination of disparities of each pixel, for which the evaluation value that has been calculated is a minimum evaluation value, as a disparity of the pixel and creates a disparity map having a horizontal component and a vertical component.

  • Publication number: 20140092222
    Abstract: To provide a stereoscopic image processing device that can display an image that can be easily viewed stereoscopically by a viewer even in the case where there is a difference other than parallax between viewpoint images by reducing the difference without calculating the size of the difference. A stereoscopic image display device (1) includes a reference viewpoint image selection unit (12) that selects one of a plurality of viewpoint images as a reference viewpoint image, a parallax calculation unit (13) that calculates a parallax map between the reference viewpoint image and the remaining viewpoint image, an image generation unit (14) that generates a new remaining viewpoint image that corresponds to at least the remaining viewpoint image from the parallax map and the reference viewpoint image, and a display unit (16) that displays a stereoscopic image that includes at least the new remaining viewpoint image as a display element.
