  • 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: 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.

  • Patent number: 8462266
    Abstract: An image processing device and method, and an image display device and method which realizes a high-definition displayed video by reducing motion blur caused by a holding-type display system and reducing motion blurs of the displayed video caused by the time integration effect of an image sensor while suppressing deterioration of an image. The image display device includes a motion vector detection section (101) which detects a motion vector in each predetermined region between the frames of an inputted image signal, and an edge emphasis part (2) which emphasizes the high-frequency component of the inputted image signal and an interpolated image signal generated by an FRC part (100) according to the motion amount of the inputted image signal detected by the motion vector detection section (101). This compensates the high-frequency component attenuated by the time integration effect of the image sensor to reduce the apparent motion blurs to improve the sharpness of the displayed image.
