  • Patent number: 9819927
    Abstract: Disclosed is an image processing device for generating disparity information from a first image and a second image, wherein the first image is captured by a first capture unit and the second image is captured by a second capture unit. The image processing device includes a disparity detector configured to detect disparity information of a pixel or a pixel block of the second image by correlating the pixel or the pixel block of the second image with each of pixels or each of pixel blocks of the first image within a detection width. The disparity detector is configured to detect the disparity information of the pixel or the pixel block of the second image more than once by changing a start point of pixels or pixel blocks of the first image within the detection width.

  • Patent number: 9794543
    Abstract: An information processing apparatus for processing stereo images of an object includes a disparity calculator to calculate a disparity of the stereo images. The disparity calculator includes an evaluation value calculator to calculate a correlation evaluation value in a search range set for the stereo images; an extreme value detector to detect an extreme value of the correlation evaluation value; a threshold setting unit to set a threshold range for the detected extreme value; a counting unit to count the number of the extreme value existing within the threshold range; and an updating unit to update the set threshold range to a new threshold range when a new extreme value indicating a higher correlation level of the disparity compared to the set threshold range is detected. The counting unit counts the number of the extreme value in a threshold range updated most recently in the search range.
