  • Patent number: 9729844
    Abstract: In the related art, it was difficult to compare lengths of a plurality of objects which were present at different places. However, it is possible to easily compare lengths of photographed objects using an image capturing device which displays a length of an object which is calculated based on parallax information, by obtaining an image in which the object is photographed and the parallax information corresponding to the image as inputs, the device including an object extraction unit which extracts an image of an object using the parallax information from the photographed image; a comparison data maintaining unit which maintains the image of the object and the length of the object; an object comparison unit which compares the length of the object which is extracted using the object extraction unit to a length of comparison data which is extracted from the comparison data maintaining unit; and an image composition unit which combines a comparison result with the photographed image, and outputs the image.

  • Patent number: 9438877
    Abstract: A disparity calculating device 100 obtains a base image from a first camera 1 and a reference image from a second camera 2. An image dividing unit 101 divides each of the base image and reference image into multiple regions in accordance with dividing conditions set by a condition setting unit 102. A correction amount determining 103 calculates image shift amount for each of the divided regions, and determines correction amount based on the images shift amount thereof. A disparity calculating unit 104 performs correction of the image on each region of divided base images and divided reference images obtained from the image dividing unit 101 based on correction amount determined by the correction amount determining unit 103 to obtain disparity based on the images after correction.
