  • Patent number: 8224069
    Abstract: When a feature point extractor sets feature points on one of the images acquired by a first and second image acquirer, a template setting unit sets a base template containing a feature point onto an edge-extracted image of the acquired image. If the image within the base template is segmented by an edge, the template setting unit sets a transformed template, wherein a segmented sub-region that does not contain the feature point is deleted from the base template, and a region equal in area to the deleted region is added to the sub-region that does contain the feature point. A distance computing unit conducts template matching with respect to the one or more other images using either the base template or the transformed template, and computes the shooting distance to the matching feature point.

  • Publication number: 20110187886
    Abstract: An image pickup control unit displays either one of a picked-up image by a first image pickup unit and a picked-up image by a second image pickup unit on a display unit as a finder image. A feature detecting unit calculates a distribution of brightness values or brightness dispersion for each of the picked-up images by the first and second image pickup units, thereby detecting features of the two picked-up images. A sameness determining unit determines the sameness between both picked-up images based on the detected features, and determines that an abnormality like the unexpected appearance of an obstacle is present when the feature largely differs. When it is determined that an abnormality is present, a warning processing unit simultaneously displays both picked-up images on the display unit, or displays the picked-up image including the abnormality on the display unit as a finder image.
