  • Patent number: 8023003
    Abstract: Provided are an apparatus and method for generating panorama images and an apparatus and method for tracking an object using the same. The apparatus for generating panorama images estimates regional motion vectors with respect to respective lower regions set in an image frame, determines a frame motion vector by using the regional motion vectors based on a codebook storing sets of normalized regional motion vectors corresponding to a camera's motion and then accumulates motion mediating variables computed with respect to respective continuous image frames to determine an overlapping region, and matches the overlapping regions to generate a panorama image.

  • Patent number: 7711262
    Abstract: Disclosed is a method of photographing a panoramic image, the method including the steps of: checking if a configuration of each scene constituting the panoramic image is arbitrarily set whenever each scene is photographed; outputting a photographic guide screen on a preview screen, the photographic guide screen overlappingly displaying a guide image of a previously photographed scene and displaying an indicator indicative of a position of a current scene; storing a corresponding photographed scene as a correspondingly numbered scene when a shutter key is input during the outputting of the photographic guide screen; and checking if a predetermined direction key or a completion key is input, determining that all scenes are photographed, when the completion key is input, and considering the frame to extend in an up-and-down direction or a right-and-left direction and proceeding to the step of outputting the photographic guide screen, when the direction key is input.

  • Publication number: 20070269198
    Abstract: Methods for taking a panoramic photo are disclosed. One method includes the steps of measuring photographing parameters for an object to be photographed and determining if a focal distance of the measured photographing parameters belongs to a preset reference distance. If the focal distance belongs to the preset reference distance, warping a partial edge image of a previously photographed scene onto a photographing plane of a scene being photographed as a guide image in photographing of each scene. The method also includes the steps of displaying the warped image on a preview screen, and photographing a plurality of scenes constituting the panoramic photo by using the measured photographing parameters according to a user's operation.
