90 results about "Binocular disparity" patented technology

Binocular disparity refers to the difference in image location of an object seen by the left and right eyes, resulting from the eyes’ horizontal separation (parallax). The brain uses binocular disparity to extract depth information from the two-dimensional retinal images in stereopsis. In computer vision, binocular disparity refers to the difference in coordinates of similar features within two stereo images.

Mobile terminal and method for controlling operation of the mobile terminal

A mobile terminal and a method for controlling the operation of the mobile terminal are provided. In the method, a stereoscopic 3D image that utilizes binocular disparity between a left-eye image and a right-eye image is displayed on a display and a stereoscopic 3D pointer is displayed in the stereoscopic 3D image when a user's hand is detected according to analysis of visual data acquired by a camera. The position of the stereoscopic 3D pointer is moved according to movement of the hand when the movement of the hand is detected according to analysis of the visual data.
