Abstract: The present invention provides a method and apparatus for adjusting stereoscopic image parallax and a stereo camera. The parallax adjusting method includes obtaining a depth range of a current scene. A preset parallax range may also be obtained according to a current viewing condition. Expected camera parameters of the current scene are calculated according to the depth range of the current scene and the preset parallax range. The stereo camera is adjusted according to the expected camera parameters and used to capture preprocessed stereoscopic images. Further, the captured preprocessed stereoscopic images are processed according to the expected camera parameters to make the preprocessed stereoscopic images suitable for being viewed under the current viewing condition. The disclosed method and apparatus can jointly adjust parameters of the stereo camera and captured stereo images to obtain images or videos with a maximum parallax as well as desired display effect under a specified condition.

Abstract: An autostereoscopic three-dimensional (3D) display device and a method for an autostereoscopic 3D display device is provided.

Abstract: The present disclosure provides a 3D interaction method. The 3D display device detects a distance between an operating element and a display screen and checks whether the distance is less than a maximum distance of a 3D image pointed by the operating element protruding out of the display screen. When the distance is less than the maximum protruding distance of the 3D image pointed by the operating element, the 3D display device acquires a viewing distance between a viewer and the display screen. Based on the acquired viewing distance and the distance between the operating element and the display screen, the 3D display device adjusts the parallax of the 3D image pointed by the operating element to cause an actual distance of the 3D image pointed by the operating element protruding out of the display screen equal to the distance between the operating element and the display screen.

Abstract: A wide-angle autostereoscopic three-dimensional (3D) image display method is provided. The method includes tracking a user in an autostereoscopic 3D image viewing state with respect to a display panel including a plurality of display units, obtaining a first distance between the display panel and a spectroscopic unit array including a plurality of spectroscopic units and a first width associated with each spectroscopic unit, and determining a second distance between a viewing position of the user and the display panel. The method also includes determining a width of a display unit combination corresponding to the second distance. Further, the method includes calculating a gray value of each display unit based on the width of the display unit combination and a reference value of the distance between each display unit and an edge of the display unit combination and displaying the 3D image on the display panel.
