A glasses-type mobile terminal includes a display configured to display a virtual reality image and a controller configured to acquire reality information from a mobile terminal connected to the glasses-type mobile terminal and controlling the virtual reality image if a reality returning time indicating that viewing of the virtual reality image should be finished is reached based on the acquired reality information.

An object of the present invention is to obtain calibration data more easily in a VR (Virtual Reality) device. a user wearing a pair of VR goggles visually recognizes overlapped marker images displayed in the 360-degree VR space, and a stationary state is detected when the images for right and left eyes are overlapped, and when the stationary state satisfies a predetermined condition set in advance, one of the plurality of marker images displayed on the display in this state, which is at the center, is set as a marker image for calibration setting, calibration data of the interpupillary distance based on the marker image for calibration setting having been set is acquired, and the acquired calibration data is set as calibration data used for subsequent reproduction of images.

An image display device includes a processor that sets a location of a virtual image plane on which a virtual image is formed according to depth information included in first image data and generates second image data obtained by correcting the first image data based on the set location of the virtual image plane; an image forming optical system including a display element configured to modulate light to form a display image according to the second image data and a light transfer unit that forms the virtual image on the virtual image plane, the virtual image corresponding to the display image formed by the display element, the light transfer unit comprising a focusing member; and a drive unit that drives the image forming optical system to adjust the location of the virtual image plane.

Apparatus and methods for enhanced 3D visualization includes receiving a plurality of images of an image scene from a plurality of image sensors. Depth information at locations of the image scene is received from a plurality of depth sensors. The depth information is combined with the plurality of images of the image scene using a machine learning model. A 3D representation of the image scene is generated based on the combined depth and image information.

An information processing device (control device) includes a control unit that performs control, during control of display of a virtual space accompanied by viewpoint change, to display a model of the virtual space in a manner changeable to any appearance desired by a user, and to display the virtual space by moving a virtual user viewpoint to a position on the virtual space at which the same appearance as an appearance of the model is obtained.

Methods and systems for depth-based foveated rendering in the display system are disclosed. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. Some embodiments include monitoring eye orientations of a user of a display system based on detected sensor information. A fixation point is determined based on the eye orientations, the fixation point representing a three-dimensional location with respect to a field of view. Location information of virtual objects to present is obtained, with the location information indicating three-dimensional positions of the virtual objects. Resolutions of at least one virtual object is adjusted based on a proximity of the at least one virtual object to the fixation point. The virtual objects are presented to a user by display system with the at least one virtual object being rendered according to the adjusted resolution.

A near eye display system including a display screen, a graphic processing unit, a lens group, a focal length adjustment device, an interpupillary distance adjustment device, a detection unit, and a control unit is provided. Positions of a left-eye image and a right-eye image to be displayed on the display screen may be adjusted based on lateral displacement amounts of a left-eye lens and a right-eye lens, such that centers of the left-eye image and the right-eye image are respectively aligned with centers of the left-eye lens and the right-eye lens. Sizes (magnification) of the left-eye image and the right-eye image to be displayed on the display screen may be adjusted based on longitudinal displacement amounts of the left-eye lens and the right-eye lens, such that sizes of a visual left-eye image and a visual right-eye image seen by a user are identical. Operation methods thereof are also provided.

Provided is an endoscope apparatus provided with: an elongated insertion portion that is inserted into a body; an image-acquisition portion that has an imaging optical system disposed at a distal end of the insertion portion and that acquires two images having parallax for the same imaging subject; an identifying portion that identifies an image of an object, which is in close proximity to the imaging optical system, that is captured only in one of the two images acquired by the image-acquisition portion; and a close-proximity-image-removal processing portion that processes the image so that the image of the object identified by the identifying portion is removed from the image.

Disclosed herein are a method and apparatus for providing a personalized three-dimensional (3D) image. The apparatus for providing a personalized three-dimensional image using convergence matching may include a fixed screen set as a horopter region, a calculation unit configured to calculate a shift value of an image projected onto the screen based on a distance from a virtual stereo camera to a target object, a convergence matching unit configured to match a convergence angle to the horopter region based on the shift value, and a controller configured to control the convergence matching unit to maintain the convergence angle when a user's gaze is shifted to a nearby object having the same depth value as the target object.
