Stereo viewing

The invention relates to creating and viewing stereo images, for example stereo video images, also called 3D video. At least three camera sources with overlapping fields of view are used to capture a scene so that an area of the scene is covered by at least three cameras. At the viewer, a camera pair is chosen from the multiple cameras to create a stereo camera pair that best matches the location of the eyes of the user if they were located at the place of the camera sources. That is, a camera pair is chosen so that the disparity created by the camera sources resembles the disparity that the user's eyes would have at that location. If the user tilts his head, or the view orientation is otherwise altered, a new pair can be formed, for example by switching the other camera. The viewer device then forms the images of the video frames for the left and right eyes by picking the best sources for each area of each image for realistic stereo disparity.

An aerial image display device includes an image display unit to display an image; an aerial image formation optical system to cause diffuse light emitted from the image display unit to form an image again in a different space by reflecting the light multiple times and allowing the light to pass through; and processing circuitry to acquire viewpoint position information on an observer viewing a point where the diffuse light is caused to form the image again by the aerial image formation optical system, and to control the image from the image display unit depending on an angle formed by a straight line connecting an end point of a retroreflective sheet and an eye of the observer and a straight line extending from the eye of the observer and reaching the retroreflective sheet right in front.

ADJUSTMENT DEVICE AND METHOD OF OPERATING THE SAME
20230036762 · 2023-02-02 ·

An adjustment device includes a wearable electronic device and a case in which the wearable electronic device is disposed (e.g., seated). The wearable electronic device includes displays (e.g., display apparatuses) which display virtual images for a left eye and a right eye of a user, screen display portions which transmit light sources generated by the displays to the left eye and the right eye, and eye tracking cameras for the left eye and the right eye. The case includes a stator which fixes the wearable electronic device, and a focal lens which is disposed within an eye relief of the fixed wearable electronic device and forms each of images of the virtual images output from the screen display portions of the wearable electronic device on a portion of the case.

Non-uniform stereo rendering

Examples of the disclosure describe systems and methods for recording augmented reality and mixed reality experiences. In an example method, an image of a real environment is received via a camera of a wearable head device. A pose of the wearable head device is estimated, and a first image of a virtual environment is generated based on the pose. A second image of the virtual environment is generated based on the pose, wherein the second image of the virtual environment comprises a larger field of view than a field of view of the first image of the virtual environment. A combined image is generated based on the second image of the virtual environment and the image of the real environment.

IMMERSIVE DISPLAY AND METHOD OF OPERATING IMMERSIVE DISPLAY FOR REAL-WORLD OBJECT ALERT

An immersive display and a method of operating the immersive display to provide information relating to an object. The method includes receiving information from an input device of the immersive display or coupled to the immersive display, detecting an object based on the information received from the input device, and displaying a representation of the object on images displayed on a display of the immersive display such that attributes of the representation distinguish the representation from the images displayed on the display, wherein the representation is displayed at a location on the display that corresponds with a location of the object.
