The invention relates to a display device for representing two-dimensional and/or three-dimensional objects or scenes. The display device comprises at least one illumination device for emitting sufficiently coherent light, at least one spatial light modulation device for modulating incident light, and at least one optical system. The at least one optical system is provided for multiple imaging of the at least one spatial light modulation device and for generating virtual viewing windows in accordance with the number of images of the at least one spatial light modulation device. The individual images of the at least one spatial light modulation device are combined with one another as segments and form a field of view. The field of view comprises at least one high-resolution holographic segment and at least one low-resolution holographic segment.

Process and system for encoding and playback of stereoscopic video sequences

A method for decoding a compressed image stream, the image stream having a plurality of frames, each frame consisting of a merged image including pixels from a left image and pixels from a right image. The method involves the steps of receiving each merged image; changing a clock domain from the original input signal to an internal domain; for each merged image, placing at least two adjacent pixels into an input buffer and interpolating an intermediate pixel, for forming a reconstructed left frame and a reconstructed right frame according to provenance of the adjacent pixels; and reconstructing a stereoscopic image stream from the left and right image frames. The invention also teaches a system for decoding a compressed image stream.

USING CAMERA IMAGE LIGHT INTENSITY TO CONTROL SYSTEM STATE
20210141446 · 2021-05-13 · ·

A method, system, and apparatus provide the ability to control a system state of/in an image viewing application using a camera/portable viewing device. A screen of the camera is used to display a virtual reality view and an opening is positioned over a lens of the camera. The screen and physical buttons of the camera are not accessible when the camera is placed into the virtual reality viewing mechanism. An image is acquired from a camera through the opening. Color is used to make choices for operations. Alternatively, based on the toggling of the system state through a light blocking operation, a motion operation is conducted. The motion operation is based on length of time light is blocked and the length controls a speed of the motion operation.

Field of view expansion by color separation

A display system is presented for displaying a color stereoscopic image comprising first and second images for user's left and right eyes respectively. A first display is configured for displaying first and second color channels of the first image to the left eye, such that a field of view of the first color channel of the first image is offset from a field of view of the second color channel of the first image in a first direction. A second display is configured for displaying first and second color channels of the second image to the right eye, such that a field of view of the first color channel of the second image is offset from a field of view of the second color channel of the second image in a second direction opposite to the first direction.
