摘要： A special-purpose hardware device for achieving intraframe image processing in head-mounted displays may include an image-correction component that receives a single image frame destined to be displayed for presentation to a user wearing a head-mounted-display system. The image-correction component may also receive user-motion data indicating that the user wearing the head-mounted-display system has made at least one movement since generation of the single image frame. The image-correction component may further perform hardware-accelerated intraframe processing operations on the single image frame in accordance with the user-motion data to compensate for the movement made by the user on a line-by-line basis. In addition, the special-purpose hardware device may include a frame-output interface that feeds the single image frame to a display device of the head-mounted-display system to facilitate displaying the single image frame for presentation to the user. Various other apparatuses, systems, and methods are also disclosed.

摘要： A special-purpose hardware device for mitigating motion-to-photon latency in head-mounted displays may include an image signal processor that receives at least one image frame captured by a camera device of a head-mounted-display system. The special-purpose hardware device may also include an input-formatting component that receives the computer-generated imagery. The special-purpose hardware device may further include a blending component that generates at least one mixed-reality frame by overlaying the computer-generated imagery onto the image frame. The special-purpose hardware device may additionally include a frame-output interface that feeds the mixed-reality frame generated by the blending component to a display device of the head-mounted-display system to facilitate displaying the mixed-reality frame for presentation to a user wearing the head-mounted-display system. Various other apparatuses, systems, and methods are also disclosed.

摘要： Disclosed herein a system, a method and a device for reducing a size and power consumption in encoder and decoder frame buffers using lossy compression. An encoder of a first device can provide a first video frame for encoding, to a prediction loop of the first device. In the prediction loop, lossy compression can be applied to the first video frame to generate a first compressed video frame. In the prediction loop, lossy decompression can be applied to the first compressed video frame. The encoder can provide, to a decoder of a second device to perform decoding, encoded video data corresponding to the first video frame and a configuration of the lossy compression.
