Problems solved by technology

[0005] If the frame rate increase algorithm based on motion compensation is directly used for AR / VR frame rate increase (such as 60Hz to 120Hz), it will introduce a large delay (at least close to 2 frames), which is unacceptable for AR / VR

Abstract

The embodiment of the invention provides an image frame prediction method and a device as well as avatar display equipment. The image frame prediction method comprises the following steps: performinginterframe motion vector calculation on two adjacent source frames, so that a frame motion vector of the two adjacent source frames is obtained, wherein the source frames are rendered frames; according to at least two frame motion vectors, performing interframe motion vector prediction, so that a predicted value of the frame motion vectors is obtained; and according to the predicted value of the frame motion vectors, processing a source frame the nearest to the predicted value of the frame motion vectors, so that a predicted frame is obtained.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image frame prediction method, device and head display device. Background technique [0002] AR / VR (Augmented Reality / Virtual Reality) products require high resolution, fast frame rate, and low latency. Under certain delay requirements, complex scenes and high frame rates have high requirements for graphics rendering and data transmission, and the huge data processing and rendering tasks require GPU (graphics processing unit), graphics card, AP (application processor) or Wireless data transmission has brought huge technical challenges. [0003] When rendering, if the rendering performance of a certain frame of data is insufficient, such as the graphics content is complex and the rendering time is too long, and the output frame rate is high, the GPU does not render the image in time according to the frame rate for display, and the next frame of data will be displayed. ...
