Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments It is a part of the embodiments of the present disclosure, but not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present disclosure.

[0031] With the improvement of people's requirements for video quality and the upgrading of electronic products, HDR video applications are becoming more and more common, and more and more electronic products (eg, mobile phones) support HDR video images. Most of the current image videos are SDR videos. Each pixel value channel of an SDR vide...

Abstract

The embodiment of the invention provides a video image processing method and device and an electronic device. The method comprises the steps: obtaining the value of an integer pixel corresponding to a to-be-processed video image and the image bit width, and obtaining a target interpolation formula; based on a parallel processing technology, determining the value of a sub-pixel corresponding to the integer pixel according to the target interpolation formula and the value of the integer pixel, wherein the sum of the absolute value of the target interpolation coefficient in the target interpolation formula and the image bit width is smaller than the parallel processing bit corresponding to the preset low bit width; and encoding the to-be-processed video image according to the value of the integer pixel and the value of the sub-pixel, so that the parallelism of pixel interpolation can be improved, the time required for encoding the video image is reduced, the encoding efficiency of the video image is improved, and the user experience is high.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of video processing, and in particular, to a video image processing method, device, and electronic device. Background technique [0002] With the upgrading of electronic products, high dynamic range (High Dynamic Range, HDR) video image applications are becoming more and more common, compared to standard dynamic range (Standard Dynamic Range, SDR) The pixel value channel of video images is through low bit width (for example , 8 bits (bit)), and the pixel value channel of the Hdr video image is represented by a high bit width (for example, 10bit, 12bit). [0003] Currently, HDR video is often required to be encoded for several reasons (for example, to improve video transmission efficiency). In the process of encoding HDR video, pixel-by-pixel interpolation algorithms are often used for pixel interpolation. However, when the existing sub-pixel interpolation algorithm is used to process...
