Video frame processing method, device, equipment and storage medium

Abstract

The embodiment of the present application discloses a video frame processing method, device, device, and storage medium, which belong to the field of computer technology. The method includes: acquiring the bit depth difference between the first bit depth and the second bit depth, wherein, The first bit depth is the bit depth of the display, the second bit depth is the bit depth of the video to be played by the display, and the second bit depth is less than the first bit depth; according to the bit depth difference Acquiring a sharpening filter, the bit depth difference is an integer multiple of m, the m is a logarithm of n with base 2, and the n is the sum of all coefficients in the convolution kernel of the sharpening filter, m≥1 and n≥2; performing convolution operation on each video frame in the video with the convolution kernel of the sharpening filter to obtain the processed video frame. The embodiment of the present application can avoid the problem of color scale contour lines when the bit depth of the video is increased.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a video frame processing method, device, device, and storage medium. Background technique [0002] When a component of a pixel in an image is represented by a binary number, the number of bits in the binary number may be referred to as the bit depth of the image. For example, if a component in a pixel is represented by an 8-bit binary number, the bit depth of the image is 8 bits. Generally, the bit depth can reflect the accuracy of the color scale of the image, and the color scale refers to the index standard of the brightness of the image. For example, if the bit depth of an image is 8 bits, the image has 2 8 color levels, that is, 256 color levels, and each color level corresponds to a brightness. [0003] For a video, the bit depth of the video is equal to the bit depth of each video frame (also called an image) in the video. If the bit de...
