Abstract

The invention discloses an image superposition method, an image superposition device, and electronic equipment. The image superposition method comprises the steps of: converting a first image in a first format into a third image and a fourth image, wherein the third image is a color component image in a second format, and the fourth image is a transparent component image in the second format; andsuperposing the color component image, the transparent component image and a second image in a second format to generate a superposed target image. According to the image superposition method and theimage superposition device, the superposition of images can be realized by using fewer computing resources, and the computing resources are saved.

Description

technical field

[0001] The present invention relates to the technical field of image processing, in particular to an image superimposition method and device, and electronic equipment. Background technique

[0002] In order to identify video content, adding a logo to video images has been widely used in industries such as broadcasting and television. At present, the superposition of the station logo image and the video image is realized through CPU processing. The processing process is generally to first convert the video image in the NV12 format to the video image in the YUV format, and convert the station logo image in the BMP format to the AYUV format. Station logo image, the video image of converted YUV format and the station logo image of AYUV format are synthesized into a superimposed image in YUV format, and finally the superimposed image in YUV format is converted into a superimposed video image in NV12 format; the above-mentioned processing process is relatively comp...
