Abstract

The invention discloses a picture processing method and device, comprising: acquiring a first picture; acquiring the color value of each pixel in the first picture; determining the color value of each pixel in the first picture according to the color value of each pixel in the first picture The rate of change of the color value of the first picture; if the rate of change does not exceed a predetermined threshold, a second picture is obtained, and the second picture is a picture with a color transparency of 100% and a specific graphic; the The high-contrast color value corresponding to the color value of each pixel point of the first picture is determined as the color value of each pixel point of the specific figure in the second picture; rendering the specific figure in the second picture, Get the third picture.

Description

technical field [0001] The invention relates to data processing technology, in particular to a picture processing method and device. Background technique [0002] The existing image watermark generation methods all generate a color with a single color value as the color of the entire image watermark. In the face of pictures of various types and colors, it is inevitable that the color of the picture is highly consistent with the color of the watermark, and the watermark is not obvious and difficult to read, which affects the display effect of the watermark and affects the user's protection of the picture data. Contents of the invention [0003] The present invention provides an image processing method and device to at least solve the above technical problems existing in the prior art. [0004] One aspect of the present invention provides an image processing method, including: [0005] Get the first picture; [0006] Acquiring the color value of each pixel in the first pi...
