Abstract

The invention discloses a picture processing method and device. The method comprises the steps of obtaining a first picture; obtaining a color value of each pixel point in the first picture; determining the change rate of the color value of the first picture according to the color value of each pixel point in the first picture; if the change rate does not exceed the preset threshold value, obtaining a second picture, and the second picture is a picture with the color transparency of 100% and a specific graph; determining the high-contrast color value corresponding to the color value of each pixel point of the first picture as the color value of each pixel point of the specific graph in the second picture; and rendering the specific graph in the second picture to obtain a 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...
