Watermark adding method and device and electronic equipment

The invention provides a watermark adding method and device and electronic equipment in the technical field of image processing. The watermark adding method comprises the following steps: carrying outnoise processing on a first watermark in different directions to obtain a plurality of watermark patterns, and carrying out noise processing on the first watermark in different levels in the same direction to obtain one or more of the plurality of watermark patterns; obtaining a first pixel value of a preset area of the multiple watermark styles, and obtaining a second pixel value of a first image to which watermarks are to be added; and superposing the first pixel value and the second pixel value to obtain a plurality of types of second images, the different types of second images includingdifferent watermark patterns. According to a watermark adding scheme provided by the invention, the anti-theft coefficient of the image can be improved. 本公开提供一种添加水印的方法及装置、电子设备；涉及图像处理技术领域。所述添加水印的方法包括：对第一水印进行不同方向的噪声处理获得多种水印样式，以及
