Problems solved by technology

In the current technology, the blur effect makes the complex background blurred, so that the subject of the shot is more prominent
The blurring processing of the image by the current technology will reduce the brightness of the highlighted area. The blurring effect is too different from the effect taken by a professional camera, and the user experience is poor.

Abstract

The invention relates to the technical field of image processing, and provides an image blurring processing method and device. The method comprises the following steps: determining a first part of pixels in a to-be-processed image according to a pixel value adjustment threshold of the to-be-processed image, wherein the pixel value of the first part of pixels is greater than the pixel value adjustment threshold of the to-be-processed image; performing first processing on all pixels of the to-be-processed image so as to increase the pixel value of the first part of pixels; performing fuzzy processing on all pixels of the to-be-processed image after the first processing; and performing second processing corresponding to the first processing on all pixels of the to-be-processed image after thefuzzy processing, so that the pixel values of the first part of pixels after the fuzzy processing are reduced, and an image after the blurring processing of the to-be-processed image is obtained. According to the method, the brightness loss of the high-brightness region of the to-be-processed picture in the fuzzy processing process can be effectively reduced, so that the blurring effect of the image is improved.

Description

technical field [0001] The present invention generally relates to the technical field of image processing, and in particular to an image blurring processing method and device. Background technique [0002] With the improvement of people's living standards and the development of science and technology, the use of electronic devices such as mobile terminals has become more and more popular, and users have higher and higher requirements for the shooting functions of electronic devices. [0003] The electronic equipment is equipped with a high-performance camera, making its shooting effect closer to that of professional shooting equipment. At the same time, the captured images also need to be further processed in the later stage. In the current technology, the blurring effect makes the complex background blurred, so that the subject of the photo is more prominent. The blurring processing of the image by the current technology will reduce the brightness of the highlighted area....
