Problems solved by technology

[0004] However, before background blurring, it is first necessary to detect the skin color area of ​​the portrait to identify the background area. In the prior art, a skin color detection algorithm is usually used for detection, but in this skin color detection algorithm, a fixed skin color threshold is set. For detection, the fixed skin color threshold is not applicable to every image. For example, for a black image and a white image, if the same skin color threshold is set, the correct skin color area cannot be detected, thereby reducing the The accuracy of skin color detection, thereby reducing the image blur effect

Abstract

Embodiments of the invention disclose an image blurring method and terminal. The method includes the steps of acquiring a target image; determining a skin color range threshold of the target image; determining a skin color region of the target image according to the skin color range threshold; and subjecting a non skin color region other than the skin color region in the target image to blurring processing. The accuracy of the skin color detection can be increased, and thus the image blurring effect is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image blurring method and a terminal thereof. Background technique [0002] With the development of the mobile Internet and the continuous improvement of mobile phone shooting performance, there are more and more demands for taking pictures, and the requirements for the captured images are also getting higher and higher. [0003] When taking pictures, users generally focus on the subject of interest, especially when shooting portraits, the background blur effect is very popular, in this effect, the subject itself is enhanced, while the background part becomes Vague. [0004] However, before background blurring, it is first necessary to detect the skin color area of ​​the portrait to identify the background area. In the prior art, a skin color detection algorithm is usually used for detection, but in this skin color detection algorithm, a fixed skin color thre...
