A Refocusing Image Processing Method

Abstract

The invention discloses a refocus image processing method, which relates to the technical field of image processing. The method is characterized by comprising the following steps: S1, an image is acquired, and the image is divided into segmentation areas and distance layers; S2, the distance layers are merged, and processed; S3, the segmentation areas belonging to different layers are marked and then processed; and S4, a blank result image is newly built, layers of images are adhesive to the result image, and a result image is further obtained. Through area segmentation on the image, fuzzy processing of different strength degrees is carried out on a background image according to different distances, the background of the result image can be transited more naturally, distortion of the image is not caused, and the original authenticity of the image is ensured; and through image adhesion fusion by the distance layers in a layer-by-layer mode, fuzzy diffusion of the background is not diffused to a foreground, edge effects from the foreground to the background are better, and optical imaging effects are more realized.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a refocusing image processing method. Background technique [0002] With the rapid development of mobile phone camera functions in recent years, consumers' demand for cameras with more powerful functions has gradually increased, and more and more mobile phones and camera functions use dual cameras to improve the quality of photos. Choosing the right focus point is a way to improve the viewing experience of photos. [0003] At present, the methods for selecting the focusing point include: normal focusing method and refocusing method; among them, the normal focusing method is to determine the focusing point in the process of taking photos, which can specifically include: automatic focus, manual focus and multiple focus, etc.; refocusing method It is to determine the focus point after taking a picture, that is, take a picture first and then focus; and the refocusin...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a refocusing image processing method, which solves the problem that the blurring of the edge of the background spreads to the foreground and causes image distortion when the background is blurred by the refocusing method
