A Refocusing Image Processing Method

Abstract

The invention discloses a refocusing image processing method, which relates to the technical field of image processing. It is characterized in that: it includes the following steps: S1, obtain an image, and divide the image into segmented areas and distance layers; S2, merge the distance layers, and process it; S3, mark the segmented areas belonging to different layers, and then process them; S4, create a new blank result image, paste the layer-by-layer images onto the result image, and then obtain the result image. By segmenting the image area, the background image is blurred to different degrees according to different distances, which can make the resulting image background transition more natural, without causing distortion of the image, and ensuring the original authenticity of the image; at the same time, through The texture fusion of the distance layer layer by layer prevents the blurred diffusion of the background from spreading into the foreground, making the edge effect from the foreground to the background better and more consistent with the effect of optical imaging.

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
