AI Technical Summary

Problems solved by technology

The main reason why there is a lot of noise in shadow areas or darker areas is that the exposure dynamic range of the shooting equipment is insufficient, resulting in underexposure of shadow areas or darker areas
At present, image signal processing (Image Signal Processing, ISP) usually uses average noise reduction processing for low-sensitivity photos, which may make the overall exposure of the photo brighter, because the noise in the dark area of ​​the photo is amplified, so the photo after average noise reduction processing There will be incomplete image processing

Abstract

The invention discloses an image processing method. The image processing method comprises the steps of obtaining a target picture; performing brightness detection for the target picture to obtain a target region, wherein the average brightness of the target region is less than or equal to a first preset brightness; obtaining target pixels contained in the target region, wherein the brightness of the target pixels is greater than or equal to a second preset brightness; and carrying out noise reduction treatment for the target pixels. The embodiment of the invention also provides a mobile terminal. By adoption of the embodiment of the image processing method and the mobile terminal, noise reduction treatment can be carried out for noisy points of a dark region in the picture, so that the quality of the picture is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and a mobile terminal. Background technique [0002] When shooting with a shooting device (such as a mobile terminal or camera with a shooting function, etc.), even if the shooting device shoots at a low ISO sensitivity, there will be many shadow areas or darker areas in the captured photos of noise. The main reason why there is a lot of noise in shadow areas or darker areas is that the exposure dynamic range of the shooting equipment is insufficient, resulting in underexposure of shadow areas or darker areas. At present, image signal processing (Image Signal Processing, ISP) usually uses average noise reduction processing for low-sensitivity photos, which may make the overall exposure of the photo brighter, because the noise in the dark area of ​​the photo is amplified, so the photo after average noise reduction processing Incomplete...
