Problems solved by technology

When the ISO is increased, the captured portrait may have a lot of noise, so the degree of noise reduction for the portrait will also be enhanced
When the noise reduction is too strong and the portrait is too bright, there will be problems such as low saturation and color distortion of the captured portrait, and the portrait effect of the backlit scene is poor.

Abstract

The embodiments of the present invention relate to an image processing method, an image processing device, a mobile terminal and a computer readable storage medium. The method includes the following steps that: an image to be processed and depth-of-field information are acquired; when the image to be processed is a backlight image, the face area of the image to be processed is identified, and the image to be processed is divided into a foreground portrait area and a backlight background area according to the face area and the depth-of-field information; and de-fogging processing is performed on the foreground portrait area. With the image processing method, the image processing device, the mobile terminal and the computer readable storage medium of the invention adopted, the saturation of a portrait in the backlight image can be improved, the color distortion of the backlight image can be reduced, and the visual display of a portrait shot in a backlight condition is better.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an image processing method, device, mobile terminal and computer-readable storage medium. Background technique [0002] When an imaging device takes a portrait in a backlit scene, the background is often too bright or the captured portrait is too dark. In order to increase the brightness of the portrait, a common method is to increase the ISO (sensitivity) of the imaging device. When the ISO is increased, the captured portrait may have a lot of noise, so the degree of noise reduction for the portrait will also be enhanced. When the noise reduction is too strong and the portrait is too bright, there will be problems such as low saturation and color distortion of the captured portrait, and the portrait effect of the backlit scene will be poor. Contents of the invention [0003] Embodiments of the present application provide an image processing method, device, mobile ...
