Problems solved by technology

[0002] When using a camera to take pictures, it is usually checked whether the function of the camera is intact, whether it can be used for imaging, whether the camera is blocked, and whether it can receive light. However, sometimes there is dirt on the camera, and the camera Although it can receive light, dirt can negatively affect the image quality of the camera, and the user may not be aware of this

Abstract

The invention discloses an image processing method. The image processing method provided by the embodiment of the invention comprises the following steps: acquiring preview images of a plurality of different scenes; detecting continuously distributed low-brightness areas with brightness values lower than those of other areas in each preview image; and when the overlap ratio of the low-brightness areas of the preview images is higher than a preset threshold, generating prompt information that the lens is dirty. The invention further provides a terminal and a computer readable storage medium. According to the method, the low-brightness areas in the preview images are detected, if the overlap ratio of the low-brightness areas in the preview images is higher than the preset threshold value, itis judged that the light of the low-brightness areas is formed due to dirt shielding, and at the moment, prompt information that dirt exists in a lens is generated to inform a user.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image processing method, a terminal, and a computer-readable storage medium. Background technique [0002] When using a camera to take pictures, it is usually checked whether the function of the camera is intact, whether it can be used for imaging, whether the camera is blocked, and whether it can receive light. However, sometimes there is dirt on the camera, and the camera Although it can receive light, dirt can negatively affect the image quality of the camera, and the user may not be aware of this. Contents of the invention [0003] Embodiments of the present application provide an image processing method, a terminal, and a computer-readable storage medium. [0004] The image processing method of the embodiment of the present application includes: acquiring multiple preview images of different scenes; detecting low-brightness areas in each of the p...
