Abstract

The present invention provides a dirt detection method and device. The method comprises periodically reading a focus index FV of a camera module of a terminal, the camera module being at a photographing mode; judging if dirt exists in a camera according to the read FV values; and if yes, sending a prompt message. Through the dirt detection method and device, the problem that dirt on the camera cannot be detected in the prior art is solved, and the effects of detecting the dirt on the camera, timely reminding users and raising user experience are thus achieved.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for detecting dirt. Background technique [0002] At present, the functions of the terminal are becoming more and more perfect, and various functions are loaded on the terminal. In order to meet the increasing needs of people, more and more terminals are equipped with the function of taking pictures and videos. Therefore, people enjoy taking pictures and videos. During the process, removing the dirt on the camera is also essential. The following uses mobile terminals as an example to illustrate. In the field of mobile terminals, the camera function is becoming more and more important. Due to its convenient portability, the use of mobile terminals to take pictures has the potential to replace cameras. However, users will often use mobile terminals to take pictures. It is inevitable to stick grease and other dirt on the lens of the camera, which will affect...
