Abstract

The embodiment of the invention provides a lens smudginess detection method and electronic equipment, the method is applied to the electronic equipment, the electronic equipment comprises a lens, and the method comprises the following steps: determining a first distance between the lens and an obstacle; and if the first distance is smaller than or equal to a preset distance, prompting a user that the lens is polluted. In the embodiment of the invention, the first distance between the lens and the obstacle is acquired, whether the surface of the lens is dirty or not is judged in an auxiliary manner according to the first distance, and a user is prompted whether the lens is polluted or not according to the dirty condition of the lens, so that the user can perform corresponding processing according to the prompt, and the influence on the shooting effect is reduced.

Description

technical field [0001] The present application relates to the field of terminals, and more particularly, to a method and electronic device for lens contamination detection. Background technique [0002] Most electronic devices are equipped with lenses and have the function of taking pictures. However, due to the complex use scenarios, the lenses are usually bare and may come into contact with external objects at any time. There is a high probability of contact and friction with external objects, resulting in the lens being dirty, thus affect the shooting effect. [0003] At present, most of the lens contamination detection technologies judge whether the lens is dirty by comparing and analyzing the image features obtained by electronic equipment. However, the analysis method based on image features has certain errors in judging whether the lens is dirty, which may not accurately identify abnormal image information, and cannot accurately identify whether the lens is dirty, wh...
