Abstract

The embodiment of the invention provides a photographing method and a mobile terminal. The method is applied to the mobile terminal. A molecular sensor is configured in the mobile terminal. The methodcomprises driving the molecular sensor to emit near-infrared light to a target user, wherein the molecular sensor receives grease characteristic light reflected by the target user; detecting the grease information on the face of the target user according to the grease characteristic light; performing a light supplement operation on the target user; and photographing the target user to obtain thetarget image data. The method adaptively performs flash operations and photographing operations, can start a flash lamp to supplement light when close-range photographing operations, such as selfie orthe like, are performed in some dark environments in order to adapt to the light supplement on the face, thereby ensuring the proper close shot brightness and the background details, solving a problem that greasy parts strongly reflect light and shine, and improving image data quality.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for taking pictures and a mobile terminal. Background technique [0002] With the rapid development of mobile communication technology, mobile terminals such as mobile phones, tablet computers and PDAs (Personal Digital Assistants) have been widely used in learning, entertainment, work, etc., and play an increasingly important role in people's daily life. important role. [0003] Since the mobile terminals are easy to carry and most of them are equipped with cameras, taking pictures has become one of the necessary functions of the mobile terminals. [0004] Users generally need to turn on the flash to supplement the brightness when taking pictures in a relatively dim environment. However, if the user's face has a lot of oil, in scenes where the photo taking distance is close, such as selfies, the oily parts will reflect strongly on the flash, resulting in an oil...
