Shooting method and mobile terminal

Abstract

The invention provides a shooting method and a mobile terminal. The method comprises the following steps of: acquiring a facial image of a target object through a camera; obtaining facial feature data in the facial image; judging whether the facial feature data is matched with target expression feature data or not; and executing shooting operation if the facial feature data is matched with the target expression feature data. According to the embodiment of the invention, the facial feature data is obtained; when the facial feature data is matched with the target expression feature data, a shooting shutter button is started automatically and conveniently, so that shooting operation is carried out; the shooting method provided by the invention is more convenient to perform shooting operation; and furthermore, the shooting method can also be used for shooting a photograph having relatively ideal expression.

Description

technical field

[0001] The invention relates to the field of communication technologies, in particular to a photographing method and a mobile terminal. Background technique

[0002] In addition to the basic communication functions of mobile terminals, there is also a shooting function that is more frequently used. Commonly used shooting methods include: manually pressing the shooting shutter button on the shooting preview interface to complete shooting; using a special selfie stick to complete shooting; using voice to complete shooting, and so on. In the above shooting methods, after the person being photographed is ready to take pictures, the shooting shutter button needs to be manually pressed or the shooting shutter button is pressed virtually by voice. Among them, manual pressing of the shooting shutter button requires hands and eyes to perform the pressing action, and voice mode needs to use the mouth to issue voice commands. The above shooting methods are not conduciv...

[0029] see figure 1 , figure 1 is a flow chart of the shooting method provided by the embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0030] Step 101, collect a face image of a target object through the camera.

[0031] In this step, the above-mentioned process of collecting the face image may be that when the user turns on the camera of the mobile terminal, the face image of the target object is collected through the camera on the shooting preview interface. The aforementioned camera may be a front camera or a rear camera. In addition, what the camera collects for the target object is not only a face image, but also other images other than the face image.

[0032] Step 102. Obtain face feature data in the face image.

[0033] In this step, the above-mentioned facial feature data may be feature data formed by coordinate points of N facial feature points representing expressions, wherein N is a positive integer, an...
