Description

Method, device and mobile terminal for taking pictures

technical field

The invention belongs to the technical field of mobile terminals, and in particular relates to a method and device for taking pictures under a mobile terminal.

Background technique

On mobile terminal devices such as smart phones, taking pictures has become an indispensable and important function. However, there are mainly two ways of taking pictures with existing smartphones:

One is to take pictures manually, that is, after the user activates the camera function, the angle and direction of the shooting are artificially controlled.

The second is to take pictures by timing, that is, to set a time (such as 5 seconds or 10 seconds) in advance, and to take pictures automatically when the preset time is reached.

Method 1 still requires human participation after the camera function is activated, which is inconvenient for individuals or couples to take selfies. Method 2: The time setting is difficult to grasp. If the time setting is too long, it is difficult for the user to maintain the posture of taking pictures. If the time setting is too short, the photo may be taken before the user is ready, which will affect the user experience.

In this embodiment, the receiving information for activating the camera-photographing function includes, but not limited to, an instruction for activating the camera-photographing function issued by the user, or trigger information for activating the camera-photographing function generated according to a preset time interval.

In step S102, it is judged whether there is a face image in the image currently captured by the camera, if the judgment result is "yes", then step S103 is executed, otherwise continue to capture images.

Since this embodiment is mainly used for self-portraits of couples or self-portraits of parent-child users, the judging whether there is a face image in the image currently captured by the camera specifically includes:

Judging whether there are two face images in the image currently captured by the camera;

If yes, it is determined whether the distance between the two face images is less than or equal to a preset distance threshold, and if yes, step S103 is performed.

In this embodiment, it may be judged whether the image captured by the camera contains a face image through face recognition technology.

Preferably, by judging the distance between the face images, the photo is taken only when the distance is less than or equal to the preset distance threshold, which can take more intimate photos for the user and enhance the shooting effect. Wherein, the distance threshold can be modified and set by the user.
