Problems solved by technology

In the process of taking a document, when the user wants to take a picture in the landscape orientation, because the user may make the top of the phone higher than the bottom when holding the phone, and the user does not notice it, the phone detects that the document is taken in the portrait orientation. The document photo taken does not meet the user's requirements; or, the user may want to capture the document in portrait orientation, but the user may hold the phone with the left side higher than the right side or the right side higher than the left side without the user noticing , so that the mobile phone detects that the document is taken in the landscape orientation, and the document photo taken does not meet the user's requirements.

Abstract

The invention discloses a method and a device for adjusting the photographing direction, belonging to the communication field. The method includes: the mobile terminal activates the rear camera and enters the photographing mode; determines that the mobile terminal is in a horizontal posture, activates the front camera of the mobile terminal to obtain the user's face image; extracts the first face image from the face image A feature point, a second feature point and a third feature point; according to the first feature point, the second feature point and the third feature point, the current photographing direction of the rear camera of the mobile terminal is adjusted to the target Photo direction. The device includes: a starting module, an extracting module and an adjusting module. By determining whether the current photographing direction of the terminal is the target photographing direction of the user, the present invention ensures that the photographing direction of the mobile terminal is consistent with the user's requirement, and also ensures that the photographing direction of the terminal is consistent with the user's reading direction.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method and device for adjusting the direction of photographing. Background technique [0002] At present, many terminals have a camera function. Due to the continuous improvement of hardware such as a camera of the terminal, the effect of taking pictures is getting better and better, so that users often use the camera function of the terminal to take various photos. For example, a mobile phone is a terminal with a camera function, and users often use the camera function of the mobile phone to take various photos. [0003] At present, a user can use a mobile phone to take pictures of a document. When taking pictures, the mobile phone is usually placed horizontally or approximately horizontally to take pictures of the horizontally placed document. In the process of taking a document, when the user wants to take a picture in the landscape orientation, because the user may make the t...
