Abstract

The invention discloses a lateral shooting angle detecting method, which is used for detecting the lateral shooting angle of a mobile phone. The method comprises the following steps of: setting an x axis, a y axis and a z axis which form a three-dimensional coordinate system on the mobile phone, wherein a plane formed by the x axis and the y axis is parallel to a plane on which a display screen of the mobile phone is positioned, and the y axis and gravity acceleration g are on the same straight line when the mobile phone held by a user is placed vertical to the ground; sensing gravity acceleration component Ax of the gravity acceleration g on the x axis; acquiring a lateral deflection angle theta according to the gravity acceleration g and the gravity acceleration component Ax; and prompting the deflection angle theta to the user. The invention further discloses an inclined shooting angle detecting method and the mobile phone. In the lateral shooting angle detecting method, the inclined shooting angle detecting method and the mobile phone, the shooting angle is prevented from generating deviations by detecting the lateral deflection angel of the mobile phone and prompting the user to adjust the angle, so that a better shooting effect is achieved, and user experience is increased.

Description

technical field

[0001] The invention relates to the technical field of mobile phones, in particular to a method for detecting a lateral shooting angle, a method for detecting an oblique shooting angle, and a mobile phone. Background technique

[0002] Mobile phones are becoming more and more popular in people's daily life. As a major multimedia device of mobile phones, the camera can take pictures, video and other actions. In addition, during video calls, the camera can be used to have face-to-face conversations with the caller in real time. Because the mobile phone is convenient to carry and use, and users can use the camera in the mobile phone to take pictures at any time in life, travel, work and study, more users will tend to use the shooting function of the mobile phone.

[0003] However, in the process of shooting with the mobile phone camera of the prior art, there are often deviations in the angles of the photos or videos taken, which affects the shooting effect. For...
