Embodiment Construction

[0033] As mentioned in the background art, there are various problems in existing attitude angle calculation methods. The attitude calculation method in the existing anti-shake technology mainly uses angular velocity integration, Kalman filter or quaternion method, etc., but the method of angular velocity integration will cause angle offset during long-term calculation, Kalman filter and quaternion method There are problems such as complex algorithms and long calculation time, and the disadvantages of requiring higher performance of the processor.

[0034] The present invention proposes a method that is simple and can quickly and accurately calculate the attitude angle of the mobile terminal, so that ordinary chips can be used to achieve anti-shake of the camera of the mobile terminal, drive the lens to reversely compensate the attitude angle, and improve the problem of blurred pictures .

[0035] The technical solutions in the embodiments of the present application will be c...

Abstract

The invention discloses an attitude angle acquisition method, an anti-shake control method and a mobile terminal. The attitude angle acquisition method comprises the following steps: acquiring angular velocity data and acceleration data; performing angle calculation according to the acceleration data to obtain angle data; and performing complementary filtering processing on the angle data and the angular velocity data through a complementary filter to obtain attitude angles related to the angle data and the angular velocity data. The attitude angle acquisition method is simple, and the attitude angle can be timely and accurately acquired.

Description

technical field [0001] The present application relates to the field of camera anti-shake technology, and in particular to a method for acquiring an attitude angle, an anti-shake control method, and a mobile terminal. Background technique [0002] With the advancement and development of science and technology in modern society, the camera function is becoming more and more popular on mobile terminal devices such as smartphones, and using mobile terminal cameras to take pictures or record videos has become a very common phenomenon in people's daily life. When using the camera of a mobile terminal to shoot, there are still problems that the camera shakes due to human hand shaking or external bumps, which in turn causes the captured image to be blurred and unclear. [0003] How to accurately and timely obtain the attitude angle of the camera caused by external factors during the shooting process, so as to control the movement compensation of the voice coil motor (VCM) lens in th...
