Abstract
The invention discloses a continuous focalizing system and a method of a mobile phone camera. The continuous focalizing system and the method of the mobile phone camera comprise the following steps: step A, a central processing unit (CPU) judges whether a mobile phone is in a scene change process state at present through a triaxial acceleration sensor, and a step B proceeds if the mobile phone is not in the scene change process state at present; step B, the CPU transmits an automatic focusing order to a camera module through a microprocessor; and step C, the camera module conducts automatic focusing according to the automatic focusing order of the microprocessor. According to the continuous focalizing system and the method of the mobile phone camera, the triaxial acceleration sensor is used to acquire the state of the mobile at present, and the automatic focusing is conducted when the mobile phone is in a static state, so that photographing is achieved; when the mobile phone is in a motion state, focusing is not conducted; and a user does not need to focus manually, so the continuous focalizing system and the method of the mobile phone camera have the advantages of simple operation and good user experience.
