Method and device for inhibit AEC jumping and terminal equipment

Abstract

The invention provides a method and device for inhibit AEC jumping and terminal equipment. The method comprises the steps that the current zoom multiple of a camera device is acquired; whether or not the current zoom multiple is in a preset critical range is judged, wherein the critical range comprises the first zoom multiple and the second zoom multiple, and the second zoom multiple is the zoom multiple obtained when a wide-angle lens and a telephoto lens are switched; and if the current zoom multiple is in the critical range, another lens is opened on the basis that one lens is in an opened state, and an AEC value of another lens is converged to be in a stable state in advance. According to the method, due to the fact that the to-be-switched lens can be converged to be in the stable state in advance, the condition that the AEC brightness jumping problem is generated during lens switching is effectively avoided, and the shooting effect and the user experience are improved.

Description

Technical field [0001] The present invention relates to the field of electronic equipment, and in particular to a method and device for inhibiting AEC jump, and terminal equipment. Background technique [0002] With the continuous development of electronic equipment, users have higher and higher requirements for the shooting function of the electronic equipment, and the requirements for automatic exposure control (AEC) of the camera device of the electronic equipment have also increased. When the camera of the current electronic equipment switches the zoom factor, for example, switching from ZOOM 1X to ZOOM 2X, the camera will switch from a wide-angle lens to a telephoto lens. [0003] At the moment of lens switching, since another camera has just started, the camera’s default AEC may not match the current environment's lighting conditions. It is necessary to adjust the AEC according to the environment's lighting conditions. Therefore, at the moment of lens switching, AEC brightnes...
