Problems solved by technology

[0004] For this reason, the present invention proposes a method for accelerating AEC convergence, so as to determine the AEC value corresponding to the target zoom factor according to the brightness information of the environment where the terminal device is located, and solve the problem that the camera starts from the default value when switching the existing zoom factor. Convergence, there is a problem of slow convergence of AEC

Embodiment Construction

[0047] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0048] The following describes the method, device, and terminal device for accelerating AEC convergence according to the embodiments of the present invention with reference to the accompanying drawings.

[0049]At present, the aperture value and shutter speed can be automatically controlled through AEC, and the amount of incoming light can be controlled to adjust the overall brightness of the shooting scene and improve the shooting quality. When switching the zoom factor of the camera, the AEC needs to be adjusted to adjust the a...

Abstract

The present invention proposes a method and device for accelerating AEC convergence, and a terminal device, wherein the method includes: collecting brightness information of the environment where the terminal device is located; obtaining the target zoom factor that the camera device is trying to switch; The target AEC value of . The method collects the illumination conditions of the environment where the terminal device is located in real time, and determines the AEC value corresponding to the target zoom factor according to the collected brightness information, so as to accelerate the AEC convergence when switching the zoom factor, and solve the problem of switching the zoom factor in the prior art. When , the camera starts to converge from the default value, and there is a problem that the convergence speed of AEC is slow.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a method and device for accelerating AEC convergence, and terminal equipment. Background technique [0002] At present, when switching the zoom factor of the camera, or changing the shooting environment of the camera, such as changing from an environment with relatively strong light to an environment with low light, the automatic exposure control (Automatic Exposure Control, AEC) of the camera may appear to flicker , and then gradually darken the situation. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the present invention proposes a method for accelerating AEC convergence, so as to determine the AEC value corresponding to the target zoom factor according to the brightness information of the environment where the terminal device is located, and ...
