Problems solved by technology

[0004] However, image processing is used for automatic exposure control, and the speed to achieve proper exposure is slow, and exposure errors are prone to occur. Using a light sensor for automatic exposure control, when the orientation of the camera and the sensor is different, the exposure accuracy is low

Abstract

The embodiment of the invention discloses an exposure control method, a terminal and a storage medium. The method comprises the following steps: obtaining current scene information; evaluating the ambient brightness according to the current scene information to obtain the current ambient brightness; when a shooting function is started, acquiring a relative posture with a light source, and determining exposure control information according to the current ambient brightness and the relative posture; and performing exposure control according to the exposure control information during image shooting.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to an exposure control method, a terminal, and a storage medium. Background technique [0002] Automatic exposure control (Auto Exposure Control, AEC), that is, the imaging device automatically adjusts the exposure according to the intensity of light to prevent overexposure or underexposure. [0003] At present, there are two main methods of automatic exposure control. One depends on image processing, which needs to be carried out after the camera is turned on. Through image analysis, the exposure is gradually adjusted. The other is to obtain the ambient brightness in advance through a specific light sensor to control the exposure. . [0004] However, using image processing for automatic exposure control is slow to achieve proper exposure and is prone to exposure errors. Using a light sensor for automatic exposure control, when the orientat...
