Problems solved by technology

The disadvantage of this solution is that the relevant hardware modules of the ISP need to be started, resulting in high power consumption of the terminal
The other is to integrate the AE algorithm into the camera. The disadvantage of this solution is that since the AE is calculated in the camera, the speed performance of the AE algorithm will decrease accordingly, and the cost of the camera will inevitably increase.

Abstract

The embodiment of the invention discloses an automatic exposure control method. The method comprises the following steps: acquiring a current frame image acquired by a camera module through a lightweight image interface; processing the current frame image to obtain a target exposure parameter of the camera module; and controlling the camera module to acquire a next frame image according to the target exposure parameter. The embodiment of the invention further provides an automatic exposure control device, a terminal and a storage medium.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and relates to, but not limited to, an automatic exposure control method and device, a terminal, and a storage medium. Background technique [0002] In the related art, there are the following schemes for controlling the automatic exposure of the camera: one is to first use the statistical information module in the camera image signal processor (Image Signal Processor, ISP) to perform brightness information statistics, and then call the automatic exposure of the camera ISP. (Auto Exposure, AE) algorithm to control the exposure of the camera. The disadvantage of this solution is that related hardware modules of the ISP need to be started, resulting in high power consumption of the terminal. The other is to integrate the AE algorithm into the camera. The disadvantage of this solution is that since the AE is calculated in the camera, the speed performance of the AE algorithm ...
