Abstract

The invention discloses an automatic exposure method and an electronic device. The automatic exposure method comprises the following steps: controlling a camera unit to obtain an image with first image brightness according to a first exposure parameter, wherein the image with the first image brightness has first noise and first fuzziness; obtaining second image brightness according to the first image brightness; calculating a first difference value between the second image brightness and the target image brightness; when the first difference value is greater than a preset threshold value, obtaining a second exposure parameter corresponding to the second image brightness according to a first ratio of the target image brightness to the first image brightness, the first noise and the first fuzziness; and controlling the camera unit according to the second exposure parameter to obtain an image with second image brightness.

Description

Technical field[0001]This application relates to an automatic exposure method and an electronic device, and in particular to an automatic exposure that uses the visual brightness of the human eye, the noise and blur of the display screen to adjust the brightness and exposure parameters of the image obtained by the camera unit and displayed on the display screen Method and electronic device.Background technique[0002]The automatic exposure system in the camera unit can change the brightness of the displayed preview image from a default brightness to the target image brightness. When viewing the preview image, the user can see the brightness change process from the default brightness to the target image brightness. In order to improve the user experience, the brightness of the preview image will change to the brightness of the target image in a gradual manner to prevent sudden changes in brightness. In addition, corresponding to different brightness values, the camera unit can search f...
