Abstract

The invention discloses an exposure optimization method, which includes: dividing a target screen into regions based on preset division rules to determine several photosensitive areas of the screen; judging whether the photosensitive areas of the screen are effective photosensitive areas; The screen sensitivity corresponding to the effective photosensitive area, and determine the comprehensive sensitivity of the shooting picture corresponding to the effective photosensitive zone based on the screen sensitivity; determine the exposure value of the corresponding shooting picture based on the comprehensive sensitivity, so that Optimizing the exposure of the corresponding shooting picture according to the exposure value. The invention also discloses an exposure optimization device and a computer-readable storage medium. The invention improves the accuracy of the exposure of the shooting picture.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, and in particular, to an exposure optimization method, device and computer-readable storage medium. Background technique [0002] Nowadays, electronic equipment has more and more functions, and the camera function is one of them. The quality of the camera effect is an important indicator for evaluating the quality of electronic equipment. In the case of unsatisfactory lighting conditions, especially in too dim or bright environments, the accuracy of the exposure value of the photographed image will greatly affect the quality of the camera and the user's video experience. [0003] The current general practice is to use the CMOS sensor (CMOS image sensor) in the camera of the electronic device to judge the light intensity of the imaging area, and then to increase or decrease the exposure value of the picture according to the judgment value. However, due to the generality of the ex...
