Abstract

The invention discloses an image exposure method, a device, camera equipment and a storage medium; the method comprises the following steps: detecting a present shooting scene contains a figure, and extracting the figure contour and the background portion in the present shooting scene according to the depth of field information of the present shooting scene; obtaining a figure face area, and locating a figure body area according to the face area and the figure contour; respectively detecting the face area, body area and background portion brightness, thus obtaining a corresponding first light value, a second light value and a third light value; controlling exposure and shooting respectively according to the first, second and third light values, thus obtaining a corresponding first exposure image, a second exposure image and a third exposure image; fusing the three images with different exposures, thus obtaining the fused object image. The method can enable the whole shooting process to obtain proper exposure compensation, thus obtaining high quality exposure images.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image exposure method, device, imaging equipment, and storage medium. Background technique [0002] When the image is taken or the viewfinder is displayed, controlling the camera to make a reasonable exposure according to the appropriate exposure compensation is a crucial condition for obtaining a high-quality image. Most of the current camera devices (such as mobile terminals) support manual exposure adjustment. Manual exposure adjustment can be done in the following way: the user triggers the camera device to display the exposure bar on the screen by clicking the setting button, and the user slides the cursor in the exposure bar, that is, Exposure compensation can be set during image shooting to achieve the purpose of adjusting the exposure effect. [0003] At present, when an imaging device (such as a mobile terminal) performs exposure processing on an ima...
