Exposure method and device

The embodiment of the invention relates to the field of image processing, in particular relates to an exposure method and device, and aims to solve the problem that a target object cannot be shot in various scenes or exposure parameters are adjusted through a complicated algorithm in the prior art. The exposure method comprises the following steps: if the target object cannot be identified from an image shot based on a first exposure parameter, shooting according to N set exposure parameters to obtain N images to be selected, wherein at least one of the N exposure parameters is different from the first exposure parameter, and N is a positive integer greater than 1; identifying the target object in each image to be selected, and determining the image to be selected where the target object can be identified as a reference image; and replacing the first exposure parameter with the exposure parameter corresponding to the reference image, and shooting based on the exposure parameter corresponding to the reference image. Therefore, the exposure parameters where the target object can be identified are acquired in different scenes by a simple algorithm, and the target object can be shot in various scenes.
