Abstract

The invention provides a shooting method and a mobile terminal, and relates to the technical field of the image processing. The method is applied to the mobile terminal comprising a main camera and asecondary camera, and comprises the following steps: acquiring an image group with different exposures acquired by the secondary camera in a process of displaying a preview image acquired by the maincamera in real time on a shooting preview interface, determining a target exposure combination matched with the current shooting environment based on the exposure of each image in the image group; controlling the main camera to execute a shooting operation according to the target exposure if a shooting instruction is received. The exposure corresponding to the current environment can be acquired in real time by continuously acquiring the images corresponding to different exposures, thereby accurately determining the exposure combination suitable for the current environment; the image obtainedthrough shooting can reflect each details in the image after being synthesized, a problem that the image is unsharp since the exposure is deviant is avoided, and the image sharpness is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to a photographing method and a mobile terminal. Background technique [0002] With the continuous development of mobile terminals, the HDR (High-Dynamic Range, high dynamic range) function of the mobile terminal is usually used to take pictures, so that the images obtained by taking pictures become clearer and clearer. [0003] In related technologies, after the mobile terminal detects that the user has turned on the camera function of the mobile terminal, the mobile terminal can adjust the exposure level when taking pictures according to the brightness of the current environment. Multiple RAW (unprocessed) data are acquired, and finally multiple RAW data are synthesized to obtain a synthesized image. [0004] However, there is a deviation in the exposure degree adjusted by the mobile terminal according to the current environment, so that the cl...
