Abstract

The invention discloses an exposure adjustment method and a mobile terminal. The exposure adjustment method includes: obtaining depth of field information of a preview image collected by a camera, and the depth of field information includes the correspondence between the depth of field and weight of each block in the preview image relationship; obtain the depth of field of the focus block of the preview image; generate the dynamic metering weight of each block according to the depth of field information and the depth of field of the focus block; according to the dynamic metering of each block Adjusting the exposure value of the preview image by adjusting the weight and the image brightness of the preview image can achieve more accurate light metering, so that the exposure of different scenes can better meet user needs, so as to improve user experience.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an exposure adjustment method and a mobile terminal. Background technique [0002] With the popularization of mobile devices, more and more camera functions are used on mobile devices, which has gradually replaced the card machine era. At the same time, users have higher and higher requirements for the quality of camera imaging. Due to the limitations of the characteristics of mobile devices, it is currently impossible to achieve good optical zoom, and the size of the aperture can be adjusted at any time. Due to the limitations of these hardware, if there is a good side image quality, equipment manufacturers can only conduct endless exploration on software algorithms, looking for a way to make up for the lack of hardware. [0003] Generally speaking, in terms of exposure, accurate exposure lays a foundation for the entire photo, and the premis...
