Problems solved by technology

However, when encountering a situation with a large light ratio, such as the photographer facing the sun and the subject facing away from the sun, and the subject’s face is in the shadow at this time, the photos taken may appear to have normal exposure and the subject’s exposure is normal. The subject’s face exposure is underexposed; or the subject’s face exposure is normal, but the environment is overexposed, it is difficult to obtain satisfactory photos for the user, resulting in poor user experience

Abstract

The invention discloses a method, a device and a mobile terminal for adjusting the exposure of a local area, wherein the method for adjusting the exposure of a local area comprises the following steps: under the photographing preview interface, determining the first area in the photographing preview interface, and obtaining the The first exposure data corresponding to the first area; receiving the user's photographing operation, obtaining the second exposure data exposed in the second area; and inserting the first area with the first exposure data into the overall area with the second exposure data , and generate the resulting image. The method, device, and mobile terminal for adjusting local area exposure in the embodiments of the present invention solve the problem of underexposure in a local area under high light ratio conditions, obtain better photo effects, and improve user satisfaction.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method, device and mobile terminal for adjusting local area exposure. Background technique [0002] With the continuous advancement of technology, smart phones have become one of the indispensable communication tools in people's lives. People can install various APPs in smart phones to realize corresponding functions, such as playing music, watching videos, taking pictures, etc. When a user uses a mobile phone to take a photo, he only needs to trigger the camera button to complete the photometry, exposure, and finally photo generation process. However, when encountering a situation with a large light ratio, such as the photographer facing the sun and the subject facing away from the sun, and the subject’s face is in the shadow at this time, the photos taken may appear to have normal exposure and the subject’s exposure is normal. The subject's face is underexpo...
