Method and device for filling light during photographing

Abstract

The invention provides a method and device for filling light during photographing for improving the photographing quality of pictures or videos of an intelligent terminal. The method comprises the following steps: whether a part which needs to fill light exists in a current object to be photographed; if the part which needs to fill light exists in the current object to be photographed, then stopping automatic light metering and parameter adjustment operations of a camera module; transmitting a command required for filling light for the part which needs to fill light to a flash adjustment module; and after receiving other parameters and the command by the flash adjustment module, opening a flash to fill light for the part which needs to fill light. The technical scheme of the invention effectively prevents the overall light filling for the object to be photographed and prevents overexposure for some parts of the object to be photographed on one hand; and on the other hand, avoids the underexposure of the part which needs to fill light in the photographing object, so that the photographing quality of the pictures or videos and so on can be improved.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a method and device for supplementary light for photography. Background technique [0002] The development of smart technology has made smart terminals such as smart phones and tablet computers more and more powerful. In addition to basic communication functions, such as calling and sending text messages, listening to music, taking pictures, and playing games have gradually become the main functions of smart terminals. It is no exaggeration to say that smart terminals are already a product that integrates communication and entertainment, especially in terms of taking photos and video recordings. Some smart terminals are comparable to cameras, and have replaced portable digital cameras in most scenarios. function. [0003] In recent years, although the technical level of the camera module of the smart terminal has made great progress, but limited by the size of th...

AI Technical Summary

Problems solved by technology

In such a large light ratio scene, due to the limited latitude of the camera module of the smart terminal, if the light is supplemented mechanically, the subject may be overexposed when the brightness of the subject is much greater than the brightness of the background , but the background may still be underexposed. When the brightness of the subject is much smaller than that of the background, the background may be overexposed, and the subject may still be underexposed. Either way, it will affect the shooting effect

[0004] For the above-mentioned troubles of using smart terminals to shoot, there is currently no good solution in the industry
