Abstract

The invention discloses a light supplement method and an image acquisition device, which are used to solve the problem that the image acquisition device in the prior art cannot adjust the light supplement intensity of the supplement light device for different objects to be photographed, resulting in the The technical problem of the poor fill light effect of the shooting object. The light supplement method is applied to an image acquisition device, and the image acquisition device is connected to a light supplement device, and the method includes: when the image acquisition device captures a first image of a first area, obtaining the first The first distance parameter between the object to be photographed in the area and the image acquisition device; based on the corresponding relationship between the distance parameter and the driving current value of the light supplement device, according to the first distance parameter, determine the first driving Current value: drive the supplementary light device with the first driving current to supplement light to the object to be photographed.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a light supplement method and an image acquisition device. Background technique [0002] With the development of computer technology, more and more electronic devices appear in people's lives, such as feature phones, smart phones, tablet computers, smart TVs, digital cameras, etc., which bring more and more possibilities to people's lives. convenience. [0003] At present, in order to meet people's needs, the requirements for image acquisition devices, such as cameras and digital cameras, are increasing day by day. Taking smartphones as an example, since the camera is installed, a supplementary light device, usually a flash, is installed next to the camera, so that the user can supplement the light on the object to achieve better shooting when taking pictures. Effect. Generally, when the user takes a picture of a flower in a dark environment, in order to be able to take a ...
