Problems solved by technology

[0002] Smartphones set up a flash near the rear camera. When the ambient light is dim, the flash can provide supplementary light for the rear camera. However, when the user takes a selfie through the front camera of the smartphone, the related technology cannot provide supplementary light for the front camera. Fill light, if the user needs to take a selfie when the ambient light is dim, it will lead to poor photo effects

Abstract

The invention relates to a light supplement method and device, and an electronic device. The method comprises the steps of: when a shooting request is received, controlling a first constant current receiving source to increase the current in a first group of backlight lamps so as to enable the first group of backlight lamps to maintain a first flash brightness for a first set time length; when the first time length ends, starting a shutter of a camera; and controlling a second constant current receiving source to increase the current in a second group of backlight lamps so as to enable the second group of backlight lamps to maintain a second flash brightness for a second set time length. According to the technical scheme, the first group of backlight lamps and the second group of backlight lamps are respectively driven in a time sharing mode, the instant flashing capability of the LED backlight lamps is improved, the camera is enabled to have a large field depth effect under a dark environment, and the shooting experience of the user is effectively is improved.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular, to a method and device for supplementing light, and electronic equipment. Background technique [0002] Smartphones set up a flash near the rear camera. When the ambient light is dim, the flash can provide supplementary light for the rear camera. However, when the user takes a selfie through the front camera of the smartphone, the related technology cannot provide supplementary light for the front camera. Fill light, if the user needs to take a selfie when the ambient light is dim, it will lead to poor photo effects. Contents of the invention [0003] In order to overcome the problems existing in the related technologies, the embodiments of the present disclosure provide a method and device for supplementing light, and electronic equipment, which are used to increase the intensity of the instantaneous flickering of the backlight and ensure that the photos taken by ...
