Title:
FLASHLIGHT BRIGHTNESS COMPENSATION METHOD, UNMANNED AERIAL VEHICLE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/084806
Kind Code:
A1
Abstract:
Provided is a flashlight brightness compensation method. The method comprises: generating a brightness compensation signal according to an actual exposure time of a camera device, and controlling, by means of the brightness compensation signal, a flashlight, such that same performs brightness compensation during photographing, wherein the time of the brightness compensation signal is less than an exposure cycle of the camera device, the exposure cycle comprises the actual exposure time, and the actual exposure time is the time from the start of actual exposure to the end of actual exposure. According to the embodiments of the present disclosure, by means of turning on the flashlight before an exposure signal is turned on and turning off the flashlight after the exposure signal is turned off, the power consumption can be reduced without worsening the light compensation effect at the same time.
