Method and Apparatus for Calculating Duty Cycle of Lighting, Terminal, and Storage Medium

Abstract: the present application provides a method and an apparatus for calculating a duty cycle of a lighting, a terminal, and a storage medium. the method includes: determining a first expression formula of a chromaticity coordinate, a luminous flux and an input duty cycle of each path of three paths of a rgb color light source; calibrating, based on the first expression formula and tristimulus values of the three paths of the rgb color light source under a full current operation, a nonlinear transformation of the luminous flux, to obtain a first duty cycle value; and calibrating, based on the first duty cycle value and the first expression formula, a nonlinear transformation of the chromaticity coordinate, to obtain a second duty cycle value; and controlling displaying colors of the rgb color light source based on the second duty cycle value.
