Method for improving dynamic range of Micro-LED projector system

The invention relates to the field of projection display, and provides a method for improving the dynamic range of a Micro-LED projector system in order to improve the dynamic range of the projector system, which comprises the following steps of: 1, acquiring parameters of the projector system; 2, acquiring brightness distribution of the input image; 3, preprocessing the input image; 4, converting the preprocessed input image into a YCbCr color space; 5, mapping the linear brightness value of the Y component into a nonlinear brightness value, and mapping the linear color difference values of the Cb and Cr components into nonlinear color difference values; 6, performing scaling offset on the YCbCr color space according to the system parameters of the projector; 7, converting the YCbCr color space after zooming and shifting back to the RGB color space; 8, converting the RGB color space into a gray scale signal; and 9, based on the gray-scale signal, using a pulse width modulation method to drive a projector sys
