However, in the process of virtual shooting, the MiniLED large screen often has moiré due to factors such as camera shooting angle, focal length, aperture, and the limitations of the LED display screen's own performance. Moiré is a kind of interference fringe caused by the overlap of two grid-like patterns with similar frequencies, which seriously affects the image quality of virtual shooting. Therefore, how to effectively eliminate the moiré of the MiniLED virtual shooting large screen has become an urgent problem to be solved in the industry.
