A transformed DCP has a brighter display luminance than the original DCP, and a display luminance of pure black remains unchanged. By adjusting the PWM, the brightness of a screen display is reduced. To ensure that the transformed DCP has a consistent display luminance with the original DCP, a luminance adjustment consistency mapping model of a local cinema is used to transform a standard PWM level of each frame of the original DCP, to obtain a local PWM level of each frame of the local cinema."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cinema projection method and system","description":"A cinema projection method and system are provided, to perform GDR transformation on an original DCP while keeping a luminance component value of pure black unchanged.
