Digital/ luminance optical image projection method having two optical path processing covering higher/lower luminance dynamic range separately and outputs screen superimposed.

摘要

The luminous signal digital signal conversion has colour coordinates coded in digital bits corresponding to luminance values. The processing has two outputs one for a high luminance dynamic range (0-Lmax1) and the second for a lower luminance dynamic range (0-Lmax2). The two signals are then superimposed on the screen.
