2010 ITE Technical Report  
Wb are investigating display technologies for a Super Hi − Vision system . We have already developed a high − dYnamic −range projector that features dual 皿 odulation of light , which has 7680× 4320 pixels and extrelnely high dynamic range of about ' 1. 1 − million to l. We conducted a subjective evaluation to examine the . degradation of image quality due to the limited dynamic range of a display by using the high − dyIlamic −range projector . The results indicate that the dynamic range of at
