The Importance of Contrast and its Effect on Image Quality
The impact that contrast has on image quality—both subjectively and quantitatively—with respect to rear projection televisions (RPTVs) is explored as a function of average picture level (APL). Measurements of a DLP™ RPTV and a direct view CRT TV are com-pared in order to understand the importance that total system contrast has on perceived contrast, sharpness, and overall image quality as a function of APL. The response of the human eye to both brightness and contrast (as a function of APL) of the TV images is modeled. The effect of different ambient conditions is also considered, to understand the impact that ambient lighting has on the eye's response and how it affects the perceived contrast performance of the typical RPTV.
