Abstract

Two hardware factors contributing to the overall image quality of digital CR Ts are display resolution and addressability. The relationship between these two factors and human performance was modeled by a metric of display quality, the Resolution Addressability Ratio (RAR), and investigated within the contexts of Word-Processing (WP) and Computer-Aided-Drafting (CAD) tasks. The findings indicate a perceptual limit to MTF bandwidth improvements, and significant differences iii display quality requirements between the two applications. The regression of image quality as a function of RAR metric values resulted in an r2 = 0.94 for the WP task and an r2 = 0.79 for the CAD task. These findings are discussed in terms of engineering guidelines for the design of CRT and flat-panel displays for applications which vary by the amount of the density of information in their typical displays.
