The designer of a display system for continuous-tone
images seeks to make a display that allows viewing at

such as aliasing or visible scan-line or pixel structure.
Picture size, viewing distance, spot profile, and scan-line

profile is the parameter available for optimization.
On page 45, I demonstrated the difference between
a box profile and a Gaussian profile. Figures 5.3 and 5.4
showed that some overlap ...
