Image Quality Determines Differences in Reading Performance and Perceived ImageQuality with CRT and Hard-Copy Displays

摘要

The effects of physical image quality on reading and on perceived image qualityfrom CRT and hard copy displays (photographs) were studied. The results showed that as the image quality of a display increased, indicated by an increase in the value of the modulation transfer function area (MTFA), the reading speed and subjective image quality ratings increased. This change in reading speed and perceived image quality occurred similarly for both-copy and soft-copy conditions. If the image qualities of the displayed text are similar, hard-copy and soft-copy displays will yield equivalent reading speeds.
