文摘

Text legibility is assessed under glance-like reading conditions using psychophysical methods. Text size, contrast polarity, and ambient illumination are compared. Legibility is globally enhanced under daylight-like illumination. Under dark illumination, white-on-black text suffers a legibility disadvantage. This disadvantage is more pronounced as text size decreases.
