A Graphical Method for Television Legibility Analysis

Calvin K. Clauer

The legibility of symbols in a television display may be represented by plotting legibility (accuracy-level) contours against logarithmic coordinate scales of vertical and horizontal resolution. Such graphs are very useful in analyzing the relation of legibility to the symbol size and the television system parameters. All legibility data necessary for the analysis were obtained with a 525-line closed-circuit TV system, by an experimental procedure described in the Appendix. The graphical method should also be effective for comparing the effects of other independent display parameters which are suggested.
