Abstract

The IDS summation model was used to explain the perception of defocused symbols. Twelve different computer-generated words were used as stimulus for sharpness evaluation by a group of observers and the result compared with the model response, obtained by software implementation. The symbol luminance slope was used as a parameter. The correlation coefficient is greater than 0.99.
