Abstract

We developed a new method for character generation that makes reading super fine characters (under 5 points) on a flat panel display easy. We removed the jaggy edges of a character image by subdividing the character image dots into the dots which size is one third as small as the original ones. This method is based on two characteristics of the human eye. These characteristics allowed us to map the subdivided value into display sub pixels and adjust the digital counts of sub pixels. We conducted a subjectivity evaluation experiment to evaluate the effectiveness of this method and found that the method is effective.
