Dot analysis device, dot analysis program storage medium, and dot analysis method

摘要

A dot analysis apparatus includes a dot converging section that converges individual dots forming a dot image toward their respective centers, a selecting section that selects plural dot units each consisting of one main dot and plural sub-dots surrounding the main dot from the converged dots, a calculating section that calculates an interval between the main dot and the sub-dots of each dot unit and a direction of arrangement of the main dot and the sub-dots, and a statistic processing section that determines statistic distributions of the interval and the direction calculated for each dot unit by the calculating section and determines the interval and the direction corresponding to the peaks of their respective distributions as the interval between the regularly arranged dots forming the dot image and the direction of the regular arrangement of the dots forming the dot image, respectively.
