An instrument for evaluating qualities of printed characters is constructed. The instrument assesses a large number of printed images, and calculates statistics for a set of printed patterns. The instrument is composed of a scanner, a mini-computer, and its peripherals. A character is scanned by a vertical grouping of photocells, and is sampled every interval of 0.04mm in horizontal and vertical directions. A video signal is quantized into sixty-four gray levels. The data fed from the scanner are evaluated by a program on the minicomputer. The quantities of evaluation are darkness, strokewidth, noise factor, and centroid deviation of an input pattern. Statistical quantities of evaluated values are calculated. Statistical figures are a mean, the minimum, the maximum, a standard deviation, and a "representative".
