The present invention relates to a character recognition equipment which is capable of recognizing with high accuracy those characters that have poor contrast and produce variation in printing density such as characters printed on industrial products. The character recognition equipment according to the present invention is composed of an input unit group which processes in image in a plurality of window regions that are set on a character image, a feature unit group which performs calculation on values obtained by adding thresholds to the output values therefrom, and an output unit group which performs calculation on values obtained by multiplying output values from the feature unit group and adding the thresholds to the sum total thereof. Here, the thresholds and the weights can be adjusted automatically with an actual object image.
