Abstract
Each row of characters is extracted from document data representing rows of characters by a character row extracting circuit. The characters are separated from the row by a character separating circuit. In a reference line detecting circuit two histograms are formed, one pertaining to the upper sides of the rectangles bordering the extremities of the characters, and the other pertaining to the lower sides of these rectangles. Two reference lines are defined from the histogram. The characters are sorted intoseveral categories, in accordance with their sizes and the positions they take with respect to the reference lines. The pattern of each character is compared with the dictionary patterns of the same category.
