Abstract

PURPOSE:To read characters with different kinds of character mixed with a high precision, by deciding the category of the input character on a basis of the appearance probability and the error probability of candidate subcategories to output the character code, in the read system for characters with different kinds of character mixed. CONSTITUTION:When the character pattern signal obtained by scanning the form is subjected to recognization processings individually by recognizing parts 30-50 classified by the kind of character and candidate subcategory codes are sent to deciding parts 60-80 which decide the most likely candidate subcategories in individual kinds of character, conditional appearance probability values of candidate subcategories are read from storage parts 90-110 for apperarance probability values in individual kinds of character. The code and the appearance probability value of the candidate subcategory of a maximum value for every deciding part are sent to deciding part 200 for the most likely candidate subcategory among kinds of character. Deciding part 200 reads the conditional error probability value of the most likely candidate subcategory in each kind of character from error probability storage part 280 and appreciates subcategories of a large appearance probability and a small error probability and sends the candidate subcategory code of a large appreciation value to character generatig part 290 to output the character code.
