摘要
A character presence determination system includes a digit image acquiring unit (22) that acquires a determination digit image and character confirmed digit images from an image of the character string containing the characters and an determination digit; an evaluation value calculating unit (23) that calculates character recognition evaluation values representing certainty of the images being a character image; and a character presence determining unit (26) that determines presence or absence of a character in the determination digit based on the character recognition evaluation value of the determination digit image, a character threshold value (T1) for determining that a character is present, a non-character threshold value (T2) for determining that a character is absent, and a threshold value for determination (T3) that has a value between the character threshold value (T1) and the non-character threshold value (T2) and that is calculated from the character recognition evaluation values of the character confirmed digit images.
