PROBLEM TO BE SOLVED: To provide equipment, a method, and a program for character recognition which can improve a recognition rate of hand-written letters in documents in which printed characters and hand-written characters mixedly exist. SOLUTION: An image input part 11 creates an input image of a document in which printed characters and hand-written characters mixedly exist, and a binarization part 12 binarizes the input image. A document structure analysis part 14 separates the binarized image into two or more sentence areas based on paragraphs and columns, and blocks them. A character cut-out part 15 performs a character cut-out to each sentence area, character by character. A characteristic amount calculation part 16 calculates a characteristic amount for each sentence area, using a result of a sentence structure analysis and a character cut-out. A characteristic amount accumulation part accumulates the characteristic amount, and finds a separation factor separating printed characters and hand-written characters. A printed and hand-written characters separation part 18 separates printed characters and hand-written characters in the input image and an output image of the document structure analysis part 14 based on the separation factor, and obtains extraction image for each of them.
