A character frame specification device for specifying a character frame in a form comprises: a line segment extracting unit for extracting a line segment corresponding to a character frame from image data in the form; a space table generation unit for calculating a space between two arbitrary vertical lines in each of all combinations in the case where the two arbitrary vertical lines are selected from respective vertical lines of a line segment extracted by the line segment extraction unit and generating a space table indicating the calculated spaces; a vote table generation unit for counting the number of spaces which are the same from among the spaces indicated in the space table, and generating a vote table indicating the total count value for each of the spaces; a space assumption unit for assuming a space whose total number indicated in the vote table is largest as the space of the character frame; a space modification unit for modifying the or each space in a shape pattern of a character frame registered in advance to the space assumed by the space assumption unit; and a specification unit for matching the shape pattern of the character frame whose space is modified by the space modification unit with a pattern of a line segment extracted by the line segment extraction unit and specifying a character frame on the basis of a result of the pattern matching.
