Abstract: A control device sets first points on characters, generates a first frame composed of a first point and first circles, attaches first marks to points at which the first circles intersect characters, detects a range having a largest central angle and no first marks, sets second points on the first circles in the detected region, generates a second frame composed of a second point and second circles, attaches second marks to points at which the second circles intersect characters, sets a direction passing through the center portions of ranges having no second marks and the second point, sets second points arranged in the direction as the same class, calculates an approximate line connecting second points for each class, obtains straight lines indicating a row direction of characters immediately above and below an approximate line, and determines an inclination angle of an image from inclinations of the straight lines.

Abstract: An image processing apparatus includes a character recognizing unit and a font type determining unit. The character recognizing unit is configured to determine a character code of a character in a text of a predetermined process unit in an image. The font type determining unit is configured to determine a font type of the character. Further, the font type determining unit performs a font type determining process; and in the font type determining process, (a) determines a font type on a character by character basis and (b) sets as a specific font type font types of all characters in a text of the predetermined process unit if a ratio of the number of characters with the specific font type to the number of all characters in the text of the predetermined process unit exceeds a predetermined threshold value.

Abstract: An multifunction peripheral includes a font dictionary data configured to include an italic font and a non-italic font for each character code, a determination method selection unit that selects, from a plurality of italic determination methods that are used for italic determination for the character, the italic determination method that is associated with the character code that has been acquired, an italic determination unit that determines whether or not the character in the image data is italic using the italic determination method that has been selected by the determination method selection unit, and a font specifying unit that specifies a font of the character by checking the character that has been determined to be italic by the italic determination unit only with the italic font and checking the character that has been determined to be non-italic only with the non-italic font.
