ABSTRACT:
A method of determining an inclination angle of a rectangular image frame read by a microfilm reader at high accuracy. The method is characterized in that the inclination angle of the bottom side line of the image frame is detected to determine the inclination angle of the image. In a preferred embodiment, the bottom side line is discriminated by comparing the projected lengths of the two side lines opposing to the bottom side of the display screen of the microfilm reader, and the side line having the projected length greater than the projected length of the other side line is discriminated as the bottom side line of the image frame.
