A method and apparatus for detecting and processing image information for detecting and reading out information which has been recorded on the marginal portions of a film negative sheet which are outside the image frames thereof. The marginal information is either printed or recorded on another recording medium together with the image information contained within the frames. The marginal information may be used during photographic printing so as to discriminate the front surface from the back surface thereof and/or to discriminate the top surface of the film from the bottom surface of the film.
