Abstract
A method of determining the position of a particular frame on a film being moved in its longitudinal direction, the film having blip marks provided thereon for respective frames in advance. In this method, no detection of blip marks is effected during a period of time which begins immediately after the leading end edge of a blip mark has been detected and which ends slightly before the time at which the leading end edge of a subsequent blip mark is expected to be detected. Accordingly, there is no fear of dust attached to the film being misjudged to be a blip mark. Also disclosed is an apparatus which may suitably be employed to carry out the above-described method.
