PROBLEM TO BE SOLVED: To prevent areas from being not inspected at joints when images of a film running on a conveyor are divided for each inspection. SOLUTION: A method for inspecting a film running on a conveyor includes a process of imaging the film; a process for digitizing the picked up images to obtain image data; a means for writing the image data in a temporary storage means by means of first system clocks; and a process for reading the image data (N) for each inspection from the temporary storage means by means of second system clocks in such a way that adjacent inspection units (N-1, N) overlap for a certain period (50) during which the data are invalidated by an inspection process. The frequency of the second system clocks is higher than the frequency of the first system clocks. COPYRIGHT: (C)2008,JPO&INPIT
