Abstract
A film containing first sections with narrower panoramic frames and second sections with wider normal frames is scanned to obtain density values. To distinguish the panoramic frames from the normal frames, the density values along two longitudinally extending strips near the edges of the film are checked for each film section. Each strip has a length equal to that of the respective frame, and the strips border the narrower panoramic frames but are located within the wider normal frames. The density distribution in each strip is compared with density distributions previously derived from the borders of panoramic frames.
