ABSTRACT:
An automatic photographic printer is programmed to determine, from image classification pixel scan data, the existence of panoramic image frames interspersed among full size image frames on a film strip. The printer is initially set to assume all image frames are panoramic images until any one of the following test conditions is found that then indicates the image is not panoramic: (a) an initial pixel value indicates the existence of film density, (b) differences in pixel density values in rows within the non-panoramic areas of the frame indicate the existence of film density or (c) pixel density values on opposite sides of a line separating panoramic from non-panoramic frame areas indicate the absence of a frame edge.
