A digital picture processing system digitizes and stores the digitized photographic film picture (421) in their captured orientation on film, in order to obviate the need to physically rotate the film scanner relative to the film for vertical pictures, thereby significantly reducing the complexity and cost of the scanner. Instead, each stored picture file (421) has an associated presentation control file (422), which contains orientation and aspect ratio information, so that the picture playback device will know how each picture has been stored on the digital picture database, such as a compact disc. When the disc is inserted into a playback device for driving an output display such as a color TV monitor, the playback device is readily able to decode the playback control information in the course of reading out the digitized picture, so that the picture will be displayed in an upright orientation and at the correct aspect ratio for the display. |
