ABSTRACT:
A digital image processing system digitizes and stores photographic film images in their captured orientation on film, in order to obviate the need to physically rotate the film scanner relative to the film for vertical images, thereby significantly reducing the complexity and cost of the scanner. Instead, each stored image file has an associated presentation control file, which contains orientation and aspect ratio information, so that the image playback device will know how each image has been stored on the digital image 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 image, so that the image will be displayed in an upright orientation and at the correct aspect ratio for the display.
