Abstract

Digital film scanners have been used in the photographic industry for more than a decade. The existence of digital image data has made possible the use of computer-based scene enhancement algorithms to improve image quality. These algorithms are usually device-dependent, functioning properly only for data generated by one scanner system. The complexity of most enhancement algorithms make them costly to develop, thus device-independent scene enhancement algorithms would be valuable. The computation of mathematical transformations to convert scanner data to a device-independent space is possible. The data created using these transformations should serve as the input for device-independent enhancement algorithms. A study to determine scanner data space transformations was performed. This study evaluated a subset of Operational Characteristics for three film scanners. These scanner characteristics were used to determine transformations to convert between scanner data spaces. These results were used as part of a system prototype to test the performance of scanner data space transformations.
