摘要
A digitizer having a dual exposure technique is combined with an associated LUT for each exposure. Each LUT may have a transfer function including a logarithmic operator resulting in a digitized image with improved photometric resolution and increased dynamic range. A digitizer utilizing multiple exposures at approximately equal exposure time intervals provides a noise reduction for lower optical density portions of the data medium further contributing to increased dynamic range. Associated methods are also provided.
