Method for determining and loading an image-dependent look-up table for generating an enhanced image representation |
摘要 |
A scanner generates a first set of M-bit signals representing an image in a document. A default table translates the M-bit signals into linearized N-bit signals where M>N. A color image processing module processes the N-bit signals to generate an image-dependent look-up table which, thereafter, is loaded into the scanner. The scanner then generates a second set of M-bit signals using a high resolution re-scan of the same image. The second set of M-bit signals are translated into N-bit signals using the image-dependent look-up table to generate an electronic representation with enhancement characteristics.
