| titleOfInvention | How to automatically recreate original scenes from electronically scanned color negative or positive film |
| abstract | PROBLEM TO BE SOLVED: To provide an automatic, electronically scanned color negative film, in which erroneous duplication is avoided and excellent reproduction quality and high accuracy are obtained in the color reversal of a negative film. Or how to duplicate original scenes from positive film. SOLUTION: A gray straight line that optimally approximates a set of points formed by scanned density values of pixels in an RGB color space is obtained, and a minimum transmission value is subtracted from the scanned transmission value, respectively. A corrected transmission value corresponding to the corrected density value is determined, a film exposure value reconstructed from the corrected transmission value is determined, and a logarithmic value of the film exposure and the corrected density value are calculated. The film exposure straight line indicating the relationship is constructed using the gray straight line, and the reconstructed film exposure value is normalized to a fixed highlight point and an image region between the normalized shadow fixed point. The solution is to map and determine a normalized film exposure value. |
