Method of determining an exposure for use in an image forming apparatus |
摘要 |
Utilizing fuzzy theory, the exposure is determined based on an exposure operational formula defined for each of a plurality of previously classified patterns of a color original image. The color original image is divided into a multiplicity of portions for photometric purposes and, for the resulting photometric data, a plurality of features are evaluated. Utilizing fuzzy theory, a coincidence factor with a judging condition for judging the magnitude of the feature value is evaluated for each of the feature values. A coincidence factor for the pattern is evaluated from those coincidence factors to determine a weight for the pattern. Using this weight, a weighted mean of the exposures which is determined from the exposure operational formula is calculated to obtain a specific exposure.
