  • Patent number: 5682505
    Abstract: In order to generate an image, modelling data representing image features of the image are stored in a data base, and first characteristics, such as colors, are stored in another data base. An analyzer unit is then able to assign the first characteristics to the image features in an objective way. Subjective properties, e.g. `darker`, `lighter`, are also defined over a range for the image features and a user interface permits a user to select an appropriate value of the subjective property within the range, thereby to generate a second characteristic on the basis of rules relating to the subjective properties stored in a data base. An interpreter unit then modifies the first characteristic on the basis of the second characteristic before the selected image features are rendered into an image by a rendering unit for display by a display unit.
