Abstract

A system for selecting decorative materials is based on large numbers of high-resolution, full color images of decorative materials stored in a compressed format on an inexpensive medium such as a CD-ROM. In creating the ROM, each image is coordinated with additional information such as style of pattern, type of material, and other auxiliary information. Before final compression and storage of the image data color information is added by spectrophotometrically analyzing the decorative material. Color values for a background color and up to four foreground colors are determined. Individual colors are then referenced to a comprehensive color standard system containing a large number of standardized color swatches. Spectrophotometric color referencing allows the data records to be rapidly searched on the basis of color, as well as the other information in the record. Wallpaper patterns, drapery material, floor covering, or paint can then be rapidly selected on the basis of matching color. Various patterns and paints can be compared side by side on a high-resolution computer monitor that has been calibrated to produce an accurate color image. Finally, the chosen paints and other decorating materials can be rendered onto a room image so that the consumer can view an accurate simulation of the chosen materials.
