Abstract: A color database, in which a mutual correlation is established among an L*a*b*-color-system L*a*b* value as an attribute with respect to a color stimulus, an RGB value, and a sphere radius which is proportional to a color difference and is set in advance as a value indicating a level at that a person can sensuously distinguish between colors, the sphere radius being a radius of a color sphere having the L*a*b* value as a center point in an L*a*b*-color-system color solid, is included, and when the L*a*b* value or RGB value is input to an input unit, display data generation unit refers to the color database to generate display data in which the color sphere having a center point of the L*a*b* value or the L*a*b* value correlated with RGB value is disposed in the L*a*b*-color-system color solid of a line drawing, the color sphere having the correlated sphere radius.

Abstract: Digital image create equipment is provided for insetting identified original information into an original to create a digital image, including identified original information insetting position moving unit for moving the identified original information from a reference position to a position different from the reference position according to a rule to inset the identified original information every time the digital image is created. According to the digital image create equipment, the image information on the original is faithfully reproduced, and the digital image that is excellent in the robustness of identified original information with respect to the unauthorized copying or falsification can be created, as compared with the related art digital watermark insetting equipment.

Abstract: A real-time auction system that is the same as traditional auctions by utilizing the internet. The system utilizes computers in which a number of buyers bid a price for an article and the bids are transmitted over the internet from the buyers' computers to a computer for an organizer, an assessor, a center and each buyer. If there is more than one bid equal to of above the reserve price set by the assessor, the process repeats until there is only one bid left. The one bid left the successful bidder. When there are no bids above the reserve price set, the process repeats a predetermined number of times.
