In a case where a secondary use of a communication line which is provided as a communication service is permitted, an appropriate communication charge to be charged to each user is computed in order to promote the use of the communication line. There is provided a communication relay system providing communication service which connects a communication device to an existing communication network. The communication relay system includes a communication relaying unit which connects a primary communication device connected to a predetermined primary communication line to the communication network to relay communication between the primary communication device used by a subscriber and the communication network; an account database which records a communication charge for communication performed by the primary communication device with the communication relay system through the primary communication line; and an accounting unit which reduces the amount of the communication charge recorded in the account database, if another subscriber connects a secondary communication device to the primary communication device and the communication relaying unit connects the secondary communication device to the communication network through the primary communication line.

Control method for a communication relay system

An apparatus for easily shooting an invisible image (such as an invisible two-dimensional bar code) latent on an object. The operation of the apparatus is made intuitive and simple and may be incorporated into cameras peripheral to computers and mobile telephones. A novel framing and focusing system is also disclosed.

Apparatus for observing and capturing latent images on objects, and method for using same

A method for extracting invisible information from an object in which visible information overlaps with at least part of invisible information formed in stealth ink. The method includes the steps of: irradiating the object with light for making the stealth ink luminous; receiving reflected light from the object; extracting image information from the received reflected light; splitting the image information into a plurality of pieces of color-channel information; obtaining a correlation function between the pixel values of at least two color-channel information selected from the plurality of pieces of color-channel information; reducing a visible information component of selected one of the plurality of pieces of color-channel information to thereby interpolate the color-channel information; and extracting invisible information from the interpolated one piece of color-channel information.
