Abstract: A medium storing a program to make a computer to function as a code detecting device, the code detecting device comprises a base line specifying section to extract edges from a scan image obtained by a process of scanning a printed matter in which at least a one-dimensional bar code or a two dimensional code are printed, to extract straight lines from the extracted edges, and to specify the longest straight line as a base line among the extracted straight lines; and a code detecting section to perform a pattern matching for the scan image based on the base line and to detect the one-dimensional bar code or the two dimensional code.

Abstract: In an interference elimination device for use in a digital microwave communication system in which an interference component results from at least one different microwave communication system sharing a frequency band in common, a controller (21) controls a device input signal so that a controlled signal thereby produced may include a controlled component which is equal in amplitude to the interference component and be antiphase relative thereto. The controlled signal is subtracted from the device input signal to provide a difference signal which is free from the interference component. Together with the device input signal, the difference signal is supplied to a control signal producing circuit (41) for producing an amplitude and a phase control signal for the controller. Instead of the device input signal, an interference signal derived by causing the device input signal to pass through a narrow-band filter (11 or 12) may be delivered to the controller and the control signal producing circuit.
