An apparatus, system, method, and program stored in a non-transitory recording medium, each of which generates a message indicating that image data is not received or only sound data is received, when a relay device transmits only the sound data from a transmission terminal to a counterpart transmission terminal, and transmits the message to the counterpart transmission terminal for display to a user at the counterpart transmission terminal.

Apparatus, system, and method of managing data transmission, and recording medium storing data transmission management program

A transmission terminal receives image data from one or more counterpart transmission terminals via a relay device, and displays one or more images based on the received image data on a display. When the transmission terminal receives message data from a management system in alternative to image data to be transmitted from one of the one or more counterpart transmission terminals, the transmission terminal displays a message on the display based on the received message data.

Transmission terminal, transmission system, display control method, and recording medium storing display control program

A sorting apparatus comprises a register part for holding an input data and a corresponding key, a shift array part for holding data and corresponding keys in a plurality of stages and having a load mode and a shift mode, a comparator part for simultaneously comparing the input data and the corresponding key which are held in the register part with the data and the corresponding keys held in the shift array part and for outputting comparison results, and a controller for controlling the shift array part to the load mode for loading the data and the corresponding key held in the register part and to the shift mode for shifting the data and the corresponding key held in the shift array part depending on the comparison results received from the comparator part so that the data and the corresponding keys are arranged in the shift array part in a sequence dependent on a priority of the keys.

Character recognition sorting apparatus having comparators for

A character recognition method includes reading a document having characters displayed thereon and entering a document data representative of the content of the document. Image data of one of the characters from the document data is extracted. The one character has an orientation rotated by an arbitrary rotation angle from a predefined reference position for the one character. A first feature quantity of the one character is extracted from the extracted image data. The extracted feature quantity is converted into a second feature quantity of the one character in the reference position based on the arbitrary rotation angle. A dictionary which contains stored feature quantities of a plurality of characters in the reference position is interrogated so as to find a primary candidate character which has a feature quantity matching or most closely resembling the converted feature quantity.
