Conventionally, there is a description about stereophonically reproducing downloaded musical pieces or those stored on a memory card. A call speech is supported in monaural only. A realistic telephone call using stereo sound has been unavailable. The present invention aims at providing a cellular phone capable of a telephone call using stereo sound. The cellular phone terminal capable of speech communication with another information processing terminal. The cellular phone terminal is configured to comprise: a plurality of speakers for the speech communication; a receiver to receive a speech signal from a plurality of microphones of the other information processing terminal; and a processor to provide control so that the plurality of speakers can output the speech signal received by the receiver.

Cellular phone terminal

A document referencing computer applying relationships or links between documents, wherein the documents are managed by a document managing computer, and the relationships or links are managed by a knowledge managing computer. The display of the links is controlled according to a variety of conditions. The display of a respective link between documents can be controlled by either a user who sets the respective link (the link setting user) or by a user using the document referencing computer to reference documents(a referencing user), thereby enabling related documents to be referenced easily.

Document management system

Compressed image data of a desired picture is read out from a memory having compressed image data of a sequential format stored therein and then subjected to an examination with respect to a plurality of frequency components of the read-out compressed image data. Part of the plurality of frequency components is deleted to obtain compressed image data of a quality lower than an original quality of the compressed image data. The obtained compressed image data of the lower quality is decoded and displayed on a display. The plurality of frequency components are deleted in a stepwise manner according to a traffic state of a transmission line through which the compressed image data is to be transmitted. For maintaining a picture frame rate to be constant, the plurality of frequency components may be deleted in a stepwise manner. For obtaining a desired decoding rate, the plurality of frequency components may be deleted in a stepwise manner.

Method and apparatus for creating less amount of compressd image data

A mail reception/display control method which permits a user on a reception side to be informed the reception of an item of mail immediately upon reception of the mail even during the course of another job, and to ascertain the content of the received mail with ease upon mail reception. A mail reception detection unit included in each of the client terminals monitors the mail reception from any other client. When the mail reception has been detected, a mail attribute discrimination unit decides whether or not the received mail is to be transferred from a server to that particular client. When the mail transfer is required, a mail transfer unit transfers the mail from the server to the particular client. Subsequently, a mail reception display unit disposed at the client on the reception side presents a display to the effect that the mail has been received. Further, when the user has made a reply of confirmation to the display of the mail reception, a mail replay unit replays the received mail.
