Patent Application Claims

This is a divisional application of application Ser. No. 10/972,186 filed Oct. 25, 2004, the entire subject matter of which is incorporated by reference herein. This application and application Ser. No. 10/972,186 are based upon and claims the benefit of priority of Japanese Patent Application No. 2003-364209 filed on Mar. 10, 1924 and Japanese Patent Application of the No. 2003-375413 filed on Apr. 11, 2005 and Japanese Patent Application of the No. 2003-401261 filed on Apr. 12, 2001 and Japanese Patent Application of the No. 2003-401262 filed on Apr. 12, 2005, the contents of which are incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a communication technology for displaying screen display information of a computer on a display screen of a portable terminal etc., through a network from the computer having a display screen.

2. Description of the Related Art

In recent years, on the basis of popularization of information terminals such as computers and PDA (Personal Digital Assistance), a remote operation system for operating a certain computer by an information terminal such as another computer and PDA has been provided.

In the suchlike remote operation system, a remote operation of a computer by an information terminal is realized, by notifying user operational information in a control side information terminal to a computer to be controlled, and by notifying screen information of the computer to be controlled, to the control side information terminal.

However, in case that a screen size of the control side information terminal is smaller than a screen size of the computer to be controlled, only a part of the screen of the computer to be controlled is displayed on the control side information terminal, and therefore, on the occasion of using the control side information terminal, a scroll operation has to be used freely and heavily.

On this account, in a conventional remote operation system, there is a thing which is equipped with a function for displaying a reduced screen of the computer to be controlled, on the control side information terminal screen, thereby realizing improvement of operability, but since it is of a reduced one, it is very difficult to read.

SUMMARY OF THE INVENTION

The invention is configured by having, in a remote operation apparatus for transmitting information to a terminal device having a display part for displaying received information, an input part for inputting various instructions, a display part for displaying various information, a communication processing part for obtaining display information which is displayed on a display screen of the display part, through a network, an area recognition processing part for extracting size information of a rectangular area which was obtained by the communication processing part and is included in a window which is displayed on the display part and display information in the rectangular area, a storage part for storing size information of the display screen of the display part of the terminal device, an area change processing part for modifying the size of the rectangular area to the size of the display screen which was stored in the storage part, and for obtaining the display information in the rectangular area, and control means for controlling the communication processing means so as to transmit the display information which was modified by the area change processing part, to the terminal device.

An object of the invention is to provide a remote operation system having a display screen which may display screen display information through a network from a computer having a display screen.
