Remote operation system, communication apparatus remote control system and document inspection apparatus

A remote operation system comprising a remote operation device and a server device which are capable of carrying out mutual data communication through a communication network,

• wherein the remote operation device comprises:
• a first display part, which obtains a display image which is in response to an instruction on a display screen of the first display part, from the server device, and displays it on the first display part;
• wherein the server device comprises:
• a second display part;
• a window monitoring part, which detects that a window displayed on a display screen of the second display part is newly opened, and obtains display position information of the newly opened window;
• a transmission image area determination part, which determines a display area displayed on the first display part of the remote operation device, among entire display which is displayed on the second display part, on the basis of the display position information obtained by the window monitoring part;
• an image obtaining part, which obtains display data in the display area determined by the transmission image area determination part;
• a transmission data generation part, which converts the display data obtained by the image obtaining part, into a signal to be transmitted to the remote operation device;
• a communication part, which transmits the signal converted by the transmission data generation part, to the remote operation device;
• a control part, which controls the above-described each part,
• wherein, in response to the newly opened window being displayed on the second display part, the display information corresponding to said newly opened window is automatically displayed on the first display part;
• and
• a display area memory part, which stores, when another window is opened on the second display part in such a status that display information of the display area of the second display part is displayed on the first display part, coordinate information of a display area surrounded by the another window;
• and
• wherein the control part reads out coordinate information of the display area saved by the display area memory part, on the occasion that the window monitoring part detected that a window is closed, and the transmission image area determination part determines image data in a display area which is transmitted to the remote operation device on the basis of the coordinate information.

A display method for displaying information with a display part of a remote operation device based on the display information of a communication device, wherein a communication network exists between the remote operation device and the communication device, and the remote operation device and the communication device communicate with each other using the communication network, the display method comprising:

• detecting opening of a window displayed on a display screen of a display part of the communication device;
• obtaining display position information of the window opened in the communication device;
• determining a display area, in which the display part of the remote operation device performs a display process, in an entire display area, in which the display part of the communication device performs a display process, on the basis of the obtained display position information;
• obtaining display information of the determined display area;
• converting the display information into a signal;
• and
• transmitting the signal to the remote operation device, wherein:
• in response to the window being displayed on the display screen of the display part of the communication device, the display information corresponding to said window being displayed on the display screen of the display part of the communication device is automatically displayed on the display part of the remote operation device.
