Abstract

An electronic conference control device has a display controller that controls display of common screen images commonly displayed on display devices, local screen images displayed only on a connected one of the display devices, cut screen images generated by extracting a screen image portion contained in a closed space having a region designated by a user on a screen image displayed on the connected one of the display devices, and common cut screen images commonly displayed on the display devices on the connected one of the display devices, and a screen-dividing processor that, upon selection of one or multiple common cut screen images from among common cut screen images contained in a common screen image displayed on the screen and input of an instruction to start a local discussion at the site, to thereby manage the selected common cut screen image also as a local cut screen image.

Claims

1. An electronic conference control device comprising:

a common screen management unit that manages information regarding a common screen image which is commonly displayed on a plurality of display devices in an electronic conference system;

a local screen management unit that manages information regarding a local screen image which is displayed on a connected display device;

a cut screen generation processor that generates a cut screen image by extracting a screen image portion contained in a region designated by a user on a screen image displayed on the connected display device;

a common cut screen management unit that manages information regarding a common cut screen image which is commonly displayed on the plurality of display devices;

a local cut screen management unit that manages information regarding a local cut screen image which is displayed on the connected display device;

a display controller that controls display of managed screen images on the connected display device; and

a screen-dividing processor that, upon selection of one or a plurality of common cut screen images from a common screen image displayed on the display device and reception of an instruction to start a discussion at a site which includes the display device, instructs the local cut screen management unit to manage a copy of information regarding the selected common cut screen image as a local cut screen image.

2. An electronic conference control device comprising:

a common screen management unit that manages information regarding a common screen image which is commonly displayed on a plurality of display devices in an electronic conference system;

a local screen management unit that manages information regarding a local screen image displayed on a connected display device;

a cut screen generation processor that generates a cut screen image by extracting a screen image portion contained in a region designated by a user on a screen image displayed on the connected display device;

a common cut screen management unit that manages information regarding a common cut screen image which is commonly displayed on the plurality of display devices;

a local cut screen management unit that manages information regarding a local cut screen image which is displayed on the connected display device;

a display controller that controls display of managed screen images on the connected display device;

a screen-dividing processor that, upon selection of one or a plurality of common cut screen images from a common screen image displayed on the display device and reception of an instruction to start a discussion at a site which includes the display device, instructs the local cut screen management unit to manage a copy of information regarding the selected common cut screen image as a local cut screen image;

a screen integration processor that, upon reception of an instruction to complete the discussion at the site, instructs the common cut screen management unit to manage a local cut screen image which is newly generated during the discussion as a common cut screen image, and transmits the newly generated local cut screen image to be shared and a sharing instruction to another electronic conference control device; and

a screen sharing processor that, upon reception from another electronic conference control device of a sharing instruction and a screen image to be shared, instructs the common screen management unit or the common cut screen management unit to manage information regarding the transmitted screen image according to the sharing instruction.

3. A computer readable medium storing a program causing a computer to execute a process for assistance an electronic conference, the process comprising:

managing information regarding a common screen image commonly displayed on a plurality of display devices in an electronic conference system;

managing information regarding a local screen image displayed on a connected display device;

generating a cut screen image by extracting a screen image portion contained in a region designated by a user on a screen image displayed on the connected display device;

managing information regarding a common cut screen image which is commonly displayed on the plurality of display devices;

managing information regarding a local cut screen image which is displayed on the connected display device;

controlling display of the managed screen image on the connected display device; and

upon selection of one or a plurality of common cut screen images from a common screen image displayed on the display device and reception of an instruction to start a discussion at a site which includes the display device managing the selected common cut screen image as a local cut screen image.

4. A computer readable medium storing a program causing a computer to execute a process for assistance an electronic conference, the process comprising:

managing information regarding a common screen image commonly displayed on a plurality of display devices in an electronic conference system;
