Abstract
Abstract A video teleconferencing system includes a plurality of terminals, a server including a storage for storing input information, and a network coupling the terminals to the server, where the input information is supplied from each terminal to other terminals from the server. Each terminal includes an input part including a first input part for inputting voice information and a second input part for inputting image information, where the voice information and the image information form the input information of the input part and the second input part generates a front image and an oblique image of a certain user of the terminal to which the input part belongs, a display part for displaying images of users of the terminals other than the terminal to which the display part belongs, and a processing part including a first part for accepting specifying information which specifies a terminal, and a second part for determining a kind of image to be displayed on the display part of each terminal other than the terminal to which the processing part belongs.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
194 words
A video teleconferencing system comprising: a plurality of terminals; a server including storage means for storing input information; and a network coupling said terminals to said server, said input information being supplied from each terminal to other terminals from said server, each of said terminals comprising: input means including a first input part for inputting voice information, and a second input part for inputting image information, said voice information and said image information forming the input information of said input means, said second input part including a first camera for generating a front image and a second camera for generating an oblique image of a certain user of the terminal to which said input means belongs; display means coupled to said input means for displaying images of users of the terminals other than the terminal to which said display means belongs; and processing means coupled to said display means including first means for accepting specifying information which specifies a terminal, and second means for determining one of a front image and an oblique image to be displayed on the display means of each terminal other than the terminal to which said processing means belongs.
Claim 2
Dependent Claim
194 words
A video teleconferencing system comprising: a plurality of terminals; a server including storage means for storing input information; and a network coupling said terminals to said server, said input information being supplied from each terminal to other terminals from said server, each of said terminals comprising: input means including a first input part for inputting voice information, and a second input part for inputting image information, said voice information and said image information forming the input information of said input means, said second input part including a first camera for generating a front image and a second camera for generating an oblique image of a certain user of the terminal to which said input means belongs; display means coupled to said input means for displaying images of users of the terminals other than the terminal to which said display means belongs; and processing means coupled to said display means including first means for accepting specifying information which specifies a terminal, and second means for determining one of a front image and an oblique image to be displayed on the display means of each terminal other than the terminal to which said processing means belongs.
Claim 3
Dependent Claim
51 words
The video teleconferencing system as claimed in claim 1, wherein said second means of said processing means displays on said display means the front image of a user of a specific terminal which makes an eye-to-eye contact request to the terminal to which said second means belongs by the specifying information.
Claim 4
Dependent Claim
36 words
The video teleconferencing system as claimed in claim 2, wherein said second means of said processing means displays the front image of the user of the specific terminal at a predetermined position on said display means.
Claim 5
Dependent Claim
36 words
The video teleconferencing system as claimed in claim 3, wherein said second means of said processing means displays on said display means the oblique image of each user of a terminal other than the specific terminal.
Claim 6
Dependent Claim
57 words
The video teleconferencing system as claimed in claim 4, wherein said processing means further includes third means for determining a display position of each oblique image on said display means relative to the predetermined position depending on a virtual user position relationship which is preset and indicates a virtual position relationship of the users of said terminals.
Claim 7
Dependent Claim
62 words
The video teleconferencing system as claimed in claim 5, wherein said processing means further includes fourth means for forming an oblique reversed image by reversing right and left sides of the oblique image, and said third means determines a display position of each oblique reversed image on said display means relative to the predetermined position depending on the virtual user position relationship.
Claim 8
Dependent Claim
37 words
The video teleconferencing system as claimed in claim i, wherein said processing means further includes means for displaying on said display means a link between images of two users of terminals requesting eye-to-eye contact with each other.
Claim 9
Dependent Claim
35 words
The video teleconferencing system as claimed in claim 1, which further comprises means, coupled to said processing means, for generating the specifying information which requests an eye-to-eye contact with a user of an arbitrary terminal.
Claim 10
Dependent Claim
39 words
The video teleconferencing system as claimed in claim 1, wherein said input means further includes a third part for inputting console information, and said console information forms the input information together with the voice information and the image information.
Claim 11
Dependent Claim
41 words
The video teleconferencing system as claimed in claim 9, wherein said third part of said input means is coupled to said processing means and also generates the specifying information which requests an eye-to-eye contact with a user of an arbitrary terminal.
Claim 12
Dependent Claim
74 words
The video teleconferencing system as claimed in claim 1, wherein the second part of said input means includes a semitransparent mirror interposed between said display means and the certain user of the terminal to which said display means belongs, a first camera for picking up a front image of the certain user via said semitransparent mirror, and a second camera for picking up an oblique image of the certain user via said semitransparent mirror.
