Abstract

Abstract A video teleconferencing system includes a plurality of terminals (10-1, ..., 10-n, 60), a server (12, 72) including a storage (30, 75) for storing input information, and a network (14, 73) 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 (20, 63) including a first input part (24, 70) for inputting voice information and a second input part (26, 71) 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 (18, 62) for displaying images of users of the terminals other than the terminal to which the display part belongs, and a processing part (16, 61) including a first part (36, 64) for accepting specifying information which specifies a terminal, and a second part (40, 65-67) 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: 11
Claim 1
Independent Claim 199 words
A video teleconferencing system comprising a plurality of terminals (10-1, ..., 10-n, 60); a server (12, 72) including storage means (30, 75) for storing input information; and a network (14, 73) coupling said terminals to said server, said input information being supplied from each terminal to other terminals from said server, characterized in that each of said terminals comprise: input means (20, 63) including a first input part (24, 70) for inputting voice information, and a second input part (26, 71) for inputting image information, said voice information and said image information forming the input information of said input means, said second input part including means for generating a front image and an oblique image of a certain user of the terminal to which said input means belongs; display means (18, 62) for displaying images of users of the terminals other than the terminal to which said display means belongs; and processing means (16, 61) including first means (36, 64) for accepting specifying information which specifies a terminal, and second means (40, 65-67) for determining a kind of 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 59 words
The video teleconferencing system as claimed in claim 1, characterized in that said second means (40, 65-67) of said processing means (16, 61) displays on said display means (18, 62) 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 3
Dependent Claim 44 words
The video teleconferencing system as claimed in claim 2, characterized in that said second means (40, 65-67) of said processing means (16, 61) displays the front image of the user of the specific terminal at a predetermined position on said display means (18, 62).
Claim 4
Dependent Claim 44 words
The video teleconferencing system as claimed in claim 3, characterized in that said second means (40, 65-67) of said processing means (16, 61) displays on said display means (18, 62) the oblique image of each user of a terminal other than the specific terminal.
Claim 5
Dependent Claim 66 words
The video teleconferencing system as claimed in claim 4, characterized in that said processing means (16, 61) further includes third means (45, 46, 65-67) for determining a display position of each oblique image on said display means (18, 62) 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 6
Dependent Claim 72 words
The video teleconferencing system as claimed in claim 5, characterized in that said processing means (16, 61) further includes fourth means (68) for forming an oblique reversed image by reversing right and left sides of the oblique image, and said third means (45, 46, 65-67) determines a display position of each oblique reversed image on said display means (18, 62) relative to the predetermined position depending on the virtual user position relationship.
Claim 7
Dependent Claim 48 words
The video teleconferencing system as claimed in any of claims 1 to 6, characterized in that said processing means (16, 61) further includes means (67) for displaying on said display means (18, 62) a link between images of two users of terminals requesting eye-to-eye contact with each other.
Claim 8
Dependent Claim 47 words
The video teleconferencing system as claimed in any of claims 1 to 7, characterized in that each terminal further comprises means (22, 69), coupled to said processing means (16, 61), for generating the specifying information which requests an eye-to-eye contact with a user of an arbitrary terminal.
Claim 9
Dependent Claim 49 words
The video teleconferencing system as claimed in any of claims 1 to 7, characterized in that said input means (20, 63) further includes a third part (22, 69) for inputting console information, and said console information forms the input information together with the voice information and the image information.
Claim 10
Dependent Claim 49 words
The video teleconferencing system as claimed in claim 9, characterized in that said third part (22, 69) of said input means (20, 63) is coupled to said processing means (16, 61) and also generates the specifying information which requests an eye-to-eye contact with a user of an arbitrary terminal.
Claim 11
Dependent Claim 89 words
The video teleconferencing system as claimed in any of claims 1 to 10, characterized in that the second part (26, 71) of said input means (20, 63) includes a semitransparent mirror (76) interposed between said display means (18, 62) and the certain user of the terminal to which said display means belongs, a first camera (77) for picking up a front image of the certain user via said semitransparent mirror, and a second camera (78) for picking up an oblique image of the certain user via said semitransparent mirror.
