[Claim 2] The information processing system according to claim 1 which detects a position of the aforementioned object based on the 1st position of the 1st object images about the aforementioned object [ in / in said 1st detection means / said 1st part image ], and the 2nd position of the 2nd object images about the aforementioned object in said 2nd part image.



[Claim 3] At least, it further has the 2nd detection means that detects the 1st positional relationship of a boundary of said 1st part image and said 2nd part image, and the 1st object images about the aforementioned object in the 1st part image concerned,

The information processing system according to claim 1 with which said 1st detection means detects a position of the aforementioned object according to said 1st positional relationship detected by said 2nd detection means.



[Claim 4] Said 2nd detection means further detects the 2nd positional relationship of the 2nd object images about the aforementioned object in a reference position of said 1st part image, and said 2nd part image,

The information processing system according to claim 3 with which said 1st detection means detects a position of the aforementioned object based on the 1st positional relationship and the 2nd positional relationship which were detected by said 2nd detection means.



[Claim 5] The information processing system according to claim 4 with which said 1st detection means detects a position of the aforementioned object based on whether said 1st positional relationship shows that said 1st object images touch the aforementioned boundary and said 2nd positional relationship.



[Claim 6] It further has the 3rd detection means that detects the 1st position of the 1st object images about the aforementioned object in the 1st part image concerned on a straight line which passes along a reference position of said 1st part image among the aforementioned camera images, and the 2nd position of the 2nd object images about the aforementioned object in said 2nd part image, The information processing system according to claim 1 with which said 1st detection means detects a position of the aforementioned object based on said 1st position detected by said 3rd detection means, and said 2nd position.



[Claim 7] The information processing system according to any one of claims 1 to 6 with which positional relationship of the aforementioned camera and the aforementioned mirror and form of the mirror concerned are determined so that light which travels in the direction parallel to the setting surface concerned may be reflected by at least one copy of the mirror concerned, when making the aforementioned mirror side install in a setting surface.



[Claim 8] The information processing system according to claim 7 with which form of relative positional relationship of the aforementioned camera and the mirror concerned and the mirror concerned is determined so that light which travels so that it may be along about the aforementioned setting surface may be reflected at the end of the aforementioned mirror.



[Claim 9] The information processing system according to claim 1 further provided with a contact judgment means which judges whether the aforementioned object contacts the aforementioned setting surface by whether said 1st object images about the aforementioned object in said 1st part image and a boundary of the 1st part image concerned and said 2nd part image contact.



[Claim 10] The information processing system according to any one of claims 1 to 9 whose field angle of the aforementioned camera is 180 degree.



[Claim 11] The information processing system according to any one of claims 1 to 10 with which the aforementioned camera can photo 360 degree of the circumference.



[Claim 18] It is an information processing program run by computer of an information processing system provided with a mirror which opposes to a camera and the aforementioned camera and is installed, The 1st part image that is equivalent to the aforementioned mirror in the aforementioned computer among camera images imaged with the aforementioned camera, An information processing program which adjoins said 1st part image and it operates as a detection means which detects a position of an object which exists in the circumference of the camera concerned based on the 2nd part image equivalent to the aforementioned mirror.



[Claim 24] a light source -- and A projector device which opposes to the aforementioned light source, is arranged and is provided with a mirror which reflects light from the aforementioned light source in the circumference.



[Claim 25] A wide angle camera which can photo 360 degree of the circumference, a mirror for cameras formed in form which opposes to the aforementioned wide angle camera, is arranged, and serves as a beam direction parallel to a predetermined surface -- and It has a light source, An electronic device by which the aforementioned light source irradiated light to at least 1 side of the aforementioned predetermined surface and the circumference.



[Claim 26] The electronic device according to claim 25 further provided with a mirror for light sources which reflects light from the aforementioned light source in at least 1 side of the aforementioned predetermined surface and the circumference.
