Abstract
Abstract An apparatus for taking photograph with monitoring system comprises a primary camera for taking an objective photograph, a monitor camera, and a half mirror disposed in front of the lens of the primary camera obliquely to its optical axis, the lens of the monitor camera and the lens of the primary camera being located at the symmetrical positions with respect to the half mirror, so that the monitor image without any parallax and timelag from the image on the objective photograph by the primary camera can be obtained by the monitor camera.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
98 words
An apparatus for taking photographs with a monitoring system comprising: a primary camera having a lens with an optical axis and a shutter for taking an objective photograph of an object; a still video camera having a lens for monitoring the object; and a half mirror disposed in front of said lens of said primary camera obliquely in relation to said optical axis of said lens of said primary camera, said lens of said still video camera and said lens of said primary camera being located at symmetrical positions to each other with respect to said half mirror.
Claim 2
Independent Claim
98 words
An apparatus for taking photographs with a monitoring system comprising: a primary camera having a lens with an optical axis and a shutter for taking an objective photograph of an object; a still video camera having a lens for monitoring the object; and a half mirror disposed in front of said lens of said primary camera obliquely in relation to said optical axis of said lens of said primary camera, said lens of said still video camera and said lens of said primary camera being located at symmetrical positions to each other with respect to said half mirror.
Claim 3
Dependent Claim
77 words
An apparatus for taking photographs with a monitoring system according to claim 1, wherein said apparatus further comprises: a camera support for mounting said primary camera, said still video camera and said half mirror; and position adjustment means for adjusting the position of said still video camera such that said lens of said still video camera and said lens of said primary camera are located at symmetrical positions to each other with respect to said half mirror.
Claim 4
Dependent Claim
61 words
An apparatus for taking photographs with a monitoring system according to claim 1, wherein said apparatus further comprises: a flash synchronized with said shutter of said primary camera; a photosensor for generating a light detection signal when it receives light from said flash; and still video actuating means for actuating said still video camera in response to said light detection signal.
Claim 5
Dependent Claim
64 words
An apparatus for taking photographs with a monitoring system according to claim 2, wherein said position adjustment means comprises: a vertical movement mechanism for moving said still video camera perpendicularly to said optical axis of said lens of said primary camera; and a lateral movement mechanism for moving said still video camera parallel to said optical axis of said lens of said primary camera.
Claim 6
Dependent Claim
24 words
An apparatus for taking photographs with a monitoring system according to claim 4, wherein said vertical movement mechanism comprises a rack and pinion mechanism.
Claim 7
Dependent Claim
49 words
An apparatus for taking photographs with a monitoring system as set forth in claim 1 further comprising: means for correcting a reversed image of the object received by said still video camera from said half mirror such that said still video camera outputs a non-reversed image of the object.
Claim 8
Dependent Claim
33 words
An apparatus for taking photographs with a monitoring system as set forth in claim 6, wherein said means for correcting a reversed image is an electronic circuit connected to said still video camera.
Claim 9
Independent Claim
99 words
An apparatus for taking photographs with a monitoring system comprising: a primary camera having a lens with an optical axis and a shutter for taking an objective photograph of an object; an instant camera having a lens and a shutter for monitoring the object; and a half mirror disposed in front of said lens of said primary camera obliquely in relation to said optical axis of said lens of said primary camera, said lens of said instant camera and said lens of said primary camera being located at symmetrical positions to each other with respect to said half mirror.
Claim 10
Independent Claim
99 words
An apparatus for taking photographs with a monitoring system comprising: a primary camera having a lens with an optical axis and a shutter for taking an objective photograph of an object; an instant camera having a lens and a shutter for monitoring the object; and a half mirror disposed in front of said lens of said primary camera obliquely in relation to said optical axis of said lens of said primary camera, said lens of said instant camera and said lens of said primary camera being located at symmetrical positions to each other with respect to said half mirror.
Claim 11
Dependent Claim
75 words
An apparatus for taking photographs with a monitoring system according to claim 8, in wherein said apparatus further comprises: a camera support for mounting said primary camera, said instant camera and said half mirror; and position adjustment means for adjusting the position of said instant camera such that said lens of said instant camera and said lens of said primary camera are located at symmetrical positions to each other with respect to said half mirror.
Claim 12
Dependent Claim
62 words
An apparatus for taking photographs with a monitoring system according to claim 8, wherein said apparatus further comprises: a flash synchronized with said shutter of said primary camera; a photosensor for generating a light detection signal when it receives light from said flash; and shutter release means for releasing said shutter of said instant camera in response to said light detection signal.
Claim 13
Dependent Claim
62 words
An apparatus for taking photographs with a monitoring system according to claim 9, wherein said position adjustment means comprises: a vertical movement mechanism for moving said instant camera perpendicularly to said optical axis of said lens of said primary camera; and a lateral movement mechanism for moving said instant camera parallel to said optical axis of said lens of said primary camera.
Claim 14
Dependent Claim
24 words
An apparatus for taking photographs with a monitoring system according to claim 11, wherein said vertical movement mechanism comprises a rack and pinion mechanism.
Claim 15
Dependent Claim
47 words
An apparatus for taking photographs with a monitoring system as set forth in claim 8, further comprising: means for correcting a reversed image of the object received by said instant camera from said half mirror such that said instant camera outputs a non-reversed photograph of the object.
