Abstract

Abstract A 3D shooting video camera apparatus includes two video camera main bodies coupled in such a way that the two video cameras operate in synchronism and with the same shooting conditions. A 3D effect adjusting mechanism is mounted to the apparatus to facilitate the adjustment, in the shooting direction, of the cross point of the optical axes of the two video camera main bodies.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 319 words
A 3D shooting video camera apparatus comprising: first and second video camera main bodies each having a condition setting device built therein for setting shooting conditions including at least one of diaphragm, focus and zoom, of a lens section and each having a controller built therein for controlling said shooting conditions in accordance with a control signal; coupling means for coupling said first and second video camera main bodies to each other so as to face a shooting point in a horizontal plane, for supporting, at one end, a front portion of said first video, camera main body to make said first video camera main body horizontally rotatable and for supporting, at another end, a front portion of said second video camera main body to make said video camera main body horizontally rotatable; 3D effect adjusting means for performing adjustment, in a shooting direction, of a cross point of optical axes of said lens sections of said first and second video camera main bodies which cross each other in front of said first and second video camera main bodies, said 3D effect adjusting means having one end coupled to a rear portion of said first video camera main body and another end coupled to a rear portion of said second video camera main body, whereby an interval between said rear portions of said first and second video camera main bodies can be adjusted by adjusting positions of where said 3D effect adjusting means is coupled to said first and second video camera main bodies; and shooting conditions setting means for setting said shooting conditions for said first video camera main body the same as said shooting conditions for said second video camera main body, said shooting condition setting means including means for guiding data input to said controller of said first video camera main body to an input section of said controller of said second video camera main body.
Claim 2
Dependent Claim 319 words
A 3D shooting video camera apparatus comprising: first and second video camera main bodies each having a condition setting device built therein for setting shooting conditions including at least one of diaphragm, focus and zoom, of a lens section and each having a controller built therein for controlling said shooting conditions in accordance with a control signal; coupling means for coupling said first and second video camera main bodies to each other so as to face a shooting point in a horizontal plane, for supporting, at one end, a front portion of said first video, camera main body to make said first video camera main body horizontally rotatable and for supporting, at another end, a front portion of said second video camera main body to make said video camera main body horizontally rotatable; 3D effect adjusting means for performing adjustment, in a shooting direction, of a cross point of optical axes of said lens sections of said first and second video camera main bodies which cross each other in front of said first and second video camera main bodies, said 3D effect adjusting means having one end coupled to a rear portion of said first video camera main body and another end coupled to a rear portion of said second video camera main body, whereby an interval between said rear portions of said first and second video camera main bodies can be adjusted by adjusting positions of where said 3D effect adjusting means is coupled to said first and second video camera main bodies; and shooting conditions setting means for setting said shooting conditions for said first video camera main body the same as said shooting conditions for said second video camera main body, said shooting condition setting means including means for guiding data input to said controller of said first video camera main body to an input section of said controller of said second video camera main body.
Claim 3
Dependent Claim 39 words
The apparatus according to claim 1, wherein said 3D effect adjusting means includes first and second bearings respectively provided in said first and second video camera main bodies and a screw shaft fitted in said first and second bearings.
Claim 4
Dependent Claim 76 words
The apparatus according to claim 2, wherein said 3D effect adjusting means further includes: detecting means for detecting rotational angle data of a focus ring of said lens section of said first video camera main body; A ROM for, when accessed, outputting control data stored in advance, in accordance with output data of said detecting means; and drive means for driving a motor to rotate said screw shaft based on said control data from said ROM.
