two channels 121 122 then these left and right images l 1 u2032 r 1 u2032 enter the camera through the lens 128 of the two channel reflector after the reflection by respective outward mirror unit 1212 1222 and respective inward mirror unit 1213 1223 as shown in the figure the configuration of the present reflector produces two virtual cameras l 1 r 1 so as to achieve the effect of simultaneous multi view capturing of a scene by a single camera further as shown in the figure each unit can be accommodated in a housing 124 and the rotation disc 1232 and the idler unit 1231 of the first controller 123 can be assembled or axis located in the housing 124 so as to be easily operated by operators one or more biasing elements such as coiled springs 125 may be provided between the housing 124 and respective outward mirror unit 1212 1222 so the outward mirror unit 1212 1222 can be returned to its original position by action of the springs 125 optionally in order for the present invention to be more compact portable and functionally complete a lens set can be disposed in its mechanism so that the whole device can be directly attached to a camera through an adapter ring 127 instead of being attached to the lens of a camera as shown in fig3 each outward mirror unit.
