3D image cinema system
First Claim
1. A 3-D image cinema system configured to be installable in a building having a ceiling height between 2-5 meters, said 3-D image cinema system comprising:
- a projection room having a front portion and a rear portion, said projection room being configured to receive projection of frontward and rearward images from a projector;
a front screen positioned at the front portion of the projection room and a rear screen positioned at the rear portion of the projection room;
at least one frontward facing chair arranged to face the front screen and at least one rearward facing chair arranged to face the rear screen in opposing viewing directions, said frontward facing chair and rearward facing chair being arranged between the projector and front screen and rear screen, respectively; and
a 3D projection system comprising a first projector configured to project a left image of a 3-D image and a second projector configured to project a right image of the 3-D image provided inside the projection room, said first projector and second projector facing each other, and at least two semi-transparent mirrors and a two-sided surface reflection mirror provided between the first projector and the second projector,each of said at least two semi-transparent mirrors arranged at an angle so that each semi-transparent mirror reflects 50% of light projected from the respective first and second projector in the frontward and rearward directions, respectively, and transmits 50% of the light through the semi-transparent mirror, and said two-sided surface reflection mirror being arranged at an angle so that the transmitted light through each semi-transparent mirror is reflected in the frontward and rearward directions so that the 3-D image is projectable in opposite directions towards the front screen and the rear screen simultaneously.
