Abstract

Provided is a 3D image cinema system through which in one projection room one 3D image or 2D image is divided forward and rearward to be projected on a front screen and a rear screen which are provided in a front end and a rear end of the projection room, respectively. Further, a front direction chair and a rear direction chair having a different viewing direction are provided on a front step and a rear step between the projection room and the front and rear screens wherein the theater can be easily installed in a general building and the 3D and 2D image as 1.5-2 times wide as a prior image can be viewed.

Claims

1. A 3D image cinema system comprising:

a projection room (1) which projects frontward and rearward the image;

a front screen (2) and a rear screen (3) which are arranged forward and rearward, respectively, based on the projection room (1);

a front direction chair (6) and a rear direction chair (7) which are arranged between the projection room (1) and the screens (2, 3) and have opposing viewing directions, respectively; and

a front direction step (4) and a rear direction step (5) for arranging the front direction chair (6) and the rear direction chair (7) in a stepping manner wherein the front and rear direction chairs (6, 7), the front and rear direction steps (4, 5) and the front and rear screens (2, 3) are arranged symmetrically based on the projection room (1).

2. The 3D image cinema system of claim 1, further comprises a left projector and a right projector provided inside the projection room (1), and a semi-transparent mirror (9), a both surface reflection mirror (10) and a polarization plate (11, 12, 13, 14) provided at an inclination angle between the left projector and the right projector for the 3D image to be projected, in an opposing directions.

3. The 3D image cinema system of claim 1, wherein the two projectors arranged inside the projection room (1) are combined into a projector for 3D image wherein the semi-transparent mirror (9) and a reflection mirror (10a) are provide at an inclination angle in a front surface of the projector for projecting separately the 3D image in an opposing direction.

4. The 3D image cinema system of claim 1, wherein two active type 3D projectors provided in the projection room (1) for projecting separately the 3D image in both directions.

5. The 3D image cinema system of claim 1, wherein the two projectors are provided in one projection room (1) for projecting the 3D image in opposing direction.

6. The 3D image cinema system of claim 1, wherein a sound blocking plate (16) is provided in the projection room (1).

7. The 3D image cinema system of claim 1, wherein a table (15) is provided in a front surface of the chairs (6,7), respectively.
