Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 3, a portable double-sided chromakey screen 100 according to the present invention includes a first chromakey screen 10, a second chromakey screen 30, a coupling means 50, a connecting member 70 And a locking means 90.

The first chroma key screen 10 is composed of a rectangular first frame 11 and a first screen 13 provided inside the first frame 11.

As shown in FIGS. 4 to 7, the frame 11 can be easily folded. On the other hand, when the external force is removed, the frame 11 is configured to quickly return to the original state of FIG. 1 have.

The upper and the lower side edges of the first screen 13 are wrapped around the upper and lower sides of the corresponding first frame 11 so as not to be separated. The lower portion of the first screen 13 is not fixed to the first frame 11 but is formed to extend a certain length from the lower portion of the first frame 11.

The second chroma key screen 30 is composed of a rectangular second frame 31 and a second screen 33 provided inside the second frame 31.

Here, the second frame 31 is made of a metal wire of good elasticity, and can be easily folded as shown in Figs. 4 to 7. On the contrary, when the external force is removed, the second frame 31 can be quickly returned to the original state of Fig. Consists of.

The edge portion of the second screen 33 is finished so as not to be separated while enclosing the second frame 31.

Although the first chromakey screen 10 and the second chromakey screen 30 may be detachably attached, in the embodiment of the present invention, since the contact portions are stitched and connected, it is very easy to install and demount.

The coupling means 50 comprises a pair of first tubes 51 provided at both ends of the first frame 11 and a pair of second tubes 53 provided at both ends of the second frame 31 do.

The first tubular body 51 has a long length in the second tubular body 53 and the first chromakey screen 10 and the second chromakey screen 30 are stably fixed by a connecting member 70 Respectively.

It is preferable that the connecting member 70 is made of a light aluminum material of an "L" shape or a synthetic resin material of high strength, and as shown in FIG. 1, the first chromakey screen 10 is in an upright state, The first and second chromakey screens 10 and 30 are fixed by inserting both ends into the first tube body 51 and the second tube body 53 in a state where the first and second chromakey keys 30 are laid horizontally.

Here, it is preferable that the connecting member 70 is fixed in a state where the first and second chromakey screens 10 and 30 are adjacent to each other.

In the first and second chromakey screens 10 and 30 fixed by the connecting member 70, the lower portion of the first screen 13 provided on the first chromakey screen 10 is connected to the second chromakey screen 10, Is positioned on the upper surface of the second screen (33) of the second housing (30).

The first and second screens 13 and 33 have a double structure in which a chroma key fabric for photographing and a white fabric are laminated. The first and second screens 13 and 33 shown in FIGS. 1 and 2, Is a chromakey fabric. In Fig. 3, the folded and abutted surface is a chromakey fabric.

The locking means 90 comprises a latch 91 formed at the upper center of the first chromakey frame 11 and a latching end 93 formed at the center of the left end of the second chromakey frame 11.

As shown in FIG. 3, when the portable double-sided chromakey screen 100 is installed without extending the floor, the second chromakey screen 30 is locked from the connection member 70 in the unlocked state, The other end of the connecting member 70 which is coupled to the first chromakey screen 10 by the means 90 and is not connected to the first chromakey screen 10 of the connecting member 70 is connected by the second connecting member 40 .

The other end of the connecting member 70 is coupled to the cap 20.

As shown in FIG. 8, the portable double-sided chromakey screen 100 according to the present invention having the above-described configuration can be easily and removably attached to the camera 100 by a video camera 300 such as a camera or a video camera. .
