Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a screen image processing device that projects an image on a screen with a projector.

[0002]

[Prior art]

 Conventionally, an opaque screen is installed, for example, on the aisle side of a store or on a window glass part of a venue, and a projector installed in the store or the venue is used to transmit information video by a screen information transmitting device such as a VCR, a TV tuner, or a computer. Projecting is being done.

[0003]

[Problems to be solved by the invention]

 Customers outside the store or outside the venue can see the information video, but cannot see the background scene inside the store or the venue.

According to the present invention, an information image and a background scene image of a background scene can be simultaneously displayed on a screen, and different information images can be seen in the background scene as if they were floating in the air. It is an object of the present invention to provide a screen image processing device capable of performing the above.

[0005]

[Means for Solving the Problems]

 Means of the present invention for solving the above problems include a screen, a projector for projecting an image on the screen, a screen information transmitting device for transmitting information to the screen, and a background for photographing a background scene behind the screen. A scene photographing device, and a video information signal mixing device that mixes an information video signal of the screen information transmitting device and a background scene video signal of the background scene photographing device and transmits a mixed video signal to the projector. The information video signal from the screen information transmitting device and the background scene video signal from the background scene photographing device are mixed by the video information signal mixing device, and the mixed video signal is projected on the screen by the projector.

[0006]

[Embodiment of the invention]

 One embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, an opaque screen 3 is provided on a window glass 2 of a wall 1. In the store 4 and the like, a projector 5 for projecting an image on the screen 3 and a background scene photographing device 7 such as a video camera for photographing a background scene 6 of the store 4 and the like are installed. In the store 4 or a place farther from the store 4 or the like, a screen information transmitting device 8 such as a video deck, a TV tuner, or a computer for transmitting information to the screen 3, and an information video signal of the screen information transmitting device 8. A video information signal mixing device 9 for mixing the background scene photographing device 7a with the background scene photographing signal 7a of the background scene photographing device 7 is provided. Then, the mixed video signal 9 a of the video information signal mixing device 9 is transmitted to the projector 5.

Therefore, the information video signal 8 a of the screen information transmitting device 8 is transmitted to the video information signal mixing device 9, and the background scene 6 of the background scene 6 photographed by the background scene photographing device 7 is converted into a video information signal. It is sent to the mixing device 9. The video information signal mixing device 9 mixes the information video signal 8a and the background scene video signal 7a and sends the mixed video signal 9a to the projector 5. As a result, a mixed video of the mixed video signal 9a in which the information video signal 8a and the background scene video signal 7a are mixed is displayed on the screen 3 by the projector 5.

Thus, as shown in FIG. 2, the customer outside the store 10 can view the information video 11 by the information video signal 8a and the background scene video 12 of the background scene 6 by the background scene video signal 7a. . In this case, to the customer, the information image 11 which is a different image in the background scene image 12 appears to be floating in the air.

[0009]

[Effect of the invention]

 The present invention provides a screen, a projector for projecting an image on the screen, a screen information transmitting device for transmitting information to the screen, a background scene photographing device for photographing a background scene behind the screen, and the screen information transmitting device. A video information signal mixing device that mixes the information video signal of the device and the background scene video signal of the background scene photographing device and sends a mixed video signal to the projector; And the background scene image signal of the background scene photographing device are mixed by the image information signal mixing device, and the mixed image signal is projected on the screen by the projector, so that the information image and the background scene image of the background scene are simultaneously displayed. It can be projected on the screen, and different information images float in the air in the background scenery It can be seen as such.
