Description

Holographic Imaging Device for Advertising {HOLOGRAM IMAGING DEVICE}

The present invention relates to an image device, and more particularly, an advertisement can be viewed in any direction by forming a three-dimensional screen member that can output an image generated by the image generating device and at the same time view a rear object. It relates to a holographic imaging device for advertising to maximize the effect.

In general, an advertising video apparatus employs a method of displaying an image using a light emitting diode and a method of projecting an image on an ultra-large screen.

However, the conventional image output apparatus requires expensive production cost, and the uniformity of the image output is degraded because the projected image is very sensitive to changes in the external environment and changes in the brightness of the sun or the light.

A hologram screen is used to improve the above point and to view the rear object on which the image is projected.

In the hologram screen, most of the amount of light projected from the projector set to be suitable for the diffraction conditions of the hologram is deflected in a predetermined direction, and most of the amount of light from an object which is not suitable for the diffraction conditions of the hologram can be transmitted as it is.

However, since the hologram screen projects the image on a single plane, the exposure effect of the advertisement is lowered because the image is not observed to the person on the side or the back of the projection surface.

In addition, installation and maintenance costs are increased by installing a projector for each projection surface of the hologram screen. Therefore, there is a need for improvement.

In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or convention of a user or an operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

1 is a perspective view of an advertising holographic image device according to an embodiment of the present invention, Figure 2 is a side view of the advertising holographic image device shown in FIG.

Advertising hologram imaging device according to an embodiment of the present invention, the screen member (1) is formed of a transparent material and outputs only the image incident at a set angle, and the screen member (1) is installed around the circumference and installed in various directions It comprises a three-dimensional image unit 10 for viewing the advertising image and the image generating device for sending an image to the screen member (1) surrounding the three-dimensional image unit 10.

The image generating apparatus includes a projector 20 for irradiating an image to the screen member 1 or an image output member 19 for outputting an image on its own screen.

The projector 20 irradiates an image on the front screen 27, and the image irradiated on the front screen 27 is transmitted to the screen member 1 again to form an image on the screen member 1 formed of a half mirror material. Is displayed.

In an embodiment of the present invention, an image output member 19 is used as the image generating device.

The image output member 19 refers to various image devices for outputting an image on its own screen, including a flat-panel television, and the image of the image output member 19 is transmitted to the screen member 1 installed at a short distance to the image. Will print

When the image output member 19 is used as the image generating apparatus, the size of the stereoscopic image unit 10 is small and installed in a small space. When the projector 20 is used as the image generating apparatus, the stereoscopic image is used. The image unit 10 is large and is used when installed in a large space.

The screen member 1 displays only an image incident at a set angle, and the image incident at other angles passes through the screen member 1.

Therefore, only the image incident on the screen member 1 at the set angle is displayed among the images output to the image output member 19, and the shape of the object behind the screen member 1 is the screen member ( Passing 1) allows observation with the image.

In the technical concept as described above, the screen member 1 may be molded in various shapes and materials. According to one embodiment of the present invention, the screen member 1 uses a half mirror.
