Description

Portable Apparatus for displaying hologram}

The present invention relates to a mobile hologram device, and more specifically, it is designed in the form of a bag to be carried on the shoulder or carried by hand, so that various images can be moved without regard to the place using the afterimage effect of the light emitting device. It relates to a device that can be displayed as an image.

With the development of information communication technology and display technology, the demand for a more realistic image image such as a 3D stereoscopic image is increasing, and the demand for a device for displaying it will increase dramatically.

In response to these demands, recent research on 3D video image reproduction technology has been actively conducted around academic and industrial fields at home and abroad, and the 3D video-related media is a new concept of realistic video media that raises the level of visual information to the next level. It is expected to lead the display.

The existing 2D display system provides a flat image, whereas the 3D display system is the ultimate image realization technology from the viewpoint of showing the actual image information of the object to the observer.

In order to reproduce such a three-dimensional stereoscopic image, stereoscopy, integrated imaging, and holography methods have been researched and developed.

The stereoscopic method mimics the human visual system, and the stereoscopic method separates the image into a left-eye image and a right-eye image, and then observes the left-eye and right-eye of an observer wearing glasses made of polarized liquid crystal panels. It is a way to make a 3D image feel by entering the image of.

The integrated image display method is largely divided into an image acquisition step (pickup) and an image playback step. The image acquisition step (pickup) consists of a two-dimensional sensor such as an image sensor and a lens array, where the three-dimensional object is located in front of the lens array. Then, various image information of the 3D object is stored in the 2D sensor after passing through the lens array. At this time, the stored image is used as a component image for 3D reproduction. Thereafter, the image reproduction step of the integrated image technology is an inverse process of the image acquisition step (pickup), and consists of an image reproduction device such as a liquid crystal display device and a lens array. Here, the element image obtained in the image acquisition step (pickup) is displayed on the image reproducing apparatus, and the image information of the element image passes through the lens array and is reproduced as a three-dimensional image image in space.

The holography method is a method in which when a holography produced by using a laser is observed, a stereoscopic image identical to a real object can be felt without wearing special glasses. Therefore, it is known that the holography method has an excellent three-dimensional effect and is the most ideal way for a human to feel a three-dimensional image without fatigue.

On the other hand, advertising is a method of delivering desired information or contents to a specific person or an unspecified person, and recently, it is one of the most important matters for a private company or a corporation.

These advertisements are carried out using various media such as airwaves, terrestrial waves, or printed materials. Existing print media advertisements (newspapers, magazines, flyers, etc.), video media advertisements (TV, radio, multicube, outdoor billboards, etc.) are all 2 This is done through dimensional media.

Advertising using 2D media is familiar to the public as it has become as common as it has been through its long history, but many businesses and companies use advertising to deliver the messages they want to the public. It is not easy to get attention. Therefore, it is necessary to first attract the public's attention and efficiently deliver the contents of the advertisement.

In other words, advertising needs to be able to focus the attention of the target group, then it is necessary to imprint the message you want to deliver to the individual, and if you can focus the public's attention, you will successfully carry out the first phase of advertising. .

To this end, Korean Registered Patent No. 10-0946319 outputs an image generated by an image generating device, and at the same time, a screen member capable of seeing an object at the rear is formed in three dimensions, so that the advertisement can be viewed in any direction. Although the technology of the hologram imaging device for advertising to maximize the size has been known, the screen member must be installed around the stereoscopic image unit and the image must be incident at the angle set on the screen member, so the installation of the screen member and the image generator is required. In order to ensure that sufficient space must be secured, there is a problem that there are restrictions on the place of use.
