Advertising device using optical illusions {Advertising-Device Utilizing an Optical Illusion}

The present invention relates to an advertisement apparatus using optical illusion, and in particular, to install an advertisement board on a tunnel inner wall in which an electric car or a train runs, so that the advertisement billboard is visualized through the eyes of passengers in the means of transportation. It is.

In general, billboards are installed in trains and train stations or ticket offices, so that more people can see them, and these billboards are fixed means that display letters or pictures on the advertisement panel and display them by the light source behind the panel. This is mostly the case, especially in billboards where trains and trains pass.

In other words, in a place where the outside of the electric car is dark, even if the billboard could not be installed until now, there is no effort to use this space.

The present invention is intended to have an advertising effect by using the wall surface of the place, such as a dark tunnel while the electric car is running while driving.

The present invention provides a video advertising device as a new type, by adopting a flying support method which is a continuous motion method of the film to maximize the effect of advertising by making the film of the billboard look video.

The present invention removes the fine flicker phenomenon of the advertising screen caused by the slight up, down, shaking or swinging of the electric vehicle while driving, and at the same time makes the advertisement screen visible to the eyes of passengers in the electric car or train. I make it a problem.

The present invention has a technical problem of preventing the blurring of moving images in the advertisement screen so that the advertisement screen can be displayed more clearly.

The present invention is to use the idle surface and at the same time to reduce the overall installation costs, such as installation costs by a simple structure as a technical problem.

According to the present invention for achieving the above-mentioned problem, 40 frames are used as the advertisement screen unit at a predetermined interval, and the speed of the light source is 1/400 second, and the intensity of the light source is 100 times the illuminance that a human can see. Passing the frame is characterized in that it is configured so that one lighting and flashing successively per frame.

The present invention uses the light source of which the angle of view is greatly reduced while passing through the film at a constant speed to cause a flash phenomenon, so that the advertisement screen can be visually observed.

In other words, the present invention continuously processes one flash per frame and greatly increases the number of frames for one second to increase the lighting time of the light source, thereby increasing the critical fusion frequency of lighting and blinking.

The number of frames according to the present invention is theoretically 25 or more frames, but at least 36 frames or more films are used to produce a natural image phenomenon.

In addition, in order to correct the short lighting time, the intensity of the film projection light source is increased and at the same time, the flying support method is adopted to generate a moving image.

The present invention involves the following conditions.

First, the speed of the driving vehicle is 20m / sec or more, the driving vehicle must be a track vehicle, and the outside of the vehicle must be dark or at night while driving.

Second, if the speed of transportation is 20m per second and the horizontal length of one frame is 50cm, the number of frames moving for one second is 40. Then, one instant flash of light is projected per frame so that the flashing is continuously repeated 80 times for one second so that the duration per frame is 1/40 seconds.

Third, in order to prevent the drag of the image in the screen during the one-frame progress, that is, blur, the ratio of the advancing speed of the frame and the flash speed of the light source is adjusted to prevent blur of the image. In other words, the speed at which one frame advances is t1 (t1 is the time taken for the subject to move in one frame), and when the light source is instantaneously generated, that is, the shutter time is t2, the equation is as follows.

t1 / t2 = n1 ... (1)

In the above, n1 is a multiple of how many times the shutter speed is faster than the speed of one frame.

In the above formula (1), if the speed of t2 is 25 times faster than the speed of t1, that is, if the number n2 divided by t1 is greater than or equal to 25, the image blur does not appear substantially. Such a state exhibits the same effect as the stopping of the intermittent film.

If you rearrange it,

t1 / n1 = n2 ... (2)

In the above, n2 is the ratio of the blurring image on the screen in one frame.

Therefore, if the length L1 of one frame is multiplied by n2, the blur length L2 in one frame can be obtained. However, if the shutter speed is about 10 times the t1 speed, the blur can be corrected.

The following table summarizes the above formulas (1) and (2).

-Table-

Light source speed t1 / t2 = light source speed vs. subject speed magnification (n1) t1 / n1 = ratio of subject blurring image (n2) L1 × n2 = length of the subject blur image (L2) 1/100 second (1/40) (1/100) = 2.5 times (1/40) /2.5=1/100 500 × (1/100) = 5mm 1/200 sec (1/40) (1/200) = 5 times (1/40) / 5 = 1/200 500 × (1/200) = 2.5mm 1/400 sec (1/40) 1/400) = 10 times (1/40) / 10 = 1/400 500 x (1/400) = 1.25 mm 1/800 sec (1/40) (1/800) = 20 times (1/40) / 20 = 1/800 500 × (1/800) = 0.625mm 1/600 sec (1/40) (1/1600) = 40 times (1/40) / 40 = 1/1600 500 × (1/1600) = 0.313mm

As can be seen from the table, when the shutter speed is 1/400, that is, when the shutter speed is about 10 times the speed per frame, the image blur length is 1.25 mm and can be neglected.

Fourth, when the shutter speed reaches 10 times the one frame rate, the lighting time is extremely short, and the image becomes dark, which causes a problem in the moving image. Therefore, the intensity of the light source is determined to determine the correction value.

That is, the intensity determination value of the light source different from the shutter speed is

E = IT² ......................... (3)

In Equation (3), E is the amount of light energy, and the intensity (intensity) T of the light source is the total amount of time that light shines for 1 second.

For example, if the shutter speed is 1/400 sec and 40 frames, the total amount of time the light shines for 1 second is 1/10 second. Therefore, in order for the amount E of energy of light to have a constant value, the intensity I of the light source must be 100 times.

An embodiment of the present invention that can be implemented in accordance with such conditions will be described in detail with reference to the drawings.

According to the present invention, a window of an electric vehicle 3 driving an advertisement display unit 2 composed of a plurality of frames 2 'which causes the light source 1 to blink and light continuously repeatedly within the same time so that a screen is displayed. Several light sources 1 installed at an appropriate position of the wall surface A or other structure of the area where the observation is easy at 3 ', and installed in each frame 2' at an arbitrary position of the advertisement display unit 2; ) Installs an object detecting sensor 4 connected to the sensor, and installs a sensor detecting plate 5 at an arbitrary position of the electric vehicle 3 corresponding to the object detecting sensor 4, or at each train part of the electric vehicle 3. It is also possible to install the sensor detection plate 5, and to install the separate type to install the object detection sensor 4 for each frame (2 ').

In the above, the frame 2 'constituting the advertisement screen portion 2 is made of a transparent acrylic plate, and an advertising film 2 " and a film fixing acrylic plate 6 are installed on the rear surface of the acrylic plate. The back of the acrylic plate 6 is formed of a box in which the light source 1 is installed, and the number of the frames 2 'is 20 m when the traveling speed of the electric vehicle 3 is 72 km. The number of frames 2 'of the screen for the second is 40. Therefore, when observing the advertisement screen unit 2 in the moving train 3, 40 advertisement screens are displayed at a constant size and at regular intervals for one second. In the above, the advertisement film 2 "is represented by the same picture or the continuous picture which expresses the whole advertisement screen part 2 in one picture etc.

Since the light source 1 may generate heat at a high temperature by continuous flash operation, air generated from the electric vehicle 3 passing through the advertisement screen unit 2 is introduced into a box that is the advertisement screen unit 2. And a light source cooling passage 7 to be cooled so as to be cooled. Advertisement screen portion 2 having such a configuration should be protected from dust, have flexibility in the flow of air, and in principle, allow plastic injection resistant to collision.
