Description

The present invention relates to a beverage production glass that simultaneously and accurately projects an image transmitted through the beverage glass and an image reflected by a reflector in the beverage glass, and a storage medium used for the beverage production glass.

Glasses with various functions other than the function of putting beverages have been developed, and a beverage production glass with a reflector placed inside the glass and a beverage production glass that cancels image distortion due to the lens effect of the beverage have been developed. ing.
For example, Patent Document 1 discloses a drinking glass produced by the inventor of the present application.

It is a glass that can be.

Patent No. 6488049 Patent No. 6479668

However, the beverage production glass of Patent Document 1 causes a problem when the reflected image reflected in the glass and the transmitted image transmitted through the glass are visually recognized at the same time. It is normal for the user because when the user sees the glass body from a position where the transmitted image and the reflected image can be visually recognized at the same time (for example, the upper side of the side surface of the glass), one of the images is turned upside down. The problem is that you can't watch the movie. In particular, when the image of the video display device is a character image, one of the characters of the transmitted image and the reflected image is inverted and becomes unreadable, which causes a very big problem.
Since the beverage production glass of Patent Document 2 outputs a laterally compressed squeeze image for canceling the distortion of the transmitted image transmitted through the glass body from the image display device, the inside of the glass is tentatively described in Patent Document 1. When the reflecting mirror is arranged in this way, the reflected image of the reflecting mirror is crushed in the lateral direction by the squeeze image, and there is a problem that the user cannot accurately see the reflected image.

In view of the above problems, the present invention provides a beverage production glass in which the reflected image reflected in the glass body and the transmitted image transmitted through the glass body can be visually recognized by the user at the same time without being turned upside down. That is the issue.
Another object of the present invention is to provide a storage medium containing a program used for the beverage production glass.

The drinking effect glass of the present invention has a glass body which is a bottomed tubular body having an upper opening, a fixing mechanism for fixing an image display device to the side surface of the glass body, and an image display of the image display device. A transparent portion for visually recognizing the surface from the outside of the glass body, a first display area for displaying a transmission image, a second display area for displaying a vertically inverted image, the first display area and the second display. The image display area control unit for controlling the position of the area and the reflecting mirror arranged inside the glass body are provided, the reflecting mirror is provided with at least one layer made of metal, and the image display surface is the first. The image display area control unit includes one display area and the second display area, and the image display area control unit includes a boundary line position control unit that changes the position of the boundary line between the first display area and the second display area, and the upside-down image. Is reflected by the reflecting mirror and reflected in the direction of the upper opening, and the transmission image is characterized by passing through the beverage in the glass body and the transparent portion and reaching the outside of the glass body.
Further, the boundary line position control unit is characterized by being computer software or a computer program that controls or changes the position of the boundary line.
Further, the image display area control unit is mounted as computer software or a computer program in a computer inside or outside the housing of the video display device.
Further, the transparent portion is curved in a convex shape toward the outside of the glass body.
It is characterized by including an image aspect ratio control unit for outputting a squeeze image obtained by compressing the transmission image in the horizontal direction to the first display area.
Further, the image aspect ratio control unit is a Fresnel lens in which a Fresnel lens pattern is embossed on the surface of the transparent portion.
Further, a band image having a rectangular shape is displayed at the position of the boundary line, the band image has a certain height or width, and the band image is an image composed of a monochromatic color or a repeating pattern of a specific pattern. It is characterized by that.
The recording medium of the present invention is a storage medium in which a computer program used in the beverage production glass is stored, and the computer program acquires the position and / or size of the first display area on the video display surface from the computer memory. Then, the computer program acquires the position and / or size of the second display area on the video display surface from the computer memory, the computer program displays the transparent image in the first display area, and the computer. The program is characterized in that the vertically inverted image is displayed in the second display area.
Further, the computer program acquires the position and / or size of the first display area on the video display surface from the computer memory, and the computer program obtains the position and / or size of the second display area on the video display surface. The computer program displays the transparent image in the first display area, the computer program displays the vertically inverted image in the second display area, and the computer program displays the boundary. It is characterized by changing the position of the line.
Further, the computer program is characterized in that the squeeze image is displayed in the first display area.
Further, the computer program is characterized in that the band image is displayed at the position of the boundary line.

In the drinking glass of the present invention, the image of the image display device on the side surface of the glass body can be divided into a transmission image transmitted through the transparent portion of the glass body and a reflection image reflected by the reflector inside the glass body. In addition, since the video display surface has an independent first display area (displaying a transparent image) and a second display area (displaying a vertically inverted image), the user simultaneously or alternately displays a transmitted image and a reflected image. It is possible to seamlessly switch to and visually recognize. Moreover, the reflected image and the transmitted image are never visually recognized upside down.
The beverage effect glass of the present invention allows the position of the boundary line between the first display area (displaying a transmissive image) and the second display area (displaying an upside down image) to be changed or controlled by computer software or a computer program. Therefore, it is possible to support various sizes of image display devices and reflectors without changing the fixed position of the image display device. Further, even if the angle between the reflector in the glass body and the bottom surface of the glass body (or the angle between the reflector and the image display surface) is changed, it is possible to respond immediately.
In the effect glass for beverages of the present invention, the image display surface has a first display area (for displaying a transmissive image) and a second display area (for displaying an upside-down image) independently. Even if a squeeze image (horizontally compressed image) that cancels the distortion caused by the lens effect of the beverage is used for the image displayed in the first display area (transmission image), the upside-down image displayed in the second display area is not affected. Therefore, the user can simultaneously visually recognize the reflected image and the transmitted image having an accurate aspect ratio (English: abstract ratio).
The beverage effect glass of the present invention has a certain width (or height) at the position of the boundary line between the first display area (displaying a transmissive image) and the second display area (displaying an upside-down image). By displaying a monochromatic band image in the shape of a rectangle, the user does not have to completely match the height of the top edge of the reflector inside the glass body with the height of the top edge of the second display area. Since it is possible to avoid a situation in which a part of the transmission image is reflected in the reflected image (upside-down inverted image) visually recognized from the upper opening of the glass body, the user can comfortably view only the reflected image.

[First Embodiment of Beverage Production Glass]
Hereinafter, the first embodiment of the beverage production glass of the present invention will be shown with reference to the drawings.
As shown in FIG. 1, the beverage effect glass 1 has a glass body 10 which is a bottomed tubular body having an upper opening 11, a fixing mechanism 15 for fixing the image display device 80 to the glass body 10, and an image display device. A transparent portion 12 for visually recognizing the image display surface 81 of the 80 from the outside, a first display area 82 for displaying the transparent image 90, a second display area 83 for displaying the vertically inverted image 91, and a first display area 82. It is roughly composed of an image display area control unit 85 that controls the position of the second display area 83, and a reflector 30 arranged inside the glass body 10.
The glass body 10 is a bottomed tubular body having an upper opening 11, and examples of the shape of the glass body 10 are a normal cup-shaped shape as shown in FIG. 1 (a) and a normal cup-shaped body as shown in FIG. 5 (a). A beer mug type (or mug type) shape having a handle 13 and a bottle type shape having a lid for closing the upper opening 11 as shown in FIG. 5 (b) can be mentioned. Examples of the material of the glass body 10 include glass and resin. The inside of the glass body 10 is filled with the beverage L.
The fixing mechanism 15 is a fixing mechanism for fixing the image display device 80 to the glass body 10, and in the example of FIG. 1A, a storage unit provided in the glass body 10 is used as the fixing mechanism 15. The fixing mechanism 15 may use any kind of fixing mechanism as long as the image display device 80 can be fixed to the glass body 10, and the fixing mechanism 15 may use a combination of a screw mechanism, a suction cup mechanism, or the like. The material of the fixing mechanism 15 is not particularly limited, but a transparent material is desirable so as not to block the image display surface 81 of the image display device 80.
The transparent portion 12 is a transparent area provided on the side surface of the glass body 10 so that the image display surface 81 of the image display device 80 can be visually recognized from the outside. Examples of the material of the transparent portion 12 include transparent glass and a transparent resin such as acrylic. The user U visually recognizes the image (strictly speaking, the transmission image 90) reflected on the image display surface 81 of the image display device 80 through the beverage L inside the glass body 10 through the transparent portion 12 from the outside of the glass body 10. .. The broken line P1 in FIG. 1A is an illustration showing an image of the optical path P1 of the light projected from the transmission image 90 for explanation, and the transmission image 90 is the beverage L as in the optical path P1. It penetrates (or passes through) the transparent portion 12 and reaches the outside of the glass body 10.
The reflector 30 is a member for reflecting an image (more accurately, an upside-down image 91) reflected on the image display surface 81 of the image display device 80 toward the upper opening 11 of the glass body 10, and is a member for reflecting the reflector 30. Is arranged inside the glass body 10. The broken line P2 in FIG. 1A is an illustration of the optical path P2 image of the light projected from the vertically inverted image 91 for the sake of explanation. The user U can visually recognize the vertically inverted image 91 reflected by the reflecting mirror 30 from the upper opening 11. The reflecting mirror 30 may be any ordinary mirror made of aluminum, stainless steel or the like having at least one layer made of metal. However, it is prohibited to use a mirror (that is, a mirror made of a translucent dielectric) such as a half mirror or a beam splitter that allows a part of the incident image to pass through behind as the reflecting mirror 30. Because these translucent mirrors transmit the upside-down image 91 that should be reflected behind it, so not only the transmission image 90 but also the upside-down image 91 (semi-transparent ghost image) is displayed on the side surface of the glass body 10. This is because the image is captured (in such a state), and as a result, the user U cannot comfortably see only the transparent image 90. Therefore, the reflecting mirror 30 must be a mirror having at least one layer made of metal (to prevent the transmission image 90 from being transmitted behind).
As shown in FIG. 1A, the image display surface 81 of the image display device 80 is composed of a first display area 82 for displaying the transmission image 90 and a second display area 83 for displaying the vertically inverted image 91. The area displaying the second display area 83 in the image display surface 81, that is, the vertically inverted image 91 (in the example of FIG. 1A, the vertically inverted character image of A is used) is the reflection in the glass body 10. Since the mirror 30 reflects the image while flipping it upside down in the direction of the upper opening 11, the user U is on the side of the upper opening 11 (more strictly, on the side where the image display device 80 can be seen through the glass body 10) as shown in FIG. 1 (b). Moreover, the reflected image 93 of the upside-down image 91 visually recognized from the upper opening 11 side) is an image in a normal state where it is not upside down (that is, a normal character image of A which is not upside down as shown in FIG. 1B). become. Therefore, from the viewpoint of the user U outside the glass body 10, the transmission image 92 (transmission image 90) transmitted through the transparent portion 12 and the reflection image 93 (upside-down inverted image 91) reflected by the reflecting mirror 30 are not vertically inverted from each other. (That is, the user U can visually recognize both the transmission image 92 and the reflection image 93 as accurate images that are not turned upside down).
The image display area control unit 85 is used to control the positions of the first display area 82 and the second display area 83. The image display area control unit 85 includes a boundary line position control unit 86 that controls or changes the position of the boundary line 84 between the first display area 82 and the second display area 83.
The image display area control unit 85 and the boundary line position control unit 86 may be embedded in the bottom surface of the glass body 10 or inside the housing of the image display device 80 in the form of a dedicated IC, an ASIC, or the like. Further, it may be mounted as computer software or a computer program in a computer inside or outside the housing of the video display device 80. In an extreme case, the image display area control unit 85 and the boundary line position control unit 86 may be implemented as cloud software or an ASP in a server computer at a remote location. The image display area control unit 85 may include a computer memory for storing an upside-down image 91 and a transmission image 90 inside the image display area control unit 85.

A supplementary explanation will be given for the first display area 82 and the second display area 83.
In the beverage effect glass 1 of the present invention, the height h1 from the bottom surface of the glass body 10 to the upper end of the second display area 83 and the glass body 10 are increased in order to enhance the comfort when the user U visually recognizes the upside-down image 91. It is desirable that the height h2 from the bottom surface of the mirror 30 to the upper end portion of the reflecting mirror 30 be equal (or almost equal) as shown in FIG. 1 (a). This is because if h1 <h2 as shown in FIG. 2A, the reflecting mirror 30 reflects not only the vertically inverted image 91 but also a part of the transmission image 90, so that the user U can see through the upper opening 10. Looking at the reflector 30, in addition to the upside-down image 91 as shown in FIG. 2B, a part of the transmission image 90 (originally the transmission image 92) protrudes and is visually recognized, and the upside-down image 91 is very large. This is because it becomes difficult to see. However, the height h2 can be easily changed by simply changing the angle a1 formed by the reflecting mirror 30 and the bottom surface of the glass body 10 (as shown in FIG. 3A) or replacing it with a reflecting mirror 30 of another size. Similarly, the height h1 can be easily changed by simply replacing it with another video display device 80 (as shown in FIG. 3B). Therefore, in the beverage effect glass 1 of the present invention, h1 = h2 can be set so that the size of the reflector 30 and the angle a1 can be changed (that is, the fixed position of the image display device 80 is not changed). ), The boundary line position control unit 86 for controlling or changing the position of the boundary line 84 between the first display area 82 and the second display area 83 is provided.
The boundary line position control unit 86 may be implemented as computer software or a computer program that changes the positions of the boundary line 84 of the first display area 82 and the second display area 83. The merit of this method is that the size of the reflector 30 and the size of various commercially available video display devices are registered in the database in the computer software in advance, so that the video display device used as the video display device 80 can be stored in the database. It is possible to automatically change the position of the boundary line 84 so that h1 = h2 (and without changing the default fixed position of the image display device 80) simply by selecting from.
By combining the height h2 value with a camera sensor that can be automatically acquired by image analysis, the value that makes h1 = h2 even when the angle and size of the reflector 30 or the size of the image display device 80 is changed is automatically calculated. You may be able to do it.

When adjusting the angle a1 formed by the reflector 30, it may be difficult to completely equalize h1 and h2 visually or manually. As a solution in that case, as shown in FIG. 4 (a), a rectangular band image 87 having a constant height (or width) is displayed at the position of the boundary line 84, as shown in FIG. 4 (b). As described above, a method of hiding (covering) a part of the transparent image 90 reflected on the reflecting mirror 30 can be considered. The band image 87 is a monochromatic image that serves as a letterbox that separates the images. As shown in FIG. 4A, the height h3 of the band image 87, the height h1 from the bottom surface of the glass body 10 to the upper end of the second display area 83, and the bottom surface of the glass body 10 to the upper end of the reflector 30. As long as the height h2 is within the range of h1 ≤ h2 ≤ h1 + h3, the band image 87 is placed at the position where the transparent image 90 on the reflector 30 is reflected as shown in FIG. 4 (b). In order to capture the image (in other words, the band image 87 can completely cover the transmission image 90), the user U can see only the reflection image 93 (upside down image 91) from the upper opening 11. Therefore, even if the angle adjustment of the angle a1 formed by the reflecting mirror 30 is slightly deviated, the user U can visually recognize only the reflected image 93 (vertically inverted image 91) from the upper opening 11.
The band image 87 is preferably an image that does not bother the user U even if it is turned upside down, for example, an image consisting of a single color or a repeating pattern of a specific pattern.

Since the glass body 10 is a bottomed tubular body like a normal glass or beer mug, the shape of the beverage L inside the glass body 10 is inevitably a cylinder as shown in FIGS. 1 (a) and 6 (a). Shaped or almost cylindrical. Since the cylindrical shape is not curved in the vertical direction, the radius of curvature in the vertical direction of the beverage L can be regarded as infinite. On the other hand, since the beverage L is curved in a circular shape in the horizontal direction, the horizontal curvature radius RH always has a finite value as shown in FIG. 7 (in the case of a glass of a normal size, the horizontal curvature of the beverage L). The radius RH is about several [cm] to 10 [cm]). Since the refractive index of the light of water is about 1.333, which is larger than the refractive index of the light of air, the image transmitted through the water or the beverage L having a cylindrical diameter is horizontally as shown in the transmission image 92 of FIG. It is stretched and enlarged. This is because the cylindrically shaped beverage L acts as a light refraction medium and functions in the same manner as a convex lens (strictly speaking, a biconvex lens) (for details of the biconvex lens, refer to a technical book on optics or a lens). Therefore, as shown in FIG. 6A, the width W2 of the transmission image 92 transmitted through the beverage L is larger than the W1 of the transmission image 90 (that is, the transmission image 92 is an image obtained by enlarging the transmission image 90 by some percentage in the horizontal direction). become).
As a person who enables the user U to visually recognize the transmission image 92 maintaining the same original aspect ratio (English: compression ratio) as the reflection image 93, the transmission image 90 is preliminarily placed in the horizontal direction as shown in FIG. 6 (b). A method using an image aspect ratio control unit 100 that outputs the compressed squeeze image 94 to the first display area 82 can be considered. Since the squeeze image 94 previously compressed in the horizontal direction as the transmission image 90 by the image aspect ratio control unit 100 is output to the first display area 82, the user U has the original aspect ratio of both the transmission image 92 and the reflection image 93. It becomes visible while maintaining the aspect ratio).
As the algorithm for generating the squeeze image 94 compressed in the horizontal direction, a known algorithm built in the LD playback device, the DVD playback device, or the photo retouching software may be used.
There is one caveat: the squeeze image must never be displayed in the second display area 83. The second display area 83 is an area projected by the reflector 30 toward the water surface of the beverage L, and since the water surface is flat and not curved, the lens effect of the beverage L hardly occurs. Therefore, if a squeeze image is displayed in the second display area 83 (similar to the first display area 82), the reflected image 93 seen by the user U becomes a distorted image compressed in the horizontal direction.
In the beverage effect glass 1 of the present invention, since the first display area 82 and the second display area 83 are independent, the user U maintains the original aspect ratio (English: aspect ratio) of both the transmission image 92 and the reflection image 93. It becomes visible without distortion.
As shown in FIG. 8, there is a method of using the Fresnel lens 20 in which the pattern of the Fresnel lens is embossed on the surface of the transparent portion 12 as the image aspect ratio control unit 100.
Since the Frenel lens 20 can control the magnification of the vertical image and the magnification of the image in the horizontal direction by changing the pattern of the Frenel lens, the transmission image 92 can be compressed in the horizontal direction (that is, the transmission image 92 itself). Can be made into a squeeze image). The merit of this method is that the weight of the beverage production glass 1 can be reduced because the IC for the image aspect ratio control unit 100 and the computer do not need to be mounted on the glass body or the image display device 80, and the squeeze image can be displayed by software or a computer program. Since it is not a generation method, it does not consume computer resources. Further, as another merit, since the Fresnel lens 20 has no thickness and weight unlike a normal convex lens, the weight of the transparent portion 12 is higher than that when the convex lens is mounted on the transparent portion 12 as the image aspect ratio control unit 100. It is possible to reduce the thickness of the lens. To give a supplementary explanation about the Frenel lens, a Frenel lens is a lens made by engraving or embossing a pattern of a Frenel lens such as a concentric circle on the surface of a transparent object. (For more details on Fresnel lenses, please refer to the specialized books on optics and Fresnel lenses). As shown in FIG. 8, the Fresnel lens 20 is arranged on the transparent portion 12 on the side opposite to the image display device 80 (that is, on the user U side) and the transparent portion 12 between the image display device 80 and the beverage L. (In either arrangement method, the Fresnel lens 20 completely operates as the image aspect ratio control unit 100).
