Description

The present invention provides clear photographic data without shadows when a camera is used to photograph a paper medium on which predetermined information is printed, such as a photographing table, more specifically, a receipt or receipt. It relates to a camera stand that can obtain

In the economic society where digital transformation is progressing, the revision of the electronic book storage law enforced in January 2022 has improved productivity by digitizing accounting, promoting telework, and going paperless. For this reason, companies that provide accounting software and the like provide services for optically reading receipts and other forms and providing various types of information to financial systems based on the read images.

Under such circumstances, even users who are unfamiliar with IT have no choice but to utilize accounting software when developing a business. For this purpose, it is necessary to have a function that can easily take a picture of a receipt, which is a paper medium issued when a product is purchased from a retail store, and provide various information to the financial system. However, when a receipt is simply photographed with a camera, the receipt may curl depending on the length of the receipt, and the receipt may be out of focus, making it difficult to obtain necessary information from the photographed image data. could not. In addition, shadows were generated during photographing, and necessary information could not be obtained from the presence of these shadows.

Japanese Patent Laid-Open Nos. 2003-100001 and 2004-100000 propose a photographing stand that can optically read a paper medium and provide various information to a financial system based on the read image.

In both of the techniques described in Patent Documents 1 and 2, a paper medium such as a receipt is placed on a placement table, and the table is covered with a cover. Then, according to the technique disclosed in Patent Literature 1, the portable terminal device photographs a paper medium through a photographing hole provided in the terminal placement portion. In the technique disclosed in Japanese Patent Laid-Open No. 2002-200020, the covered document is sent to the page-turning reading device of the scanner.

The technique described in Patent Document 1 is simple in terms of photographing a paper medium using a portable terminal, but the device is large, and it is troublesome to photograph a small amount of receipts. Instead, it is necessary to move to the place where this device is placed and take a picture of the receipt, so it is hard to say that it is convenient.
In addition, the technique described in Patent Document 2 requires a separate scanner, which is not very convenient.

Therefore, the inventor paid attention to shadows that occur during photographing, and colored the placement member on which the paper medium is placed in a color other than white, and sandwiched the paper medium between the placement member and the cover member. The present invention has been completed based on the finding that by photographing, with a simple structure, the recognition efficiency of character information when photographing is increased, and various information can be accurately read from the photographed data.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a photographing table which has a simple structure and can accurately read information from photographed data obtained by photographing a paper medium on which various information is printed.

The invention according to claim 1 is a flexible sheet-like photographing sheet used when photographing a paper medium on which predetermined information is printed using a camera, the photographing sheet being colored in a color other than white. and a transparent and colorless cover member having a predetermined thickness. By bending a cover member, the cover member and the information printing surface of the paper medium are in contact with each other, and the camera is used to photograph the paper medium.

According to the first aspect of the invention, a paper medium on which predetermined information such as a receipt is printed is sandwiched between the cover member and the mounting member, and the paper medium is photographed using a camera. The cover member is made of a colorless and transparent plate material, and the placement member is colored in a color other than white. In general, since the receipt is white, by coloring the placement member in a color other than white, a contrast is generated between the receipt and the other portions. By doing so, it is possible not only to prevent shadows from occurring at the time of photographing, but also to accurately read various information from photographed data obtained by photographing.

Regarding the coloring of the mounting member, it is preferably a dark color, that is, a color having a large contrast with respect to white or a light color, preferably a primary color such as black, green, red, or blue. It is preferable that the mounting member is colored green, because the color that can achieve the effect is green. However, since a dark color causes reflection of external light, the mounting member may be colored in a light color, and the surface and/or the back surface of the cover member may be subjected to low-reflection processing. Methods of low-reflection processing include physical and chemical surface treatment, application of coating agents, and application of low-reflection films. Also, a material having a low reflection function may be used as the material of the cover member.

The material, thickness, hardness, and size of the mounting member and the cover member are not particularly limited as long as they do not create shadows when photographed. A4 size and thickness of 0.1 mm to 1.5 mm are preferred. The hardness is not particularly limited as long as the placement member and the cover member can be stacked and bent by hand, because photography is possible. Due to the flexibility, air bubbles do not enter between the placement member and the cover member when the device is held in the hand during shooting. Imaging data increases the visibility efficiency of character information. In particular, in the case of a paper medium with folds, it is difficult to focus on the entire paper medium when the paper medium is held in hand and photographed, making it difficult to visually recognize character information from the imaged data. However, according to the present invention, since the cover member and the placement member have flexibility, the paper medium is sandwiched between the cover member and the placement member, and the cover member and the placement member are bent. Since the placement member can be brought into tighter contact, the visibility efficiency can be improved, which is effective.

The invention according to claim 2 is the photographing stand according to claim 1, wherein the cover member is subjected to low-reflection processing.
When the mounting member is dark-colored, external light is reflected. Therefore, the surface and/or the back surface of the cover member should be subjected to low-reflection processing to prevent external incident light from being captured in the photographed data. can be done.
Methods of low-reflection processing include physical and chemical surface treatment, application of coating agents, and application of low-reflection films. Also, a material having low reflectivity may be used as the material of the cover member.

Note that the cover member may be divided into a plurality of parts. In this case, since the cover member is divided into two or more pieces, a part of the cover member is used to clip the paper medium to temporarily fix the paper medium, and then the remaining cover member is used to clip the paper medium. A medium can be sandwiched. As a result, even if the paper medium is thin, the photographed data can be acquired without damaging the paper medium.

According to the present invention, a paper medium on which predetermined information such as a receipt is printed is sandwiched between the cover member and the placing member, and the paper medium is photographed using a camera. The cover member is made of a colorless and transparent plate material, and the placement member is colored in a color other than white. As a result, contrast is created between the paper media such as receipts and other parts, and not only is there no shadow when shooting, but various information can be accurately read from the shooting data obtained by shooting. becomes possible.

In particular, according to the second aspect of the invention, when the mounting member is colored in a dark color, external light is reflected. It is possible to prevent the incident light from being taken into the photographed data.

(b) is a perspective view showing the state of the imaging stand when photographing a paper medium using the imaging stand according to the first embodiment of the present invention. FIG. 10 is a perspective view showing a photographing stand according to Example 2 of the present invention;

(Example 1)
Embodiment 1 A photographing stand according to Embodiment 1 of the present invention will be described with reference to the drawing (FIG. 1(a)). The photographing stand has a rectangular shape in plan view, and is made of A5 size resin (clear file). The photographing table is integrally formed with a mounting member 11 whose entirety is colored in a color other than white, and a colorless and transparent cover member 12. - 特許庁That is, the photographing table is constructed by folding a sheet of rectangular film and coating (or pasting colored paper on) only the mounting member with paint. It should be noted that the mounting member 11 and the cover member 12 may be formed of separate members, and may be configured to be openable and closable by adhering the ends of both members with a tape or the like.

A paper medium is photographed using the photographing stand configured as described above. First, the paper medium 100 is placed on the placement member 11 . At this time, the surface of the paper medium 100 to be photographed faces upward. Next, the cover member 12 is folded to bring the cover member 12 and the upper surface of the paper medium 100 into contact with each other. After that, the imaging table is held and bent by hand. After that, the camera is focused, photographed, and imaged data is obtained.

At this time, the test was performed using four colors of the mounting member 11, ie, white, light blue, green, and black. As a result, in the case of white, it was found that it was difficult to distinguish between the paper medium 100 and the mounting member 11 from the imaging data, and that there was an area in which it was difficult to recognize the information printed on the paper medium 100. did.
When the placement member 11 was light blue, green, or black, the paper medium 100 was not shaded and the information printed on the paper medium 100 could be clearly recognized.
However, when the color of the mounting member 11 is green or black, the reflected light of the external light is reflected in the imaging data. Therefore, when a low-reflection film was attached to the surface of the cover member 12 and another photograph was taken, the reflected light of the external light was suppressed, the shadow did not appear on the paper medium, and the information printed on the paper medium was clearly visible. It was possible to recognize

(Example 2)
As shown in FIG. 2, the photographing allowance according to the second embodiment is divided into two rectangular cover members 22A and 22B so that the ratio of the length in the longitudinal direction is about 1:3. The cover member (cover A member 22A) having the shorter length is attached with a hinge so that it can be folded around the short side of the placing member. The longer cover member (cover B member 22B) is attached with a hinge so that it can be folded around the long side of the placement member.

A paper medium is photographed using the photographing stand configured in this manner. First, a paper medium is placed on the placement member 21 . After that, the cover A member 22A temporarily fixes the paper medium by clipping it, and then the cover B member 22B sandwiches the paper medium to fix the paper medium.
By doing so, even if the paper medium is thin or deteriorated significantly, it is possible to photograph without damaging the paper medium. However, even if the cover A member 22A and the cover B member 22B were made of the same material and had the same thickness, the boundary between the cover A member 22A and the cover B member 22B could be seen from the imaging data. However, since there was no problem in reading the information, it was possible to clearly recognize the information printed on the paper medium without any particular problem.
Since other configurations are the same as those of the first embodiment, description thereof will be omitted.
