Description

  The present invention relates to an attachment that is used by being attached to a camera-equipped mobile phone or a digital camera when imaging a standardized imaging object.

Business cards are personal information printed on paper or the like, and are generally stored and managed in a business card holder or the like. Also, if there are too many business cards to be managed, not only will it take up a place to store business cards, but it will also take time to search for business cards, so the names listed on the business cards Information such as company name and address is entered into a computer and managed. In this case, information written on a business card is generally taken into a computer by typing.
However, it takes a lot of time to input the information written on the business card, one by one, and the labor is excessive. Such a situation is not limited to a business card, but also applies to the case of typing in information written on a postcard in which an address is written, a paper on which a sentence is written, or the like.
In order to reduce such labor, a method using a digital camera or the like can be considered. In other words, if you take a business card or postcard with a digital camera or the like, capture the captured business card image data into a computer, and convert it into text data using the specified software, you can save time and effort for typing. Can be reduced.

Such business cards and the like can also be captured by a camera-equipped mobile phone. Here, the camera-equipped mobile phone is literally a mobile phone equipped with a camera. Such a camera-equipped mobile phone camera incorporates an image pickup means normally formed by a CCD (charge coupled device) in a case of a general mobile phone, and is exposed from a case at a predetermined position of the case. In such a state, a camera lens that guides image light to the imaging unit is provided.
The camera-equipped mobile phone can take a picture by such a configuration.
In particular, a camera-equipped mobile phone is usually carried around and can be taken easily anywhere, so it is very convenient. The image quality is also very good depending on the model.
In addition, if a function for converting image data such as captured business cards into character data is installed in the camera-equipped mobile phone in the future, the captured image data can be changed to character data on the camera-equipped mobile phone alone. It may be possible to use it.

However, since image pickup of business cards and the like is usually performed only once for each sheet, it is necessary to adjust the focus position for each sheet when capturing a plurality of business cards and the like.
In addition, camera phones and digital cameras, like handheld cameras, tend to pick up images from the object being picked up, so camera shake is likely to occur, and this camera shake adjusts the focus position. Hateful.
Furthermore, it is necessary to determine an imaging range so that captured image data can be automatically converted into character data, which is a troublesome operation.

  On the other hand, the shapes of business cards and postcards are standardized because they are standardized, and the preferred imaging range and focus position are common.

  From the above, if there is an attachment equipped with a means that can easily determine the imaging range and focus position, which is attached to a camera-equipped mobile phone or the like when imaging a standardized imaging object, Although it is considered that the above problems can be solved, it is preferable that such an attachment is portable and can be carried with a camera-equipped mobile phone or the like, and is compact and not bulky.

  Therefore, the present invention is an attachment that is used by attaching to a camera-equipped mobile phone or the like when imaging an imaging object standardized by a camera-equipped mobile phone or a digital camera. An object of the present invention is to provide an attachment having a compact configuration that can be easily determined.

The present invention is an attachment used by being attached to a mobile phone with a camera or a digital camera.
Note that the camera-equipped mobile phone to which the attachment of the present invention is attached need not be special. A general mobile phone with a camera or a digital camera may be used. For example, a case and an imaging unit that is built in the case and captures image light from an imaging target to be imaged, and is exposed from the case at least when imaging, A camera-equipped mobile phone or a digital camera may be provided that includes a camera having a camera lens through which the image light passes and is guided to the imaging unit. In addition, the “mobile phone” in this specification includes PHS.
In the attachment according to the present invention, the camera lens is exposed downward, the fixing member for detachably fixing the mobile phone with camera or the digital camera, and a part of the imaging object are arranged. A positioning auxiliary member that fixes an optical distance from the imaging object to the camera lens so that a focus position of the camera lens when in contact with a surface is located at an imageable position of the imaging unit. Have. The positioning assisting member has a part of which is in contact with the surface on which the imaging object is disposed, so that the imaging unit has an imaging range suitable for the imaging object having one standardized shape. The imaging range is determined. And the position with respect to the said fixing member of the said positioning auxiliary member when using this attachment is comprised so that it may differ from the position with respect to the said fixing member when not using the said attachment. It is configured so as to be substantially rod-shaped.

Thus, the attachment according to the present invention is configured such that the position of the positioning auxiliary member relative to the fixing member when using this attachment is different from the position relative to the fixing member when not using the attachment. Since it is configured to have a substantially card shape or a substantially rod shape, it is compact and easy to carry. That is, such an attachment can be carried with a camera-equipped mobile phone or the like.
In addition, by using this attachment, it is possible to easily determine the focus position and imaging range when imaging a standardized imaging object by attaching it to a mobile phone with a camera or a digital camera as necessary. it can.
Examples of the imaging object having a standardized shape include standardized paper such as business cards, postcards, A5, and A6. In addition, since the attachment of the present invention is for reducing labor when repeatedly imaging an imaged object having a standardized shape, the imaged object is a photograph that does not contain characters, a trading card, etc. It may be.

Here, “substantially card shape or substantially rod shape” is generally a shape that is easy to carry and is not bulky even if the thickness, height, and width are not constant. Means good.
That is, the fixing member and the positioning auxiliary member may have the same shape or different shapes.
Specifically, the thickest part of the attachment when not in use can be 5 mm, but if the upper limit is 10 mm, it is “substantially card-shaped or substantially bar-shaped”.

The fixing member may be any member as long as it can detachably fix the camera-equipped mobile phone or digital camera with the camera lens exposed downward.
The material of the fixing member can be made of resin. In this way, the attachment can be made lightweight.

The positioning object is positioned so that a focus position by the camera lens is located at an imageable position of the imaging unit when a part of the positioning auxiliary member is brought into contact with a surface on which the imaging object is disposed. The optical distance from the camera lens to the camera lens is fixed. The positioning assisting member determines the imaging range of the imaging means so as to be an imaging range suitable for an imaging object having a standardized shape.
That is, the positioning assisting member has a function of suppressing camera shake and a function of determining an imaging range. With such a positioning auxiliary member, when imaging a business card or the like with a camera-equipped mobile phone or digital camera camera to which an attachment is attached, a part of the positioning auxiliary member (for example, its tip) is used as an imaging object. By contacting the outside of the imaging range of a business card or the like, the relative positional relationship between the camera-equipped mobile phone and the imaging range can be stabilized. Therefore, if there is a positioning assisting member, it is difficult to cause a problem that the imaging target is out of the imaging range due to camera shake during imaging.
Further, since the positioning auxiliary member is focused on a part of the positioning auxiliary member, it also has a function of enabling easy focusing. Therefore, if there is a positioning assisting member, camera shake can be reduced, so that difficulty in focusing can be reduced.
Furthermore, according to the positioning auxiliary member, the imaging range of the imaging object is determined, so that it is not necessary to adjust the imaging range for each individual imaging.

Such a positioning assisting member is arranged such that the focus position by the camera lens is located at the imageable position of the imaging means when a part of the positioning auxiliary member is brought into contact with the surface on which the imaging object is disposed. The optical distance from the imaging object to the camera lens can be fixed, and the imaging range of the imaging means can be determined so that the imaging range is suitable for an imaging object having one standardized shape. Anything is acceptable as long as it is configured as described above. For example, the shape of the positioning auxiliary member may be a thin plate shape or a rod shape.
The material of this positioning auxiliary member can be made of resin, for example. In this way, the attachment can be made lightweight.

The attachment of the present invention may be configured such that the fixing member and the positioning auxiliary member have a thin plate shape, and can be formed into a substantially card shape when not in use.
If it carries out like this, when not in use, it can be made into a substantially card shape, and it will become compact and easy to carry. Moreover, when the imaging object of the standardized shape is a business card, it can be configured so that it can be put in a business card case together with the business card.
The thin plate-shaped fixing member can be, for example, a thin rectangular plate-like body having a camera hole for exposing the camera lens. By doing so, it is not bulky, so it is easy to carry and can be made compact.
Moreover, the thin plate-shaped positioning auxiliary member can be, for example, a thin rectangular plate-like body. In this way, it is not bulky and can be made compact. In this case, the length in the longitudinal direction of the plate-like body corresponding to the optical distance from the imaging object to the camera lens is set to the focus position and imaging range suitable for the specific standardized imaging object. Can be configured.

The attachment fixing member described above also has a contact surface that contacts the surface on which the camera lens is provided, and the contact surface has a predetermined position at which the camera-equipped cellular phone or digital It is good also as what has an adhesion part for fixing a camera.
In this way, if the adhesive portion is provided at a predetermined position on the contact surface, the camera-equipped mobile phone or the like can be detachably fixed. Therefore, the camera-equipped mobile phone or the like is fixed to both ends in the width direction of the fixing member. There is no need to provide a rib or the like. That is, even if a simple thin plate member is used as the fixing member, the camera-equipped mobile phone or the like can be fixed, and it is not bulky and can be made compact.

Further, the positioning auxiliary member may be connected to the fixing member. In this way, the possibility of losing the positioning auxiliary member can be reduced. Note that the positioning assisting member and the fixing member can be connected by, for example, a hinge or the like.
The fixing member and the positioning auxiliary member may be connected anywhere as long as the fixing member and the positioning auxiliary member can be formed into a substantially card shape or a substantially rod shape when not in use.
For example, you may connect on the back surface side of the contact surface of a fixing member. If it carries out like this, a positioning auxiliary member can be rotated centering | focusing on the connection part with which the fixing member and the positioning auxiliary member are connected, and the predetermined range of a back surface can be moved. In this case, the positioning auxiliary member when not in use can be formed into a substantially card shape or a substantially rod shape by arranging the positioning auxiliary member at a position where the longitudinal direction of the fixing member and the longitudinal direction of the positioning auxiliary member are parallel, and the attachment is used. In this case, the positioning auxiliary member may be rotated around the connecting portion, and may be configured to be used at a position where the longitudinal direction of the fixing member and the longitudinal direction of the positioning auxiliary member are perpendicular to each other. If it carries out like this, it can be made into a substantially card shape or a substantially rod shape at the time of non-use.

Moreover, you may make it the one end of the said positioning auxiliary member be connected with the one end part of the longitudinal direction of the said fixing member.
In this way, the range in which the positioning auxiliary member can be moved can be expanded. That is, the positioning auxiliary member can be rotated to the contact surface side or the back surface side of the fixing member as required, and can be configured to contact the contact surface of the fixing member or the back surface thereof when not in use. it can.

Further, the above positioning auxiliary member may not be connected to the fixing member.
For example, the positioning assisting member can be fitted into the fixing member when not in use, and the shape when fitted is substantially card-like or substantially rod-like, and is fitted into the fixing member when in use. The positioning assisting member may be removed, and the positioning assisting member may be attached (for example, fitted) so that the longitudinal direction of the positioning assisting member is perpendicular to the longitudinal direction of the fixing member.

Moreover, the position of the positioning auxiliary member when the attachment is not used can be configured to be a position that covers the adhesive portion.
By doing so, since the positioning assisting member becomes a cover of the adhesive portion when not in use, it is possible to prevent dirt from adhering to the adhesive portion, and to prevent the adhesive force of the adhesive portion from being lowered.

  The above attachment is an objective lens for adjusting the imaging range imaged by the imaging means to a suitable imaging range, and when this objective lens is attached to the camera lens at a predetermined position, The camera lens exposed from the fixing member may have the same optical axis as that of the camera lens.

If it carries out like this, an imaging range can be adjusted now to a suitable imaging range by attaching an objective lens to an attachment as needed.
As the objective lens of the present invention, a magnifying lens or a reducing lens can be used. If a magnifying lens is used, the imaging range can be adjusted narrowly. On the other hand, if a reduction lens is used, the imaging range can be adjusted widely.
The objective lens may be detachable as necessary, or may be attached in advance to the fixing member and may not be detachable.

In addition, although the above-mentioned positioning auxiliary member may be one, multiple may be sufficient.
For example, a positioning auxiliary member may be connected to one end and the other end in the longitudinal direction of the fixing member.
In this way, the relative positional relationship between the camera-equipped mobile phone and the imaging range can be further stabilized, and camera shake can be further prevented.

  According to the present invention, it is possible to easily determine a focus position and an imaging range when an imaging object having a standardized shape such as a business card is imaged by a mobile phone with a camera or a digital camera. Attachments can be provided.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

Further, the position of the contact portion 20 when not in use is a position that covers the adhesive portion 13. Therefore, when the attachment 1 is not used, the contact portion 20 serves as a cover for the adhesive portion 13, so that it is possible to prevent dirt from adhering to the adhesive portion 13 and to prevent the adhesive force of the adhesive portion 13 from decreasing. can do.
In addition, although the thickest part in the attachment 1 at the time of non-use of this embodiment shall be comprised so that it may be set to 5 mm, it is not restricted to this.

Next, the usage method of this attachment 1 is demonstrated.
This attachment 1 is used by attaching the attachment 1 in a state where the contact portion 20 is disposed at the use position as shown in FIG.
Specifically, as shown in FIG. 3B, the contact portion 20 of the attachment 1 in a card shape is rotated and arranged at the position of FIG. As shown in FIG. 2, the camera-equipped mobile phone 40 in a closed state is pressed against the adhesive portion 13 of the base 10 with the surface on which the camera lens 42 is provided facing downward. At this time, the camera lens 42 of the camera-equipped mobile phone 40 is fixed to a position where it is exposed from the base 10 through the camera hole 11.
Then, as shown in FIG. 4, the camera-equipped mobile phone 40 with the attachment 1 attached is gripped by hand, and the tip of the contact portion 20 is used in contact with the surface on which the business card 100 is placed.
By so doing, imaging can be performed with the tip of the contact portion 20 in contact with the surface on which the business card 100 is placed, so that the problem of camera shake does not easily occur and focus is easily achieved. Moreover, it can be set as the imaging range suitable for the business card 100. As described above, when the contact portion 20 is disposed at the use position, the focus position by the camera lens 42 when the optical distance from the business card 100 to the camera lens 42 is fixed becomes the imageable position. Therefore, if the tip of the abutting portion 20 is brought into contact with the surface on which the business card 100 is disposed, the focus on the business card 100 and thus the imaging range can be automatically determined.
When the camera illumination 44 of the camera-equipped mobile phone 40 is turned on, the business card 100 can be irradiated with light. That is, the amount of light reaching the imaging range can be increased, and the image can be brightened.

In this manner, the business card 100 that is the object to be imaged can be accurately imaged. Depending on the function of the camera-equipped mobile phone used, the data about the image obtained by imaging is recorded in the internal memory of the camera-equipped mobile phone 40 or output from the camera-equipped mobile phone 40 to the outside. Or by using a mail function provided in the camera-equipped mobile phone 40.
When the business card 100 is imaged, the attachment 1 is removed from the camera-equipped mobile phone 40.
And the attachment part 1 can be made into a compact card | curd shape by rotating the contact part 20 and moving to the position which overlaps with the contact surface 10a of the base 10 like FIG.3 (b). .

  Note that when a digital camera is used instead of the camera-equipped mobile phone, it can be used in the same manner as described above.

In the present embodiment, the recess 53 is configured as a hole as described above, but the shape and depth of the recess 53 are not limited thereto. Further, instead of a “hole”, a “hole” penetrating the base 50 may be used.

Further, as shown in FIG. 7, the attachment 2 is used for the semicircular surface 50 b closer to the camera hole 51 out of the two semicircular surfaces located at the longitudinal ends of the base 50. In this case, a recess 54 is provided for connecting the base 50 and a contact portion 60 described later.
The recess 54 has substantially the same shape as the recess 53 described above.

As shown in FIGS. 7 and 8, the contact portion 60 has substantially the same shape as the base 50, that is, a long and thin semi-cylindrical shape.
The contact portion 60 has a rectangular contact surface 60 a corresponding to the contact surface 50 a of the base 50. The contact surface 60 a is provided with a convex portion 61 for connecting the contact portion 60 and the concave portion 53 or the concave portion 54 of the base 50.
The protrusion 61 is a protrusion having a size that can be fitted into the recess 53 or the recess 54.
Further, when the convex portion 61 is fitted into the concave portion 53, as shown in FIG. 9B, the peripheral portion of the contact surface 60a and the peripheral portion of the contact surface 50a overlap each other, and the concave portion 6 and FIG. 9A, the semicircle that is closer to the convex portion 61 among the two semicircular surfaces located at the end in the longitudinal direction of the contact portion 60, as shown in FIGS. The shape surface 60b and the contact surface 50a of the base 50 are located on the same plane, and are provided at positions where the width of the contact surface 60a and the width of the contact surface 50a coincide.

When such an attachment 2 of this embodiment is used, the tip of the contact portion 60 in the state shown in FIG. 9A is brought into contact with the surface on which the business card is arranged.
When the attachment 2 is not in use, the projection 61 of the contact portion 60 is removed from the recess 54 of the base 50 and the projection 61 is fitted into the recess 53 as shown in FIG. In this case, as shown in this figure, the attachment 2 becomes a rod shape when not in use, so that it is compact and easy to carry.
Moreover, since the position of the contact part 60 when not in use is a position that covers the adhesive part 52, the contact part 60 serves as a cover for the adhesive part 52 as in the first embodiment.
In addition, although the thickest part in the attachment 2 at the time of non-use of this embodiment shall be comprised so that it may be 5 mm like 1st Embodiment, it is not restricted to this.

  The usage method of the above attachment 2 is the same as the usage method of the attachment 1 of 1st embodiment.

  Moreover, although the above embodiment demonstrated the case where the imaging target object was a business card, it is not restricted to this, It is also possible to set it as the attachment which has the contact part match | combined with the imaging target object of the other standardized shape. it can.
