Description

The present invention relates to a reflection photography aid.

Reflection photography is known, in which the image of a subject reflected on the surface of water or other objects is photographed along with the subject. A typical example of reflection photography is an upside-down image of Mt. Fuji. However, if the water surface reflecting the subject, Mt. Fuji, is rippling, it is difficult to obtain a beautiful reflection photograph.

Therefore, when taking reflection photos using, for example, a mobile communication terminal with a camera, a reflection photography aid has been proposed that uses an artificial mirror rather than a natural reflective surface such as the surface of water (see Patent Document 1).

The reflection photography aid described in Patent Document 1 fixes a mirror directly below the camera lens of a mobile communication terminal with a camera, either perpendicular to the back of the terminal or at an angle between 45 and 135 degrees, so that the subject is reflected by the mirror.

Utility Model Registration No. 3232345

However, with conventional reflection photography aids, the mirror is fixed at an angle, such as perpendicular, to the back of the device, making it impossible to adjust the balance between the subject and the image reflected by it. This makes it difficult to take appropriate reflection photographs according to the size, distance, etc. of the subject.

The present invention was made in consideration of the above circumstances, and aims to provide a reflection photography aid that can take appropriate reflection photographs depending on the subject.

In order to solve the above problems, the reflection photography aid in the first invention is:
a photographing device support section for supporting a photographing device for photographing a subject;
a mirror having a reflective surface that reflects the subject;
a mirror support part that supports the mirror at a position in front of the photographing direction of the photographing device supported by the photographing device support part;
Equipped with
At least one of the photographing device support part and the mirror support part is characterized in that it has an adjustment part that adjusts the angle between the optical axis of the photographing device and the reflective surface so as to enable changing the vertical occupancy ratio between the subject and the image of the subject reflected by the reflective surface during reflection photographing.

In the reflection photography aid of the above configuration, the photography device is supported by the photography device support part, and the mirror is supported by the mirror support part, and the subject is photographed while the photography device is photographed without being affected by external factors such as the rippling state of the water surface. In addition, an adjustment part in at least one of the photography device support part and the mirror support part allows adjustment of the angle between the optical axis of the photography device and the reflecting surface. In this case, the user can adjust the angle between the optical axis of the photography device and the reflecting surface according to the size and distance of the subject, thereby changing the vertical occupancy ratio between the subject and the image reflected by the reflecting surface, and optimizing the balance between the subject and the reflected image of the subject in the reflection photograph. As a result, appropriate reflection photography can be performed according to the subject.

In a second invention, at least one of the imaging device support part and the mirror support part has, as the adjustment part, a rotation adjustment part that adjusts the angle between the optical axis of the imaging device and the reflecting surface by rotation. The rotation adjustment part rotates the imaging device so that the side farther from the mirror approaches the mirror, and adjusts the angle so that the optical axis of the imaging device is tilted toward the side closer to the mirror than a position parallel to the reflecting surface.

The inventors have confirmed that the quality of reflection photographs can be improved by tilting the optical axis of the photographing device closer to the mirror than parallel to the mirror's reflective surface. In this regard, with the above configuration, the angle can be appropriately adjusted to obtain the desired reflection photograph by rotating at least one of the photographing device support part and the mirror support part.

In a third invention, the photographing device is a smartphone or tablet with a display screen on the front and a camera lens on the back. The rotation adjustment unit rotates the photographing device support unit so that the side of the photographing device farther from the mirror approaches the mirror, and adjusts the angle so that the optical axis of the photographing device is tilted toward the side closer to the mirror than a position parallel to the reflecting surface, and the photographing device support unit supports the back on both sides that sandwich the camera lens.

In a configuration in which the imaging device support part is rotated so that the side of the imaging device farthest from the mirror approaches the mirror, and the optical axis of the imaging device is tilted closer to the mirror than a position parallel to the mirror's reflecting surface, the imaging device is tilted so that the back side, which is the camera lens side, faces vertically downward, and the back side is supported by the imaging device support part. In this state, the back side of the imaging device is supported by the imaging device support part on both sides of the camera lens. In this case, the area near the camera lens can be held in a stable state, allowing appropriate reflection photography to be performed.

In a fourth invention, a storage container capable of storing the mirror is provided. The mirror support section supports the mirror so that the mirror can slide between a storage state in which the mirror is entirely stored in the storage container and a protruding state in which a portion of the mirror protrudes from the storage container. When the mirror is in the protruding state, the imaging device support section is disposed in the storage container in an area opposite to the protruding side of the mirror where the mirror was disposed in the storage state.

By configuring the reflection photography aid so that the mirror is stored in a storage container, the reflective surface of the mirror can be protected when it is carried or stored. In addition, if the mirror and the photography device can be attached to the storage container together, the photography equipment can be consolidated when photographing reflections, improving the operability of reflection photography. However, if the mirror and the photography device are stored in the storage container, there is a concern that the storage container will become large. In this regard, the mirror is made slidable between a storage state in which the mirror is all stored in the storage container and a protruding state in which a part of the mirror protrudes from the storage container. In addition, when the mirror is in the protruding state, the storage container is arranged so that the photography device support part is located in the area where the mirror was located in the storage state on the opposite side to the side where the mirror protrudes. This makes it possible to compact the reflection photography aid when not in use, while improving the usability of the reflection photography aid when in use.

In a fifth aspect of the invention, the mirror is provided with a protrusion that protrudes from the surface opposite the reflecting surface, and the container is provided with a regulating portion that, in the protruding state, abuts against the protrusion to regulate the amount of protrusion of the mirror.

According to the above configuration, when a part of the mirror protrudes from the storage container, the amount of protrusion of the mirror is restricted by the restricting portion on the storage container side. This makes it possible to prevent the mirror from unintentionally falling out of the storage container when the mirror is in a protruding state.

In the sixth invention, the storage container has a peripheral wall portion that surrounds the mirror in the stored state, and a portion of the storage container on the side where the mirror protrudes in the protruding state in the sliding direction of the mirror is displaceable downward or removable, and the mirror is slid through the opening formed by the displacement or removal.

An opening is formed by displacing or removing a portion of the container in the sliding direction of the mirror, and the mirror is slid through the opening. In this case, the portion of the mirror that protrudes from the container in the sliding direction, i.e., the tip of the mirror that is far from the photographing device, does not have a peripheral wall surrounding the mirror. Therefore, when photographing reflections, the peripheral wall of the container is prevented from appearing in the reflection photo.

In a seventh invention, the photographing device is a smartphone or tablet with a display screen on the front and a camera lens on the back, and includes a container capable of housing the mirror. The photographing device support part is slidably arranged between a state in which the photographing device support part is disposed within the width of the container in a width direction perpendicular to the direction in which the mirror and the photographing device are arranged, and a protruding state in which a part of the photographing device support part protrudes from the container.

In photographing devices such as smartphones, the camera lens may be located at a corner on the back surface of the device. Therefore, if the camera lens is to be located at the center of the mirror's width, there is a concern that part of the photographing device may protrude from the storage container, causing unstable support of the photographing device. In this regard, the photographing device support part is made slidable between a state in which the photographing device support part is located within the width of the storage container in the width direction perpendicular to the direction in which the mirror and the photographing device are lined up, and a protruding state in which part of the photographing device support part protrudes from the storage container. This makes it possible to stably support the photographing device even if the camera lens of the photographing device is located at the center of the mirror's width.

In the eighth invention, the mirror support part is formed by the container, and the container has a pressing part that presses the mirror from the reflecting surface side. The pressing parts are provided at positions on both sides of the reflecting surface in the width direction across the optical axis of the photographing device when the photographing device is supported by the photographing device support part, and the pressing parts on both sides of the reflecting surface in the width direction are shaped so that the opposing parts are spaced apart from each other as they are farther from the photographing device.

By holding down the mirror from the reflective surface side with a holding part in the storage container, it is possible to prevent the mirror from falling off or floating up. However, there is a concern that the holding part located on the reflective surface of the mirror may appear in the reflection photo when photographing the reflection. In this regard, the holding parts on both sides in the width direction are shaped so that the opposing parts are farther apart from each other the further they are from the photographing device, which makes it possible to prevent the holding parts from appearing in the reflection photo.

In a ninth aspect of the invention, the photographing device is a smartphone or tablet with a display screen on the front and a camera lens on the back, and an opening/closing cover that covers the display screen can be attached. The mirror support part includes a cover support part that supports the opening/closing cover of the photographing device supported by the photographing device support part above the mirror.

In photographing devices consisting of mobile terminal devices such as smartphones, an opening/closing cover (such as a notebook-type smartphone case) may be attached to protect the display screen, but there is a concern that the opening/closing cover may get in the way or require removal when photographing reflections. In this regard, by configuring the opening/closing cover of the photographing device supported by the photographing device support part to be supported by a cover support part provided on the mirror support part, it becomes possible to shoot with the opening/closing cover attached to the photographing device when photographing reflections. In addition, by supporting the opening/closing cover above the mirror, the opening/closing cover functions as a visor, making it possible to eliminate excess light when photographing reflections.

The following describes an embodiment of the present invention with reference to the drawings. In this embodiment, a reflection photography aid 10 that aids in reflection photography when using a smartphone, which is a mobile terminal device, is described. Figure 1 shows the configuration of reflection photography aid 10, with Figure 1(a) being a plan view of reflection photography aid 10, Figure 1(b) being a cross-sectional view taken along line A-A in Figure 1(a), and Figure 1(c) being a cross-sectional view taken along line B-B in Figure 1(a).

As shown in FIG. 1, the reflection photography aid 10 has a case 11, a mirror 12, and a smartphone holder 13. FIG. 1 shows a smartphone 20 attached to the smartphone holder 13 in the reflection photography aid 10 as a photography device. With the smartphone 20 attached, the reflection photography aid 10 uses the mirror 12 in front of the camera of the smartphone 20 to photograph the reflection of the subject. The smartphone 20 has two surfaces in the thickness direction, the front surface being a display surface 22 with a display screen (display panel), and the rear surface on the opposite side being a lens surface 23 with a camera lens 21. The smartphone 20 is placed horizontally with its longitudinal direction being the left and right, and is attached to the reflection photography aid 10 with the lens surface 23 facing the mirror 12.

Figure 2 is an exploded perspective view of the case 11 and the mirror 12, and Figure 3 is a vertical cross-sectional view showing the state in which the mirror 12 is assembled into the case 11. In Figure 3, (a) shows the state in which the mirror 12 is entirely housed in the case 11, and (b) shows the state in which part of the mirror 12 is pulled out from the case 11.

Mirror 12 is a flat mirror that is rectangular in plan view. For example, mirror 12 has a short side length of about 100 to 200 mm and a long side length of about 150 to 250 mm. The top surface of mirror 12 in the figure is the mirror reflective surface 12a.

The case 11 is a container in the shape of a flattened rectangular parallelepiped, and is large enough to accommodate the entire mirror 12. A mirror mounting portion 32 on which the mirror 12 is placed is provided on the bottom 31 of the case 11. The mirror mounting portion 32 is, for example, a protruding portion extending in the width direction, which is the direction of the short sides of the case 11, and is provided in two locations parallel to each other. However, the shape of the mirror mounting portion 32 is arbitrary, and it is sufficient that it can support the mirror 12 in a placed state within the case 11.

The two long side peripheral walls 33 of the case 11 that surround the bottom 31 are provided with retaining sections 34 that hold down the mirror 12 from above when the mirror 12 is assembled in the case 11. The mirror 12 is assembled in the case 11 with the mirror reflective surface 12a facing up, placed on the mirror mounting section 32, and held down by the retaining sections 34 from the mirror reflective surface side. A protrusion 12b is attached to the back side of the mirror 12. The case 11 corresponds to a container that houses the mirror 12, and corresponds to a mirror support section that supports the mirror 12.

The case 11 also has a structure that allows the mirror 12 housed inside to be slid and pulled out to the outside. Specifically, the case 11 has a case end 35, which is a part of one end in the long side direction, that can be bent (displaced) downward, and the case 11 is opened to the side by bending the case end 35, and a part of the mirror 12 can be pulled out from the open part to the outside of the case 11. In the structure of FIG. 2, a part of the case 11 that is the protruding tip side of the mirror 12 in the sliding direction of the mirror 12 is the case end 35 that can be displaced downward. For example, a shaft extending in the short side direction of the case 11 may be provided on the bottom 31 of the case 11, and the case end 35 may be rotated by the shaft. Instead of a structure in which the case end 35 is rotated, the case 11 may also be configured so that the case end 35 is removable.

The mirror 12 is slidable with its back side (opposite the mirror reflective surface) placed on the mirror mounting portion 32 and its front side (reflective surface side) held down by the holding portion 34, and a part of the mirror 12 protrudes to the side of the case 11 as the mirror 12 slides. At this time, as the mirror 12 slides, the protrusion 12b on the mirror 12 abuts against the mirror mounting portion 32 on the case 11 side, thereby restricting the amount of sliding movement (protrusion amount) of the mirror 12. In other words, the mirror mounting portion 32 on the case 11 side functions as a restricting portion that restricts the sliding movement of the mirror 12.

In the case 11, when the mirror 12 is supported by the mirror mounting portion 32, the mirror 12 can slide between a contained state in which the mirror 12 is entirely contained within the case 11 and a protruding state in which a portion of the mirror 12 protrudes from the case 11. In the protruding state in which a portion of the mirror 12 protrudes from the case 11, a free space S where the mirror 12 is not present is formed on the side of the case 11 opposite the protruding tip of the mirror 12 (see FIG. 3(b)). The smartphone holder 13, which is a support portion for the photographing device, is then placed in the free space S.

Figure 4 shows the configuration of the smartphone holder 13. Figure 4(a) is a plan view of the smartphone holder 13, Figure 4(b) is a cross-sectional view taken along line C-C of Figure 4(a), and Figure 4(c) is a diagram showing the smartphone 20 attached to the smartphone holder 13.

The smartphone holder 13 has a base portion 41 and a rotation support portion 43 that is rotatably attached to the base portion 41 by a support shaft portion 42. The rotation support portion 43 is a smartphone attachment portion on the smartphone holder 13 where the smartphone 20 is attached. The base portion 41 is plate-shaped and is attached to the case 11 with its lower surface abutting the upper surface of the bottom portion 31. The base portion 41 is attached in an orientation that depends on the case 11, and the rotation support portion 43 is rotatable relative to the base portion 41.

The rotation support part 43 is flat and the angle between it and the base part 41 is adjustable. If the angle between the extension direction of the plate surface of the rotation support part 43 and the extension direction of the plate surface of the base part 41 is θ1, the rotation support part 43 is rotatable within the range of angle θ1 = 0 to 90°. The rotation support part 43 supports the smartphone 20 from the lens surface 23 side in a state where the angle adjustment with respect to the base part 41 is performed. Here, since the base part 41 is provided in an orientation that depends on the case 11 (more specifically, the bottom part 31 of the case 11), the rotation support part 43 makes it possible to adjust the orientation of the smartphone 20 with respect to the case 11 (the bottom part 31 of the case 11). The orientation of the optical axis of the camera lens 21 in the smartphone 20 is adjusted by the rotation of the rotation support part 43. The rotation support part 43 corresponds to a rotation adjustment part.

Of the rotational angle θ1 (0 to 90°) that the rotation support part 43 can rotate, for example, an angle of θ1 = 70 to 90° is the adjustment angle range used when photographing reflections.

The smartphone holder 13 may have a function (angle fixing function) that fixes the rotation support part 43 at an angle when the angle of the rotation support part 43 is adjusted. For example, the smartphone holder 13 may be provided with a fixing member that fixes the position of the rotation support part 43 relative to the base part 41 in the angle adjusted state. Alternatively, the support shaft part 42 of the smartphone holder 13 may be provided with a locking mechanism that locks the rotation position of the rotation support part 43.

Also, the smartphone holder 13 or the case 11 to which the smartphone holder 13 is attached may be marked with a notation indicating the angle of the rotation support part 43, so that the user can adjust the angle while looking at the notation. Also, multiple angles at predetermined angle intervals may be predefined as the adjustment angle of the rotation support part 43, so that the rotation support part 43 can be fixed at each stage.

The smartphone 20 may be supported on both sides in the thickness direction (the lens surface 23 and the display surface 22). For example, as shown in FIG. 4(c), the base portion 41 may be provided with an abutment portion 44 that abuts against the display surface 22 of the smartphone 20.

As shown in FIG. 4(a), the rotation support part 43 has an opening 45 formed by removing a portion of the plate material. This allows the camera lens 21 of the smartphone 20 to be exposed on the mirror 12 side when the smartphone 20 is attached to the rotation support part 43. The size of the opening 45 of the rotation support part 43 is preferably determined taking into consideration that the position of the camera lens 21 differs for each model of smartphone 20. In addition, the rotation support part 43 is preferably provided with a positioning stopper 43a for determining the left-right mounting position of the smartphone 20.

When the smartphone 20 is attached to the pivot support 43, the lens surface 23 of the smartphone 20 is supported on both sides of the width of the camera lens 21 (see FIG. 1(c)).

In addition, in the reflection photography support device 10, it is desirable to place the camera lens 21 of the smartphone 20 in the center position in the width direction of the mirror 12. However, in the smartphone 20, the camera lens 21 may be located at a position biased toward one of the corners of the lens surface 23. Therefore, if an attempt is made to place the camera lens 21 in the reflection photography support device 10 in the center position in the width direction of the mirror 12, there is a concern that part of the smartphone 20 will protrude from the case 11, causing the support of the smartphone 20 to become unstable.

In this embodiment, the smartphone holder 13 is configured to be slidable between a state in which the smartphone holder 13 is disposed within the width of the case 11 and a protruding state in which a portion of the smartphone holder 13 protrudes from the case 11 when the smartphone holder 13 is attached to the case 11. In this case, the smartphone holder 13 is slidable in the width direction of the case 11 (a direction perpendicular to the direction in which the mirror 12 and the smartphone 20 are aligned), and by sliding the smartphone holder 13, it is possible to adjust the position of the camera lens 21 in the width direction of the case 11 with the smartphone 20 supported by the smartphone holder 13. In the case 11, the sliding direction of the smartphone holder 13 is perpendicular to the sliding direction of the mirror 12.

2, the case 11 has an opening 36 in a portion of the peripheral wall 33 to allow the smartphone holder 13 to slide in the width direction of the case 11. The opening 36 is a portion that allows a portion of the smartphone holder 13 to protrude outside the case 11 when the smartphone holder 13 is attached to the case 11. Also, as shown in FIG. 1 and FIG. 4, the base portion 41 of the smartphone holder 13 has a protruding portion 46 that allows the smartphone holder 13 to protrude outside the case 11. The protruding portion 46 is formed by narrowing a portion of one side of the width direction of the case 11 in the base portion 41. When the smartphone holder 13 slides in the width direction of the case 11, the protruding portion 46 of the base portion 41 protrudes outside the case 11. As a result, the smartphone 20 is supported by the smartphone holder 13 in a stable state even when the smartphone 20 is offset in the width direction of the case 11 so that the camera lens 21 of the smartphone 20 is positioned at the center position in the width direction of the case 11.

The opening 36 of the case 11 is provided with a plate-shaped opening/closing section 37 that is part of the peripheral wall section 33, and the opening/closing section 37 allows the opening 36 to be switched between an open state and a closed state.

The reflection photography aid 10 of this embodiment can accommodate the mirror 12 and smartphone holder 13 together in the case 11 when not in use and reflection photography is not being performed with the smartphone 20. Figure 5 is a diagram for explaining the reflection photography aid 10 when not in use.

As shown in FIG. 5(a), when not in use, the mirror 12 is entirely housed within the case 11, and the smartphone holder 13 is placed on top of the mirror 12. At this time, the smartphone holder 13 is placed on top of the mirror 12 with the base part 41 and the rotation support part 43 spread out in a straight line (as shown in FIG. 4(a) and (b)). It is also possible to cover the mirror reflective surface 12a with a protective sheet.

As shown in FIG. 5(b), it is also preferable to attach an upper cover 14 to the case 11. In this case, when the reflection photography aid 10 is not in use or is being carried, the mirror 12 and smartphone holder 13 are stored in a closed container consisting of the case 11 and the upper cover 14.

Next, we will explain the procedure for taking reflection photographs using the reflection photography aid 10.

When taking reflection photographs, in the reflection photography aid 10, the mirror 12 and smartphone holder 13 are stored in a closed container consisting of the case 11 and the top cover 14, and the smartphone holder 13 is removed. Then, with one end of the case 11 open due to bending of the case end 35, the mirror 12 is slid. This transitions the mirror 12 from a stored state in which the mirror 12 is entirely stored within the case 11 to a protruding state in which part of the mirror 12 protrudes from the case 11.

Then, within the case 11, the smartphone holder 13 is placed in the empty space S formed by sliding the mirror 12. The smartphone holder 13 is assembled in the empty space S with the rotation support part 43 folded relative to the base part 41 and the smartphone 20 attached to the rotation support part 43. The smartphone holder 13 is then slid in the width direction of the case 11, so that the camera lens 21 of the smartphone 20 is aligned to a position that is the width center of the mirror 12. It is preferable that a marking or the like is applied to the mirror 12 at a position that is the width center of the mirror 12.

It is preferable that the case 11 is provided with a fixing member to prevent the smartphone holder 13 from shifting out of position or falling off. It is also preferable that the smartphone holder 13 is provided with a fixing member to prevent the smartphone 20 from shifting out of position or falling off.

When photographing the reflection of a subject, the angle between the optical axis of the smartphone 20 and the mirror reflecting surface 12a is adjusted according to the size and distance of the subject. This angle adjustment makes it possible to change the vertical occupancy ratio between the subject and the image of the subject reflected by the mirror reflecting surface 12a during reflection photography, making it possible to take a reflection photo as intended by the user (photographer).

Figure 6 is a schematic diagram showing the state of the reflection photography aid 10 when photographing a reflection. In Figure 6, the angle between the optical axis J of the smartphone 20 and the mirror reflective surface 12a is θ11, and the angle θ11 is adjusted appropriately within a range of, for example, 0 to 20° when photographing a reflection. If the angle between the lens surface 23 of the smartphone 20 and the mirror reflective surface 12a is θ12, the angle θ12 is adjusted within a range of, for example, 70 to 90°.

The rotation support part 43 of the smartphone holder 13 is rotated so that the upper side of the smartphone 20 farthest from the mirror 12 approaches the mirror 12 on the mirror reflective surface side, and the angle of the smartphone 20 is adjusted so that the optical axis J of the smartphone 20 is tilted toward the side closer to the mirror 12 than a position parallel to the mirror reflective surface 12a. This corresponds to the state in FIG. 6 where the angle θ12 is an acute angle (θ12<90°). In this case, the smartphone 20 is tilted so that the lens surface 23 faces vertically downward, and the lens surface 23 side of the smartphone 20 is supported by the rotation support part 43.

In the state shown in FIG. 6, the smartphone 20 is bent forward relative to the mirror 12 with the lens surface 23 facing downward, and the lens surface 23 side is leaning against the rotation support part 43. In this state, the rotation support part 43 supports the lens surface 23 of the smartphone 20 on both sides of the camera lens 21 (see FIG. 1(c)). This allows the smartphone 20 to be held in a stable state near the camera lens.

Figure 1(a) shows the reflection photography aid 10 in a plan view when photographing a reflection. As can be seen from Figure 1(a), the holding parts 34 that hold the mirror 12 in the case 11 have a tapered shape in which the opposing parts move further away from each other the further away from the smartphone 20 they are. This prevents the holding parts 34 from appearing in the reflection photo.

In addition, the case 11 is in a state where the case end 35 is bent downward in order to pull out the mirror 12. Therefore, the peripheral wall portion 33 surrounding the mirror 12 is not present at the portion of the mirror 12 that protrudes from the case 11, i.e., the tip of the mirror that is far from the smartphone 20, and the peripheral wall portion 33 is prevented from appearing in the reflection photograph. In the configuration shown in FIG. 1(a), it is not necessary to make the pressing portion 34 tapered, assuming that the peripheral wall portion 33 other than the case end 35 of the case 11 is not reflected in the reflection photograph. However, since there is a concern about reflection depending on the position of the pressing portion 34, the configuration in which the pressing portion 34 is tapered is effective as one means of preventing reflection.

The user holds the reflection photography aid 10 with the smartphone 20 attached in his/her hand and aims the camera lens 21 of the smartphone 20 at the subject to be photographed. Then, the user performs reflection photography while checking the photographed image displayed on the display screen of the smartphone 20.

Note that in FIG. 1 and other figures, the smartphone 20 is shown mounted horizontally in the smartphone holder 13, with the longitudinal direction being left and right, but the smartphone 20 can also be mounted vertically, with the longitudinal direction being up and down. In other words, the reflection photography aid 10 of this embodiment is capable of supporting the smartphone 20 in both horizontal and vertical orientations.

Figure 7 shows an example of a reflection photograph taken using the reflection photography aid 10. Figure 7(a) is a reflection photograph taken with the reflection photography aid 10 when the angle θ11 between the optical axis J of the smartphone 20 and the mirror reflecting surface 12a is set to 0° (angle θ12 is 90°). Figure 7(b) is a reflection photograph taken with the reflection photography aid 10 when the angle θ11 between the optical axis J of the smartphone 20 and the mirror reflecting surface 12a is set to 5° (angle θ12 is 85°).

In Figures 7(a) and (b), in the reflection photography, a real image of the subject captured directly is designated as X1, and a reflected image by the mirror 12 is designated as X2. Comparing Figures 7(a) and (b), the ratio of reflected image X2 to real image X1 is larger in (b) than in (a), and the reflected image is emphasized.

The configuration of this embodiment described above provides the following excellent effects:

In the reflection photography aid 10 configured as described above, the smartphone 20 is supported by the smartphone holder 13, and the mirror 12 is supported by the mirror mounting portion 32 of the case 11, and the subject is photographed while the smartphone 20 is supported. This allows reflection photography to be performed without being affected by external factors such as the rippling state of the water surface. In addition, the rotation support portion 43 of the smartphone holder 13 allows the angle between the optical axis of the smartphone 20 and the mirror reflecting surface 12a to be adjusted. In this case, the user can adjust the angle between the optical axis of the smartphone 20 and the mirror reflecting surface 12a appropriately according to the size and distance of the subject, thereby changing the vertical occupancy ratio between the subject and the image reflected by the mirror reflecting surface 12a, and optimizing the balance between the subject and the reflected image of the subject in the reflection photograph. As a result, appropriate reflection photography can be performed according to the subject.

In particular, by rotating the pivot support 43, the optical axis of the smartphone 20 is tilted closer to the mirror 12 than a position parallel to the mirror reflective surface 12a. This allows the angle to be adjusted appropriately to obtain the desired reflection photograph.

The smartphone 20 is attached to the pivot support 43 with the rear surface facing the camera lens 21 tilted so that it faces vertically downward, and the pivot support 43 supports the rear surface of the smartphone 20 on both sides of the camera lens 21. In this case, the area around the camera lens can be held in a stable state, allowing appropriate reflection photography to be performed.

The mirror 12 can slide between a stored state in which the mirror 12 is entirely stored in the case 11 and a protruding state in which part of the mirror 12 protrudes from the case 11, and when the mirror 12 is in the protruding state, the smartphone holder 13 is arranged in the area on the opposite side to the side from which the mirror 12 protrudes, where the mirror 12 was arranged in the stored state. This makes it possible to make the reflection photography aid 10 more compact when not in use, while improving the usability of the reflection photography aid 10 when in use.

The mirror 12 has a protrusion 12b on the underside thereof, while the mirror mounting section 32 is provided on the case 11 as a restricting section that restricts the amount of protrusion of the mirror 12 when a part of the mirror 12 protrudes from the case 11. This makes it possible to prevent the mirror 12 from unintentionally falling off the case 11 when the mirror 12 is in a protruding state.

A part of the case 11 in the sliding direction of the mirror 12 is displaced or removed to form an opening, and the mirror 12 is slid through the opening. This prevents the peripheral wall 33 of the case 11 from appearing in the reflection photo.

The smartphone holder 13 is slidable in the width direction of the case 11 between a state in which the smartphone holder 13 is disposed within the width of the case 11 and a protruding state in which a portion of the smartphone holder 13 protrudes from the case 11. This allows the smartphone 20 to be supported in a stable state even if the camera lens 21 of the smartphone 20 is disposed in the center position in the width direction of the mirror 12.

In the case 11, the mirror 12 is held down from the reflective surface side by the holding parts 34, which prevents the mirror 12 from falling off or floating up. In addition, the holding parts 34 on both sides in the width direction are shaped so that the opposing parts are spaced apart as they move away from each other on the side farther from the smartphone 20, which prevents the holding parts 34 from appearing in the reflection photo.

The present invention is not limited to the above embodiment, and may be implemented, for example, as follows.

- As shown in FIG. 8, in the reflection photography aid 10, the mirror 12 housed in the case 11 may be rotatable. In this case, instead of the above-mentioned configuration in which the smartphone holder 13 side rotates, the angle between the optical axis of the smartphone 20 and the mirror reflective surface 12a can be adjusted by rotating the mirror 12. Note that in the reflection photography aid 10, both the smartphone 20 side and the mirror 12 side may be rotatable.

Specifically, mirror mounting sections 32A and 32B are provided on the bottom 31 of the case 11, and the mirror 12 is sandwiched between the pressing section 34 and the mirror mounting section 32A closer to the smartphone 20, and the height position of the mirror 12 from the bottom 31 of the case 11 can be adjusted by a height adjustment member 51 on the mirror mounting section 32B farther from the smartphone 20. The height adjustment member 51 is, for example, a male screw member. In this case, by adjusting the height of the height adjustment member 51, the mirror 12 rotates, and the angle between the optical axis of the smartphone 20 and the mirror reflective surface is adjusted.

- In the smartphone 20, the position of the camera lens 21 on the lens surface 23 differs for each model, and when the smartphone 20 is attached to the reflection photography support device 10, the relative position in the height direction between the camera lens 21 and the mirror reflection surface 12a may vary. As a countermeasure, a configuration that allows the mounting position of the smartphone 20 in the height direction relative to the mirror reflection surface 12a to be adjusted may be adopted. For example, as shown in FIG. 9, a height adjustment plate 61 is interposed as a height adjustment part between the bottom 31 of the case 11 and the smartphone holder 13. In this case, by changing the number of stacked height adjustment plates 61, it is possible to adjust the height position of the camera lens 21 relative to the mirror reflection surface 12a. Note that the configuration of the height adjustment part can be changed, and for example, a height adjustment mechanism for the smartphone 20 may be provided on the base part 41 or the rotation support part 43 of the smartphone holder 13.

As described above, by making it possible to adjust the mounting position of the smartphone 20 in the height direction relative to the mirror reflecting surface 12a, the variation in the relative positions in the height direction between the camera lens 21 and the mirror reflecting surface 12a is suppressed even if different models of smartphones 20 are used, and thus the quality of the reflection photograph can be improved.

- The smartphone 20 is often used with a smartphone case attached. There are also known so-called notebook-type smartphone cases that have an opening and closing cover that covers the display screen of the smartphone 20. In this case, the opening and closing cover of the smartphone case gets in the way when taking reflection photographs using the reflection photography aid 10, but it is troublesome to remove the smartphone case every time you take a reflection photograph. As a countermeasure to this, it is recommended to configure the reflection photography aid 10 as shown in FIG. 10.

10, the smartphone 20 with the smartphone case 70 attached is attached to the reflection photography aid 10. As is well known, the smartphone case 70 has a back cover 71 fixed to the lens surface 23 side (back side) of the smartphone 20, and an opening/closing cover 72 covering the display surface 22 side of the smartphone 20. The case 11 is provided with a cover support member 80 for supporting the opening/closing cover 72 on the outside of the peripheral wall portion 33 on the long side. The cover support member 80 has a vertical arm 81 extending upward from the case 11 and a horizontal arm 82 extending from the upper end of the vertical arm 81 toward the center of the mirror in the case width direction, and the lower end of the vertical arm 81 is supported by the shaft portion 83 so as to be rotatable relative to the peripheral wall portion 33. Note that in FIG. 10, the horizontal arm 82 is shown extending in a direction along the paper surface, but in reality it is configured to extend in a direction perpendicular to the paper surface. The cover support member 80 is preferably configured to be stored on the case 11 side by rotating the shaft portion 83.

The opening/closing cover 72 of the smartphone case 70 is supported on the back side of the smartphone 20, i.e., above the mirror 12, with the display screen side of the smartphone 20 open. This makes it possible to shoot reflection photography with the smartphone case 70 attached to the smartphone 20. In addition, by supporting the opening/closing cover 72 above the mirror 12, the opening/closing cover 72 functions as a visor, eliminating excess light when shooting reflection photography.

- In the above embodiment, a configuration in which a smartphone 20 is attached to the reflection photography aid 10 as a photography device has been described, but instead of the smartphone 20, a configuration in which a tablet with a camera, which is a mobile terminal device, is attached may also be used. When attaching a tablet, the vertical, horizontal, and thickness dimensions of the housing are likely to be larger than those of the smartphone 20, and the size of the photography device support part in the reflection photography aid 10 may be changed to match this dimensional expansion.

- In the above embodiment, the reflection photography aid 10 is configured so that the smartphone holder 13 can be separated from the case 11, and is set in a predetermined position to the side of the mirror when in use (open area S in FIG. 3(b)). However, this configuration may be changed. For example, the smartphone holder 13 may remain attached to the case 11 in a predetermined position to the side of the mirror in both the used and unused states, and the rotation support part 43 may be rotated in this state to adjust the angle.

- In the above embodiment, the reflection photography aid 10 is described as having a mirror 12 and a smartphone holder 13 integrally provided in the case 11, but this configuration may be changed. It may be configured without using the case 11 as a storage container, and in short, the reflection photography aid may be provided with an adjustment unit that adjusts the angle between the optical axis of the photography device and the reflective surface of the mirror. A single-lens reflex camera or a mirrorless single-lens camera may be used as the photography device. In such a case, the photography device may have a photography device support unit that supports the photography device and a mirror support unit that supports the mirror at a position forward of the photography device in the photography direction, and at least one of the photography device support unit and the mirror support unit may have an adjustment unit that adjusts the angle between the optical axis of the photography device and the reflective surface.
