Description

The present disclosure relates to a mirror stand.

Patent Document 1 discloses an information display device including a display for displaying a reference image and a half mirror that transmits an image displayed on the display and reflects a mirror image of a person's face.

Japanese Unexamined Patent Publication No. 2014-23127

In the information display device described in Patent Document 1, the optical path length until the image of the human face is reflected by the half mirror and reaches the human eyes, and the optical path length until the reference image on the display reaches the human eyes. Is very different. Therefore, it is difficult to focus on both the mirror image (reflection image) and the reference image (superimposed image) at the same time.

Therefore, the present disclosure provides a mirror stand effective for improving the visibility of the reflected image and the superimposed image.

The mirror stand according to one aspect of the present disclosure has a reflecting surface and a transmitting surface opposite to each other, reflects at least a part of the light incident on the reflecting surface, and transmits at least a part of the light incident on the transmitting surface. A half mirror to be used, a monitor that displays a superposed image to be superimposed on the reflected image of the person by the reflecting surface, and a light from the monitor directed to the transmitting surface so that the superposed image passes through the half mirror and faces the person. A relay mirror for reflection and a monitor position adjusting unit for changing the position of the monitor in the direction in which the relay mirror and the monitor are lined up are provided.

In this mirror stand, since the position of the monitor in the direction in which the relay mirror and the monitor are arranged is variable, the imaging position of the superimposed image transmitted through the half mirror can be brought closer to the imaging position of the reflected image of the person. Therefore, it is effective in improving the visibility of the reflected image and the superimposed image.

The mirror stand may further include a focus control unit that controls the monitor position adjustment unit so that the image formation position of the superimposed image transmitted through the half mirror is close to the image formation position of the reflected image. In this case, the position of the monitor is controlled so that the imaging position of the superimposed image is close to the imaging position of the reflected image. Therefore, the visibility of the reflected image and the superimposed image can be further improved.

The mirror stand further includes a distance sensor that detects the distance from the person to the reflecting surface, and the focus control unit determines the optical path length from the monitor to the reflecting surface via the relay mirror and the transmitting surface, and the distance detected by the distance sensor. The monitor position adjustment unit may be controlled so as to be close to. In this case, it is possible to bring the image formation position of the superimposed image closer to the image formation position of the reflected image of the person by the control based on the distance.

The mirror stand may further include a superimposed position control unit that adjusts the display position of the superimposed image in the monitor so that the transmission position of the superimposed image on the reflecting surface and the reflecting position of the reflected image on the reflecting surface are brought close to each other. In this case, the display position of the superimposed image on the monitor is controlled so that the transmission position of the superimposed image and the reflection position of the reflected image come close to each other. Therefore, the visibility of the reflected image and the superimposed image can be further improved.

The mirror stand has a mirror drive unit that changes the direction of the relay mirror and a superposition position that adjusts the direction of the relay mirror by the mirror drive unit so that the transmission position of the superimposed image on the reflection surface is close to the reflection position of the reflection image on the reflection surface. It may further include a control unit. In this case, the transmission position of the superimposed image can be adjusted without being restricted by the image size.

The superimposition position control unit adjusts the orientation of the relay mirror by the mirror drive unit and the display position of the superimposition image in the monitor so that the transmission position of the superimposition image on the reflection surface and the reflection position of the reflection image on the reflection surface are close to each other. You may.

For example, the superimposition position control unit adjusts the display position of the superimposition image in the monitor so that the transmission position of the superimposition image on the reflection surface and the reflection position of the reflection image on the reflection surface are close to each other in the left-right direction, and the superimposition image on the reflection surface. The direction of the relay mirror by the mirror driving unit may be adjusted so that the transmission position of the

According to the method of adjusting the display position of the superimposed image on the monitor (hereinafter referred to as "first method"), the transparent position of the superimposed image can be adjusted by adjusting the image data, thus simplifying the hardware configuration. can do. On the other hand, the adjustment allowance of the display position of the superimposed image on the image data is limited by the image size.

Further, as described above, according to the method of adjusting the orientation of the relay mirror (hereinafter, referred to as “second method”), the transmission position of the superimposed image can be adjusted without being restricted by the image size. On the other hand, in order to adjust the direction of the relay mirror, a mechanism for driving the relay mirror is required.

Here, when the person projected on the reflecting surface is, for example, the face of the user, it is expected that the position of the person in the left-right direction is adjusted to the center of the reflecting surface by the user himself / herself. On the other hand, the height of a person is expected to vary greatly depending on the height of the user. Therefore, by applying the first method to the position adjustment in the left-right direction and the second method to the position adjustment in the up-down direction, the advantages of both methods can be effectively utilized.

The half mirror may be configured such that the reflectance of the light incident on the reflecting surface is higher than the transmittance of the light incident on the transmitting surface. In this case, the visibility of the reflected image and the superimposed image can be further improved.

According to the present disclosure, it is possible to provide a mirror stand that is effective in improving the visibility of the reflected image and the superimposed image.

Hereinafter, embodiments will be described in detail with reference to the drawings. In the description, the same elements or elements having the same function are designated by the same reference numerals, and duplicate description will be omitted.

[Mirror stand]
The mirror stand 1 shown in FIG. 1 has a function of superimposing a monitor image on a reflection image of a person by a mirror. For example, the mirror stand 1 has a function of superimposing a monitor image for a self-care guide on a reflected image of the face of a person who performs self-care such as makeup. As shown in FIG. 1, the mirror stand 1 includes a housing 2, a half mirror 3, a monitor 4, a relay mirror 5, and a monitor position adjusting unit 10. Hereinafter, "up and down" in the description of each element means up and down in a state where the mirror stand 1 is installed for use.

The housing 2 is a case in which the components of the mirror stand 1 are integrated. The housing 2 has an opening 2a on the front surface (the surface facing the user).

The half mirror 3 has a reflecting surface 3a and a transmitting surface 3b that are opposite to each other. The half mirror 3 is fixed to the housing 2 so as to close the opening 2a in a state of being upright (for example, vertically upright) with respect to a horizontal plane, for example. The reflective surface 3a faces the outside of the housing 2, and the transmissive surface 3b faces the inside of the housing 2. The half mirror 3 reflects at least a part of the light incident on the reflecting surface 3a and transmits at least a part of the light incident on the transmitting surface 3b. For example, the half mirror 3 is composed of a base plate such as glass and a reflective film coated on one side of the base plate.

Although the terms "reflecting surface" and "transmitting surface" are used according to the use of the half mirror 3, the properties of both sides are not necessarily different. For example, the half mirror 3 can transmit at least a part of the light incident on the reflecting surface 3a, and can reflect at least a part of the light incident on the transmitting surface 3b.

Further, although the name is given as "half mirror", the reflectance of the half mirror 3 is not necessarily 50%. For example, the half mirror 3 may be configured such that the reflectance of the light incident on the reflecting surface 3a is higher than the transmittance of the light incident on the transmitting surface 3b. The reflectance here is the ratio of the intensity of the reflected light to the intensity of the incident light. Transmittance is the ratio of the intensity of transmitted light to the intensity of incident light. The reflectance of the light incident on the reflecting surface 3a is, for example, 50 to 90%, may be 60 to 80%, or may be 65 to 75%. The transmittance of the light incident on the transmitting surface 3b is, for example, 10 to 50%, may be 20 to 40%, or may be 25 to 35%. These reflectances and transmittances can be adjusted by, for example, the thickness of the reflective film in the half mirror 3.

The monitor 4 displays an image (hereinafter, referred to as “superimposed image”) to be superimposed on the reflected image of the user (person) by the reflecting surface 3a. Specific examples of the monitor 4 include a liquid crystal monitor, an organic EL monitor, and the like. For example, the monitor 4 is arranged in the housing 2 so that the display surface 4a is perpendicular to the transmission surface 3b of the half mirror 3. As an example, the monitor 4 is arranged so that the display surface 4a faces vertically upward. The monitor 4 is positioned so that the height of the display surface 4a is at least lower than the center height of the half mirror 3.

The relay mirror 5 reflects the light from the monitor 4 toward the transmission surface 3b so that the superimposed image passes through the half mirror 3 and faces the user. For example, the relay mirror 5 is arranged in the housing 2 so that its reflection surface 5a faces both the display surface 4a of the monitor 4 and the transmission surface 3b of the half mirror 3. As an example, the relay mirror 5 is arranged above the monitor 4 so that the reflecting surface 5a faces downward and forward (the direction in which the front surface of the housing 2 is located). More specifically, the relay mirror 5 is arranged so that the angle formed by the reflecting surface 5a and the transmitting surface 3b and the angle formed by the reflecting surface 5a and the display surface 4a are both about 45 °.

The monitor position adjusting unit 10 makes the position of the monitor 4 variable in the direction in which the relay mirror 5 and the monitor 4 are lined up. For example, the monitor position adjusting unit 10 is an electric elevating drive unit, and has a motor 11 and a transmission mechanism 12. The motor 11 is a rotary motor that rotates the rotor according to the supply of electric power. The transmission mechanism 12 converts the rotation of the motor 11 into an ascending / descending manner and transmits the rotation to the monitor 4. Specific examples of the mechanism for converting rotation into elevating and lowering include a rack and pinion mechanism, a mechanism using a ball screw, and the like.

The mirror stand 1 may further include a mirror drive unit 20. The mirror drive unit 20 changes the direction of the relay mirror 5. For example, the mirror drive unit 20 is a rotary drive unit that rotates the relay mirror 5 around an axis 23 parallel to both the transmission surface 3b of the half mirror 3 and the display surface 4a of the monitor 4, and connects the motor 21 and the transmission mechanism 22. Have. The motor 21 is a rotary motor that rotates the rotor according to the supply of electric power. The transmission mechanism 22 transmits the rotation of the motor 21 to the relay mirror 5.

The mirror stand 1 may further include a distance sensor 31 and a camera 32. The distance sensor 31 detects the distance from the user to the reflecting surface 3a. Specific examples of the distance sensor 31 include an infrared type or ultrasonic type distance sensor. The distance sensor 31 is arranged above the half mirror 3 in the housing 2, for example. As an example, the distance sensor 31 detects the distance from the arrangement position to the user's face. Based on the detection result by the distance sensor 31, the distance from the reflecting surface 3a to the user's face can be calculated. Therefore, detecting the distance from the arrangement position of the distance sensor 31 to the user's face corresponds to detecting the distance from the reflective surface 3a to the user's face. The distance detected by the distance sensor 31 can be used to control the monitor position adjusting unit 10 so that the imaging position of the superimposed image transmitted through the half mirror 3 approaches the imaging position of the reflected image.

The camera 32 captures the user's face. Specific examples of the camera 32 include a camera having an image sensor such as a CCD (Charged-Coupled Device) and a CMOS (Complementary Metal-Optide-Semiconductor) and an optical system for imaging. The camera 32 is arranged above the half mirror 3 in the housing 2, for example. The image captured by the camera 32 can be used to recognize the reflection position of the reflected image on the reflecting surface 3a. The recognition result of the reflection position can be used to bring the transmission position of the superimposed image on the reflection surface 3a closer to the reflection position.

The mirror stand 1 may further include origin sensors 41, 42, 43. The origin sensor 41 detects whether or not the monitor 4 is at a predetermined origin position. The origin position is such that the image formation position of the superimposed image transmitted through the half mirror 3 is closer to the reflection surface 3a than the image formation position of the reflection image even when the user's face is closest to the reflection surface 3a. It is set. Therefore, when the control for bringing the imaging position of the superimposed image transmitted through the half mirror 3 closer to the imaging position of the reflected image is performed, the monitor 4 moves to a position farther from the relay mirror 5 (for example, than the origin position). It will move to (below the origin position). The imaging position here means an imaging position in the user's eyeball, which is a focus position that the user can visually perceive.

The origin sensors 42 and 43 detect whether or not the relay mirror 5 is at a predetermined origin position. Specific examples of the origin sensors 41, 42, and 43 include a photo sensor such as a photo interrupter. The detection results by the origin sensors 41, 42, 43 can be used to return the monitor 4 and the relay mirror 5 to the origin position.

The mirror stand 1 may further include an operation panel 50 and a controller 100. The operation panel 50 is a panel for inputting operations to the monitor position adjusting unit 10 and the mirror driving unit 20. For example, the operation panel 50 has an on / off switch 51, an ascending switch 52, a descending switch 53, and a determination switch 54 (see FIG. 2). The on / off switch 51 is a switch for switching on / off of the display of the superimposed image. The ascending switch 52 is a switch for instructing ascending the monitor 4 or ascending the superimposed image (increasing the transmission position of the superimposed image on the transparent surface 3b). The lowering switch 53 is a switch for instructing the lowering of the monitor 4 or the lowering of the superimposed image (the lowering of the transmission position of the superimposed image on the transparent surface 3b). The determination switch 54 is a switch that instructs registration of operation input contents. The operation panel 50 is housed in the housing 2 with the on / off switch 51, the ascending switch 52, the descending switch 53, and the determination switch 54 exposed to the outside of the housing 2.

The controller 100 is configured to control the monitor position adjusting unit 10 so that the imaging position of the superimposed image transmitted through the half mirror 3 approaches the imaging position of the reflected image. The controller 100 is configured to further adjust the display position of the superimposed image in the monitor 4 so that the transmission position of the superimposed image on the reflecting surface 3a and the reflecting position of the reflected image on the reflecting surface 3a are brought closer to each other. You may be. The controller 100 is configured to further adjust the direction of the relay mirror 5 by the mirror driving unit 20 so that the transmission position of the superimposed image on the reflection surface 3a and the reflection position of the reflection image on the reflection surface 3a are brought close to each other. It may have been done. For example, the controller 100 controls the monitor position adjusting unit 10 and the mirror driving unit 20 based on the inputs from the distance sensor 31, the camera 32, the origin sensors 41, 42, 43, and the operation panel 50.

FIG. 3 is a block diagram illustrating a configuration functionally equivalent to the controller 100. As shown in FIG. 3, the controller 100 has the origin return processing unit 111, the focus control unit 112, the superimposition position control unit 113, and fine focus adjustment as a functional configuration (hereinafter referred to as “functional block”). It has a unit 114, a focus adjustment value storage unit 115, a height adjustment unit 116, and a mirror angle storage unit 117.

The origin return processing unit 111 controls the monitor position adjusting unit 10 and the mirror drive unit 20 so as to return the monitor 4 and the relay mirror 5 to the origin position based on the detection results of the origin sensors 41, 42, and 43. For example, the origin return processing unit 111 brings the monitor 4 closer to the relay mirror 5 by the monitor position adjusting unit 10 until the origin sensor 41 detects the monitor 4 (for example, the monitor position adjusting unit 10 raises the monitor 4). Further, the origin return processing unit 111 rotates the relay mirror 5 by the mirror drive unit 20 until both the origin sensors 42 and 43 detect the relay mirror 5.

The focus control unit 112 controls the monitor position adjustment unit 10 so that the image formation position of the superimposed image transmitted through the half mirror 3 approaches the image formation position of the reflected image. For example, the focus control unit 112 detects the optical path length (the sum of the distance D2 and the distance D3 in FIG. 1) from the monitor 4 through the relay mirror 5 and the transmission surface 3b to the reflection surface 3a by the distance sensor 31. The monitor position adjusting unit 10 is controlled so as to approach the distance (distance D1 in FIG. 1).

The superimposition position control unit 113 adjusts the display position of the superimposition image in the monitor 4 so that the transmission position of the superimposition image on the reflection surface 3a and the reflection position of the reflection image on the reflection surface 3a are brought close to each other. Specific examples of the superimposed image include an image of a guide 92 for self-care (for example, makeup) of the face 91 (see FIG. 5). For example, the superimposition position control unit 113 changes the image data output to the monitor 4 so as to change the display position of the superimposition image on the monitor 4. Further, the superimposition position control unit 113 recognizes the reflection position of the reflection image on the reflection surface 3a based on the image captured by the camera 32.

The superimposition position control unit 113 directs the direction of the relay mirror 5 by the mirror driving unit 20 and the superimposition image in the monitor 4 so that the transmission position of the superimposition image on the reflection surface 3a and the reflection position of the reflection image on the reflection surface 3a are close to each other. You may adjust the display position of. For example, the superimposition position control unit 113 displays the superimposition image in the monitor 4 so that the transmission position of the superimposition image on the reflection surface 3a and the reflection position of the reflection image on the reflection surface 3a are brought close to each other in the left-right direction (direction orthogonal to the vertical direction). The display position is adjusted, and the direction of the relay mirror 5 by the mirror driving unit 20 is adjusted so that the transmission position of the superimposed image on the reflection surface 3a and the reflection position of the reflection image on the reflection surface 3a are brought closer to each other in the vertical direction.

The superimposed position control unit 113 is configured to adjust both the transmission position in the left-right direction and the transmission position in the vertical direction by adjusting the display position of the superimposed image in the monitor 4. You may. Further, the superimposition position control unit 113 is configured to perform both the adjustment of the transmission position in the left-right direction and the adjustment of the transmission position in the vertical direction by adjusting the direction of the relay mirror 5 by the mirror drive unit 20. You may be. In this case, a drive system having two degrees of freedom is provided: a drive system that rotates the relay mirror 5 around the axis 23 described above, and a drive system that rotates the relay mirror 5 around the axis perpendicular to the display surface 4a of the monitor 4. The mirror drive unit 20 needs to have.

The superimposed position control unit 113 recognizes the size of the reflected image on the reflecting surface 3a based on the image captured by the camera 32, and adjusts the size of the superimposed image on the reflecting surface 3a to the size of the reflected image on the reflecting surface 3a. As described above, the size of the superimposed image in the monitor 4 may be further adjusted.

The focus fine adjustment unit 114 finely adjusts the position of the monitor 4 by the monitor position adjustment unit 10 according to the operation input to the operation panel 50. For example, the focus fine adjustment unit 114 brings the monitor 4 closer to the relay mirror 5 by the monitor position adjustment unit 10 as the ascending switch 52 is turned on (for example, the monitor position adjustment unit 10 raises the monitor 4). Further, the focus fine adjustment unit 114 moves the monitor 4 away from the relay mirror 5 by the monitor position adjustment unit 10 as the lower switch 53 is turned on (for example, the monitor position adjustment unit 10 lowers the monitor 4).

The focus adjustment value storage unit 115 stores the adjustment value of the position of the monitor 4 by the focus fine adjustment unit 114. For example, in the focus adjustment value storage unit 115, the position of the monitor 4 when the focus fine adjustment unit 114 completes the fine adjustment (for example, when the determination switch 54 is pressed) and the focus fine adjustment unit 114 start the fine adjustment. The difference from the position of the monitor 4 at the time point is stored as the adjustment value.

The height adjusting unit 116 adjusts the direction of the relay mirror 5 by the mirror driving unit 20 according to the operation input to the operation panel 50. For example, the height adjusting unit 116 controls the mirror driving unit 20 so as to rotate the relay mirror 5 in the direction of increasing the transmission position of the superimposed image on the reflecting surface 3a as the ascending switch 52 is turned on. Further, the height adjusting unit 116 controls the mirror driving unit 20 so as to rotate the relay mirror 5 in the direction of lowering the transmission position of the superimposed image on the reflecting surface 3a as the lowering switch 53 is turned on. .. When adjusting the orientation of the relay mirror 5 according to the operation input to the operation panel 50, the height adjusting unit 116 monitors the cursor 93 (see FIG. 6) indicating the position of the superimposed image by the superimposed position control unit 113. It may be displayed in.

The mirror angle storage unit 117 stores the adjustment value of the orientation of the relay mirror 5 by the height adjustment unit 116. For example, in the mirror angle storage unit 117, the orientation of the relay mirror 5 (for example, the angle of the reflecting surface 5a) when the height adjusting unit 116 completes the adjustment of the orientation of the relay mirror 5 (for example, when the determination switch 54 is pressed). And the difference from the direction of the relay mirror 5 at the origin position is stored as the adjustment value.

FIG. 4 is a block diagram illustrating a hardware configuration of the controller 100. As shown in FIG. 4, the controller 100 has a circuit 120. The storage 123 is a non-volatile storage medium (eg, flash memory) that can be read by a computer. The storage 123 stores a program for causing the controller 100 to control the monitor position adjusting unit 10 so that the imaging position of the superimposed image transmitted through the half mirror 3 approaches the imaging position of the reflected image. .. The program causes the controller 100 to further adjust the display position of the superimposed image in the monitor 4 so that the transmission position of the superimposed image on the reflecting surface 3a and the reflecting position of the reflected image on the reflecting surface 3a are brought closer to each other. It may be configured in. The program causes the controller 100 to further adjust the direction of the relay mirror 5 by the mirror driving unit 20 so that the transmission position of the superimposed image on the reflection surface 3a and the reflection position of the reflection image on the reflection surface 3a are brought close to each other. It may be configured as follows.

The memory 122 temporarily stores the program loaded from the storage 123, the calculation result by the processor 121, and the like. The processor 121 constitutes each functional block of the controller 100 by executing the above program in cooperation with the memory 122. The input / output port 124 has a monitor 4, a monitor position adjustment unit 10, a mirror drive unit 20, a distance sensor 31, a camera 32, origin sensors 41, 42, 43, and an on / off switch 51 in response to a command from the processor 121. Input / output of an electric signal is performed between the ascending switch 52, the descending switch 53, and the determination switch 54.

The controller 100 is not necessarily limited to the one that constitutes each functional block by a program. For example, the controller 100 may configure at least a part of the functions by a dedicated logic circuit or an ASIC (Application Specific Integrated Circuit) in which the logic circuit is integrated.

The configuration of the mirror stand 1 shown above is just an example. The mirror stand 1 can be changed in any way as long as it includes a half mirror 3, a monitor 4, a relay mirror 5, and a monitor position adjusting unit 10. For example, it is not necessary that the entire area of the half mirror 3 has transparency. Of the half mirrors 3, at least the region A1 corresponding to the display surface 4a of the monitor 4 may have transparency, and the region outside the region A1 may not have transparency.

[Control procedure of mirror stand]
Subsequently, the control procedure of the mirror stand 1 will be illustrated. FIG. 7 is a flowchart illustrating the control procedure of the mirror stand 1. As shown in FIG. 7, the controller 100 executes steps S01, S02, S03, S04, S05, S06, S07, S08, and S09 in this order. In step S01, the controller 100 waits for the on / off switch 51 of the operation panel 50 to be turned on. In step S02, the controller 100 controls the monitor position adjusting unit 10 and the mirror driving unit 20 so as to return the monitor 4 and the relay mirror 5 to the origin position based on the detection results of the origin sensors 41, 42, and 43.

In step S03, the controller 100 causes the mirror drive unit 20 to adjust the direction of the relay mirror 5 according to the operation input to the operation panel 50. In step S04, the controller 100 controls the monitor position adjusting unit 10 so that the imaging position of the superimposed image transmitted through the half mirror 3 approaches the imaging position of the reflected image. In step S05, the controller 100 adjusts the display position so that the transmission position of the superimposed image on the reflecting surface 3a and the reflecting position of the reflected image on the reflecting surface 3a are close to each other, and displays the superimposed image in the monitor 4. In step S06, the controller 100 finely adjusts the position of the monitor 4 by the monitor position adjusting unit 10 according to the operation input to the operation panel 50. The adjustment value of the position of the monitor 4 in step S06 is stored in the focus adjustment value storage unit 115.

In step S07, the controller 100 controls the monitor position adjusting unit 10 so that the imaging position of the superimposed image transmitted through the half mirror 3 approaches the imaging position of the reflected image, as in step S04. At this time, the adjustment value stored in the focus adjustment value storage unit 115 is added to the target position of the monitor 4. In other words, the adjustment result of the position of the monitor 4 by the focus fine adjustment unit 114 is reflected in the control of the monitor position adjustment unit 10 by the focus control unit 112. In step S08, the controller 100 adjusts the display position so that the transmission position of the superimposed image on the reflection surface 3a and the reflection position of the reflection image on the reflection surface 3a are close to each other, and superimposes them on the monitor 4, as in step S05. Display the image. In step S09, the controller 100 confirms whether or not the on / off switch 51 of the operation panel 50 is turned off.

If it is determined in step S09 that the on / off switch 51 is not in the off state, the controller 100 returns the process to step S07. After that, until the on / off switch 51 is turned off, that is, when "NO", the imaging position of the superimposed image transmitted through the half mirror 3 is adjusted, and the transmission position of the superimposed image on the reflecting surface 3a is adjusted. And are repeated.

When the on / off switch 51 is turned off in step S09, that is, when it is determined as "YES", the controller 100 executes step S11. In step S11, the controller 100 ends the display of the superimposed image on the monitor 4. This completes the control procedure for the mirror stand 1.

FIG. 8 is a flowchart showing a procedure for returning the monitor 4 and the relay mirror 5 to the origin position in step S02. First, the controller 100 executes steps S21, S22, S23, S24, and S25. In step S21, the origin return processing unit 111 starts the monitor 4 to rise by the monitor position adjusting unit 10. In step S22, the origin return processing unit 111 waits for the detection of the monitor 4 by the origin sensor 41. In step S23, the origin return processing unit 111 stops the monitor 4 from being raised by the monitor position adjusting unit 10. In step S24, the origin return processing unit 111 starts the rotation of the relay mirror 5 by the mirror drive unit 20. In step S25, the origin return processing unit 111 confirms whether or not the origin sensors 42 and 43 have detected the relay mirror 5.

If it is determined in step S25 that the origin sensors 42 and 43 have not detected the relay mirror 5, the controller 100 executes step S26. In step S26, the origin return processing unit 111 confirms whether or not the rotation angle of the relay mirror 5 by the mirror drive unit 20 has reached a predetermined angle. The rotation angle here is the difference between the current angle of the relay mirror 5 and the angle of the relay mirror 5 in step S24. The predetermined angle is set to a value at which the relay mirror 5 can be reliably rotated to a position detected by the origin sensors 42 and 43 when the rotation direction of the relay mirror 5 is appropriate.

If it is determined in step S26 that the rotation angle of the relay mirror 5 has not reached the predetermined angle, the controller 100 returns the process to step S25. After that, the origin return processing unit 111 continues the rotation of the relay mirror 5 by the mirror drive unit 20 until the origin sensors 42 and 43 detect the relay mirror 5 or the rotation angle of the relay mirror 5 reaches a predetermined angle.

When it is determined in step S26 that the rotation angle of the relay mirror 5 has reached a predetermined angle, the controller 100 executes step S27. In step S27, the origin return processing unit 111 reverses the rotation direction of the relay mirror 5 by the mirror drive unit 20. After that, the controller 100 returns the process to step S25.

If it is determined in step S25 that the origin sensors 42 and 43 have detected the relay mirror 5, the controller 100 executes step S28. In step S28, the origin return processing unit 111 stops the rotation of the relay mirror 5 by the mirror drive unit 20. With the above, the monitor 4 and the relay mirror 5 return to the origin position.

FIG. 9 is a flowchart showing a procedure for adjusting the orientation of the relay mirror 5 in step S03. First, the controller 100 executes steps S31 and S32. In step S31, when the height adjusting unit 116 adjusts the direction of the relay mirror 5, the cursor 93 indicating the display position of the superimposed image is displayed on the monitor 4 by the superimposed position control unit 113. In step S32, the height adjusting unit 116 confirms whether or not the ascending switch 52 is in the ON state.

If it is determined in step S32 that the ascending switch 52 is in the ON state, the controller 100 executes step S33. In step S33, the height adjusting unit 116 rotates the relay mirror 5 in a direction that raises the transmission position of the superimposed image on the reflecting surface 3a at a preset angle of one pitch. Control.

If it is determined in step S32 that the ascending switch 52 is not in the ON state, the controller 100 executes step S34. In step S34, the height adjusting unit 116 confirms whether or not the lowering switch 53 is in the ON state.

If it is determined in step S34 that the down switch 53 is in the ON state, the controller 100 executes step S35. In step S35, the height adjusting unit 116 rotates the mirror driving unit 20 in the direction of lowering the transmission position of the superimposed image on the reflecting surface 3a at a preset angle of one pitch. Control.

Next, the controller 100 executes step S36. If it is determined in step S34 that the down switch 53 is not in the ON state, the controller 100 executes step S36 without executing any of steps S33 and S35. In step S36, the height adjusting unit 116 confirms whether or not the height adjustment end command has been input. For example, the height adjusting unit 116 confirms whether or not the determination switch 54 is turned on.

If it is determined in step S36 that the determination switch 54 is not turned on, the controller 100 returns the process to step S32. After that, until the determination switch 54 is turned on, the direction of the relay mirror 5 is adjusted according to the operation of the ascending switch 52 and the descending switch 53.

If it is determined in step S36 that the determination switch 54 is in the ON state, the controller 100 executes steps S37 and S38. In step S37, the height adjusting unit 116 stores the adjustment value of the orientation of the relay mirror 5 in the mirror angle storage unit 117. For example, the height adjusting unit 116 uses the difference between the direction of the relay mirror 5 at the time when the determination switch 54 is determined to be on and the direction of the relay mirror 5 at the origin position as the adjustment value as the mirror angle storage unit 116. Store at 117. In step S38, the height adjusting unit 116 causes the superimposed position control unit 113 to erase the display of the cursor 93 on the monitor 4. This completes the height adjustment procedure.

FIG. 10 is a flowchart illustrating the procedure for adjusting the imaging position in steps S04 and S07. First, the controller 100 executes steps S41, S42, S43, and S44. In step S41, the focus control unit 112 acquires the detection result of the distance from the arrangement position of the distance sensor 31 to the user's face from the distance sensor 31. In step S42, the focus control unit 112 calculates the distance from the reflecting surface 3a to the user's face based on the detection result acquired in step S41. For example, the focus control unit 112 calculates the distance from the reflection surface 3a to the user's face by multiplying the detection result by the cosine of the inclination angle of the distance sensor 31 with respect to the normal of the reflection surface 3a. In step S43, the focus control unit 112 brings the optical path length from the monitor 4 through the relay mirror 5 and the transmission surface 3b to the reflection surface 3a closer to the distance calculated in step S42 at the target position of the monitor 4 ( Target height) is calculated. In step S44, the focus control unit 112 confirms whether or not the current position of the monitor 4 matches the target position.

If it is determined in step S44 that the current position of the monitor 4 does not match the target position, the controller 100 executes step S45. In step S45, the focus control unit 112 moves the monitor 4 to the target position by the monitor position adjustment unit 10. If it is determined in step S44 that the current position of the monitor 4 matches the target position, the procedure for adjusting the imaging position is completed.

FIG. 11 is a flowchart illustrating the procedure for adjusting the transmission position in steps S05 and S08. The controller 100 executes steps S51, S52, S53, S54, S55, and S56 in this order. In step S51, the superimposition position control unit 113 acquires an captured image of the user's face from the image sensor of the camera 32. In step S52, the superimposition position control unit 113 recognizes the contour of the user's face from the captured image by image processing. In step S53, the superimposition position control unit 113 calculates the reflection position and the size of the reflection image on the reflection surface 3a based on the contour recognized in step S52.

In step S54, the superimposition position control unit 113 calculates the display position of the superimposition image in the monitor 4 so that the transmission position of the superimposition image on the reflection surface 3a approaches the reflection position of the reflection image calculated in step S53. In step S55, the superimposed position control unit 113 calculates the display size of the superimposed image in the monitor 4 so that the size of the superimposed image on the reflecting surface 3a approaches the size of the reflected image calculated in step S53. In step S56, the superimposition position control unit 113 displays a superimposition image (for example, the image of the guide 92 shown in FIG. 5) with the display position calculated in step S54 and the display size calculated in step S55. Image data is generated and output to the monitor 4.

FIG. 12 is a flowchart illustrating a procedure for finely adjusting the height of the monitor 4 in step S06. First, the controller 100 executes step S61. In step S61, the focus fine adjustment unit 114 confirms whether or not the rise switch 52 is in the ON state.

If it is determined in step S61 that the ascending switch 52 is in the ON state, the controller 100 executes step S62. In step S62, the focus fine adjustment unit 114 raises the monitor 4 by the monitor position adjustment unit 10 by a preset amount of increase for one pitch.

If it is determined in step S61 that the ascending switch 52 is not in the ON state, the controller 100 executes step S63. In step S63, the focus fine adjustment unit 114 confirms whether or not the lowering switch 53 is in the ON state.

If it is determined in step S63 that the down switch 53 is in the ON state, the controller 100 executes step S64. In step S64, the focus fine adjustment unit 114 lowers the monitor 4 by the monitor position adjustment unit 10 by a preset lowering amount of one pitch.

Next, the controller 100 executes step S65. If it is determined in step S63 that the down switch 53 is not in the ON state, the controller 100 executes step S65 without executing any of steps S62 and S64. In step S65, the focus fine adjustment unit 114 confirms whether or not the end command for fine adjustment of the height of the monitor 4 has been input. For example, the focus fine adjustment unit 114 confirms whether or not the determination switch 54 is turned on.

If it is determined in step S65 that the determination switch 54 is not in the ON state, the controller 100 returns the process to step S61. After that, until the determination switch 54 is turned on, the height of the monitor 4 is adjusted according to the operation of the ascending switch 52 and the descending switch 53.

If it is determined in step S65 that the determination switch 54 is in the ON state, the controller 100 executes step S66. In step S66, the focus fine adjustment unit 114 stores the height adjustment value of the monitor 4 in the focus adjustment value storage unit 115. For example, the focus fine adjustment unit 114 stores the difference between the height of the monitor 4 at the time when the determination switch 54 is determined to be on and the height of the monitor 4 at the time when step S06 is started as the adjustment value. This completes the procedure for finely adjusting the height of the monitor 4.

A half mirror 3 that transmits at least a part of the light, a monitor 4 that displays a superposed image for superimposing on the reflected image of the person by the reflecting surface 3a, and a monitor so that the superposed image passes through the half mirror 3 and faces the person. It includes a relay mirror 5 that reflects the light from 4 toward the transmitting surface 3b, and a monitor position adjusting unit 10 that changes the position of the monitor 4 in the direction in which the relay mirror 5 and the monitor 4 are arranged.

In the mirror stand 1, since the position of the monitor 4 in the direction in which the relay mirror 5 and the monitor 4 are arranged is variable, the imaging position of the superimposed image transmitted through the half mirror 3 can be brought closer to the imaging position of the reflected image of the person. it can. Therefore, it is effective in improving the visibility of the reflected image and the superimposed image.

The mirror stand 1 may further include a focus control unit 112 that controls the monitor position adjustment unit 10 so that the image formation position of the superimposed image transmitted through the half mirror 3 is close to the image formation position of the reflected image. In this case, the position of the monitor 4 is automatically adjusted so that the imaging position of the superimposed image is close to the imaging position of the reflected image. Therefore, the visibility of the reflected image and the superimposed image can be further improved.

The mirror stand 1 further includes a distance sensor 31 that detects the distance from the person to the reflection surface 3a, and the focus control unit 112 determines the optical path length from the monitor 4 to the reflection surface 3a via the relay mirror 5 and the transmission surface 3b. , The monitor position adjusting unit 10 may be controlled so as to approach the distance detected by the distance sensor 31. In this case, it is possible to bring the imaging position of the superimposed image closer to the imaging position of the reflected image of the person by simple control based on the distance information.

The mirror stand 1 further includes a superimposed position control unit 113 that adjusts the display position of the superimposed image in the monitor 4 so that the transmission position of the superimposed image on the reflecting surface 3a and the reflecting position of the reflected image on the reflecting surface 3a are brought close to each other. You may. In this case, the display position of the superimposed image by the monitor 4 is automatically adjusted so that the transmission position of the superimposed image and the reflection position of the reflected image come close to each other. Therefore, the visibility of the reflected image and the superimposed image can be further improved. Further, since the transmission position of the superimposed image can be adjusted by adjusting the image data, the hardware configuration can be simplified.

The mirror stand 1 has a mirror drive unit 20 that changes the direction of the relay mirror 5, and a relay mirror 5 by the mirror drive unit 20 so that the transmission position of the superimposed image on the reflection surface 3a is close to the reflection position of the reflection image on the reflection surface 3a. A superimposition position control unit 113 for adjusting the orientation of the mirror may be further provided. In this case, the transmission position of the superimposed image can be adjusted without being restricted by the image size.

The superimposition position control unit 113 directs the direction of the relay mirror 5 by the mirror driving unit 20 and the superimposition image in the monitor 4 so that the transmission position of the superimposition image on the reflection surface 3a and the reflection position of the reflection image on the reflection surface 3a are close to each other. You may adjust the display position of.

For example, the superimposition position control unit 113 adjusts the display position of the superimposition image in the monitor 4 so that the transmission position of the superimposition image on the reflection surface 3a and the reflection position of the reflection image on the reflection surface 3a are close to each other in the left-right direction, and is reflected. The direction of the relay mirror 5 by the mirror driving unit 20 may be adjusted so that the transmission position of the superimposed image on the surface 3a and the reflection position of the reflection image on the reflection surface 3a are brought closer to each other in the vertical direction.

As described above, according to the method of adjusting the display position of the superimposed image on the monitor 4 (hereinafter, referred to as "first method"), the transmission position of the superimposed image can be adjusted by adjusting the image data. The hardware configuration can be simplified. On the other hand, the adjustment allowance of the display position of the superimposed image on the image data is limited by the image size.

Further, as described above, according to the method of adjusting the orientation of the relay mirror 5 (hereinafter, referred to as “second method”), the transmission position of the superimposed image can be adjusted without being restricted by the image size. .. On the other hand, in order to adjust the direction of the relay mirror 5, a mechanism for driving the relay mirror 5 is required.

Here, when the person projected on the reflecting surface 3a is the face of the user, it is expected that the position of the person in the left-right direction is adjusted to the center of the reflecting surface 3a by the user himself / herself. On the other hand, the height of a person is expected to vary greatly depending on the height of the user. Therefore, by applying the first method to the position adjustment in the left-right direction and the second method to the position adjustment in the up-down direction, the advantages of both methods can be effectively utilized.

The half mirror 3 may be configured such that the reflectance of the light incident on the reflecting surface 3a is higher than the transmittance of the light incident on the transmitting surface 3b. In this case, the visibility of the reflected image and the superimposed image can be further improved.
