  Any method for specifying the position by the position input device 60 may be used. Hereinafter, the position specifying method by the position input device 60 will be described with some examples (A) to (E).

(A) The video 91 projected on the virtual screen 81b by the projector 20 includes a measurement frame 95 as shown in FIG. 6 at a predetermined period. In the measurement frame 95, a plurality of dots are arranged in a grid pattern, and the gradation values (RGB values) of these dots are different from each other. For example, the measurement frame 95 is gradation. The position input device 60 is an interactive pen having a light receiver (color detector) or an electronic camera. The light receiver or the electronic camera performs detection in synchronization with the generation period of the measurement frame 95. When the user touches the position input device 60 with the first reference point 81a of the screen 81 (closes or touches it), the gradation value of the dot overlapped with the first reference point 81a of the screen 81 becomes the light receiver of the position input device 60. Alternatively, it is detected by an electronic camera. In the measurement frame 95, the tone value of the dot varies depending on the position. Therefore, the tone value detected by the light receiver or the electronic camera of the position input device 60 represents the position of the first reference point 81a of the screen 81.

(B) The position input device 60 has a plurality of light projecting elements and light receiving elements arranged along the peripheral edge of the image 91 projected onto the virtual screen 81b, and these light projecting elements extend along the virtual screen 81b. Light (light outside the visible light band is desirable) is emitted, and light emitted from the light projecting elements is received by these light receiving elements. When the user places a finger or an indicator on the first reference point 81a of the screen 81, the light emitted from any of the light projecting elements is blocked by the finger or the indicator or the like, and the position is specified by the light receiving element. That is, a light receiving element that does not receive light is turned off by a finger or an indicator bar, and a light receiving element that receives light is turned on, so that the position of the first reference point 81a of the screen 81 is specified.

(C) The position input device 60 has an electronic camera (for example, an infrared electronic camera) or the like directly facing the screen 81, and a first reference point 81a of the screen 81 (the first reference point 81a has a removable mark). The virtual screen 81b including the first reference point 81a in the captured image is identified by an image processing technique, so that the first screen 81b of the screen 81 can be obtained. The position of one reference point 81a is specified.

(D) The position input device 60 has a plurality of electronic cameras (for example, infrared electronic cameras) arranged around the screen 81, and the first reference point 81a of the screen 81 (the first reference point 81a includes A virtual screen 81b including a mark that can be removed is preferably captured by these electronic cameras, and the position of the first reference point 81a of the screen 81 is determined triangulated from these captured images.

(E) The position input device 60 includes a plurality of ultrasonic detectors and the like arranged along the peripheral edge of the image 91 projected on the virtual screen 81 b, and the user sets the ultrasonic oscillator to the first reference point 81 a of the screen 81. The ultrasonic wave emitted from the ultrasonic oscillator is detected by these ultrasonic detectors, the time until the ultrasonic wave reaches each ultrasonic detector is converted into a distance for each ultrasonic detector, From these distances, the position of the first reference point 81a of the screen 81 is specified trigonometrically.

(F) The position input device 60 is a mouse. The media player 10 or the projector 20 has a GUI (Graphical User Interface) function, a pointer (cursor) is combined with the video by the media player 10 or the projector 20, and the video 91 projected on the virtual screen 81 b by the projector 20 has a pointer. include. When the user operates the position input device 60, the pointer in the video 91 is moved by the GUI function of the media player 10 or the projector 20. When the user puts the pointer on the first reference point 81a of the screen 81 and clicks the click button of the position input device 60, the position of the first reference point 81a of the screen 81 is specified, and a signal indicating the specified position is a medium. The data is transferred from the player 10 or the projector 20 to the control unit 50.

  The position specifying method by the position input device 60 may be a combination of the above (A) to (F). The position specifying method by the position input device 60 is not limited to the above (A) to (F).

  As shown in FIG. 3, the position input by the position input device 60 is transferred to the control unit 50 via the interface 51. The interface 51 receives the signal transferred by the position input device 60 (the signal indicates the position of the first reference point 81a of the screen 81) and transfers the signal to the control unit 50. If the position input device 60 transfers signals wirelessly, the interface 51 includes a wireless receiver (for example, an infrared receiver, a Bluetooth (registered trademark) standard receiver) or the like. If the position input device 60 transfers signals by wire, the interface 51 has, for example, a USB interface. When the position input device 60 does not have a sensor rear-stage circuit (coordinate detection circuit including an AD converter), the interface 51 has a rear-stage circuit, and an output signal of the sensor of the position input device 60 is a rear stage. The output signal is converted into a coordinate signal (the coordinate signal indicates the position of the first reference point 81 a of the screen 81) by performing signal processing by the circuit, whereby the coordinate signal is converted into the position of the first reference point 81 a of the screen 81. Are detected as XY coordinates.

  The control unit 50 is a microcomputer having a CPU and a storage medium (for example, a semiconductor memory). Various functions according to the program stored in the storage medium are realized in the control unit 50, and the horizontal movement device 30 (particularly the motor 35) and the vertical movement device 40 (particularly the motor 44) are integrally controlled by the control unit 50. Is done. The control unit 50 may be a microcomputer (system controller) built in the projector 20 or a computer (system controller) built in the media player 10, or independent of these microcomputers or computers. It may be a computer.

  The motor drive circuit 39 drives the motor 35 according to the control signal input from the control unit 50. The motor drive circuit 49 drives the motor 44 according to the control signal input from the control unit 50.

  In the program stored in the storage medium of the control unit 50, the position of the second reference point 94 (see FIG. 4) of the object 92 in the video 91 is set as the XY coordinates. Here, the second reference point 94 in the object 92 corresponds to the first reference point 81a of the screen 81, and if the second reference point 94 and the first reference point 81a overlap, the entire object 92 becomes the screen 81. The outline of the object 92 overlaps or substantially overlaps the outline of the screen 81. In the program stored in the storage medium of the control unit 50, the distance along the projection optical axis from the projector 20 to the screen 81 and the projection magnification of the projection magnification 20 are set.

  The program stored in the storage medium of the control unit 50 causes the control unit 50 to function as a deviation calculation unit. The control unit 50 functioning as a deviation calculation unit is a vector (an amount of deviation in the X direction and an amount of deviation in the Y direction) from the position of the first reference point 81a to the position of the second reference point 94 input by the position input device 60. ) Is calculated. That is, the control unit 50 functioning as a deviation calculating unit subtracts the X coordinate of the position of the first reference point 81a input by the position input device 60 from the X coordinate of the position of the second reference point 94, and the second reference point. The Y coordinate of the position of the first reference point 81a input by the position input device 60 is subtracted from the Y coordinate of the position of the point 94. In this embodiment, the distance between the projector 20 and the screen 81 is determined in advance, and the amount of deviation in the X direction can be determined from the difference in the X coordinate and the difference in the Y coordinate of the images 94 and 81a by taking into account the magnification of the image 91 and the like. And the amount of deviation in the Y direction can be obtained. Accordingly, the control unit 50 functioning as a deviation calculation unit multiplies the difference between the X coordinates of both 94 and 81a by the projection magnification. The product thus obtained is the amount of deviation in the X direction. The control unit 50 functioning as a deviation calculation unit multiplies the difference between the Y coordinates of both 94 and 81a by the projection magnification. The product thus obtained is the amount of deviation in the Y direction.

  The program stored in the storage medium of the control unit 50 is based on the position of the reference point 81a of the screen 81 and the position of the second reference point 94 of the object 92 input by the position input device 60, The control unit 50 is caused to function as a means for controlling the moving device 40. That is, the program stored in the storage medium of the control unit 50 causes the control unit 50 to function as a horizontal direction movement control unit and causes the control unit 50 to function as a vertical direction movement control unit. The control unit 50 functioning as a lateral direction movement control unit outputs a control signal to the motor drive circuit 39 to rotate the motor 35 by a rotation amount corresponding to the calculated amount of deviation in the X direction. The control unit 50 functioning as a vertical direction movement control unit outputs a control signal to the motor drive circuit 49 to rotate the motor 44 by a rotation amount corresponding to the calculated Y-direction deviation amount.

Then, the usage method of this electronic signboard apparatus 1 and the operation | movement of the electronic signboard apparatus 1 accompanying it are demonstrated.
First, the media player 10, the projector 20, the lateral movement device 30, the vertical movement device 40, the control unit 50, the position input device 60, the reflection mirror 70, the plate model 80, and the like are assembled at the installation site.

  Next, the media player 10, the projector 20, the lateral movement device 30, the vertical movement device 40, the control unit 50, and the position input device 60 are powered on and activated.

  Next, the media player 10 is operated, and the video (moving content) is reproduced by the media player 10. Then, the video signal of the video reproduced by the media player 10 is transferred from the media player 10 to the projector 20. A video 91 according to the video signal is projected by the projector 20.

  When the object 92 in the video 91 does not overlap the screen 81, the position input device 60 is operated and the position of the first reference point 81a of the screen 81 is input by the position input device 60 (input process). Then, the control unit 50 subtracts the X coordinate of the first reference point 81a from the X coordinate of the second reference point 94, and multiplies the difference by the projection magnification to obtain the deviation amount in the X direction. Further, the control unit 50 subtracts the Y coordinate of the first reference point 81a input by the position input device 60 from the Y coordinate of the second reference point 94, and multiplies the difference by the projection magnification to obtain the amount of deviation in the Y direction. Ask.

  Then, the control unit 50 controls the motor drive circuit 39 to rotate the motor 35 by the amount of rotation corresponding to the calculated amount of deviation in the X direction (control process). Thereby, the plate model 80 is moved in the horizontal direction by the amount of deviation in the X direction by the horizontal movement device 30. When the plate model 80 moves by the amount of deviation in the X direction, the control unit 50 stops the motor 35.

  Further, the control unit 50 controls the motor drive circuit 49 to rotate the motor 44 by a rotation amount corresponding to the calculated Y-direction deviation amount (control process). Thereby, the plate model 80 is moved in the vertical direction by the amount of deviation in the Y direction by the vertical movement device 40. When the plate model 80 moves by the amount of deviation in the Y direction, the control unit 50 stops the motor 44.

  When the plate model 80 and the screen 81 are moved by the moving device, the entire object 92 is projected on the screen 81, and the outline of the object 92 overlaps or substantially overlaps the outline of the screen 81 (see FIG. 6).

  Note that the user may turn on the switch connected to the motor drive circuit 39 to operate the motor 35 and thereby move the screen 81 in the lateral direction. Further, the user may turn on the switch connected to the motor drive circuit 49 to operate the motor 44, thereby moving the screen 81 in the vertical direction. The screen 81 can be superimposed on the object 92 by such an operation.

  According to the present embodiment, even if the screen 81 is displaced from the object 92, the screen 81 is moved vertically and horizontally by the moving device simply by inputting the first reference point 81a of the screen 81 by the position input device 60. As a result, the object 92 overlaps the screen 81. Therefore, when the electronic signage apparatus 1 is assembled and installed, the positions of the projector 20, the reflection mirror 70, the screen 81 and the like need not be finely adjusted manually, and the electronic signage apparatus 1 can be easily assembled and installed. Become.

  Further, since the screen 81 is moved by the lateral movement device 30 along the direction of the X coordinate when the position is specified by the position input device 60, the horizontal positioning of the screen 81 is facilitated. Similarly, since the screen 81 is moved by the vertical movement device 40 along the direction of the Y coordinate when the position is specified by the position input device 60, the vertical positioning of the screen 81 is facilitated.

  In the above-described embodiment, the screen 81 is moved vertically and horizontally by the moving devices (the horizontal moving device 30 and the vertical moving device 40) in order to correct the installation position of the screen 81. On the other hand, the screen 81 may be moved by the moving device at another timing / use. For example, when the object 92 in the projection video 91 moves vertically and horizontally, the state where the object 92 overlaps the screen 81 may be maintained by moving the screen 81 by the moving device.
