  Hereinafter, an embodiment of an imaging device according to the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a configuration of a digital platform apparatus according to the first embodiment of the present invention.

  In FIG. 1, a table type screen device 10 includes a display device unit 11, a control unit 20 composed of a microcontroller, and a display control unit 21 as control means for controlling the overall control operation of the table type screen device 10. The position detection unit 23 is a position detection unit, the operation determination unit 24 is an operation determination unit, the communication unit 25 is an interface unit, the recording unit 26, and the printer 27. The display device unit 12 projects an image, and includes a projector 13 as a projection unit (reception device, reception unit), a mirror 14 for guiding a projection image to a screen 155, a screen 15 as a display unit, and a surface. It is comprised from the touchscreen 16 comprised as a sensor part (plane part).

  The screen 15 is actually composed of a transparent base portion having a predetermined thickness and a diffusion screen portion so that the table does not bend when a force is applied on the screen. Since it has a predetermined strength as described above, even if the touch panel 16 is pressed or a force such as a camera 31 or the like is placed and pressed as will be described later, the screen 15 does not bend or break. I have to.

  The touch panel 16 is a touch switch for detecting movement of a device or a user's finger on the screen 15. As the touch panel 16, a touch panel whose electrical characteristics are changed by a pressing force on the panel is used.

  The display control unit 21 controls an image projected by the projector 13. The position detection unit 23 detects a position on the screen 15 on which the camera 31 is placed as described later, and the operation determination unit 24 detects and determines a position where the touch panel 16 is pressed. . The communication unit 25 performs data communication with the camera 31 placed on the screen 15 and receives image data compressed and stored by an image processing circuit in the camera.

  The recording unit 26 is for recording an image captured from the camera 31 via the communication unit 25, and constitutes a recording unit for an album, for example. The printer 27 is for outputting the acquired image on paper or the like.

  In such a configuration, the user 30 places the camera 31 that has been photographed and has image data as the transmission device on the table-like screen 15. Then, the touch panel 16 reacts to detect the position of the camera 31. Then, the communication unit 25 of the table-like screen starts communication with the communication unit of the camera 31, and the photographing data can be displayed on the display device unit 11 by the control unit 20.

  That is, in the display device unit 11, the image is projected by the projector 13 via the display control unit 21 by the control unit 20 and displayed on the screen 15 reflected by the mirror 14. Here, the image projected by the projector 13 is not an image acquired from the camera 31 but an image including the image of the camera 31. In addition, the image projected from the projector 13 is laid out so as to be visible in the vicinity of the camera 31, as shown in FIG.

  The touch panel 16 on the screen 15 can also detect the position of the camera 31, and an image corresponding to the image data acquired from the camera 31 is controlled to be displayed near the camera 31. In this case, as shown in FIG. 2, an album storage recording area 26a is provided at a predetermined position. When the user 30 drags an arbitrary image 33 on the screen 15 with a finger and brings it to the position of the recording area 26a, the image can be recorded in the recording section 26 for album. At this time, the image 33 is moved from the camera 31 to the recording area 26a so as to flow. For example, when a plurality of images are moved, the images are sequentially moved from the camera 33 toward the recording area 26a like a slide display. Such an application is also possible.

  In order to realize such a drag function, the screen 15 includes an operation determination unit 24 that detects and determines the position where the touch panel is pressed in order to detect the position of the user's finger. When the operation determination unit 24 determines that the touch panel 16 is pressed, the control unit 20 displays the display control unit as if the image 33 is dragged on the screen 15 based on the determination result. 21 is controlled to switch the display.

  When the image 33 is stored in the album, control is performed so that image data corresponding to the image 33 can be recorded in the recording unit 26. That is, the control unit 20 detects the position of the camera 31 and the operation input by the user 30 by the touch panel 16, the position detection unit 23, and the operation determination unit 24. Then, the image data input by the communication unit 25 is captured according to the position of the device such as the camera 31 described above and the operation described above, and the display control unit 21 is controlled so as to correspond to the position according to the operation described above. Is displayed.

  FIG. 3 is a flowchart for explaining the operation according to the program controlled by the control unit 20.

  When a power switch (not shown) of the table type screen device 10 is turned on, it is determined whether or not the camera 30 is placed on the screen 15 in step S1. When the user 30 places the camera 31 on the table-like screen 15, it is detected that the camera is placed from the change in the pressing force at that time. Then, according to the pressed position of the touch panel 16, the camera position is detected by the position detector 23 in step S2.

  Next, in step S3, data in the camera 31 is read by the communication unit 25. In step S4, the display control unit 21 is controlled so that an image corresponding to the data read at that time is projected to be reproduced near the camera position detected in step S2.

  Thereafter, in step S5, it is determined whether or not the user 30 has operated. Here, if no particular operation is performed, this routine ends. On the other hand, if any operation is performed, the process proceeds to step S6, and each processing operation is performed.

  That is, the pressed state of the touch panel 16 and the change in the pressed position are determined. For example, in step S6, a double click (double tap) of a predetermined image is determined. Here, when the double click is not performed, the process proceeds to step S10 described later, and when the double click is performed, the process proceeds to step S7 to determine whether the image is a pre-enlargement image.

  Here, in the case of the pre-enlargement image, the process proceeds to step S9 and an enlarged display is performed. On the other hand, when it is determined that the image is not the pre-enlargement image, that is, the post-enlargement image, the process proceeds to step S8 and the reduced display is performed. In this way, in step S8 or S9, the user 30 is devised so that it can be handled in a desired size, such as checking and appreciation by image enlargement, and arrangement by image reduction. This is performed by the control unit 20 controlling the display control unit 21. The ratio of the predetermined image described above may be increased in the entire screen.

  In step S10, it is determined whether the finger is traced on the table-like screen 15 and is shifted from a predetermined image position to another position, that is, the operation position is moved. Here, if it does not move, it will transfer to step S12 mentioned later, and if it moves, it will transfer to step S11.

  In step S11, the display position is switched so that the image is moved to the different position. If the destination is an album part as shown in FIG. 2 as the recording area 26a, the destination is determined in step S12. If the destination is the recording area 26a, the process proceeds to step S13, and image data is recorded in the recording area 26a.

  FIG. 4 shows an example of an album created in this way. Here, an example of a display form of an electronic album created in the recording unit 26 of the table type screen device is shown.

  In this way, the moved image is displayed like a simple album 26b placed on the table, and can be displayed completely different from a paper album. In this case, when the user 30 touches the triangular switch section 16a or 16b, the page can be returned and the album 26b can be viewed. The display position of the album 26b can also be switched to an arbitrary position on the table by a drag operation.

  When the print (PRINT) button 16c is pressed, an image recorded on the paper is printed out from the print output discharge port 27a (see FIG. 2).

  When the recording destination is not the recording area 26a in step S12 and after the recording is completed in step S13, the process proceeds to step S5 and the subsequent processing operations are repeated.

  As a communication method of the communication unit 25, optical communication is also conceivable, but it is preferable that there is no directivity. Therefore, it is preferable to perform communication using weak radio waves such as Bluetooth (registered trademark).

  Furthermore, the touch panel 16 may be configured as shown in FIG. 5, for example.

That is, a plurality of switches composed of transparent electrodes such as P _{1 to} P ₁₂ may be provided on the screen 15 to determine which switch is pressed and turned on. That is, the switch control unit 41 sequentially turns on / off the switches in the switch units 42a and 42b in time series, and whether or not the current is supplied at this time is determined by the detection unit 43b based on the output result of the ammeter 43a. If the determination is detected, it is possible to determine which switch (which location) is being pressed.

For example, when a finger or a device is placed at the position of the switch P ₁ and the switch is turned on, when the switch S1 of the switch unit 42a and the switch SA of the switch unit 42b are turned on, the current is output from the ammeter 43a. Detected.

Here, the simplification is made with _twelve switches P _{1 to} P ₁₂ , but in reality, it is assumed that an infinite number of such switches are laid.

  Further, the display device unit 11 described above may be configured as shown in FIG.

  That is, in the display unit 11 ′, a panel 16 ′ whose reflection changes when pressed by a finger is disposed on the screen 15, and a mirror for guiding the light of the projector 13 to the screen 15 is a half mirror 14a or It consists of a mirror with wavelength conductivity. Thereby, the change in shadow due to the change in reflection is detected by the image sensor 46 via the light receiving lens 45, and the position of the finger is detected.

  Of course, the display device unit 11 according to the first embodiment described above may be configured by combining both the touch panel shown in FIG. 5 and the display device unit 11 ′ shown in FIG.

  By using such a touch panel screen, the position of the device or the finger can be determined. Whether the device is a device or a finger is determined according to the size and shape of the range of the pressed portion or the communication result of the communication unit 25 described above.

  That is, in the example of the touch panel shown in FIG. 5, the number of switches being pressed is small for a finger, and there is a change with time such as when dragging. On the other hand, when the camera 31 is placed, the number of pressed switches is large, there is no change with time, and predetermined communication with the communication unit 25 is established.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.

  In the first embodiment described above, an example in which one device (camera) is placed on the screen has been described. However, in the second embodiment, a plurality of devices are placed on the screen. An example of the case will be described.

  FIG. 7 is a diagram illustrating a configuration of a digital platform apparatus according to the second embodiment of the present invention.

  In the embodiment described below, the configuration and basic operation of the digital platform device are the same as those in the first embodiment shown in FIGS. The same parts are denoted by the same reference numerals, illustration and description thereof are omitted, and only different configurations and operations will be described.

  For example, consider a case where a camera 31 in which captured image data is recorded and a printer 35 are placed on the screen 15. Then, in order to obtain a correct image print from the printer 35, an image in the camera 31 as a transmission device is displayed on the screen 15 (image 33) as shown in FIG. Of these, only the selected one (33a) displays the data exchange in a format that enters the printer 35 as a receiving device, so an image different from the photograph that the user had mistakenly thought is printed. Can be prevented.

  In order to realize such an embodiment, in the second embodiment, the camera 31 and the printer 35 communicate with the communication unit 25 of the table type screen 15 wirelessly, and the communication unit 25, the control unit 20, The device type determination unit 24a for determining the type of device is provided between the two.

  This can be easily realized by allowing each device to transmit a signal indicating its function and allowing the position detector 23 to detect the position of each device.

  For example, when the camera 31 is placed at a position as shown in FIG. 7, the image 33 is displayed in the vicinity thereof. If the user drags one of the images 33, the image is displayed in such a manner that the location is moved as in the image 33a according to the movement of the finger. If the display control unit 21 determines that the moving location has come close to the printer 35, the user determines that the printer 35 wants to print the image. The control unit 20 transmits image data to the printer 35 via the display control unit 21, and the printer 35 prints out an image corresponding to the transmitted data.

  In FIG. 7, only the image 33 a is shown, but it is needless to say that an image obtained from the camera 31 can also be displayed near the printer 35.

  As described above, in order to print out the photographic image selected by the user without fail, the control unit 20 must always know which image data is displayed at which position.

  FIG. 8 is a flowchart illustrating an image data display operation performed by the digital platform device according to the second embodiment. Hereinafter, a method of grasping the image display position will be described with reference to this flowchart.

First, in step S21, the subroutine “camera position detection P _C ” is executed, and then in step S22, the subroutine “printer position detection P _P ” is executed. Details of these subroutines of steps S21 and S22 will be described later.

Next, in step S23, the image data read from the camera 31 is reproduced at the screen positions P _{1 to} P ₃ in front L of the detected position P _C of the camera 31, as shown in FIG. , Three images 33 are arranged. Furthermore, in the subsequent step S24, the position P ₄ to P ₆ in the front of the distance L, another captured image is displayed. The distance L is equivalent to the vertical size of the image.

  As described above, the control unit 20 first determines the display position in consideration of the camera position.

  Next, in step S25, it is determined whether or not there is a press on the display position. Here, if the above-mentioned pressing substantially corresponds to the size or shape of the tip of the finger, it is determined that the finger is pressed at the display position, and the process proceeds to step S26. This pressed portion is monitored sequentially, and it is determined in step S26 whether or not it has moved.

If there is no movement of the image in step S26 or if there is no press in step S25, the process proceeds to step S25. On the other hand, if it is determined in step S25 that there is a press and it is determined in step S26 that the image has moved, the process proceeds to step S27, and the image displayed in that portion is also moved in accordance with the movement. Then, at the subsequent step S28, one of the image each time the movement is displayed in staggered position P ₇ either are associated.

This association results in step S29, the printer position P _P detected at that position and the step S21 whether or not within a predetermined distance range is determined. If the distance is not within the predetermined distance range, the process proceeds to step S25. On the other hand, if there is a printer location P _P is within the predetermined distance, the process proceeds to step S30.

  In step S30, a display position shift is performed in order to express an image in which the image 33a is sucked into the printer 35. In step S31, digital image data corresponding to the display image is input to the printer 35. In step S32, a command to print out the image input to the printer 35 is transmitted. As a result, the printer 35 prints the transmitted image data as an image.

  In this way, the user can select a favorite image of the captured image data in the camera as if there is a photograph, and can reliably print out the image from the printer.

  Next, with reference to FIG. 9, a method of detecting each device in the digital platform apparatus according to the second embodiment will be described.

When the camera 31 of Δx _c × Δy _c having a square bottom surface is placed on the touch panel screen 15 of the table type screen device 10, the touch panel is pushed within the range (Δx _c × Δy _c ). For example, in the case of the switch having the configuration shown in FIG. 5, since the switch is turned on based on the bottom surface, the position of the camera can be detected from the range of the turned on switch according to the flowchart of FIG.

FIG. 10 is a flowchart for explaining the operation of the subroutine “camera position detection P _C ” in step S21 of the flowchart of FIG.

When this subroutine is entered, first, in step S41, a portion that is turned on in the range of Δx _c × Δy _c among the turned-on switches P _{1 to} P ₁₂ is detected. In step S42, it is determined whether or not there is a portion that is turned on within the above range. If there is no portion that is turned on, the process proceeds to step S41. On the other hand, if there is a part that is turned on, the process proceeds to step S43.

In this step S43, the center-of-gravity position coordinates x _c and y _c in the turned-on switch range are set as the camera position P _C. However, since there is a possibility that what is placed in this switch range is a box other than the camera, it is confirmed in the subsequent step S44 whether or not the communication unit 25 has made an appropriate handshake with the camera 31. The

If it is determined that the camera is not used, the process proceeds to step S41. On the other hand, if it is determined that the camera, the camera position P _C is determined, the process proceeds to step S45. Then, this subroutine is exited.

The printer 35, for example as shown in FIG. 9, four places on its bottom surface, is provided with leg portions 35a, its width and depth [Delta] x _p, if [Delta] y _p, panel that satisfies the respective matter The printer position is determined based on whether or not there is a pressing portion.

FIG. 11 is a flowchart for explaining the operation of the subroutine “printer position detection P _P ” in step S22 of the flowchart of FIG.

  When this subroutine is entered, first, at step S51, it is determined whether or not there are pressing conditions for the four legs 35a. Here, if there are four pressing portions, it is determined in the subsequent step S52 whether or not the distance of the leg portion 35a satisfies a predetermined condition. Here, when there are no four pressing portions in step S51, or when the distance of the leg portion 35a does not satisfy the predetermined condition in step S52, the process proceeds to step S51.

On the other hand, if there are four pressing portions and the distance between the leg portions 35a satisfies the predetermined condition in steps S51 and S52, the process proceeds to step S53. In this step S53, the coordinates x _p and y _p of the center of gravity of the quadrangle having the four legs 35a as the four corners are detected, and the position is set as the position of the printer.

However, as in step S44 of the flowchart of FIG. 10, there is a case where the one placed at the center of gravity is not a printer, so in step S54, it is determined whether or not communication with the printer is possible. As a result, if communication is possible, it is determined that the printer is correct, the process proceeds to step S55, and the printer position _PP is determined. On the other hand, if it is determined in step S54 that the printer is not a printer, the process proceeds to step S51.

  Although a camera and a printer have been described as examples here, the same method is used when inputting an image from a camera to a storage, which is a large-capacity recording unit, or when projecting and displaying camera data with a projector or the like. Data can be reliably exchanged using position detection and communication.

  For example, as shown in FIG. 12, an image stored in the storage 50 that is a transmission device is displayed on a screen by a projector 51 that is a reception device, and an image 52 may be appropriately magnified by the projector 51. it can. In this case, for example, the image 33 displayed on the screen may be in the vicinity of the storage 50 and in the vicinity of the project 51. Alternatively, it may be displayed near both the storage 50 and the project 51.

  Further, in the camera position detection and the printer position detection shown in FIGS. 9 to 11, the touch panel function is used, but the following examples are also conceivable in order to distinguish individual devices on the screen.

  That is, as shown in FIG. 13A, a two-dimensional barcode 31a may be provided on the lower surface of the camera 31 or the like. Further, as shown in FIG. 13B, an IC tag 31 b may be provided on the lower surface portion of the camera 31. Further, as shown in FIG. 13C, an infrared communication device 31 c may be provided on the lower surface portion of the camera 31.

  As described above, various application modifications can be considered.

  FIG. 14 is a diagram showing a configuration example of a camera position detection system in a digital platform device of a type that reads a barcode 31a as shown in FIG. 13 (a), for example.

  Here, the screen 15a is constituted by an LCD, and the LCD control circuit 15b is configured to be able to electrically switch the transmissive or light diffusion type screen 15a. That is, when reading the barcode on the lower surface of the camera 31, the LCD 15 a is transmitted, and the light from the projector 13 is irradiated to the barcode 31 a by the half mirror 14. The reflected light is detected by the light receiving lens 45 and the monitor image sensor (sensor) 46.

  FIG. 15 is a flowchart for explaining an operation of barcode detection by the camera position detection system having such a configuration.

  When entering this routine, first, the LCD 15a is made transparent in step S61. In step S62, when uniform light is projected from the projector 13, the light is reflected by the half mirror 14a and guided to the barcode 31a disposed on the lower surface of the camera 31.

  In step S 63, the light reflected by the barcode 31 a passes through the half mirror 14 a and is read by the image sensor 46 through the light receiving lens 45. Thereby, the position of the camera 31 is detected. Here, in step S64, communication with the camera 31 is performed by the communication unit (see FIG. 1).

  Next, in step S65, the LCD 15a is switched to the light diffusion mode by the LCD control circuit 15b so that the output image of the projector 13 can be displayed. Thereafter, in step S66, the image in the camera 31 is projected from the projector 13 to reproduce and display in the vicinity of the camera 31.

  As described above, according to the second embodiment, device information and its position can be determined more accurately by code detection that detects a device other than the communication means using radio waves for image data.

  In the first and second embodiments described above, the example is described in which the device is placed on the table with the display function. However, the present invention is not limited to this.

  For example, as shown in FIG. 16, the flat panel display 10a is placed on a general table 10b. In this state, when the camera 31 or the printer 35 is placed on the table 10b, each device is determined by the communication units 25a and 25b. Then, the image data recorded in the internal memory of the camera 31 is displayed as an image 33 on the virtual table 10c on the flat panel display 10a as shown in the figure.

  Even if comprised in this way, it is also possible to acquire the effect similar to 1st and 2nd embodiment mentioned above. In this example, the object of the present invention can be achieved without using a display with a special table configuration.

  According to the above-described embodiment, the image stored in the device can be directly displayed, and when transferring image data, the image can be clearly shown to the user during the transfer process. Can be reliably transmitted and received without failure.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
