A single-focus projector 100 is mounted on the wall 10 in the Tokyo data room by a metal fitting 30. The camera 300 attached to the ceiling of the document room in Tokyo takes an image of the direction of the wall 10, and the projector 100 transmits the image data taken by the camera 300 to the projector installed in the break room in Osaka. Further, the projector 100 projects an image 20 based on image information transmitted from a projector in Osaka on a wall 10 that is a kind of projection target area. Image 20 shows a state of a break room in Osaka.

  FIG. 2 is an external view of the projector 100 according to the first embodiment. The projector 100 in FIG. 2 shows a state in which the installation state in FIG. 1 is upside down (a state in which the bottom surface is a top surface). The projector 100 includes an imaging unit 114, a projection unit 190, and the like. In the installed state shown in FIG. 1, the imaging unit 114, the projection unit 190, and the like are provided on the slope facing the wall 10 on the bottom surface of the projector 100.

  Next, functional blocks of the projector 100 will be described. FIG. 3 is a functional block diagram of the projector 100 according to the first embodiment. The projector 100 includes a detection unit 110 that detects an operation in the projection target region, a determination unit 120 that determines whether the operation corresponds to the target operation based on detection by the detection unit 110, a storage unit 130, and a communication unit. 140, an update unit 150 that updates data in the storage unit 130, a control unit 160 that performs control according to the target operation when the determination unit 120 determines that the operation corresponds to the target operation, and voice input The unit 170, the audio output unit 180, and the projection unit 190 are configured. In addition, the detection unit 110 includes an imaging unit 114. In addition, the storage unit 130 stores image information 132, imaging information 134, determination data 136, and the like.

  The projector 100 may function as each of these units using the following hardware. FIG. 4 is a hardware block diagram of the projector 100 according to the first embodiment. For example, in the projector 100, the imaging unit 114 is a CMOS camera 920, the determination unit 120, the update unit 150, the control unit 160 is a CPU 910, the storage unit 130 is a RAM 930, the communication unit 140 is a wireless communication unit 940, and a wired communication unit 942. The audio input unit 170 is a microphone 950, a converter 952, etc., the audio output unit 180 is an audio processing circuit 960, an amplifier 962, a speaker 964, etc., and the projection unit 190 is a lamp 980, a liquid crystal panel 982, a liquid crystal drive circuit 984, a lens 986, etc. May be used.

  Next, a procedure for projecting the image 20 in the present embodiment will be described. FIG. 5 is a flowchart showing a projection procedure in the first embodiment. The imaging unit 114 images the wall 10 that is the projection target area, and the update unit 150 stores the imaging information 134 indicating the image captured by the imaging unit 114 in the storage unit 130 (step S1). Note that the imaging range of the imaging unit 114 may be the same range as the image 20, or may include the image 20 and a wider range than the image 20. Further, the projection target area is not limited to the surface of the wall 10, and may be an area away from the wall 10 and close to the wall 10.

  The determination unit 120 determines whether the operation of the employee 60 corresponds to the target operation based on the imaging information 134. For example, the determination unit 120 may determine whether the operation of the employee 60 corresponds to the target operation by using a difference image of the captured images at different times. More specifically, the determination unit 120 determines whether the employee 60 has performed a knocking operation indicating the start of communication (step S2), and determines whether an opening operation indicating the start of image projection has been performed (step S2). S4) It is determined whether or not a closing operation indicating the end of image projection has been performed (step S11). Note that the knocking operation, the opening operation, and the closing operation are target operations to be controlled.

  Here, the knocking operation will be described. FIG. 6 is a diagram showing another example of the projection situation in the first embodiment. For example, as shown in FIG. 6, when the employee 60 performs an operation of hitting the wall 10 twice in succession, it corresponds to the knocking operation being performed in the projection target area. 140 is controlled to start communication with a communication destination projector in Osaka (step S3).

  Next, the opening operation will be described. FIG. 7 is a diagram showing another example of the projection situation in the first embodiment. After the start of communication, when the employee 60 places his / her hand on the wall 10 at the left end of the image for 5 seconds or longer and then moves his / her hand along the wall 10 from left to right, the opening operation has been performed in the projection target area. It corresponds to. When the opening operation is performed, the projection unit 190 projects the image 24 imitating the curtain, and when the employee 60 moves the hand from the left to the right along the wall 10, according to the movement of the hand, An image 21 is projected which gradually increases the area of the image 23 based on the image information 132 and gradually decreases the area of the image 24.

  In this case, the update unit 150 stores the imaging data 135 received from the camera 300 by the communication unit 140 in the storage unit 130 (step S5). In addition, the voice input unit 170 stores voice data 139 indicating the voice of the employee 60 input by the microphone in the storage unit 130 (step S6). Further, the control unit 160 controls the communication unit 140 to transmit the imaging data 135 and the audio data 139 to a communication destination projector (a device corresponding to a knock operation) (step S7). Thereby, the projector in Osaka can project an image showing the employee 60 and output the sound of the employee 60.

  Further, the communication unit 140 receives the image information 132 and the audio information 138 from the communication destination projector, and the update unit 150 stores the information in the storage unit 130 (step S8). The image information 132 is information indicating a captured image obtained by capturing the employee 40, the desk 50, and the like, and the sound information 138 is information indicating the sound of the employee 40.

  The projection unit 190 generates an image based on the image information 132 and projects the image on the wall 10 (step S9). Moreover, the audio | voice output part 180 outputs the audio | voice based on the audio | voice information 138 (step S10).

  Next, the closing operation will be described. FIG. 8 is a diagram showing another example of the projection situation in the first embodiment. For example, when the employee 60 places his / her hand on the wall 10 at the right end of the image for 5 seconds or more after the opening operation and then moves his / her hand along the wall 10 from right to left, the closing operation is performed in the projection target area. It corresponds to that. In this case, the projection unit 190 projects the image 24 imitating a curtain, and when the employee 60 moves the hand from the left to the right along the wall 10, the image information 132 is gradually increased according to the movement of the hand. An image 22 is projected in which the area of the image 23 based on the above is reduced and the area of the image 24 is gradually increased. In this case, the control unit 160 controls the projection unit 190 to end the generation and projection of an image based on the image information 132 (step S12), and the communication unit 140 is a communication destination projector in Osaka. Control to end communication with is performed (step S13).

  As described above, according to the present embodiment, the projector 100 detects an operation in the projection target region and performs control according to the target operation to which the operation is compatible, so that the pointing device such as a remote controller is not used. Image projection control and the like can be performed. Thereby, the projector 100 can activate informal communication. Moreover, since it is sufficient for the observer of the image 20 to always look at the direction of the wall 10, it is possible to concentrate on conversation and the like.

  Further, according to the present embodiment, the projector 100 can perform image projection control or the like according to the opening operation or the closing operation without using an indicator such as a remote controller. Further, according to the present embodiment, the projector 100 can perform communication control according to the knocking operation without using an indicator such as a remote controller.

It can be made.

(Second embodiment)
In the first embodiment, the example in which the projector 100 performs the projection control of the image according to the opening / closing operation of the employee 60 has been described. However, the projector performs the projection control of the image according to the opening / closing operation of the blind using the operation member. You may go. Next, image projection control according to the opening / closing operation of the blind using the operation member will be described.

  FIG. 9 is a diagram illustrating an example of a projection situation in the second embodiment. An operation member 90 that can be rotated is provided outside the image 25 projected by the projector 101, and the rotation operation of the operation member 90 is transmitted to the projector 101 via the transmission member 80. The employee 60 can start and end the projection of the image 25 by rotating the operation member 90. Next, functional blocks of the projector 101 having such functions will be described. FIG. 10 is a functional block diagram of the projector 101 in the second embodiment. The projector 101 includes a detection unit 111 that detects an operation of the operation member 90. Since other configurations are the same as those of the first embodiment, the description thereof is omitted.

  FIG. 11 is a diagram illustrating another example of the projection situation in the second embodiment. FIG. 12 is a diagram showing another example of the projection situation in the second embodiment. For example, when the employee 60 rotates the operation member 90, the detection unit 111 detects the rotation operation, and the determination unit 120 determines an image display method according to the rotation angle by the rotation operation, and performs projection. The unit 190 generates and projects an image according to the display method.

  For example, when the employee 60 rotates the operation member 90 by 90 degrees in the clockwise direction, the projection unit 190 projects the image 26 that is blind and has a half area of the image hidden. For example, when the employee 60 rotates the operation member 90 by 180 degrees clockwise, the projection unit 190 projects the image 27 in which all areas of the effective image are hidden. On the other hand, when the employee 60 rotates the operation member 90 counterclockwise, the projection unit 190 projects an image that is gradually displayed according to the rotation angle.

  As described above, according to the present embodiment, the projector 101 has the same operational effects as the first embodiment. In addition, according to the present embodiment, the projector 101 can perform image projection control according to the rotation operation of the operation member 90 without using an indicator such as a remote controller.

(Other examples)
In addition, application of this invention is not limited to the Example mentioned above, A deformation | transformation is possible. For example, you may combine the structure of the Example mentioned above. In the above-described embodiments, display control is performed on the entire image, but display control may be performed on a part of the image. FIG. 13 is a diagram illustrating an example of the entire image 200 in another embodiment. Moreover, FIG. 14 is a figure which shows another example of the whole image 201 in another Example. For example, the projection unit 190 projects an entire image 200 including an individual image 210 corresponding to the London branch office and an individual image 212 corresponding to the Paris branch office on the wall 10.

  For example, when the employee 60 performs a knocking operation or an opening operation on the individual image 210 displayed on the wall 10, the detection units 110 and 111 perform these operations on the entire image 200 projected on the wall 10. The determination unit 120 determines the target individual image 210 based on the position, and the projection unit 190 indicates the individual image of the rest room of the London branch office according to the determination by the determination unit 120. 211 and the entire image 201 including the individual image 212 are projected. According to this, the projector 100 can perform projection control and the like of desired individual images 210 to 212.

  Moreover, the control part 160 may switch communication object according to opening / closing operation | movement. For example, the communication unit 140 may perform communication with a projector in the London branch office when the opening operation is performed, and may perform communication with a projector in the Paris branch office when the closing operation is performed. Further, in the above-described embodiment, when there is an opening operation and a closing operation, the effective image area is increased or decreased according to the movement of the hand, but the control unit 160, when there is an opening operation or a closing operation, Regardless of the movement of the hand, the area of the effective image may be automatically increased or decreased, and the effective image (when opening) and the invalid image (when closing) may be switched instantaneously. In the above-described embodiment, the projectors 100 and 101 transmit and receive both images and sound. However, only the image information may be transmitted or received, and only the sound information may be transmitted and received.

  The control unit 160 also provides display control information for changing the display of an image on another display device (one or two or more) to the communication unit 140 as control corresponding to the target operation. You may perform control to transmit to. More specifically, for example, the display control information includes information for starting display of an image on the display device according to the knocking operation, turning on the power, and the like, and displaying the image on the display device according to the opening / closing operation of the blind or curtain. The information etc. which perform a start end etc. may be sufficient.

  In addition to the above-described knock operation, opening operation, closing operation, and operation using the operation member 90, the detection unit uses, for example, a contact operation, a separation operation, a shaking operation, a stationary operation, a quick operation, and a body. Thus, an operation for forming a specific shape or the like may be detected as a target operation, and the projection unit 190 may project an image corresponding to these operations. In addition, the detection method of the operation by the detection unit is not limited to the above-described method. A detection method or the like may be used.

  In the second embodiment, the detection unit detects the rotation operation of the operation member 90 via the transmission member 80. However, the detection member captures the operation member or detects the proximity of the operation member. The rotation operation may be detected. For example, when an employee has a pen, the detection unit detects a rotation operation of the pen, and the control unit performs control to start projection of an image to the projection unit according to the rotation operation, Control for terminating the projection of the image may be performed. According to this, since the projector can apply what is in place, such as a pen, as an operation member instead of a special pointing tool, it can activate informal communication.

  When speakers are installed at a plurality of locations on the wall 10, the control unit 160 causes the speaker 40 to output the sound of the employee 40 from the speaker closest to the position of the employee 40 included in the image projected on the wall 10. May be. Similarly, the control unit 160 may control the speaker so that sound can be heard from the position of the speaker in the image in the projection target area using a speaker that has directivity and the output direction can be adjusted. Good.

  The projection target area is not limited to the wall 10 and may be, for example, a screen, a whiteboard, a blackboard, a window glass, a pillar, or the like, and is a three-dimensional space between the projectors 100 and 101 and the projection target. There may be. In addition, when the projection target area is composed of different materials such as windows and pillars, the projection unit 190 adjusts the color and brightness according to the material based on the imaging information from the imaging unit 114 to display the image. You may project. Further, the device corresponding to the knock operation to be communicated is not limited to the projector, and may be a server, a PC (Personal Computer), a television, or the like, for example.

  The computer included in the projectors 100 and 101 may function as the determination unit 120 by reading a program stored in the information storage medium. As such an information storage medium, for example, a CD-ROM, DVD-ROM, ROM, RAM, HDD, or the like can be applied.
