[Description of the configuration of the projection display device]
The optical configuration of the projector 100 in each embodiment of the present invention will be described with reference to FIG.

  Reference numeral 104 denotes a light source unit composed of an arc tube and a parabolic mirror, which is a so-called mercury lamp in the embodiment of the present invention. A light beam from the light source unit 104 enters a color separation / synthesis system 4 including a dichroic mirror DM, a polarization beam splitter PBS, a dichroic prism DP, and the like via an illumination optical system (not shown).

  The illumination optical system (not shown) includes a plurality of fly-eye lens arrays, polarization conversion elements, condenser lenses, and the like, and guides a light beam from the light source unit 104 to a color separation / synthesis system 4 described later.

  The polarization conversion element is configured to convert non-polarized light from the light source unit 104 into polarized light having a specific polarization direction when the light source unit 104 emits a light beam.

  The light beam from the light source unit 104 is decomposed into light of three colors R, G, and B by the dichroic mirror DM and the polarization beam splitter PBS and guided to a liquid crystal panel (light modulation element) (not shown). Then, the light flux from the liquid crystal panel is synthesized by the dichroic prism DP.

  A liquid crystal panel (not shown) forms an original image corresponding to an image signal input from the outside to the projector 100, and modulates light incident on the liquid crystal panel according to the image signal. Modulated light, which is light modulated by the liquid crystal panel, enters the dichroic prism DP via the polarization beam splitter PBS.

  The dichroic prism DP combines the incident RGB three-color modulated light and guides it to the projection lens (projection optical system) 106. The projection lens 106 guides the combined RGB three-color modulated light to a projection surface SC such as a screen. Thereby, the projection image corresponding to the image signal is displayed on the projection surface SC.

[First embodiment]
The first embodiment of the present invention will be described below with reference to FIGS.

  FIG. 2 is a block diagram of the projector (projection display device) 100 shown in FIG.

  The input signal processing unit 101 receives an image signal from the PC 130, and the image processing unit 102 transmits image information obtained by performing image processing on the image signal to the panel driving unit 103.

  The light from the light source unit 104 is modulated by the liquid crystal panel 105 driven by the panel driving unit 103 and projected onto the screen via the projection lens 106.

  Furthermore, the projector 100 includes a first receiving unit 107 that receives a signal from the remote controller 120. Although the first receiver 107 is described as an infrared light receiver, the first receiver 107 is not limited to the infrared light receiver, and may be any device that can receive a signal such as a wireless signal receiver.

  In addition, the projector 100 includes a second receiving unit 109 that acquires information related to a pointing device such as a laser pointer that indicates an arbitrary position. More specifically, the second receiving unit 109 acquires information related to an image on a projected image by light from a laser pointer photographed by the camera 200.

  Note that the second receiving unit 109 is described as acquiring information about an image on a projected image by light from a laser pointer captured by the camera 200, but the configuration of the second receiving unit 109 is limited to this. It is not a thing.

  The second receiving unit 109 does not acquire information regarding an image on the projected image captured by the light from the laser pointer captured by the camera 200, but acquires information regarding a specific image on the projected image captured by the camera 200. It may be a configuration.

  Furthermore, the second receiving unit 109 may be configured to be able to acquire a signal from an input unit different from the remote controller. For example, the second receiving unit 109 acquires a signal from a sound collector such as a microphone. It may be a configuration.

  The processing unit 109 is a control unit that determines a process to be executed from the information received by the first receiver 107 and the information received by the second receiver 109 and executes the determined process.

  FIG. 3 is a schematic diagram of this embodiment. Although only the projector 100 is illustrated in FIG. 3, in the present embodiment, it is assumed that there are a plurality of projectors other than the projector 100 and the plurality of projectors are operated by one remote controller 120.

  The user can operate the projector 100 using the remote controller 120. Specifically, when the user presses a button corresponding to a specific operation of the remote controller 120, a code corresponding to the specific operation is displayed on the projector. 100.

  When the projector 100 is projecting the projection image 131, if the user displays the pointer 132 on the projection image 131 with a laser pointer (not shown), the projector 100 performs processing corresponding to the code from the remote controller 120. Run.

  With reference to FIG. 4, processing associated with the remote controller operation will be described.

  First, when the projector 100 is activated, the projector 100 waits for reception of a code from the remote controller 120 (step S201). Note that the reception waiting state may be canceled after a specific time has elapsed, and when the user presses any button provided on the remote controller 120 or the projector 100, the reception waiting state may be taken again.

  If reception of the code from the remote controller 120 can be confirmed in step S201, the camera 200 captures the projection image 131 (step S202). If the pointer 132 is detected on the projected image 131 as a result of step S202, the processing unit 109 performs processing corresponding to the code from the remote controller 120.

  On the other hand, if the pointer 132 is not detected on the projected image 131 as a result of step S202, the processing unit 109 does not perform processing corresponding to the code from the remote controller 120.

  That is, the flowchart shown in FIG. 4 is a control method for controlling the projector 100.

  In this control method, a first acquisition step (S201) for acquiring a signal from a remote controller which is a first input means, and a second for acquiring a signal from a second input means different from the remote controller. Acquisition step (S202).

  Further, the control method includes a control step (S203) of controlling the electronic device based on the acquisition result in the first acquisition step when the signal from the second input unit is acquired in the second acquisition step. Prepare.

  In other words, the flowchart shown in FIG. 4 is a control method for controlling the first projection display device and the second projection display device.

  The control method includes a first acquisition step (S201) for acquiring a signal from the remote controller, a first projection image from the first projection display apparatus, and a second projection display apparatus. A shooting step of shooting the second projected image;

  Furthermore, this control method includes a first determination step (S202) for determining whether or not the photographing result of the photographing step is a predetermined result.

  Consider a case where the first determination step determines that the result of shooting in the shooting step is a predetermined result. In this case, the control method shown in FIG. 4 includes a control step (S203) for controlling at least one of the first projection display device and the second projection display device based on the acquisition result of the first acquisition step.

[Second Embodiment]
A second embodiment of the present invention will be described with reference to FIG.

  In the first embodiment described above, in this embodiment, reception of a code from the remote controller 120 is used as a processing start key. However, in the present embodiment, the detection of the pointer 132 is used as a processing start key, and after the pointer is detected, the reception of a code from the remote controller is waited for a predetermined time.

  Specifically, as shown in FIG. 5, first, the camera 200 captures the projected image 131 and determines whether or not the pointer 132 is on the projected image 131 (steps S221 to S222). If the pointer 132 is not detected, the camera 200 captures an image again.

  When the pointer 132 is detected, a time measurement unit (third acquisition unit) (not shown) starts measuring elapsed time with the time when the pointer 132 is detected as 0 seconds, and receives a code from the remote controller 120. Is determined (steps S223 to S224).

  If reception of the code cannot be confirmed, it is determined whether or not a specific time has elapsed (step S226). If the specific time has not elapsed, it is determined whether the code has been received again, and if reception of the code is confirmed, processing corresponding to the code is executed (step S225). On the other hand, when the reception of the code cannot be confirmed and a specific time has elapsed, the camera 200 captures an image again.

  That is, the flowchart shown in FIG. 5 is a control method for controlling the projector 100.

  In this control method, when the signal from the camera (second input means) 200 is acquired in the second acquisition step (S222), the signal from the camera 200 is acquired in the second acquisition step. The third acquisition step (S223) for acquiring the time is provided.

  Furthermore, this control method includes a determination step (S226) for determining whether the acquisition result obtained in the third acquisition step is within a predetermined time.

  A case is considered in which it is determined in the determination step that the acquisition result in the third acquisition step is within a predetermined time, and a signal from the remote controller is acquired in the first acquisition step (S224). In this case, the control step (S225) controls the projector 100 based on the acquisition result obtained in the first acquisition step.

  On the other hand, a case is considered in which it is determined in the determination step that the acquisition result in the third acquisition step has exceeded a predetermined time, and the first acquisition step has not acquired a signal from the remote controller.

  In this case, the second acquisition step acquires the signal from the camera 200 again.

  As described above, in this embodiment, the projector 100 includes a time measurement unit that acquires the time after the second reception unit 109 acquires the signal from the camera 200. Then, the processing unit 108 is based on the signal from the remote controller 120 when the acquisition result by the time measurement unit is within a predetermined time and the first reception unit 107 acquires the signal from the remote controller 120. Projector 100 is controlled. Furthermore, the camera 200 receives a signal from the second receiving unit 109 when the acquisition result by the time measuring unit exceeds a predetermined time and the first receiving unit 107 does not acquire a signal from the remote controller 120. Get the signal.

  That is, a standby state is waited for a code from the remote controller 120 until the specific time has elapsed, and the standby state is canceled when the characteristic time has elapsed.

  Consider a case where a plurality of projectors are used and the standby state continues to be taken even after a specific time has elapsed unlike the configuration of the present embodiment.

  In this case, it is assumed that a plurality of projectors wait for a code from the remote controller 120 after the specific time has elapsed, and the user operates the remote controller 120 in such a situation. Then, although the user wants to operate a certain projector, a plurality of projectors are operated at the same time, and there is a possibility that an adjustment not intended by the user is performed.

  As shown in the present embodiment, a standby state in which a code from the remote controller 120 is waited until a specific time has elapsed, and the standby state is canceled when the characteristic time has elapsed. Thereby, it becomes possible to suppress that the adjustment which the above-mentioned user does not intend is performed.

  Further, in the present embodiment, similarly to the first embodiment described above, when the user wants to change the projector that the user wants to operate, the operation performed by the user using the remote controller is suppressed and the burden on the user is reduced. This can be further reduced.

  In the present embodiment, the configuration for determining whether or not the specific time has elapsed when the reception of the code from the remote controller 120 cannot be confirmed is illustrated, but the present embodiment is not limited to this. . When the reception of the code from the remote controller 120 cannot be confirmed, the pointer is detected again. As a result, when the pointer is detected, the elapsed time may be reset and the time measurement may be started again. .

  Further, in the present embodiment, the configuration in which imaging of the projected image 131 by the camera 200 is repeated until the pointer is detected is illustrated, but the present invention is not limited to this. For example, if the pointer 132 cannot be detected on the projected image 131 even after the camera 200 has taken a specific number of times, the flow shown in FIG. 5 is ended, and the camera is again displayed after a specific time has elapsed since the end of the flow. The configuration may be such that 200 projects the projected image 131.

[Third embodiment]
A third embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 6, the present embodiment is an embodiment relating to a PbyP (Picture by Picture) system in which the projector 100 divides the projected image 131 into two and displays the left side 141 and the right side screen 142 individually.

  The upper left corner of the projected image 131 is the origin, the lower direction is the y-axis direction, and the horizontal direction is the x-axis direction. At this time, the projected image 131 is a region where the region where the x coordinate is 0 to xmax and the region where the y coordinate is 0 to ymax overlap.

  Further, the left screen 141 is a region where the region where the x coordinate is 0 to xhalf and the region where the y coordinate is 0 to ymax is the left screen 141, the region where the x coordinate is xhalf to xmax, and the region where the y coordinate is 0 to ymax. The area where the two overlap is the right screen 142.

  However, when the projector is not a desk surface but is suspended so that the bottom surface of the projector faces the ceiling, the definitions of the y-axis direction and the x-axis direction may be appropriately changed.

  As shown in FIG. 7, the process is the same as that in the first embodiment until a code is received from the remote controller 120 and the camera 200 picks up the projected image 131 and detects whether the pointer 132 is present (step). S201-203).

  When the pointer 132 is detected, in the present embodiment, the coordinates (x, y) of the pointer 132 are detected (step S231).

  Next, it is determined whether the pointer coordinates detected in step S231 are on the left screen 141 or the right screen 142. Specifically, when the coordinate x in the x-axis direction of the pointer 132 satisfies 0 ≦ x ≦ xhalf and the coordinate y in the y-axis direction of the pointer 132 satisfies 0 ≦ y ≦ ymax, the pointer 132 is on the left side. It is determined that the image is on the screen 141 (steps S232 to S233).

  If it is determined that the pointer 132 is on the left screen 141, processing corresponding to the code from the remote controller 120 is performed on the left screen 141 (step S234). That is, when the user wants to adjust the brightness or the like of the left screen 141, the remote controller 120 may be operated with the pointer displayed on the left screen 141.

  On the other hand, when the coordinate x in the x-axis direction of the pointer 132 satisfies xhalf <x ≦ xmax and the coordinate y in the y-axis direction of the pointer 132 satisfies 0 ≦ y ≦ ymax, the pointer 132 is displayed on the right screen 142. (Steps S235 to S236).

  If it is determined that the pointer 132 is on the right screen 142, processing corresponding to the code from the remote controller 120 is performed on the right screen 142 (step S237). That is, when the user wants to adjust the brightness or the like of the right screen 142, the remote controller 120 may be operated after the pointer is displayed on the right screen 142.

  Note that the coordinate x in the x-axis direction of the pointer 132 satisfies 0 ≦ x ≦ xhalf, but the coordinate y in the y-axis direction of the pointer 132 does not satisfy 0 ≦ y ≦ ymax, that is, the pointer 132 is from the projected image 131. Let us consider the case where the signal is detected outside.

  In such a case, the processing corresponding to the code from the remote controller 120 is not performed on either the left screen 141 or the right screen 142.

  The coordinate x in the x-axis direction of the pointer 132 satisfies xhalf <x ≦ xmax, but the same applies when the coordinate y in the y-axis direction of the pointer 132 does not satisfy 0 ≦ y ≦ ymax. The same applies to the case where the coordinate x of the pointer 132 in the x-axis direction does not satisfy 0 ≦ x ≦ xhalf and xhalf <x ≦ xmax.

  Note that xhalf, xmax, and ymax excluding the pointer coordinates may be stored in a storage unit (not shown), and each coordinate may be acquired by the camera 200 capturing the projected image 131.

  That is, the flowchart shown in FIG. 7 is a control method for controlling a plurality of projectors.

  In this control method, in the first determination step (S203), it is determined that the shooting result of the predetermined region of the first projection image or the second projection image in the shooting step (S202) is a predetermined result. Think about the case.

  In this case, the control steps (S234, S237) control at least one of the first projection display device and the second projection display device based on the acquisition result of the first acquisition step.

  Thus, in the present embodiment, the control means, when the second acquisition means acquires that the predetermined area of the projection image is in the predetermined state, the projection display based on the signal from the remote controller. Control the device. More specifically, the control means controls the state of the image displayed in the predetermined area based on a signal from the remote controller.

  Here, the control means is the processing unit 108, and the second acquisition means is the second reception unit 109. The predetermined state indicates a state in which an image by light from the laser pointer is displayed.

  With the above-described configuration, it is to provide an electronic device that can further reduce the burden on the user even in the PbyP method.

  On the other hand, if the user wants to change the screen operated by the remote controller 120 when the above-described configuration is not applied in the PbyP method, for example, the user needs to select the screen to be adjusted by operating the remote controller. That is, the operation performed by the user using the remote controller becomes complicated, and there is a possibility that the burden on the user increases.

  In the present embodiment, the configuration in which the pointer position is detected with the upper left corner of the projected image 131 as the origin is illustrated, but the present invention is not limited to this, and the origin of the pointer position may be changed as appropriate.

  Also in the case of the PinP (Picture in Picture) method, it is possible to apply a configuration in which the screen to be operated is selected by determining whether the coordinates of the pointer are within a predetermined range, as in this embodiment. preferable.

  In the present embodiment, reception of a code from the remote controller has been described as a processing start key. However, as in the second embodiment described above, the detection of the pointer may be used as a processing start key to wait for reception of a code from the remote controller for a predetermined period after the pointer is detected.

[Fourth embodiment]
A fourth embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 8, the present embodiment is an embodiment relating to stack projection in which the master projector 100 is installed on the slave projector 300 and the projection images from both projectors are superimposed.

  The master projector 100 and the slave projector 300 are wired with a cable 400, but may be wirelessly connected.

  Further, a button for transmitting information for starting stack projection to the master projector 100 may be provided on the master projector 100 or the remote controller 120. As a result, the master projector 100 can acquire information indicating that it is performing stack projection.

  The camera (photographing means) 200 as the second input means is provided integrally with the master projector 100, but the camera 200 may be provided integrally with the slave projector 300. Furthermore, both the master projector 100 and the slave projector 300 may have the camera 200. Alternatively, the camera 200 is provided separately from the master projector 100 and the slave projector 300, and may be provided on a ceiling or the like.

  As shown in FIG. 9, the process is the same as in the first embodiment until a code is received from the remote controller 120 and the camera 200 picks up the projected image 131 and detects whether the pointer 132 is present (step). S201-203).

  When the pointer 132 is detected, in this embodiment, it is determined whether or not there is a pointer above the center line C shown in FIG. 8 (step S241). If detected above the center line C, the master projector 100 executes processing corresponding to the code from the remote controller 120. That is, when the user wants to operate the master projector 100, a pointer may be displayed above the projected image.

  The center line C is a center line that equally divides the projected image 131 vertically. In this embodiment, the upper side indicates the ceiling direction, and the lower side indicates the floor surface direction.

  However, when the projector is not a desk surface and is suspended so that the bottom surface of the projector faces the ceiling, the definitions of the upper side and the lower side may be changed as appropriate.

  On the other hand, when the pointer is detected below the center line C, the slave projector 300 executes processing corresponding to the code from the remote controller 120 (step S244). That is, when the user wants to operate the slave projector 300, a pointer may be displayed below the projected image.

  That is, the flowchart shown in FIG. 9 is a control method for controlling a plurality of projectors.

Although not shown, this control method is a first transmission that tells at least one of the master projector (first projection display device 100 and slave projector (second projection display device) 300 to perform stack projection. Comprising steps.

  Then, when a region where at least a part of the first projection image and the second projection image overlap is set as a superposition region, the photographing result of the predetermined region of the superposition region in the photographing step (S202) is a predetermined result. Consider a case.

  In this case, the control step (S242, S244) controls which of the first projection display device and the second projection display device corresponds to a predetermined area.

  Thus, in the present embodiment, the projection display device is a first projection image from the projection display device and a second projection image from a second projection display device different from the projection display device. Acquires information indicating that the image is displayed on the projection surface. Furthermore, the projection display apparatus acquires information indicating that a part of the first projection image and the second projection image overlap each other.

  Then, a region where at least a part of the first projected image and the second projected image overlap is set as a superimposed region, and the second acquisition means indicates that the predetermined region of the superimposed region is in a predetermined state. Get information.

  In the above case, the control means controls the projection display device based on the signal from the remote controller.

  Here, the projection display device is the master projector 100, and the second projection display device is the slave projector 300. The first projection image is a projection image from the master projector 100, and the second projection image is a projection image from the slave projector 300.

  The superimposition area is a projection image 131 in which the projection image from the master projector 100 and the projection image from the slave projector 300 are displayed in an overlapping manner. For this reason, the predetermined area of the overlapping area indicates a predetermined area of the projection image 131. Specifically, the upper side of the projected image 131 with respect to the center line C is set as a predetermined area, and when this area is in a predetermined state, the processing unit in the master projector 100 performs processing based on a signal from the remote controller 120. I do. The predetermined state indicates a state in which an image by light from the laser pointer is displayed.

  With the above-described configuration, it is an object to provide an electronic device that can further reduce the burden on the user even during stack projection.

  On the other hand, when the user wants to change the projector operated by the remote controller 120 when the above-described configuration is not applied at the time of stack projection, for example, the user needs to change the number of the remote controller to match the number of the projector to be operated. There is. That is, the operation performed by the user using the remote controller becomes complicated, and there is a possibility that the burden on the user increases.

  In the present embodiment, the configuration in which the center line C is divided into the upper side and the lower side is illustrated as an example. A configuration that can be set may be used.

  In the present embodiment, reception of a code from the remote controller has been described as a processing start key. However, as in the second embodiment described above, the detection of the pointer may be used as a processing start key to wait for reception of a code from the remote controller for a predetermined period after the pointer is detected.

[Fifth embodiment]
A fifth embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 10, the present embodiment is an embodiment related to multi-projection in which a projection image 131L from the left projector 100L and a projection image 131R from the right projector 100R are connected and displayed. The left projector 100L and the right projector 100R are wirelessly connected, but may be wired.

  Further, a button for transmitting information for starting multi-projection to the left projector 100L may be provided on the left projector 100L or the remote controller 120. As a result, the left projector 100L can acquire information indicating that it is performing multi-projection.

  Edge blending is generally performed when performing multi-projection. When the left projection image 131L and the right projection image 131R are adjacent to each other without overlapping, a slight gap between the two projection images becomes conspicuous. Further, in order to eliminate such a slight gap, fine adjustment is required. Therefore, when performing multi-projection, the left projection image 131L and the right projection image 131R can be overlapped to eliminate the aforementioned gap. However, when both the left projection image 131L and the right projection image 131R have uniform brightness over the entire projection image, only the region where both projection images overlap is brighter than the other regions.

  Therefore, the right end portion of the left projection image 131L is darker than the other regions of the left projection image 131L, and the left end portion of the right projection image 131R is darker than the other regions of the right projection image 131R, so that both projection images are superimposed. . This makes it possible to display a projected image with uniform brightness during multi-projection.

  More specifically, the right end portion of the left projected image 131L is gradually darkened according to a predetermined function as it approaches the right end of the left projected image 131L. Further, the left end portion of the right projection image 131R gradually becomes dark according to a predetermined function as it approaches the left end of the right projection image 131R.

  In the present embodiment, as shown in FIG. 10, an area where the right end portion of the left projection image 131L and the left end portion of the right projection image 131R overlap is shown as an edge blending region EB. That is, the right end portion of the left projection image 131L is a portion of the left projection image 131L that overlaps with the right projection image 131R. The left end portion of the right projection image 131R is a portion that overlaps the left projection image 131L in the right projection image 131R.

  As shown in FIG. 11, the process is the same as in the first embodiment until a code is received from the remote controller 120 and the camera 200 picks up the projected image 131 and detects whether the pointer 132 is present (step). S201-203).

  When the pointer 132 is detected, in this embodiment, it is determined whether or not the pointer 132 is on the area EB (step S251). When the pointer 132 is detected on the area EB, neither the left projector 100L nor the right projector 100R performs processing based on the code from the remote controller 120.

  On the other hand, when the pointer 132 is not detected on the area EB, it is determined whether or not the pointer 132 is on the left projected image 131L excluding the area EB (step S252). When the pointer 132 is detected in the left projected image 131L excluding the area EB, the left projector 100L executes a process corresponding to the code from the remote controller 120 (step S253).

  That is, when the user wants to operate the left projector 100L, the remote controller 120 may be operated after displaying a pointer on the left projected image 131L excluding the area EB.

  On the other hand, if the pointer 132 is not detected on the left projected image 131L excluding the area EB, it is next determined whether or not there is a pointer on the right projected image 131R excluding the area EB (step S254). When the pointer 132 is detected in the right projected image 131R excluding the area EB, the right projector 100R executes a process corresponding to the code from the remote controller 120 (step S255).

  That is, when the user wants to operate the right projector 100R, the pointer may be displayed on the right projected image 131R excluding the area EB and the remote controller 120 may be operated.

  When the pointer 132 is not detected in any of the area EB, the left projection image 131L, and the right projection image 131R, neither the left projector 100L nor the right projector 100R performs processing based on the code from the remote controller 120.

  That is, the flowchart shown in FIG. 11 is a control method for controlling a plurality of projectors.

  Although this control method is not shown in the drawing, a second projection that tells at least one of the left projector (first projection display device) 100L and the right projector (second projection display device) 100R to perform multi-projection. A transmission step is provided.

  A region where at least a part of the first projected image and the second projected image overlap is defined as a superimposed region. At this time, when the shooting result of the first projection image excluding the overlapping region in the shooting step (S202) is a predetermined result, the control steps (S253, S255) control the left projector 100L.

  On the other hand, when the shooting result of the second projection image excluding the overlapping region in the shooting step (S202) is a predetermined result, the control steps (S253, S255) control the right projector 100R.

  Thus, in the present embodiment, the projection display device is a first projection image from the projection display device and a second projection image from a second projection display device different from the projection display device. Acquires information indicating that the image is displayed on the projection surface. Furthermore, the projection display apparatus acquires information indicating that a part of the first projection image and the second projection image overlap each other.

  Then, a region where at least a part of the first projection image and the second projection image overlap is defined as a superimposition region, and the second acquisition unit determines that a region excluding the superimposition region in the first projection image is a predetermined region. Acquires information indicating the state.

  In the above case, the control means controls the projection display device based on the signal from the remote controller.

  In the present embodiment, the projection display device is the left projector 100L, the first projection image is the left projection image 131L, and the second projection display device is the right projector 100R, and the second projection. The image is the right projected image 131R.

  Further, the overlapping area is the edge blending area EB. The predetermined area being in the predetermined state indicates a state in which an image by light from the laser pointer is displayed on the area.

  With the above-described configuration, it is an object to provide an electronic device that can further reduce the burden on the user even during multi-projection.

  On the contrary, when the user wants to change the projector operated by the remote controller 120 when the above configuration is not applied at the time of multi-projection, for example, the user needs to change the ID of the remote controller to match the ID of the projector to be operated. There is. That is, the operation performed by the user using the remote controller becomes complicated, and there is a possibility that the burden on the user increases.

  In the present embodiment, the configuration in which neither the left projector 100L nor the right projector 100R performs the process based on the code from the remote controller 120 when the pointer 132 is detected on the area EB is illustrated. However, the present embodiment is not limited to this. When the pointer 132 is detected on the area EB, for example, both the left projector 100L and the right projector 100R perform processing based on the code from the remote controller 120. May be performed. In such a configuration, when the user wants to adjust the brightness or the like of the composite projected image 131M, the user may operate the remote controller 120 after displaying a pointer on the area EB.

  In the present embodiment, reception of a code from the remote controller has been described as a processing start key. However, as in the second embodiment described above, the detection of the pointer may be used as a processing start key to wait for reception of a code from the remote controller for a predetermined period after the pointer is detected.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
