Japanese Patent Laid-Open No. 8-223591 (page 7, FIG. 1)

  However, the above display device has the following problems. That is, in this display device, it is possible to operate a plurality of displays with one remote controller by setting IDs in advance on the display and the remote controller. However, for example, when the ID of the display to be set to “1” is set to “5” by mistake, not only the display cannot be operated, but also the cause of the inability to operate is due to an ID setting error. Nevertheless, since it is difficult for the user to recognize this, there is a risk that the user may be misunderstood as if the cause of the inoperability is due to a failure. Even if the user recognizes that the ID setting is incorrect, it may be necessary to reset the IDs of all the display devices because it is difficult to know the set IDs.

  The present invention has been made in view of such problems, and it is a main object of the present invention to provide a display control device, a projector, and a display control method capable of eliminating the disadvantages when operating a plurality of display units using an operation device. Objective.

  In order to achieve the above object, a display control device according to the present invention is a display control device including a control unit that causes a display unit to perform display processing in accordance with an operation signal output from an operation device, wherein the control unit includes: The first identification information that is output from the operation device together with the operation signal and designates the display unit to be operated and the second identification information set in the display unit are informed of a mismatch. And a notification process for displaying on the display unit at least one of the notification image and the second notification image that indicates that the identification information matches.

  The display control method according to the present invention is a display control method for causing a display unit to perform display processing according to an operation signal output from an operation device, and is output from the operation device together with the operation signal to be operated. A first notification image for informing that the first identification information for designating the display unit and the second identification information set in the display unit do not match, and that the two identification information match. A notification process for displaying at least one of the second notification images to be notified on the display unit is executed.

  According to the display control device and the display control method, the first notification image that notifies that the first identification information that designates the display unit to be operated does not match the second identification information set in the display unit. And performing a notification process for displaying on the display unit at least one of the second notification images informing that the identification information matches, for example, when operating a plurality of display units using the operation device Thus, it is possible to make the user confirm at a glance information such as the state of coincidence and mismatch of the identification information and which display unit among the display units is set as the operation target. For this reason, for example, when an operation on a desired display unit cannot be performed due to a setting error of the first identification information or the second identification information, there is a disadvantage that the user is misunderstood as to whether the cause is due to a failure. It can be surely prevented. Further, by displaying both set identification information in the first notification image and the second notification image, when there is an error in setting the first identification information or the second identification information, the error is displayed. It can be easily corrected (changed). For this reason, it is possible to reliably eliminate the inconvenience of resetting the second identification information in all the display units due to the difficulty of knowing both set identification information.

  In the display control device according to the present invention, when the control unit sequentially outputs a first control signal and an instruction signal for instructing power supply from the operation device, the power supply processing for the display unit is performed. Execute.

  According to this display control device, when the first control signal and the instruction signal for instructing power supply are sequentially output from the operation device, the power supply processing for the display unit is performed regardless of the coincidence or mismatch of the identification information. By executing, unlike the general configuration where processing for all operation signals is not executed when both identification information does not match, power is reliably supplied to the display even if both identification information does not match Thus, the first notification image and the second notification image can be reliably displayed.

  In the display control device according to the present invention, when the control unit sequentially outputs the second control signal and the operation signal from the operation device, the control unit executes the display process according to the operation signal, and When the control signal is not output, the display process is executed according to the operation signal only when the two identification information matches.

  According to this display control device, when the second control signal and the operation signal are sequentially output from the operation device, the display process is executed according to the operation signal regardless of the coincidence and mismatch of both identification information, and the second control signal Is not output, by performing display processing according to the operation signal only when the two identification information matches, for example, when operating a plurality of display units using the operating device, Usage that emphasizes efficiency, such as performing predetermined operations all at once, and usage that emphasizes security so that certain operations can be performed only on specific display units to restrict operations by others. It can be easily switched depending on whether or not the second control signal is transmitted. For this reason, it can respond to a user's usage form flexibly.

  In the display control device according to the present invention, the control unit stops the execution of the notification process when a third control signal is output from the operating device.

  According to the display control device, when the third control signal is output from the controller device, the display of the first notification image and the second notification image is not required by stopping the execution of the notification process. Since the display of both notification images can be arbitrarily stopped by simply outputting the third control signal, both notification images are displayed each time the operation is performed on the display unit. It is possible to reliably prevent a situation where the original image is difficult to see.

  Moreover, the display control apparatus according to the present invention executes the notification process only when the control unit is in a notification process permission state when a fourth control signal is output from the operation device.

  According to this display control device, the first notification image and the second notification image are executed by executing the notification processing only when the fourth control signal is output from the operation device and the notification processing is permitted. Both notification images can be arbitrarily displayed by outputting the fourth control signal only when the display is necessary. Therefore, when the operation is repeatedly performed on the display unit, It is possible to reliably prevent a situation where the notification image is displayed and the original image becomes difficult to see.

  In the display control device according to the present invention, the control unit displays the first notification image and the second notification image in different display colors when the notification process is executed.

  According to this display control device, when the notification process is executed, the first notification image and the second notification image are displayed in different display colors, so that the first notification image can be displayed even at a position away from the display position. And the second notification image can be clearly distinguished and visually recognized, so that it can be surely recognized whether or not the first identification information and the second identification information match.

  In the display control device according to the present invention, when the control unit does not match the first identification information and the second identification information, at least of the first identification information and the second identification information. A change screen for changing one is displayed on the display unit.

  According to the display control device, the change screen for changing at least one of the first identification information and the second identification information when the first identification information and the second identification information do not match is provided. By displaying on the display unit, the second identification information set on the display unit by operating the operation device using the change screen without operating the operation unit provided on the display unit from a position away from the position. Since it can be changed, the convenience for the user can be sufficiently improved.

  The display control device according to the present invention further includes a storage unit that stores operation target information that can be specified as an operation target, and the control unit outputs the operation signal from the operation device and the first control unit. When the identification information is not output together with the operation signal, the notification process is executed based on the operation target information stored in the storage unit.

  According to this display control device, when the first identification information is not output together with the operation signal, the notification device performs the notification process based on the operation target information stored in the storage unit, for example, so that the operation device Even when it does not have a function of outputting one identification information, both notification images can be displayed, and thus the same effect as described above can be realized.

  A projector according to the present invention includes the display control device described above and the display unit controlled by the display control device.

  According to the projector, by providing the display control device and the display unit, it is possible to realize the same effect as that of the display control device.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, best modes of a display control device, a projector, and a display control method according to the invention will be described with reference to the accompanying drawings. A projector 1 shown in FIG. 1 is an example of a projector according to the present invention, and as shown in FIG. 1, a control unit 11, a data input unit 12, an image processing unit 13, a projection unit 14, a transmission / reception unit 15, an operation unit. 16, the 1st memory | storage part 17 and the 2nd memory | storage part 18 are comprised. In this case, the control unit 11, the image processing unit 13, the transmission / reception unit 15, the operation unit 16, the first storage unit 17, and the second storage unit 18 constitute a display control apparatus according to the present invention.

  The control unit 11 operates in accordance with an operation program recorded in the first storage unit 17, and an operation signal So and a control signal Sc transmitted (output) from a remote controller 2 (hereinafter also referred to as “remote controller 2”) described later. In accordance with the control, each component constituting the projector 1 is controlled. Further, the control unit 11 causes the projection unit 14 to project and display various images (for example, the images Gpa to Gpd illustrated in FIG. 5) by executing the display control process 50 illustrated in FIG. 6. In addition, when a predetermined condition is satisfied when the display control process 50 is executed, the control unit 11 executes the notification process 60 shown in FIG. 7 to thereby generate the notification image Gi1 (see FIG. 8) and the notification image Gi2 ( (See the same figure) is projected and displayed on the projection unit 14. In this case, the notification image Gi1 corresponds to the first notification image in the present invention, and is an ID (first identification information in the present invention: hereinafter referred to as the remote control 2) that is set in the remote controller 2 and specifies the projector 1 to be operated. The ID that is set is also referred to as “ID1” and the ID that is set in the projector 1 and identifies the projector 1 (second identification information in the present invention: hereinafter, the ID that is set in the projector 1 is also referred to as “ID2”). ) Are displayed in a case where they do not match (when they are different), and are composed of character information or the like for notifying that both IDs 1 and 2 do not match. The notification image Gi2 corresponds to the second notification image in the present invention, and is an image that is displayed when both ID1 and ID2 match, and notifies that both ID1 and ID2 match. It consists of character information and so on.

  For example, as shown in FIG. 4, the data input unit 12 is connected to a computer 100 as an external device via a USB cable 200 and inputs image data Dg transmitted from the computer 100. The image processing unit 13 generates display data De for image display based on the image data Dg input from the external device via the data input unit 12. The projection unit 14 corresponds to the display unit in the present invention, and includes a light source, a light modulation element, and a projection lens, and the projection light L that is light-modulated based on the display data De generated by the image processing unit 13. Project.

  The transmission / reception unit 15 receives the infrared signal Si output from the remote controller 2 and outputs the operation signal So, the control signal Sc, and the identification data Dd1 to the control unit 11. The operation unit 16 is configured by arranging various switches and keys such as a power switch and an ID setting key (not shown), and when these are operated, an operation signal So corresponding to the operated switch or key. Is output to the control unit 11. The first storage unit 17 stores an operation program for the control unit 11. The first storage unit 17 stores notification image data Di used for displaying the notification images Gi1 and Gi2 and change screen data Ds used for displaying a change screen Gs described later. The second storage unit 18 stores identification data Dd2 indicating ID2 described above according to the control of the control unit 11.

  On the other hand, the remote controller 2 shown in FIGS. 2 and 3 corresponds to the operating device in the present invention, and includes an operating unit 21, a control unit 22, a storage unit 23, and a transmitting / receiving unit 24 as shown in FIG. As shown in FIG. 3, the operation unit 21 includes a power key 31, a simultaneous operation key 32, a display start key 33, an ID setting key 34, numeric keys 35, 35..., A color tone change key 36, a cursor key 37, a white balance. Various switches and keys such as the change key 38, the notification display prohibition key 39, and the setting screen display key 40 are arranged, and when these are operated, the operation signal So corresponding to the operated switch or key is displayed. The control signal Sc is output to the control unit 22. The storage unit 23 stores identification data Dd1 indicating ID1 described above according to the control of the control unit 22. The transmission / reception unit 24 transmits an infrared signal Si corresponding to the operation signal So, the control signal Sc, and the identification data Dd1.

  Next, an example of a method of projecting and displaying an image by operating, for example, four projectors 1 (projectors 1a to 1d shown in FIG. 4) with one remote controller 2, and the entire projector 1 and remote controller 2 at that time Various operations will be described with reference to the drawings.

  In this example, in order to operate each projector 1a-1d with one remote controller 2, ID2 for identifying each projector 1a-1d is set in advance. Specifically, an ID setting key in the operation unit 16 of each projector 1a to 1d is operated to set ID2 of each projector 1a to 1d to 1 to 4, for example. In this case, the control unit 11 of each projector 1a to 1d causes the second storage unit 18 to store identification data Dd2 indicating the set ID2. Next, as shown in FIG. 5, the projectors 1 a to 1 d are arranged facing the screen 300, and then, as shown in FIG. 4, the computer 100 and each projector 1 a as an external device serving as a source of the image data Dg. ˜1d data input unit 12 is connected by USB cable 200. Subsequently, the image data Dg is output from the computer 100.

  Next, for example, when turning on the power of the projectors 1a to 1d all at once, the power key 31 is operated after the simultaneous operation key 32 in the operation unit 21 of the remote controller 2 is operated. At this time, the operation unit 21 controls the control signal Sc corresponding to the simultaneous operation key 32 (the control signal Sc at this time corresponds to the first control signal in the present invention, and hereinafter also referred to as “control signal Sc1”), and The operation signal So corresponding to the power key 31 (instruction signal for instructing power supply in the present invention) is sequentially output, and the transmission / reception unit 24 transmits the infrared signal Si corresponding to both the control signals Sc. On the other hand, in each projector 1a to 1d, the transmission / reception unit 15 receives the infrared signal Si and corresponds to the signal corresponding to the infrared signal Si, that is, the control signal Sc1 corresponding to the simultaneous operation key 32 of the remote controller 2 and the power key 31. The operation signal So is output in order.

  In this case, since the control signal Sc corresponding to the simultaneous operation key 32 is output (transmitted from the remote controller 2), the control unit 11 of each projector 1a to 1d supplies power to the projection unit 14 according to the control signal Sc corresponding to the power key 31. Execute the supply process. Next, the control unit 11 reads the operation program from the first storage unit 17 and executes the display control processing 50 shown in FIG. 6 according to the operation program. In the display control process 50, the control unit 11 determines whether or not the operation signal So is output from the transmission / reception unit 15 (that is, the remote controller 2) (step 51). In this case, when the operation signal So is not output, the control unit 11 repeatedly executes step 51.

  On the other hand, for example, when images based on the image data Dg from the computer 100 are simultaneously projected and displayed on the projectors 1a to 1d, the display start key 33 is operated after the simultaneous operation key 32 in the operation unit 21 of the remote controller 2 is operated. To do. At this time, the operation unit 21 controls the control signal Sc corresponding to the simultaneous operation key 32 (the control signal Sc at this time corresponds to the second control signal in the present invention, and hereinafter also referred to as “control signal Sc2”), and The operation signal So corresponding to the display start key 33 is sequentially output, and the transmission / reception unit 15 of each projector 1a to 1d receives the infrared signal Si from the remote controller 2 and receives the control signal Sc2 and the operation signal corresponding to the display start key 33. So is output in order. Next, the control unit 11 determines in step 51 of the display control process 50 that the operation signal So has been output, and then determines whether or not the control signal Sc2 has been output together with the operation signal So (step). 52).

  In this case, since the control signal Sc2 is output, the control unit 11 executes a process according to the operation signal So (step 53). Specifically, the control unit 11 transfers the image data Dg from the computer 100 input via the data input unit 12 to the image processing unit 13 in accordance with the operation signal So. Next, the image processing unit 13 generates display data De for image display based on the image data Dg, and the control unit 11 outputs the display data De to the projection unit 14. Subsequently, the projection unit 14 projects the projection light L that is light-modulated based on the display data De. Thereby, as shown in FIG. 5, the images Gpa to Gpd are displayed on the screens 300 by the projection of the projection light L from the projectors 1a to 1d, respectively.

  Next, for example, when only the color tone of the image Gpa projected and displayed by the projector 1a is changed without changing the color tone of the images Gpb to Gpd projected and displayed by the projectors 1b to 1d, only the projector 1a is set as the operation target. In order to do this, ID 1 is set in the remote controller 2. Specifically, the ID setting key 34 in the operation unit 21 of the remote controller 2 shown in FIG. 3 is operated. Next, the number key 35 to which “1” shown in FIG. At this time, the operation unit 21 outputs an operation signal So corresponding to the numeric key 35, and in response thereto, the control unit 22 based on the operation signal So has ID1 of the projector 1 to be operated as “1”. Identification data Dd <b> 1 indicating that there is a message is stored in the storage unit 23.

  Subsequently, the cursor key 37 is operated after operating the color tone change key 36 in the operation unit 21 of the remote controller 2. At this time, the control unit 22 outputs the operation signal So corresponding to the color tone change key 36 and the cursor key 37 output from the operation unit 21 and the identification data Dd1 stored in the storage unit 23 to the transmission / reception unit 24. The transmitter / receiver 24 transmits the infrared signal Si corresponding to the operation signal So and the identification data Dd1. On the other hand, in each projector 1a-1d, the transmission / reception part 15 receives the infrared signal Si, and outputs the operation signal So and the identification data Dd1. Next, the control unit 11 determines that the operation signal So is output in step 51 of the display control process 50 described above, and subsequently executes step 52. In this case, since the control signal Sc2 is not output, the control unit 11 executes the notification process 60 shown in FIG. 6 (step 54).

  In the notification process 60, the control unit 11 determines whether ID2 specified by the identification data Dd2 stored in the second storage unit 18 and ID1 specified by the identification data Dd1 transmitted from the remote controller 2 match. It is determined whether or not (step 61). In this case, since ID2 is set to “1” in projector 1a, control unit 11 determines that ID2 and ID1 (in this case ID1 = 1) match, and is output from operation unit 21. Processing corresponding to the operation signal So corresponding to the color tone change key 36 and the cursor key 37, that is, color tone adjustment processing for the projection unit 14 is executed (step 62). Thereby, the color tone of the image Gpa projected and displayed by the projector 1a is changed.

  Next, the control unit 11 reads the notification image data Di for the notification image Gi2 described above from the first storage unit 17 and outputs the notification image data Di to the image processing unit 13, and also controls the image processing unit 13 to control the notification image Gi2 described above. Is displayed on the image Gpa so as to be projected and displayed (step 63). Subsequently, the control unit 11 receives a control signal Sc corresponding to the notification display prohibition key 39 from the remote controller 2 (this control signal Sc corresponds to the third control signal in the present invention, hereinafter also referred to as “control signal Sc3”). It is determined whether or not it has already been output (step 64). In this case, since the control signal Sc3 is not output at this time, the control unit 11 causes the projection unit 14 to start displaying the notification image Gi2 (step 65). In response to this, the projection unit 14 projects the projection light L that is light-modulated based on the display data De. As a result, as shown in FIG. 8, the notification image Gi2 is projected and displayed on the screen 300 while being superimposed on the image Gpa by projection of the projection light L from the projector 1a. In this case, as shown in the figure, for example, the notification image Gi2 is configured such that the value of ID1 and the value of ID2 are described on a rectangular background that is white, semi-transparent (translucent).

  On the other hand, in the projector 1b, since ID2 is set to “2”, the control unit 11 determines that ID2 and ID1 do not match (mismatch) in the above-described step 61, and the first storage unit The above-mentioned notification image data Di for the notification image Gi1 is read from 17 and output to the image processing unit 13, and the image processing unit 13 is controlled to display the notification image Gi1 superimposed on the image Gpa. The business data De is output (step 66). Next, the control unit 11 determines whether or not the control signal Sc3 is output from the remote controller 2 together with the operation signal So (step 64). In this case, since the control signal Sc3 is not output at this time, the control unit 11 causes the projection unit 14 to start displaying the notification image Gi2 (step 65). In response to this, the projection unit 14 projects the projection light L that is light-modulated based on the display data De. As a result, as shown in FIG. 8, the notification image Gi1 is projected and displayed on the screen 300 so as to be superimposed on the image Gpb by projection of the projection light L from the projector 1b. Similarly, each control unit 11 in the projectors 1c and 1d sequentially executes Steps 66, 64, and 65. Thereby, as shown in the figure, the notification image Gi1 is projected and displayed on the screen 300 so as to be superimposed on the images Gpc and Gpd by projection of the projection light L from the projectors 1c and 1d. In this case, in the notification image Gi1, for example, as shown in the figure, the ID1 value, the ID2 value, and the message indicating that both ID1 and ID2 do not match are orange (a color different from the background of the notification image Gi2). It is described and structured on the background. That is, the notification image Gi1 and the notification image Gi2 described above are projected and displayed in different display colors.

  In this case, since the notification images Gi1 and Gi2 are projected and displayed by the projectors 1a to 1d, the user operates the projector 1 which is in the state where the ID1 and ID2 match or does not match or which of the projectors 1a to 1d. It is possible to confirm at a glance whether information is set as a target. For this reason, for example, when an operation on the desired projector 1 cannot be performed due to a setting error of ID1 and ID2, it is possible to surely prevent the inconvenience of giving the user a misunderstanding as to whether the cause is due to a failure. It has become.

  Next, for example, when changing only the white balance of the image Gpa projected and displayed by the projector 1a while keeping the white balance of the images Gpb to Gpd projected and displayed by the projectors 1b to 1d, the operation unit of the remote controller 2 is used. After the white balance change key 38 in FIG. 21 is operated, the cursor key 37 is operated. Here, it is confirmed that the setting states of ID1 of the remote controller 2 and ID2 of the projectors 1a to 1d are as intended (correct state) by the notification images Gi1 and Gi2 displayed at the time of the above-described color tone adjustment. In the white balance adjustment for the projector 1a, when the display of the notification images Gi1 and Gi2 is unnecessary, the notification display prohibition key 39 of the operation unit 21 is operated together with the operation of the white balance change key 38 and the cursor key 37. .

  At this time, the transmitter / receiver 24 of the remote controller 2 controls the operation signal So corresponding to the white balance change key 38 and the cursor key 37, the infrared signal Si corresponding to the identification data Dd1, and the control signal Sc3 corresponding to the notification display prohibition key 39. In each of the projectors 1a to 1d, the transmission / reception unit 15 receives the infrared signal Si and outputs the operation signal So and the identification data Dd1. Next, the control unit 11 determines that the operation signal So is output in step 51 of the display control process 50 described above, and subsequently determines that the control signal Sc2 is not output in step 52 and performs the notification process 60. Execute (step 54).

  In this case, in the notification process 60, the control unit 11 of the projector 1a determines that ID2 and ID1 match in step 61 described above, and then the white balance change key 38 and the cursor output from the operation unit 21. Processing corresponding to the operation signal So corresponding to the key 37, that is, white balance adjustment processing for the projection unit 14 is executed (step 62). As a result, the white balance of the image Gpa projected and displayed by the projector 1a is changed. On the other hand, in step 64 described above, the control unit 11 determines that the control signal Sc3 is output, and causes the projection unit 14 to stop (prohibit) display of the notification image Gi2 (step 67). Thereby, only the image Gpa is displayed on the screen 300 without displaying the notification image Gi2.

  Further, the control units 11 of the projectors 1b to 1d also determine that the control signal Sc3 is output in the above-described step 64, and cause the projection unit 14 to stop (prohibit) display of the notification image Gi1. (Step 67). Thereby, only the images Gpb to Gpd are displayed on each screen 300 without displaying the notification image Gi2.

  In this case, it is possible to arbitrarily stop (prohibit) the display of the notification images Gi1 and Gi2 by operating the notification display prohibition key 39. Therefore, as described above, display of the notification images Gi1 and Gi2 is not necessary when an operation (the above-described color tone adjustment or white balance adjustment operation) is repeatedly performed on one of the projectors 1a to 1d. In this case, by stopping the display of the notification images Gi1 and Gi2, it is possible to prevent the situation in which the notification images Gi1 and Gi2 are displayed every time the operation is performed and the image Gp is difficult to see.

  On the other hand, in the projector 1, for example, when ID1 on the remote controller 2 side and ID2 on the projector 1 side do not match, an operation for projecting and displaying an operation for adjusting ID1 to ID2 and an operation for adjusting ID2 to ID1 are displayed. Can be used (on the screen). Hereinafter, in order to facilitate understanding of the invention, an operation example in a state where only the projector 1a among the projectors 1a to 1d described above is turned on will be described. In this case, for example, when the ID2 of the projector 1a to be set to “1” is erroneously set to “5” during the ID2 setting operation on the projector 1 side, the above-described color tone adjustment is performed. When the notification image Gi1 indicating that ID1 is “1” and ID2 is “5” is projected and displayed, the setting screen display key 40 in the operation unit 21 of the remote controller 2 is operated.

  At this time, the control unit 11 of each projector 1a to 1d reads the change screen data Ds from the first storage unit 17 in accordance with the control signal Sc1 corresponding to the setting screen display key 40 output from the transmission / reception unit 15. Are output to the image processing unit 13, and the image processing unit 13 is controlled to output display data De for projecting and displaying the change screen Gs. In response to this, the projection unit 14 projects the projection light L that is light-modulated based on the display data De, whereby the change screen Gs is projected and displayed on the screen 300 as shown in FIG. Next, in accordance with the instruction of the message displayed on the change screen Gs, the operation key on the operation unit 21 of the selected remote controller 2 is operated. Specifically, when changing ID2 on the projector 1a side to match (match) ID1 on the remote control 2 side (selecting “Yes” in the change screen Gs), the “Enter” key of the operation unit 21 is used. When operating (see FIG. 3) and not changing (selecting “No” in the change screen Gs), the “Esc” key (see FIG. 3) of the operation unit 21 is operated.

  In this case, when the “Enter” key is operated, the control unit 11 changes the value of ID2 set to “5” to the value of ID1 set to the remote controller 2 (in this case, “1”). The identification data Dd2 indicating the ID2 is overwritten and stored in the second storage unit 18 by overwriting. Thereby, ID2 of the projector 1a is changed. In this case, since the ID 2 of the projector 1 can be changed from a remote position by operating the remote controller 2 using the change screen Gs without operating the operation unit 16 of the projector 1, sufficient convenience for the user is provided. It is possible to improve.

  In contrast to the above-described method of changing ID2 on the projector 1 side to match ID1 on the remote control 2 side, ID1 on the remote control 2 side is changed to match ID2 on the projector 1 side (in this case, ID1 is changed to ID1). It is also possible to adopt a configuration in which “1” is changed to “5”. In this configuration, the control unit 11 transmits identification data Dd2 indicating ID2 on the projector 1a side to the remote control 2 via the transmission / reception unit 15, and the control unit 22 of the remote control 2 is based on the identification data Dd2 received by the transmission / reception unit 24. The ID 1 value set to “1” is changed to the ID 2 value (“5” in this case) set on the projector 1 a side, and the identification data Dd 1 indicating the ID 1 is overwritten in the storage unit 23. To remember. Even in this configuration, it is possible to sufficiently improve convenience for the user. In this case, without using this function, the user can change the ID1 setting by operating the ID setting key 34 and the numeric key 35 of the remote controller 2 with reference to the notification image Gi1.

  Thus, according to the display control device, the projector 1, and the display control method, the control unit 11 notifies that the ID 1 that designates the projector 1 to be operated does not match the ID 2 that is set in the projector 1. By executing the notification process 60 for causing the projection unit 14 to project and display at least one of the notification image Gi2 that notifies that the images Gi1 and ID1 and ID2 match, the state where ID1 and ID2 match or does not match The user can confirm at a glance information such as which of the projectors 1a to 1d is set as the operation target. For this reason, for example, when an operation on the desired projector 1 cannot be performed due to a setting error of ID1 or ID2, it is possible to reliably prevent a user from having a misunderstanding that the cause is due to a failure. Further, by displaying the set ID1 and ID2 in the notification images Gi1 and Gi2, when there is an error in setting ID1 and ID2, the error can be easily corrected (changed). For this reason, the inconvenience of resetting the ID2 of all projectors 1 due to the difficulty of knowing the set ID1 and ID2 can be reliably solved.

  Further, according to the display control device and the projector 1, when the control signal Sc1 is transmitted, the control unit 11 projects in accordance with the operation signal So corresponding to the power key 31 regardless of the coincidence or disagreement of both ID1 and ID2. Unlike the general configuration in which processing for all operation signals So is not executed when ID1 and ID2 do not match by executing power supply processing for the unit 14, even if ID1 and ID2 do not match, It is possible to reliably supply power to the projection unit 14 and display the notification images Gi1 and Gi2 with certainty.

  Further, according to the display control device and the projector 1, when the control signal Sc2 is transmitted, the control unit 11 performs display processing on the projection unit 14 according to the operation signal So regardless of whether the both ID1 and ID2 match. When the control signal Sc2 is not transmitted, by causing the projection unit 14 to execute display processing according to the operation signal So only when both ID1 and ID2 match, for example, for all the projectors 1a to 1d A usage pattern that places importance on efficiency, such as performing predetermined operations all at once, and a usage pattern that places importance on security that restricts operations by others so that a predetermined operation can be performed only on a specific projector 1. It can be easily switched depending on whether or not to transmit the control signal Sc2. For this reason, it can respond to a user's usage form flexibly.

  Furthermore, according to the display control device and the projector 1, the control unit 11 stops displaying the notification images Gi1 and Gi2 when the control signal Sc3 is transmitted, so that the display of the notification images Gi1 and Gi2 is unnecessary. In some cases, the display of the notification images Gi1 and Gi2 can be arbitrarily stopped by simply transmitting the control signal Sc3. Therefore, when the projector 1 is repeatedly operated, the notification images Gi1 and Gi2 are displayed each time the operation is performed. The situation where the displayed image Gp is difficult to see can be reliably prevented.

  Further, according to the display control device and the projector 1, the control unit 11 causes the display color of the notification image Gi1 and the display color of the notification image Gi2 to be displayed differently, so that the display unit can be separated from the display position. Since the notification image Gi1 and the notification image Gi2 can be clearly distinguished and visually recognized, it is possible to reliably recognize whether or not ID1 and ID2 match.

  Further, according to the display control device and the projector 1, the operation unit 16 of the projector 1 is displayed by projecting and displaying the change screen Gs for changing at least one of ID1 and ID2 when ID1 and ID2 do not match. Since the change ID G2 of the projector 1 can be changed from a remote position by operating the remote controller 2 using the change screen Gs without operating, the convenience for the user can be sufficiently improved.

  In addition, this invention is not limited to said structure. For example, the example in which the notification process 60 is executed based on the identification data Dd1 transmitted from the remote controller 2 together with the operation signal So and the control signal Sc has been described above, but information that can be specified as an operation target (hereinafter referred to as “operation target”). It is also possible to adopt a configuration in which “information Do” (see FIG. 1) is stored in the second storage unit 18 of the projector 1 and the notification process 60 is executed based on the operation target information Do. In this configuration, for example, when one of the projectors 1a to 1d described above (for example, the projector 1a) is designated as an operation target, after operating the ID setting key 34 in the operation unit 21 of the remote controller 2, The numeric key 35 corresponding to ID2 of the projector 1a (in this example, the numeric key 35 to which “1” is attached) is operated. At this time, the control unit 11 of the projector 1 a generates the operation target information Do according to the operation signal So corresponding to the ID setting key 34 and the numeric key 35 and stores it in the second storage unit 18. In this case, the content of the operation target information Do may be data (numerical data) indicating that both ID1 and ID2 are “1”, or may be a flag indicating that the operation target information Do is an operation target. .

  In this configuration, when the operation signal So is transmitted and the identification data Dd1 is not transmitted together with the operation signal So, the control unit 11 performs the notification process 60 based on the operation target information Do stored in the second storage unit 18. Execute. Specifically, the control unit 11 of each projector 1a to 1d determines whether or not the operation target information Do is stored in the second storage unit 18 when the operation signal So is transmitted, and the operation target information is determined. When Do is stored, the same processing as when it is determined that ID1 and ID2 match is performed. On the other hand, when the operation target information Do is not stored in the second storage unit 18, the same processing is performed when it is determined that ID1 and ID2 do not match. According to this configuration, for example, the above-described notification images Gi1 and Gi2 can be displayed even when the remote controller 2 does not have a function of transmitting the identification data Dd1, that is, a function of setting ID1. Therefore, an effect similar to the above effect can be realized.

  Further, the example in which the projection display of the notification images Gi1 and Gi2 is stopped when the notification display prohibition key 39 is operated has been described above, but the projection display is automatically performed when a predetermined time has elapsed from the start of the display of the notification images Gi1 and Gi2. A configuration in which the control unit 11 controls the projection unit 14 so as to be stopped may be employed.

  Further, in the initial state, when the projection display of the notification images Gi1 and Gi2 is stopped, a key for instructing the display of the notification images Gi1 and Gi2 is provided on the remote controller 2, and the key is operated (in the present invention, It is also possible to employ a configuration in which the control unit 11 controls the projection unit 14 so that the notification images Gi1 and Gi2 are projected and displayed only when the fourth control signal is output and the notification processing permission state is set. Also in this configuration, when a predetermined operation is repeatedly performed on one of the plurality of projectors 1 using the remote controller 2, the notification image Gi1, Gi2 is displayed for each operation, whereby the image Gp is displayed. It is possible to prevent a situation that is hidden and difficult to see.

  In addition, as an example of a method for making display colors of the notification images Gi1 and Gi2 different from each other, the example of changing the background color has been described above. For example, the character color in the notification image Gi1 and the character color in the notification image Gi2 are changed. It can also be different from each other.

  In addition, the example in which the present invention is applied to the projector 1 including the projection unit 14 as a display unit has been described above, but instead of the projection unit 14, a display unit including a CRT, a liquid crystal display panel, and a plasma display is provided. It can be applied to the device. Further, the present invention can be applied to a display control device that does not include a display unit and that performs the above-described various processes on an external display unit.
