Description

  The present invention relates to an OSD (On Screen Display) function of a projector in multi-projection for displaying using a plurality of projectors.

  One of the use cases of projectors is a multi-projection technology in which a plurality of projectors are connected and their projection planes are adjacent to each other to project one huge screen. An embodiment will be described with reference to FIG.

  FIG. 1 is a system block diagram and a projection image showing a projection system according to an embodiment of the present invention.

  Reference numerals 101 to 109 in FIG. 1 denote projectors capable of projecting the received data. The respective projectors are connected by a network 100. The data (image or video) received via the network 100 can be divided and displayed on the projectors 101 to 109.

  An example image of the displayed result is 110. The "Projector 1" field is the screen projected by the projector 101, and similarly, the "Projector 2" field is the screen projected by the projector 102, and the "Projector 3" field is the screen projected by the projector 103. In addition, the projector 109 is a screen image displayed in the “projector 9” column. In this embodiment, nine projectors are arranged in 3 × 3 and projected.

  For example, when projecting on a screen as shown in 110 in FIG. 1, since projection is performed using a plurality of projector housings, the brightness and color of the projection surface may be slightly changed depending on the difference in usage history of each housing. There may be differences. Even if the settings (parameter values) are the same on the numerical values set on the setting screen due to differences in usage history or differences in the amount of light at the projection location, the color shades differ from projector to projector, and they look different from expected Sometimes.

  In this case, parameters such as brightness and tint of a specific projector are changed, but when changing the settings (parameter values) of those projectors, various parameters of the projection plane are usually manipulated by operating the parameter values from the target projector. It is common to be able to make adjustments. That is, in order to change the parameter value of the projection plane of “projector 1”, the projector 101 itself is operated to set the parameter value, and to change the parameter value of the projection plane of “projector 9”, the projector 109 itself It is usually necessary to set the parameter value by manipulating.

  In the case of the above method, the user has to go back and forth between a plurality of projectors, open each setting screen, change the brightness, the color and the like, and the movement and operation of the user are troublesome.

  As a technology for solving this problem, there is an invention described in Patent Document 1.

  In Patent Document 1, the technology of a multi-display device is capable of operating another video display device from a video display device located at a position where the user can easily operate the video setting operation of each video display device in multi-display display. It is disclosed.

JP, 2011-257524, A

  However, Patent Document 1 can change parameter values from the projector located at a position easy for the user to operate according to the setting screen (OSD function) of another projector, but selects the projector to be operated. Since it is necessary to perform the operation after displaying the setting screen for the selected projector, the setting of each projector is required even if only the parameter in the predetermined direction such as the projection plane near the ceiling or the projection plane near the window is changed. It has to be changed and it is a bothersome task. For example, if you want to increase the brightness and color depth of the projection surface, for example, if the projector is close to a window, you have to list the brightness and color depth of the three projectors, for example, in the case of 3 × 3 multi-projection .

  SUMMARY OF THE INVENTION It is an object of the present invention to easily set parameter operations of a plurality of projectors by enabling various settings of the projector to be set collectively in a projector configuring multi-projection.

  The configuration of FIG. 2 is an example, and it goes without saying that there are various configuration examples depending on the application and purpose. As another configuration example, it is also possible for the projector to generate a program by receiving a program generation instruction from an information processing apparatus such as a personal computer (not shown) that is connected to a network and can communicate.

  That is, the present invention can be applied to a system in which processing is performed via a network, whether it is a single device or a system including a plurality of devices as long as the functions of the present invention are realized. It can apply. This is the end of the description of the hardware configuration diagram of FIG.

  Next, with reference to FIG. 3, an image of the operation panel of the remote controller for giving an instruction to the projector shown in FIG. 2 will be described.

  FIG. 3 is an example of a remote control having an operation panel on which the projector in the embodiment of the present invention is operated.

  Reference numeral 301 in FIG. 3 denotes an example of a user interface panel of the remote controller, and reference numeral 302 denotes a [power] button for switching the projector on / off. [Analog] button 303 and [digital] button 304 are buttons for switching whether the input terminal to the projector is an analog RGB terminal (VGA terminal) or a digital terminal (for example, DVI terminal) input. There is also a method of acquiring projection information from a LAN and a method of acquiring projection information using an HDMI terminal. Reference numeral 305 denotes a cursor key used when operating the cursor of the OSD menu in the OSD menu screen in the present invention.

  Next, with reference to FIG. 4, an example of a database possessed by a master projector that operates the present invention will be described.

  FIG. 4 is an example of a data configuration diagram showing a database 400 possessed by the master projector of the projection system in the embodiment of the present invention.

  The data 400 in FIG. 4 has the following configuration. They are the ID 401 of the projector, the role 402 of each projector, the IP address 403 of each projector, and other parameter groups 404 set in the present invention. The role of the projector 402 includes a master projector and a slave projector, and the master projector plays a central role in multi-projection processing. For example, there is also a configuration in which the master projector first receives the information transmitted from the information processing terminal or the like and distributes the information to slave projectors other than the master projector. Further, the master projector may control only the OSD menu screen of the present invention. An IP address 403 is an address for accessing each projector, and a different value is set for each projector. The parameter group 404 is an example of parameters set according to the present invention, and there are, for example, “contrast”, “brightness”, “darkness of color”, etc., and there may be a plurality of other items to be set.

  In this embodiment, it is assumed that the projector 101 whose ID 401 is PJ1 is set as a master projector and the other projectors 102 to 109 are set as slave projectors. The description of the database 400 possessed by the master projector of FIG. 4 is ended.

  Next, with reference to FIG. 5 to FIG. 8, a process of displaying the OSD menu screen of the projection system configuring the multi-projection in the embodiment of the present invention and reflecting the set parameters will be described.

  FIG. 5 is a flowchart showing a process flow of generating a database 400 operating on the master projector of the projection system according to an embodiment of the present invention. The flowchart in FIG. 5 is executed by the CPU 201 of the projector 101 which is a master projector, and S501 to S504 in the figure indicate respective processing steps.

  The process of FIG. 5 is a flowchart started when, for example, the projector 101 is designated as a master projector by a predetermined operation in the remote controller 301.

  First, in step S501 in FIG. 5, the CPU 201 of the projector 101 acquires the number of connected projectors and the IP address 402. When acquiring the number of projectors and the IP address, the user may receive the input of the IP address 403 from the remote controller by the ten key 306 of the remote controller 301, or the input of the projector ID 401 may be accepted to specify the IP address 403. good. Further, projectors in the same segment on the network may be acquired to acquire the number of projectors connected and the like, and information may be acquired by any method.

  Next, in step S502, the CPU 201 of the projector 101 checks whether there is one among the projectors acquired in step S501 that has not acquired the projector's current setting value 404 or later. If there is an unacquired setting value 404 or later (Yes in step S502), the process transitions to step S503, and if there is no unacquired setting value 404 or later (No in step S502), the flowchart of FIG. Finish. At first, since it should not have information of all the projectors, the processing shifts to step S503.

  When the process proceeds to step S 503, the CPU 201 of the projector 101 transmits data of the current projector setting values (for example, the setting values 404 and the like of contrast, luminance, and color density) of the communicatable projector (for example, the projector 102). Are stored in the database 400 in the next step S504.

  After the setting values are stored in the database 400, the process returns to step S502 to acquire the current setting values of the next projector (for example, the projector 103). This process is repeated, and in the example of FIG. 1, it is repeated until the setting values of the slave projectors 102 to 109 are acquired. Then, it changes to No by the process of step S502, and ends the process of the flowchart of FIG. This is the end of the description of the flowchart of FIG.

  Next, the process of reflecting the set parameters by displaying the OSD menu screen in the projection system according to the embodiment of the present invention will be described with reference to the flowchart of FIG.

  FIG. 6 is a flowchart showing a process flow of changing the setting value (parameter value) in each projector of the projection system in the embodiment of the present invention and reflecting the change. The flowchart in FIG. 6 is executed by the CPU 201 of the projector 101 which is the master projector or the CPU 201 of the slave projectors 102 to 109, and S601 to S612 in the figure indicate the respective processing steps.

  The process in FIG. 6 is a flowchart that is started, for example, when the user tries to display the OSD menu screen of the master projection by a predetermined operation of the remote controller 301 in the projector 101 which is the master projector. It is assumed that each projector projects a test image or the like on the screen before the operation of the flowchart in FIG.

  First, in step S601 in FIG. 6, the CPU 201 of the projector 101 acquires and stores the current setting value of the projector to be operated from the database 400.

  Next, in step S602, the CPU 201 of the projector 101 receives the change of the setting value of each projector by the user. The method of accepting the setting value of the user by each projector will be described later with reference to FIGS. 7 and 8.

  Next, in step S603, the CPU 201 of the projector 101 notifies the projector of the changed setting value of the changed setting value.

  The CPUs 201 of the projectors 102 to 109 which are slave projectors having received the notified setting value reflect the notified setting value and project it on the screen.

  Next, in step S604, the CPU 201 of the projector 101 receives a result of determination as to whether or not the change operation of the setting value is completed from the user. If the user subsequently receives an input to change the setting value (No in step S604), the process returns to step S602, and the change of the setting value of each projector by the user is received again. On the other hand, if the user does not input the setting value of the projector, or accepts the determination that the change of the setting value is completed (for example, pressing the [OK] button at the center of the cursor key 305), the next step is performed. The process transitions to S605.

  In step S605, the CPU 201 of the projector 101 determines whether the enter key (“decision” button displayed on the confirmation screen not shown) is pressed by the user's operation or the cancel key (“cancel” button displayed on the confirmation screen not shown) It is judged whether) was pressed. When the determination key is pressed (Yes in step S605), the slave projectors 102 to 109 reflecting the changed setting value remain as they are, and the processing of the present invention ends. By this process, the user can change and project the setting values of a plurality of projectors.

  On the other hand, when the cancel key is pressed in step S605 (No in step S605), it is determined that the original set value is better than the changed set value, and the changed set value is restored. Then, the process transitions to step S606.

  When the process proceeds to step S606, the CPU 201 of the projector 101 notifies the slave projectors 102 to 109 whose operation target is the setting value acquired and stored in step S601.

  The CPUs 201 of the slave projectors 102 to 109 that have received the notified setting value reflect the notified setting value and project it on the screen, and the processing of the present invention is completed.

  Next, the process of accepting the change of the setting value of the parameter by the user in step S602 will be described with reference to FIG. 7 and FIG.

First Embodiment
FIG. 7 is a first flowchart showing a process flow of displaying an OSD menu screen operated by the master projector of the projection system according to the embodiment of the present invention and receiving setting values from the user. Note that the flowchart in FIG. 7 is executed by the CPU 201 of the projector 101 as a master projector, and S701 to 705 in the figure indicate the respective processing steps.

  The process of FIG. 7 is a flowchart of the first embodiment started when the process is shifted to step S602 of FIG. 6, and a parameter setting screen is displayed, and an input from the user is received on the parameter setting screen. , It is the process which receives the change value of a parameter.

  First, in step S701, the CPU 201 of the projector 101 acquires data of the database 400 stored in step S601. Further, the acquired database 400 is classified for each parameter. For example, if the contrast is 404, only the contrast column of each projector is classified and extracted, and if the luminance is luminance, only the luminance of each projector is classified and extracted.

  Next, in step S702, the CPU 201 of the projector 101 displays a parameter setting screen. The screen image to be displayed will be described with reference to FIG.

  FIG. 9 is an example of a first image diagram showing an example of the OSD menu screen of the projection system in the embodiment of the present invention.

  The projection view (screen) 900 of FIG. 9 is displayed so that each parameter is switched by the tab (901 to 905). The values of the respective projectors of the respective parameters are displayed in a list form at 905 to 914. For example, in the diagram 900, the brightness tab 902 (corresponding to the brightness) is projected, and changing the numerical value of each row changes the brightness (brightness) of each projector to the changed value. Become. Note that the projection view 900 is projected by the projector 101. That is, since the display is not performed on a plurality of projectors, the user can set parameters by looking at only one projection plane (the “projector 1” column in FIG. 1). The user has an advantage of being able to perform brightness adjustment and color density adjustment based on test images projected on a plurality of projection planes while adjusting parameters on the projection plane of the projector 101.

  Next, in step S703, the CPU 201 of the projector 101 receives an item of a tab for parameter adjustment from the user. The processes of steps S703 to S705 will be described with reference to the image diagram of FIG. 9 and the remote controller of FIG.

  In a state where the OSD menu screen 900 of FIG. 9 is projected on the screen, the user operates the remote controller 301 of FIG. 3 or the like.

  For example, when 900 is projected and the left and right keys of the cursor key 305 of the remote controller 301 are operated, the cursor on the projection plane moves back and forth between 901 and 905 (processing for accepting parameters to be adjusted in step S703). In the screen image of 900, the "brightness" adjustment parameter of 902 is selected.

  Next, when the upper and lower keys of the cursor key 305 are operated, the processing shifts to processing for selecting a projector for setting a parameter (processing for selecting a projector to be adjusted in step S704). In the screen image 900, the cursor is moved to the position 909 by pressing the cursor key 305 up and down several times. That is, it is specified to change the parameter setting of “brightness” for “projector 4”.

  Next, when the left and right keys of the cursor key 305 are operated in a state where the cursor of the OSD menu screen 900 is at 909, in the example of 900, the "brightness" setting value of "projector 4" can be changed Yes (parameter change acceptance process in step S705). For example, when the cursor is at 909 at 900, pressing the right side of the cursor key 305 changes the "brightness" of the "projector 4" from "+3" to "+4".

  By the above process, the process of changing the parameters of the individual projectors in the flowchart of FIG. 7 is ended, and the process returns to the flowchart of FIG. In the next step S603, the CPU 201 of the projector 101 transmits the changed setting value of the parameter to the slave projector. The slave projector (the instruction to the projector 4 in the case of the example 900, the projector 104) changes the parameter and projects a test image or the like with the changed setting value of the parameter on the projection plane. The brightness of the projection plane of the projector 4 displayed under the projector 1 of the projection plane 110 of FIG. 1 will be described with reference to the examples of the projection planes 900 of FIG. 9 and FIG. Change to the set value and project.

  As described above, parameters of a plurality of projectors can be changed from a parameter setting screen (OSD menu screen) projected to one projector, and setting values of individual projector parameters are displayed in comparison with a plurality of projectors, By being able to immediately reflect the changed setting value, it becomes possible to easily change the setting value of the parameter without switching to the setting screen of each projector as in Patent Document 1.

  The column 915 in FIG. 9 is a setting screen that is effective when changing the parameter as a whole. In this setting, the overall parameter is changed relative to the difference between the parameters 905 and 914 as it is. For example, when the cursor is moved to 915 and moved one step in the positive direction at the stage of 900, the brightness of the projector 1 changes from "+0" to "+1", and the brightness of the projector 2 changes from "-1" to "+1". The projector 3 changes the setting value from “+1” to “+2” in the same manner as “0”. By this processing, even if there is a difference in brightness due to a difference in the use history for each case, etc., after adjusting the brightness once, the difference in the case is absorbed to some extent even when changing the overall brightness Thus, it becomes possible to adjust the brightness and the like, and to prevent variations in the brightness of the projection surface.

Second Embodiment
FIG. 8 is a second flowchart showing the flow of processing for displaying an OSD menu screen operated by the master projector of the projection system according to the embodiment of the present invention and receiving setting values from the user. The flowchart in FIG. 8 is executed by the CPU 201 of the projector 101 which is the master projector, and S801 to S808 in the figure indicate the respective processing steps.

  The process of FIG. 8 is a flowchart of the second embodiment started when the process is shifted to step S602 of FIG. 6, and the parameter setting screen (OSD menu screen) is displayed, and the user sets the parameter setting screen. It is the process which receives the input from and receives the change value of a parameter.

  Before the process of FIG. 8, first, the CPU 201 of the master projector acquires parameters 404 and after from 401 of the database 400 of FIG. 4. That is, the same process as step S701 is performed. In addition, in the flowchart of FIG. 8, information up to the projection position 405 of the projector is also acquired. The projection position 405 of the projector is data in which the position to be projected in multi-projection is designated by (horizontal and vertical) coordinates. The example of 400 is set based on the data of 110 of FIG.

  First, in step S801, the CPU 201 of the projector 101 displays an arrangement image in which the respective projectors are arranged on the projection surface of the projector 101 which is the master projector. This arrangement data uses projector position information 405 acquired in advance. The screen image to be displayed will be described with reference to FIG.

  FIG. 10 is an example of a second image diagram showing an example of the OSD menu screen of the projection system in the embodiment of the present invention.

  The projection screen 1000 in FIG. 10 is projected only on the projection surface of the projector 101 which is the master projector, and each parameter is displayed so as to be switched by the tabs (1001 to 1005). In the tab column of each parameter, set values 1006 of the parameter selected on the tab are projected as a matrix at the projection position of each projector. The processing after step S802 will be described with reference to the image diagram of FIG.

  After displaying the setting values of the parameters selected on the tab of each projector as a matrix such as 1006 as shown in 1000 of FIG. 10, in order to display the parameter change of 1007 to 1023, the following steps S802 to S806 Execute the process

  In step S802, the CPU 201 of the projector 101 determines whether or not there are two or more rows of projection positions of the projector. If there are two or more columns, that is, if there are two or more types of "vertical" of the projected position of the projection position 405 of the projector, the process transitions to step S803, and there is only one column. , And the process transitions to step S804.

  When the process proceeds to step S 803, the CPU 201 of the projector 101 executes a process of displaying (projecting) items for collectively setting parameters for each row. Item display for collectively setting parameters for each row will be described with reference to FIG.

  In 1000 of FIG. 10, items 1007, 1008, and 1009 are items for collectively setting parameters for each row. For example, assuming that “specific row” is selected in step S 807 described later, moving the cursor to 1007 means changing the projector parameters at the designated position as in 1010. The process of step S 807 will be described later. When the process of step S803 ends, the process transitions to the process of step S804.

  Next, in step 804, the CPU 201 of the projector 101 determines whether the projection position of the projector is two or more lines. If there are two or more lines, that is, if there are two or more types of "horizontal" of the projected position of the projection position 405 of the projector, the process proceeds to step S805, and if there is only one line. , And the process proceeds to step S806.

  When the process proceeds to step S805, the CPU 201 of the projector 101 executes a process of displaying (projecting) items for collectively setting parameters for each column. Item display for collectively setting parameters for each column will be described with reference to FIG.

  In 1020 of FIG. 10, items 1021, 1022, 1023 are items for collectively setting parameters for each column. For example, assuming that “specific column” is selected in step S 807 described later, moving the cursor to 1021 means changing the projector parameters at the designated position as in 1024. The process of step S 807 will be described later. When the process of step S805 ends, the process proceeds to step S806.

  When displaying (projecting) 1007, 1008, 1009, 1021, 1022, 1023 which are batch setting items for each row or column in step S803 or step S805, next, in step S806, the CPU 201 of the projector 101 Executes processing to display (project) items for collectively changing the parameters of the projection plane. Item display for collectively setting parameters of all projection planes will be described with reference to FIG.

  In 1000 of FIG. 10, 1011 is an item for collectively setting parameters of all projection planes. For example, when “all projection plane” is selected in step S 807 described later, this means that the parameters designated by the tabs 1002 of all the projectors on the projection plane are relatively changed.

  Next, in step S 807, the CPU 201 of the projector 101 causes the user to change the parameters of the “specific row”, the parameters of the “specific column”, or the parameters of the “all projection planes”, Or accept the parameter of "individual projection plane".

  The processing after this selection acceptance method will be described with reference to the image diagram of FIG. 10 and the remote controller of FIG.

  In step S 807, when the image diagram of FIG. 10 is displayed, first, specification is accepted in the tab of the parameter to be adjusted by the left and right operation of the cursor key 305 of the remote controller 301 as in the first embodiment. In the case of 1000, a parameter of "brightness" is set as in 1002.

  Next, the cursor is moved on the OSD menu screen by the up and down operations of the cursor key 305. The order of movement is arbitrary. For example, when the down key is pressed first, 1007 becomes active (the cursor moves), and when the down key is pressed next, 1008 and 1009 are moved, and the next down key is pressed Then, the cursor is moved to 1021, next 1022, next 1023, and so on. When 1011 is activated by pressing the next down key and then the down key is pressed, only the projector 1 may be activated, and when activating the next down key, only the projector 2 may be activated. . In this example, when the down key is pressed, the batch setting for each row is selected first, then the batch setting for each column is selected, then all projection planes are selected, and finally each projector is selected It is an example.

  In the next step S808, the CPU 201 of the projector 101 performs a process of changing the setting value of the parameter of the selected projector as instructed by the user. The process of step S808 will be described with reference to FIG.

  In the OSD menu screen 1000 of FIG. 10, the cursor is at 1007. When the left and right keys of the cursor key 305 are operated in this state, in the example of 1000, “projector 1”, “projector 2”, “projector 3” The “brightness” setting value of “can be changed (parameter change acceptance process in step S 808). For example, with the cursor on 1007 of the OSD menu screen 1000, when the right key of the cursor key 305 is pressed once, the "brightness" of "Projector 1" changes from "+0" to "+1", "Projector 2" The “brightness” of “1” is changed from “−1” to “+0”, and the “brightness” of “projector 3” is changed from “+1” to “+2”.

  Similarly, in the OSD menu screen 1020 of FIG. 10, when the cursor is at 1021, when the left and right keys of the cursor key 305 are operated in this state, in the example of 1020, “projector 1”, “projector 4”, The set value of "brightness" of "projector 7" can be changed. For example, with the cursor on 1021 of the OSD menu screen 1020, when the right key of the cursor key 305 is pressed once, the "brightness" of "Projector 1" changes from "+0" to "+1" and "Projector 4" The "brightness" of is changed from "+3" to "+4", and the "brightness" of "projector 3" is changed from "-3" to "-2".

  With the above process, the process of changing individual projector parameters in the flowchart of FIG. 8 is ended, and the process returns to the flowchart of FIG. In the next step S603, the CPU 201 of the projector 101 transmits the changed setting value of the parameter to the slave projector. The slave projector (in the example of 1000, this is an instruction to projectors 1, 2, and 3 in the example of 1000, so the projector 101 (that is, itself), the projector 102, the projector 103) changes the parameters and changes to the projection plane Project a test image etc. with the set values of the specified parameters.

  As described above, the parameter setting screen (OSD menu screen) projected on one projector can easily reflect the parameter of the predetermined area and can immediately reflect the changed setting value, thereby increasing only the luminance of the predetermined area. It is easy to darken the color. For example, in the case of 3 × 3 multi-projection, only the vicinity of the ceiling is bright, so the upper three luminances and color depths are increased, and when the window is filled with light, the same color depth makes it difficult to see, etc. In addition, it is possible to easily make the color depth darker only at the window (for example, on the right side only).
