[0029]
That is, when the projector utility program is started in the computer 100, the CPU 102 functions as the control unit construction unit 120 as described above. First, the control unit construction unit 120 accesses the projector 200 from the network controller 116 via the network 300, and requests the transfer of the setting basic information 220 necessary for constructing the operation state control unit 122.
[0030]

[0031]
FIG. 2 is an explanatory diagram showing the contents of the setting basic information 220 stored in the memory 204 of the projector 200. The setting basic information 220 is information for defining a setting item and a setting method for each operation state when the computer 100 controls the operation state of the projector 200. As described above, since the setting items for the operation state of the projector differ depending on the model of the projector, the setting basic information 220 also differs for each model of the projector. That is, in each projector 200, setting basic information 220 for the model is prepared and stored.
[0032]
The setting basic information 220 is specifically composed of a parent item table and a sub-item table as shown in FIG. The setting items have a two-layer structure of a parent item and a sub-item as a whole, and a plurality of sub-items respectively belong to each parent item. In this embodiment, since there are six parent items as described later, six sub-item tables are prepared in addition to the parent item table. Although not shown in the figure, the number of sub-items included in the sub-item table is described in the header of each sub-item table.
[0033]
FIG. 3 is an explanatory diagram showing the contents of the parent item table in FIG. As shown in FIG. 3, the parent item table describes a parent item identification number parent_id and the contents of the parent item in association with each other. In the present embodiment, in order to control the operation state of the projector 200, “video”, “audio”, “advanced setting”, “network setting”, “information”, “all initial” Is prepared, and a parent item identification number parent_id is attached to each of them.
[0034]
FIG. 4 is an explanatory diagram showing the contents of the sub-item table 1 in FIG. As shown in FIG. 4, the subitem table describes eleven elements of id, parent_id, label1, ctl_id, ctl_param, label2, c_value, r_value1, r_value2, font, and color for each subitem. FIG. 4 shows the sub-item table 1 belonging to the parent item “video” among the six sub-item tables, but the other sub-item tables have substantially the same configuration.
[0035]
FIG. 5 is an explanatory diagram showing the type and contents of each element in the sub-item table of FIG. That is, among the eleven elements, as shown in FIG. 5, id is the identification number of the target sub-item, and parent_id is the identification number of the parent item to which the target sub-item belongs. Are also of the "int" type. Further, label1 is a character string described in the label area 1 for a target sub-item on a setting screen described later, and has a “string” type. ctl_id is an identification number indicating the type of a setting operation unit used when the user makes a setting for a target sub-item, and has an “int” type. ctl_param is an attribute value necessary for generating the setting operation means, and has a “string” type. label2 is a character string described in the label area 2 on the setting screen, and has a “string” type. c_value is a value currently set in the projector 200 for the target sub-item, and r_value1 is a value obtained from the setting operation means when the user sets the value using the setting operation means. R_value2 is a variable name used when the stored value is transmitted to the projector 200, and both are of the “string” type. font is a font for displaying the label, caption, and setting operation means, and color is a foreground color and a background color for displaying the label, caption, and setting operation means, all of which are “string” type. ing.
[0036]
In the computer 100, when the control unit constructing unit 120 receives such basic setting information 220 from the projector 200, the control basic unit 220 stores the basic setting information 220 in the memory 104.
[0037]
On the other hand, a setting operation unit definition table (not shown) that defines the contents of the setting operation unit is stored in the memory 104 of the computer 100 in advance.
[0038]
FIG. 6 is an explanatory diagram showing the contents of such a setting operation means definition table. As shown in FIG. 6, the setting operation unit definition table includes an identification number ctl_id indicating the type of the setting operation unit, the contents of the setting operation unit, the parameters used when generating the setting operation unit, and the parameters. The contents of and are defined. Among them, the setting operation unit identification number ctl_id corresponds to that in the sub-item table shown in FIG.
[0039]
FIG. 7 is an explanatory diagram showing an example of a setting screen generated based on the setting basic information 220. In FIG. 7, an area A is an area in which a list of parent items is displayed, and an area B is an area in which, for a selected parent item, a list of sub-items belonging to the parent item is displayed.
[0040]
Subsequently, the control unit construction unit 120 uses the setting basic information 220 stored in the memory 104 and a setting operation unit definition table prepared in advance to display the setting screen shown in FIG. 7 in a graphical user interface (GUI). The operation state control unit 122 provided as the above is constructed.
[0041]
That is, the control unit construction unit 120 first reads the parent item table shown in FIG. 2 from the stored basic setting information 220, and, based on the parent item table, displays the area A in the setting screen shown in FIG. Generate the part of. Specifically, the content of the parent item is sequentially acquired from the parent item table shown in FIG. 3, and the setting button using the content as a label is sequentially generated.
[0042]
When the operation state of the projector 200 is controlled on this setting screen, when the user selects any of these setting buttons, a list of sub-items belonging to the selected parent item is displayed in the area B. It has become so. Therefore, when the selection of the setting button of the parent item is switched, the display of the area B is also switched accordingly.
[0043]
Next, the control unit construction unit 120 reads out the sub-item table 1 shown in FIG. 2 from the stored basic setting information 220 and, when the parent item “video” is selected based on the sub-item table 1, , The contents to be displayed in the area B are generated. It should be noted that the parent item and the sub-item table are related by the identification number parent_id of the parent item in the sub-item table.
[0044]
Specifically, first, the control unit construction unit 120 reads the number of sub-items included in the sub-item table 1 from the header of the sub-item table 1, and stores the value in a counter (FIG. (Not shown). That is, this number is the number of sub-items belonging to the parent item “video”. Further, the control unit construction unit 120 sets the creation target line at the uppermost position in the area B.
[0045]
Next, the control unit construction unit 120 acquires a row having the sub-item identification number id of “1” from the sub-item table 1 shown in FIG. 4, and based on the content, obtains a) to e) described later. Perform processing. Thereafter, it is determined whether or not the counter value has become 0. If the counter value has not become 0, a row with the sub-item identification number id of “2” is obtained from the sub-item table 1 and based on the content thereof, , The same processing as a) to g) is performed. Then, it is determined whether or not the counter value has become 0. If the counter value has not become 0, the rows are sequentially acquired from the sub-item table 1 in the same manner as described above, and the process is repeated until the counter value becomes 0. .
[0046]
Next, the processes a) to g) performed when a certain row is acquired from the sub-item table 1 will be described.
[0047]
a) The character string of label1 is described in the label area 1, and the character string of label2 is described in the label area 2.
[0048]
b) On the basis of the value of ctl_id, the content of the corresponding setting operation means is acquired from the setting operation means definition table, and the value of ctl_param is set as the value of the parameter of the corresponding setting operation means. Then, a setting operation unit having the acquired content is generated by reflecting the set parameter value.
[0049]
c) The value of c_value is set as an initial value of the generated setting operation means.
[0050]
d) The value of r_value1 is set as the type of a variable when storing the value acquired from the generated setting operation means.
[0051]
e) The value of r_value2 is obtained from the generated setting operation means and stored, and is set as a variable name for returning to the projector 200.
[0052]
f) Based on the value of the font, the font of the label, the caption, and the setting operation means are set, and based on the value of the color, the foreground color and the background color thereof are set. If no value is provided for font and color, the control unit construction unit 120 sets the font, foreground color, and background color based on default values prepared in advance.
[0053]
g) Move the setting target line to the next lower line, and decrement the counter by one.
[0054]
More specifically, for example, a case will be described in which a sub-item identification number id “8” is acquired from the sub-item table 1 shown in FIG.
[0055]
First, in the process of a), the character string of label1 is "automatic setup", so this character string is described in the label area 1 in the line to be created, and the character string of label2 is blank. , Label area 2 is blank.
[0056]
Next, in the process b), since the value of ctl_id is “3”, “radio button” is acquired as the corresponding setting operation means from the setting operation means definition table shown in FIG. Since the value of ctl_param is “ON, OFF”, “ON” is set as the caption name string “caption1” which is a parameter of the “radio button”, and “OFF” is set as the caption name string “caption2”. Then, based on these, two radio buttons with captions “ON” and “OFF” are generated in the creation target line.
[0057]
Next, in the process of c), since the value of c_value is “ON”, this “ON” is set as the initial value of the radio button. That is, the radio button of the caption “ON” is selected.
[0058]
Subsequently, in the process d), since the value of r_value1 is “String”, when the user sets using the radio button, the type of the variable used to store the value obtained from this radio button is , “String”.
[0059]
In the process e), since the value of r_value2 is “r_strAutoSet”, the variable name used when returning the value acquired from the radio button and stored to the projector 200 is set to “r_strAutoSet”.
[0060]
Further, in the process f), the font value is "Mincho", so that the font of the label, caption, and setting operation means is set to Mincho in the line to be created. In addition, since the value of color is “black, white”, the foreground color in the creation target row is set to black, and the background color is set to white.
[0061]
Finally, in the processing of g), the line to be set is moved to the next lower line, and the counter is decremented by one.
[0062]
As described above, the processes of a) to g) are repeated, and when the value of the counter finally becomes 0, the process for the sub-item table 1 ends.
[0063]
As a result, the content to be displayed in the area B when the parent item “video” is selected is generated as shown in FIG.
[0064]
Next, the control unit construction unit 120 reads out the sub-item table 2 shown in FIG. 2 from the stored basic setting information 220 and, when the parent item “voice” is selected based on the sub-item table 2, The content to be displayed in the area B is generated.
[0065]
In a similar manner, the sub-item table is sequentially read out, and when the generation of the contents to be displayed in the area B when all the parent items are selected is completed, the processing by the control unit construction unit 120 is performed. All ends.
[0066]
As described above, the operation state control unit 122 having the setting screen as shown in FIG. 7 as the GUI is constructed by the control unit construction unit 120. That is, the control unit construction unit 120 receives the provision of the setting basic information 220 prepared for the projector 200 from the projector 200 connected to the computer 100, and controls the operation state of the projector 200. The construction unit 120 can be constructed.
[0067]
D. Controlling the operating state of the projector:
Thus, once the operation state control unit 122 is constructed, the control unit construction unit 120 does not operate thereafter. That is, thereafter, when the projector utility program is started in the computer 100, the CPU 102 functions as the operation state control unit 122.
[0068]
Therefore, when the user activates the projector utility program to control the operation state of the projector 200 using the computer 100, the operation state control unit 122 first displays the setting screen shown in FIG.
[0069]
Therefore, the user attempts to control, for example, an operation state relating to a video among the operation states of the projector 200 by using the input device 106 to display a parent item list in the area A of the setting screen on which the parent item list is displayed. When the “video” setting button is selected, the operation state control unit 122 detects that, switches the display of the area B, and displays the sub-item belonging to the parent item “video” as shown in FIG. Display the list.
[0070]
Further, the user uses the input device 106 to control the sharpness among the operation states related to the video, and in the area B where the list of the sub-items is displayed, the setting operation means of the sub-item “sharpness”, that is, the slider When a plus button or a minus button of the control is pressed, the operation state control unit 122 detects which button is pressed and also detects the number of times or the time when the button is pressed. Then, based on the detection result, the operation state control unit 122 calculates a control value corresponding to the detection result from the eleven stages of “−5 to +5”, and assigns the control value to the sub-item “sharpness Is obtained from the setting operation means (ie, slider control).
[0071]
The operation state control unit 122 refers to the type of the variable set for the slider control of the sub-item “sharpness” (that is, the type of the variable previously set based on the value of r_value1), and obtains the obtained control value. Is stored in the memory 104 in the set variable type “int”. Further, the operation state control unit 122 reads out the stored control value, and refers to the variable name set for the slider control (that is, the variable name previously set based on the value of r_value2), The variable name “r_nSharpness” and the control value are paired and transmitted from the network controller 116 to the projector 200 via the network 300.
[0072]
In projector 200, when CPU 102 receives the transmitted pair of the variable name and the control value from network controller 214, CPU 102 recognizes from the variable name “r_nSharpness” that the control value is a control value of sharpness. Then, the image processing circuit 206 and the image projection unit 208 are controlled according to the control value to change the sharpness of the projector 200 from the current value. In this way, among the operation states related to the video, the sharpness is controlled by the operation state control unit 122.
[0073]
Similarly, when the user controls other setting items among the operation states related to the video, the user operates the setting operation unit of the corresponding sub-item in the area B, and the operation state control unit 122 performs the setting operation. The control value is obtained from the means and transmitted to the projector 200. In the projector 200, the control is performed by the CPU 102 controlling the image processing circuit 206 and the image projection unit 208 based on the control value.
[0074]
In the above description, the case where the user has selected “video” as the parent item has been described. However, when the user selects another parent item such as “audio”, the display in the area B is similarly By switching and displaying a list of sub-items belonging to the parent item, the operation state can be controlled in the same manner.
[0075]
E. FIG. Effects of the embodiment:
As described above, in the present embodiment, in the computer 100, by activating the projector utility program, the control unit construction unit 120 functions to acquire the setting basic information from the projector 200, and The operation state control unit 122 is constructed based on Therefore, even if the projector utility program is software that does not depend on the model of the projector, if the setting basic information corresponding to the model of the projector 200 is stored in the projector 200, the control unit is controlled based on the setting basic information. Since the construction unit 120 constructs a dedicated operation state control unit 122 corresponding to the model of the projector 200, the operation state control unit 122 thereafter functions to operate the operation state corresponding to the model of the projector 200. Can be controlled.
[0076]
Therefore, according to the present embodiment, in order to control the operation state of the projector, it is not necessary to prepare dedicated software for each model of the projector as software to be executed by the computer 100, and the Web server function is required for the projector. do not do.
[0077]
Depending on the type of projector, there may be many setting items, and conversely, there may be few setting items. Therefore, it is necessary to prepare the basic setting information to be stored in the projector in accordance with the number and contents of the setting items.
[0078]
For example, in order to control the operation state of a certain projector model, it is necessary to add a new sub-item to the sub-item belonging to the parent item “video” shown in FIG. May be prepared in the sub-item table 1 shown in (1), setting basic information in which a row corresponding to the new sub-item is added. Conversely, if it is necessary to reduce unnecessary sub-items, the sub-item table 1 What is necessary is just to prepare the setting basic information from which the line corresponding to the unnecessary sub-item is deleted.
[0079]
Also, when it is necessary to add a new parent item to the parent item shown in FIG. 7 in order to control the operation state, the new parent item row is added to the parent item table shown in FIG. In addition to adding it, it is sufficient to prepare setting basic information that newly added a table of sub-items that should belong to the parent item. Conversely, if it is necessary to reduce unnecessary parent items, from the parent item table, What is necessary is just to delete the unnecessary parent item row and prepare the setting basic information from which the sub-item table belonging to the parent item has been deleted.
[0080]
By the way, when a projector of a different model from the previous model is newly connected to the computer 100 and the operation state of the projector is to be controlled by the computer 100, the computer 100 starts up the projector utility program. Even if the operation state control unit corresponding to the previous model has already been constructed, the control unit construction unit 120 operates again, acquires the setting basic information from the new projector, and based on the setting basic information. Then, an operation state control unit corresponding to the model of the projector is constructed.
[0081]
Therefore, it is possible to support a new projector model without changing the projector utility program.
