Next, display data 3, display data 2, and display data 1. In the display processing of the display data, the display order of the display data is determined based on this display order data. In this display process, for a portion (pixel) where a plurality of display data overlap, the color of the display data having a high priority is preferentially displayed so that the display data having a high priority is preferentially displayed. I have to.

Further, for example, when the display data 5 is newly added to page n, the management data of this display data 5 becomes the management data of display data 4 in the storage area of page n of the display data management table 60a. It is then stored. For example, when the display data 5 is graphic data and the color type is green, as the management data of the display data 5, creation order data “5”, type data “graphic”, color type data “green”, display order The data "1" is additionally stored and the display order data of the other display data are changed to low values. That is, the display order data of the display data 1 becomes "5", and hereinafter, the display data 2 is "4", the display data 3 is "3", and the display order data of the display data 4 is "2".
Becomes The display order data is set by referring to the setting method table 60b by the control unit 2 and calculating the display order data based on the setting method set here. In the above case, the setting method of the creation order is set in the setting table 60b, and the display order data is calculated based on the creation order data.

The setting method table storage area 6b is an area for storing the setting method table 60b shown in FIG. In the setting method table 60b, the attribute used as a reference when setting the display order data of the display data is indicated by a flag. FIG. 3 shows that the display order data is determined based on the attribute of the creation order.

The type-based display order table storage area 6c is

The color-based display order table 60d stores display order data indicating the display order for each type of display data color. FIG. 5 shows that the display data of the red color type has the highest display order, followed by blue, yellow, green, and black in that order.

The character pattern generator 7 converts the text data of the document data stored in the document data storage 3 into a corresponding character pattern. The graphic pattern generation unit 8 generates a graphic pattern, which is image data corresponding to the image data stored in the graphic data storage unit 4.

The ruled line pattern generating section 9 generates a ruled line pattern which is image data corresponding to the ruled line data stored in the ruled line data storage section 5.
The display order setting screen data storage unit 10 stores data relating to various setting screens displayed on the display unit 13 when the user sets the display order data of the display data.

The display control section 11 controls the display so that the display data is displayed on the display section 13 based on the display order data stored in the display data management table 60a. Specifically, the display control unit 11 determines, based on the display order data of page n of the display data management table 60a,
The display data is read out in order from the one with the lowest display order (the document data corresponding to the nth page from the document data storage unit 3, the graphic data storage unit 4, and the ruled line data storage unit 5, respectively).
Read out graphic data and ruled line data), display buffer 1
Output to 2. That is, the display control unit 11 causes the display buffer 12 to store display data having a low display order first, and then overwrites display data having a high display order to store the display data having a high display order. To preferentially create composite display data displayed on the front of the display screen. For example, as shown in FIG. 15, display data 4, display data 3,
When the display data 2 and the display data 1 are set, the display control unit 11 refers to the display data management table 60a and the display data management table 60a shows the display data 1 having the lowest display order.
Is identified and the image data relating to this display data 1 is extracted from the graphic data storage unit 4, then the graphic pattern of this display data 1 is acquired via the image pattern generation unit 8 and output to the display buffer 12. . Subsequently, the display control unit 11 refers to the display data management table 60a again, identifies that the display data 1 has the next lowest display order, and then the document data storage unit 3
Extract the text data related to display data 2 from
The character pattern corresponding to the text data of the display data 2 is acquired via the character pattern generation unit 7 and output to the display buffer 12. At this time, the display buffer 12
At this time, the newly output display data 2 is overwritten and stored on the already stored display data 1 to create composite display data in a state in which the display data 2 overlaps the display data 1. Subsequently, the display control unit 11 extracts the ruled line data relating to the display data 3 from the ruled line data storage unit 4 for the display data 3 having the lower display rank subsequent to the display data 2, and the display data 3 via the ruled line pattern generation unit 9. The ruled line pattern of is acquired and output to the display buffer 12. Finally, the display control unit fetches the image data relating to the display data 4 from the graphic data storage unit 4, acquires the graphic pattern of this display data 4 via the graphic pattern generation unit 8, and outputs it to the display buffer 12. In this way, the display control unit 11 acquires the respective patterns relating to the display data 1 to 4 and sequentially outputs the patterns to the display buffer 12, so that the display data 1, the display data 2, the display data 3, and the display data 4 overlap. Create composite display data for states. The composite display data created in this way is output to and displayed on the display unit 13.

The display buffer 12 temporarily stores various data displayed on the display unit 13. Display 1
A liquid crystal display (LCD) 3 displays various data stored in the display buffer 12, for example.

Next, the operation of the present invention will be described with reference to the flowchart of FIG. FIG. 6 is a flowchart showing a process of setting display order of display data. It should be noted that each table stored in the management data storage unit 6 will be described as being in a state in which the following initial values are set. That is, the display order data of the display data management table 60a is set based on the display order data of the display data as shown in FIG.

In the display order item table 60b, the flag corresponding to the order of creation is "1" so that the display order data of the display data is calculated based on the order of creation data.
And other flags are set to "0". In the type-specific display order table 60c, the document display order data is set to "1", the figure display order data is set to "2", and the ruled line display order data is set to "3" as initial values.
In the color-based display order table 60d, as the initial values, the red display order data is "1", the blue display order data is "2",
The yellow display order data is set to "3", the green display order data is set to "4", and the black display order data is set to "5".

The display order for the type of color is not limited to the above-mentioned display order. For example, chromatics (color (wavelength) of visible light, physical quantity such as luminous intensity, illuminance, brightness, etc.) and physical quantity of this visible light (Study for finding relationships with human color perception)
It may be determined based on the theory such as.

With each table thus initialized, the control section 2 first determines whether or not the display order change key 1a of the input section 1 has been operated by the user (step A1). If so, the process proceeds to step A2, while if not operated, the process returns to step A1.

Here, display data of n pages is displayed on the display screen, and when the cursor is present in the n pages, the display order change key 1a is operated to display the data belonging to the n pages. It shall be an instruction to set the display order for data.

Display order setting key 1 in the process of step A1
When it is determined that a has been operated, the control unit 2 causes the display control unit 11 to display the setting method selection screen (see FIG. 1) on the display unit 13.
It is shown in FIG. ) Is displayed (step A2). That is, the control unit 2 takes out data relating to the setting method selection screen from the display order setting screen data storage unit 10 and outputs it to the display control unit 11. The display control unit 11 outputs data regarding the setting method selection screen input from the control unit 2 to the display buffer 12. The display unit 13 has a display buffer 12
A setting method selection screen is displayed based on the data output to. The contents shown in the management table display area in the setting method selection screen are displayed on the basis of the stored management data of each display data by referring to the display data management table storage area 6a.

When the setting method selection screen is displayed on the display unit 13, the user sees this and selects the method of setting the display order of the display data. Here, the user inputs the number of a predetermined selection item among the displayed selection items with the numeric key 1d.

The control unit 2 monitors whether or not the numerical data is input by the user, and determines that the display order setting method is selected when the numerical data is input by the user (step A3). Yes), the input numeric data is accepted (step A4). On the other hand, when the user does not input the numerical data, it is determined that the display order setting method has not been selected (N in step A3).
o), this process is repeated until the user inputs numerical data.

When the input numerical data is accepted in step A4, the control section 2 identifies the display order setting method selected by the user based on the accepted numerical data (step A5). When the numerical data input by the user is “1” (“Select 1” in step A5), the control unit 2 moves to the display order setting process (step A6) based on the creation order. Further, at this time, “1 setting in order of creation” in the setting method of display order on the setting method selection screen is highlighted. In FIG. 11, the bold line is used for highlighting. If the numerical data input by the user is "2"("Select2" in step A5), the control unit 2 moves to display order setting processing for display data units (step A7). When the numerical data is "3"("Select3" in step A5), the control unit 2 moves to the display order setting process for each type (step A8). Also,
When the numeral data is "4"("Select4" in step A5), the control unit 2 moves to display order setting processing for each color type (step A9). (Display Order Setting Process Based on Creation Order) First, the user inputs numeric data “1” (“Select 1” in step A5 of FIG. 6), and the control unit 2 displays order setting process based on the creation order (FIG. A case of performing step A6) of 6 will be described. This specific operation is shown in FIG.

The control unit 2 sets the flag corresponding to the item of "creation order" in the setting method table 60b to "1", and sets the flags of other items to "0" (step B).
1). The flag corresponding to the item of "creation order" is already "1"
If it is, the flag is not set and the process proceeds to the next process.

When the flag is set, next, the control unit 2
Sets the display order data based on the display order data of the display data, and displays the set display order data on the setting method selection screen (step B2). That is, the control unit 2 reads the creation order data relating to the display data of page n of the display data management table 60a, and sets the display order data such that the display order increases from the latest display data based on this creation order data. Then, the set display order data is output to the storage area of the management data of the display data of page n of the display data management table 60a. Further, the display order data of each display data is displayed in the display order data display area 110 in the management table area of the setting method selection screen.

In the description, the display order data is set so that the display order becomes higher from the latest display data.
The display order data may be set so that the display order data becomes higher from the oldest display data. (Display Order Setting Process of Display Data Unit) Next, the user inputs the numeric data “2” (“Select 2” in step A5 of FIG. 6), and the control unit 2 sets the display order of the display data unit. A case of performing (step A7 in FIG. 6) will be described. The specific operation of this processing is shown in FIG. In this processing, the user individually sets the display order of each display data on the display order setting screen for each display data shown in FIG.

The control unit 2 receives the numerical data "2" from the user.
When it is determined that the input has been made, the flag corresponding to the item of "display data unit" of the setting method table 60b is set to "1", and the flags of other items are set to "0" (step C1). If the flag corresponding to the item of “display data unit” is already “1”, the flag is not set and the process proceeds to the next process.

When the flag is set, the control section 2 causes the control of FIG.
As shown in FIG. 2, a display order setting screen for each display data unit is displayed on the display unit 13 (step C2). When the display order setting screen for each display data is displayed on the display unit 13, the control unit 2 receives the display order data input by the user to the display order input area 120a (step C).
3). To input the display order data of this user, after operating the cursor key 1c to move and display the cursor at the position corresponding to the predetermined display data in the display order input area 120a,
This is done by operating the numeric keys 1d to input numeric data.

When the display order data is input, the control unit 2
Outputs the input display order data to the management data storage area of the display data of page n of the display data management table 60a, and sets the display order data of each display data to the value of the input display order data. . The control unit 2 also displays the input display order data in the display order input area 120a via the display control unit 11 and the display buffer 12. Here, the control unit 2 determines, based on the position information of the cursor, which display data corresponds to which display order data is input. In this way, the control unit 2 accepts the input of the display order data from the user until the display order data is input for all the display data. FIG. 12 shows a display order setting screen after the display order of each display data is set.

Next, the control unit 2 confirms whether the display order data input by the user is consistent (step C).
4). For example, the display order data of the display data 1 is "4", the display order data of the display data 2 is "4", the display order data of the display data 3 is "1", and the display order data of the display data 4 is "2". As described above, when there is an overlap in the input display orders, it is determined that there is a contradiction (Yes in step C4), and the control unit 2 causes the display control unit 11
A warning indicating that there is a contradiction in the display order data input to the display unit 13 via is displayed (step C5). After that, in order to accept the display order data input by the user again to correct the display order data, step C
Return to the process of 3.

On the other hand, when there is no contradiction in the input display order data (No in step C4), the control section 2 determines whether or not the user operates the select / execute key 1b (step C6). . The user inputs the display order input area 120a
When the select / execute key 1b is operated to confirm the display order data displayed on the display and display the display data based on the display order data, the control unit 2 selects
It is determined that the operation key 1b is operated (step C6).
“Yes”), the display data is displayed in accordance with the input display order data, and thus the process proceeds to step A10 in FIG. (Display Order Setting Processing for Each Type) Next, the user inputs numeric data “3” (“Select 3” in step A5 of FIG. 6), and the control unit 2 sets the display order for each type of display data. A case where the processing (step A8 in FIG. 6) is performed will be described. The specific operation of this processing is shown in FIG.

In this process, display order data is set according to the type of display data on the type-specific display order setting screen shown in FIG. When the control unit 2 determines that the user has input the numerical data “3”,
The flags corresponding to the "type-specific" items of the setting method table 60b are set to "1", and the flags of the other items are set to "0" (step D1). If the flag corresponding to the item of "by type" is already "1", the flag is not set and the process proceeds to the next process.

When the flag is set, the control section 2 causes the control of FIG.
The display order setting screen for each type shown in 3 is displayed on the display unit 13 (step D2). When the display order setting screen for each type is displayed on the display unit 13, the control unit 2 receives the input of the display order data indicating the display order for the type of display data from the user (step D3). That is, the control unit 2
The input display order data is accepted and is output to the type-based display order table 60c to set the display order data corresponding to the type of display data to the value of the input display order data. The control unit 2 also displays the display order data for the type of display data in the display order input area 130a via the display control unit 11 and the display buffer 12.
In this way, the control unit 2 accepts the input of the display order data from the user until the display order data is input for all types.

Next, the control unit 2 confirms whether the display order data input by the user is consistent (step D
4) If there is a contradiction (Yes in step D4),
A warning message indicating that the display order data input to the display unit 13 is inconsistent is displayed (step D5). Then, the process returns to step D3 to accept the display order data input by the user again to correct the display order data.

On the other hand, when there is no contradiction in the input display order data (No in step D4), the control unit 2 controls the display order data of the type-specific display order table 60c and the creation order data of the display data management table 60a. Based on, the display rank data of each display data is calculated. In the calculation of the display order data, when there are a plurality of display data of the same type, the display order data of the newly created display data is calculated to be higher according to the order of display data creation. For example, in the case of FIG. 13, the display order data between the display data 1 and the display data 4 which are the same “graphic” is calculated so that the display data 4 is higher than the display data 1. Therefore, as shown in FIG. 13, the display order data of the "document" type is "1", the display order data of the "graphic" type is "3", and the display order data of the "table" type is "2". When set as, the control unit 2 sets the display order data of the display data 2 of the type “document” to “1”,
The display order data of the display data 3 of the "table" type is "2", the display order data of the display data 4 having the type of "graphic" and the creation order of "4" is "3", the type of "graphic" In addition, the display order data of the display data 1 whose creation order is "1" is calculated as "4".

When the control unit 2 calculates the display order data,
The calculated display order data is output to the storage area of the management data of the display data of page n of the display data management table 60a. Further, the display order data of each display data is displayed in the display order data display area 130b (step D).
6).

When the display order data of each display data is displayed in the display order data display area 130b, the control section 2 determines whether or not the user operates the select / execute key 1b (step D7). The user inputs the display order input area 130b
When the selection / execution key 1b is operated to confirm the display order data displayed on the display and to instruct the display of the display data based on the display order data, the control unit 2 causes the selection / execution key 1b to be operated. It is determined that the data has been broken (“Yes” in step D7), and the display data is displayed in accordance with the set display order data. Therefore, the process proceeds to step A10 in FIG. (Process for setting display order for each color type) Next, the user inputs numerical data “4” (“4” in step A5 in FIG. 6).
, ”), And a case where the control unit 2 performs a display order setting process for each color type of display data (step A9 in FIG. 6). The specific operation of this processing is shown in FIG.

In this process, the display order is set according to the color type of the display data on the display order setting screen for each color type shown in FIG. When the control unit 2 determines that the user has input the numerical data “4”,
The flags corresponding to the "color type" items of the display method table 60b are set to "1", and the flags of the other items are set to "0" (step E1). Already "by color type"
When the flag corresponding to the item is "1", the flag is not set and the process proceeds to the next process.

When the flag is set, the control section 2 is set as shown in FIG.
The display order setting screen for each color type is displayed on the display unit 13 (step E2). When the display order setting screen for each color type is displayed, the user operates the cursor key 1c to move the cursor to a position corresponding to a predetermined type-specific item in the display order input area 140a, and then the numeric key 1d. By inputting numerical data by operating, the display order data indicating the display order for the color type is input.

When the display order data is input by the user, the control section 2 accepts the display order data (step E3) and displays it in the color type-based display order table 60c.
The display order data corresponding to each color type item is set to the value of the input display order data. Also,
The control unit 2 displays the display order data input to the display order input area 140a via the display control unit 11 and the display buffer 12. In this way, the control unit 2 until the display order data is input for all color type items,
Input of display order data from the user is accepted.

Next, the control unit 2 confirms whether or not the display order data input by the user is inconsistent (step E
4) If there is a contradiction (Yes in step E4),
A warning message indicating that the display order data input to the display unit 13 is inconsistent is displayed (step E5). After that, the process returns to step E3 to accept the display order data input by the user again to correct the display order data.

On the other hand, when there is no contradiction in the input display order data (No in step E4), the control unit 2 controls the display order data in the color-type-specific display order table 60c and the page n of the display data management table 60a. The display rank data of each display data is calculated based on the creation order data regarding the display data of. The calculated display order data is output to the storage area of the management data of the display data of page n of the display data management table 60a. Further, the calculated display order data of each display data is displayed in the display order data display area 140b (step E6). Here, when there are a plurality of display data belonging to the same color type, the display order data of the newly created display data is increased. When the display order data for the item of the color type is input as shown in the display order input area 140a of FIG. 14, the control unit 2 sets the display order data of the display data 1 belonging to the color type of “blue” to “1”, The display order data of the display data 4 belonging to the color type of "red" is "2", the display order data of the display data 3 belonging to the color type of "yellow" is "3", the display data belonging to the color type of "white" The display order data of 2 is calculated as "4".

When the display order data of each display data is displayed in the display order data display area 140b, the control section 2 determines whether or not the user operates the select / execute key 1b (step E7). The user inputs the display order input area 140b
When the selection / execution key 1b is operated so as to confirm the display order data displayed on the display and display the display data based on the display order data, the control unit 2 operates the selection / execution key 1b. (Step E7, “Y
es "), the display data is displayed according to the set display order data, and thus the process proceeds to step A10 in FIG. (Display Processing of Display Data Based on Set Display Order) As described above, step A6 to step A9 in FIG.
