Embodiment 1 FIG.
FIG. 1 is an overall configuration diagram of a programmable display according to Embodiment 1 for carrying out the present invention. In FIG. 1, 100 is a programmable display, 101 is an operator who operates the programmable display 100, and 102 is an external device connected to the programmable display 100.

Reference numeral 11 denotes an input unit that receives an instruction input from the operator 101, and inputs an operation instruction for a predetermined function corresponding to the function area and an area selection instruction for enlarging or reducing the display area. Here, when an instruction input by the operator 101 is within the function area, an operation instruction is given. On the other hand, when the instruction input by the operator 101 is outside the function area, it becomes a region selection instruction, and this instruction input position becomes the coordinates of the start point for determining the selection region. If the instruction input by the operator 101 is an area selection instruction, the operator 101 further inputs the end point coordinates by the instruction input, and the selection area is determined by the start point coordinates and the end point coordinates.

Reference numeral 12 denotes a display means for displaying an object composed of display data. The input means 11 and the display means 12 are arranged so as to overlap each other as shown in FIG. An external device connection interface 13 is connected to the external device 102. Reference numeral 20 denotes an overall processing unit, and 21 denotes a display generation unit which is a display generation unit. A data storage unit 22 stores display data, operation data, and the like. The programmable display 100 includes an input unit 11, a display unit 12, an external device connection interface 13, an overall processing unit 20, a display generation unit 21, and a data storage unit. 22. The object is composed of display data, the function area is composed of operation data, and the display data and operation data share the same coordinate system.

FIG. 3 is an internal configuration diagram of the overall processing unit 20 configuring the programmable display device 100. In FIG. 3, reference numeral 30 denotes an input determination unit that determines whether an instruction input by the operator 101 is an operation instruction or a region selection, and issues a command corresponding to the determined content. 31 is an area coordinate calculation means, 32 is an enlargement / reduction ratio calculation means, 33 is a function area area calculation means, and 34 is a function processing section. The overall processing section 20 is an input determination means 30, an area coordinate calculation means 31, an enlargement / reduction ratio. The calculation unit 32, the function area region calculation unit 33, and the function processing unit 34 are configured.

Next, regarding the operation, a flowchart of the operation of the programmable display 100 shown in FIG.
Following the enlarged display of the programmable display shown in FIG. 5 and FIG. 5 is a screen when selecting an area in the normal state, and FIG. 6 is a screen when displaying an enlarged image. In the figure, since the input means 11 and the display means 12 constitute a touch panel, the function areas 301a to 301d existing on the coordinate plane of the input means 11 and the objects 302a to 302 existing on the display means 12 are formed. 302d is configured to exist in the same overlapped region. It is a well-known technique that when an instruction is input to an object by a touch operation or the like, an operation of a function area corresponding to the object for which the instruction is input is performed.

First, in the screen display in the normal state shown in FIG. 5, when there is an instruction input by the operator 101 touching the input means 11 or the like (step S200), the instruction input is converted into input coordinates by the input means 11. Then, the signal is sent to the input determination means 30 constituting the overall processing unit 20. The input determination unit 30 refers to the operation data stored in the data storage unit 22 and stores the operation data in the input determination unit 30 and determines whether the transmitted signal is a region selection or an operation. (Step S201). When the input coordinate value by the input unit 11 matches the coordinate value (range) of the predetermined function area, it is determined that the instruction input signal is an operation (operation in step S201), and the function processing unit 34 The function assigned to the function area of the object arranged on the input coordinates displayed on the display means 12 is executed (step S207).

On the other hand, if the input coordinate value by the input means 11 does not match the predetermined coordinate value (range) of the function area in step S201, the instruction input by the operator 101 specifies the selection area for enlarging the screen. (Region selection in step S201). That is, in order to enlarge the designated display area and display it on the display means 12, the input determination means 30 uses the coordinate value converted into the input coordinates by the input means 11 as the start point (x _S , y _S ) of the selection area 300. Is output to the area coordinate calculation means 31. Subsequently, the instruction input point input by the operator 101 is output to the area coordinate calculation means 31 as the end point (x _S + e, y _S + f) of the selection area 300. The area coordinate calculation unit 31 selects a rectangular area whose diagonal is a start point (x _S , y _S ) and an end point (x _S + e, y _S + f) inputted by a touch operation or the like by the operator 101 to be enlarged. The area 300 is calculated (step S202).

Next, the signal is sent from the area coordinate calculation means 31 to the enlargement / reduction ratio calculation means 32. The enlargement / reduction ratio calculation means 32 calculates a magnification for displaying the selected area 300 calculated by the area coordinate calculation means 31 on the display means 12 (step S203). For example, with respect to the magnification in the case of full-screen display by simple enlargement, the coordinates for determining the selection area 300 in the origin coordinates (x ₀ , y ₀ ) and maximum coordinates (x ₀ + m, y ₀ + n) of the display screen are the start points ( When x _S , y _S ) and the end point (x _S + e, y _S + f), the area coordinate calculation means 31 is _x / m in the X direction and _x / _{y in the} Y direction for full screen display. Calculated as n / f.

The display generation unit 21 regenerates the display data according to the magnification calculated by the enlargement / reduction ratio calculation unit 32 (step S204), and the display unit 12 displays the display data regenerated by the display generation unit 21. It is displayed (step S205). First, since the display generation unit 21 moves the start point (x _S , y _S ) of the selection area 300 to the origin coordinates (x ₀ , y ₀ ) of the display screen, all of the display data existing in the selection area 300 is displayed. to coordinate subtracts x _S from the X-coordinate value, subtracting y _S from the Y-coordinate values. Next, in order to display the selected area 300 in an enlarged manner, the display generation unit 21 multiplies each X coordinate value by the magnification q _x for each coordinate of the display data existing in the selected area 300, and each Y The coordinate value is multiplied by the magnification q _y . In this way, the display generation unit 21 regenerates the enlarged display data.

On the other hand, in parallel with regenerating the display data in the display generation unit 21, the function area area calculation unit 33 exists in the selection area 300 according to the magnification calculated by the enlargement / reduction ratio calculation unit 32. In order to enlarge the function area to be expanded in the same manner, the coordinates and area of the enlarged function area are calculated with reference to the operation data stored in the data storage unit 22 (step S206). Thereafter, the function area region calculating unit 33 sends the enlarged operation data to the input determining unit 30 and re-stored in the input determining unit 30.

When the coordinates for determining the function area 301d to be enlarged are the first coordinates (x ₁ , y ₁ ) and the second coordinates (x ₁ + a, y ₁ + b), the start point (x _S , y _S ) of the selection area 300 is set. Corresponding to the movement to the origin coordinates (x ₀ , y ₀ ), the function area area calculation means 33 subtracts x _S from each X coordinate value for all the coordinates of the operation data existing in the function area 301d. Then, y _S is subtracted from each Y coordinate value. As a result, the first coordinates move to (x ₁ −x _S , y ₁ −y _S ), and the second coordinates move to (x ₁ + ax− _s , y ₁ + by− _S ), respectively.

Next, the function area region calculation unit 33 multiplies each X coordinate value by a magnification q _x for all the coordinates of the operation data existing in the function area 301d in order to enlarge the function area 301d. Each Y coordinate value is multiplied by a magnification q _y . As a result, the first coordinate _{(q x · (x 1 -x} S), q y · (y 1 -y S)) , the second coordinate _{(q x · (x 1 +} a-x S), q Each moves to _y · (y ₁ + by− _S )). In this way, the function area also changes the magnification following the regenerated display data, and corresponds to the instruction input from the operator 101.

In the above description, the example in which the selection area 300 by the operator 101 is enlarged and the function area 301d is enlarged is described. However, as the processing by the operator 101 after the enlarged display, the operator 101 is enlarged. By an instruction input by touching the inside of the function area 301d, an operation assigned to the function area 301d that has received the instruction input is performed. On the other hand, an instruction input by touching outside the function area 301d becomes a screen return instruction, and control is performed so that the enlarged display is canceled and the display screen returns to the basic normal display screen.

When the outside of the function area 301 d is touched, the instruction input is converted into input coordinates by the input unit 11, and the signal is sent to the input determination unit 30. The input determination unit 30 refers to the operation data stored in the input determination unit 30. Since the operation data is the operation data that has been enlarged, the input determination unit 30 enlarges the currently displayed screen. Recognize that the displayed screen. Then, the input determination unit 30 refers to the operation data stored in the data storage unit 22 and stores the operation data in the input determination unit 30 as well as the origin coordinates (x ₀ , y ₀ ) and the maximum of the display screen. The coordinates (x ₀ + m, y ₀ + n) are output to the area coordinate calculation means 31.

The area coordinate calculation means 31 calculates a rectangular area determined by the origin coordinates (x ₀ , y ₀ ) and the maximum coordinates (x ₀ + m, y ₀ + n) as the selection area 300. Scaling ratio calculating means 32 recognizes that region of the display screen of the display and the selection area 300 calculated by the area coordinate calculation unit 31 means 12 are the same, magnification q _x and Y direction of the X-direction magnification Both q _y are calculated as 1 times.

The display generation unit 21 recognizes that the magnification calculated by the enlargement / reduction ratio calculation unit 32 is 1, and regenerates the display data in the normal state. Then, the display unit 12 displays the display data in the normal state regenerated by the display generation unit 21. The function area area calculation unit 33 also recognizes that the magnification calculated by the enlargement / reduction ratio calculation unit 32 is 1, and refers to the operation data stored in the data storage unit 22 so that the function in the normal state Calculate area coordinates and area.

Although it is desired to input an instruction to select an area in the vicinity of the function area on the input unit 11, an instruction may be input in the function area by mistake and an operation instruction may be executed. In order to prevent such a malfunction, an area selection instruction on the input unit 11 is accepted by a forced instruction input from the external apparatus 102 via the external apparatus connection interface 13, but an operation instruction is not accepted. It is also possible to execute an interlock such as an enlargement-only mode function. When it is desired to execute the enlargement-only mode function, in addition to the forced instruction input method from the external device 102, the enlargement-only mode function is executed with reference to instruction data stored in the data storage unit 22 in advance. It is possible.

According to the first embodiment, since a part of the screen displayed on the display means 12 can be displayed in an enlarged or reduced manner, objects and function areas are arranged with high density on one screen, and information is displayed. While performing the display, the display can be enlarged or reduced as necessary to confirm the details of the information or the entire information.

Further, following the enlarged display of the objects 302c and 302d surrounded by the selection area 300, the function areas 301c and 301d operate so as to enlarge, so the objects and function areas are arranged with high density on one screen, While displaying information, it is easy to select the objects 302c and 302d by enlarging the display as necessary, so that a reliable selection operation is possible.

Furthermore, by executing interlock by forced instruction input from the external device 102 via the external device connection interface 13 or interlock by instruction data stored in the data storage unit 22, Prevention is possible.

Embodiment 4 FIG.
FIG. 10 is a flowchart showing an example in which the enlarged display of the programmable display device according to the fourth embodiment for carrying out the present invention is linked to the instruction input outside the function area. In the flowchart shown in FIG. The operation setting A for selecting whether the input from the operator 101 described in the first embodiment is an area selection instruction or an operation instruction, and if the input from the operator 101 is within the function area, it is accepted as an operation instruction. On the other hand, if it is outside the function area, step S208 for switching the operation setting B for enlarging and displaying the area centered on the input coordinate instead of the area selection instruction, and whether or not the input coordinate falls within the function area of the object are determined. In step S209, the enlarged display data for enlarging the area centered on the input coordinates is displayed. Step S210 of forming have been added. Steps S200 to S207 are the same as those in FIG.

Next, the operation will be described with reference to the flowchart shown in FIG. Which operation setting is to be set in the data storage unit 22 is stored in advance as instruction data, and the input determination means 30 switches between the operation setting A and the operation setting B based on this instruction data. When the operation setting B is switched (B in Step S208), when there is an instruction input by the operator 101 touching the input means 11 or the like next, the instruction input is converted into input coordinates by the input means 11, The signal is sent to the input determination means 30. The input determination means 30 refers to the operation data stored in the data storage unit 22 and stores the operation data in the input determination means 30 and whether the transmitted signal is within the function area or outside the function area. It is determined whether or not there is (step S209).

When the input coordinate value by the input means 11 is outside the function area (No in step S209), the area coordinate calculation means 31 calculates the selection area 300, but the operator 101 inputs coordinates outside the function area in advance. Then, the values k and l are stored in the data storage unit 22 so that the selection region 300 of ± k in the X direction and ± l in the Y direction is determined around the input coordinates, and the operation setting B is set. Simultaneously with the switching, the input determination unit 30 refers to the values of k and l from the data storage unit 22 and stores the values of k and l in the input determination unit 30. The area coordinate calculation means 31 calculates a selection area using the input coordinates input by the operator 101 and the values of k and l sent from the input determination means 30. Then, after the magnification of the entire display is calculated by the enlargement / reduction ratio calculation means 32 or the numerical value stored as the instruction data in the data storage unit 22 is determined as the magnification, the display means 12 is regenerated by the display generation unit 21. Display data is displayed (step S210).

In parallel with regenerating display data in the display generation unit 21, the function area area calculation unit 33 functions in the selection area 300 according to the magnification calculated by the enlargement / reduction ratio calculation unit 32.

Embodiment 5 FIG.
In the fifth embodiment for carrying out the present invention, a method for displaying the entire display data having a resolution different from the resolution of the programmable display 100 will be described. FIG. 11 is a flow chart when processing display data of a programmable display in the fifth embodiment for carrying out the present invention, and FIGS. 12 to 14 show a programmable display showing the fifth embodiment of the present invention. It is a schematic diagram at the time of implementing the display data processing of the vessel. 12 shows a display screen with a resolution of SVGA, FIG. 13 shows a display screen with a resolution of VGA and reduced display, and FIG. 14 shows a display screen with a resolution of VGA and partial display. The resolution of SVGA is 800 pixels × 600 pixels, the resolution of VGA is 640 pixels × 480 pixels, and the resolution of SVGA is larger than the resolution of VGA.

Next, with respect to the operation, the display data with the resolution of SVGA shown in FIG. 12 is reduced on the programmable display with the resolution shown in FIG. 13 or partially displayed on the programmable display with the resolution shown in FIG. This will be described with reference to the flowchart shown in FIG. First, when displaying a screen having a resolution of SVGA different from the resolution of the programmable display 100, display data having a resolution of SVGA is stored in the data storage unit 22 in advance. The display generation unit 21 receives display data whose resolution is SVGA stored in the data storage unit 22 from the data storage unit 22 and starts resolution conversion of the display data (step S210). Next, the display generation unit 21 determines whether or not the resolution of the display data after conversion is larger than the resolution of the programmable display device 100 (step S211). If the resolution is small (small in step S211), the display data is enlarged. Then, the entire screen is displayed (step S215).

If the resolution is high (large in step S211), the programmable display 100 displays on the display means 12 that the resolution is high, and the operator 101 inputs an instruction whether to perform partial display or reduced display (step S212). .

In the case of reduced display (step S213), the display generation unit 21 sends the converted display data to the area coordinate calculation means 31. The area coordinate calculation means 31 uses the origin coordinates (x ₀₀ , y ₀₀ ) and the maximum coordinates (x ₀₀ + g, y ₀₀ + h) of the display data with the resolution SVGA as diagonal lines on the display screen with the resolution SVGA shown in FIG. The rectangular area thus calculated is calculated as a selection area 300 to be reduced and displayed.

Next, the signal is sent from the area coordinate calculation means 31 to the enlargement / reduction ratio calculation means 32. The enlargement / reduction ratio calculation means 32 calculates a magnification for reducing and displaying the selected area 300 calculated by the area coordinate calculation means 31 on the display means 12. For example, regarding the magnification in the case of full-screen display, the selection area 300 is set at the origin coordinates (x ₀ , y ₀ ) and maximum coordinates (x ₀ + m, y ₀ + n) of the display screen of the programmable display whose resolution is VGA. When the coordinates to be determined are the start point (x ₀₀ , y ₀₀ ) and the end point (x ₀₀ + g, y ₀₀ + h), the area coordinate calculation means 31 uses the magnification _{x x in} the X direction for full screen display as m / g, Y The direction magnification q _y is calculated as n / h.

The display generation unit 21 regenerates display data according to the magnification calculated by the enlargement / reduction ratio calculation unit 32, and the display unit 12 displays the display data regenerated by the display generation unit 21. First, as illustrated in FIG. 13, the display generation unit 21 sets the start point (x ₀₀ , y ₀₀ ) of the selection region 300 as the origin coordinates (x ₀ , y ₀ ) of the display screen of the programmable display whose resolution is VGA. . Next, in order to display the selected area 300 in a reduced size, the display generation unit 21 multiplies each X coordinate value by a magnification q _x for each coordinate of the display data existing in the selected area 300, and each Y The coordinate value is multiplied by the magnification q _y . In this way, the display generation unit 21 regenerates the reduced display data.

In the case of partial display (step S214), the display generation unit 21 sends the converted display data to the area coordinate calculation means 31. In the display data whose resolution is SVGA shown in FIG. 12, if the start point coordinates of the display screen desired to be partially displayed by the operator 101 are (x _V , y _V ), the end point coordinates are displayed on a programmable display whose resolution is VGA. From the screen widths m and n, it is uniquely (x _V + m, y _V + n), and the area coordinate calculation means 31 uses the start point (x _V , y _V ) and the end point (x _V + m, y _V + n) as a diagonal line. The rectangular area thus calculated is calculated as a selection area 300 to be partially displayed.

Next, the signal is sent from the area coordinate calculation means 31 to the enlargement / reduction ratio calculation means 32. Scaling factor calculation unit 32, for displaying partial selection area 300 calculated by the area coordinate calculation unit 31 to the display unit 12, the magnification q _y magnification q _x and Y direction of the X-direction are both 1-fold and calculation To do.

The display generation unit 21 regenerates the display data, and the display unit 12 displays the display data regenerated by the display generation unit 21. First, as shown in FIG. 14, the display generation unit 21 moves the start point (x _V , y _V ) of the selection area 300 to the origin coordinates (x ₀ , y ₀ ) of the display screen of the programmable display whose resolution is VGA. order to, for all coordinates of the display data that exists in the selection area 300, subtracts x _V from the X-coordinate value. Further, by subtracting the _{y V} from the Y-coordinate value, as a result, the end point _{(x V + m, y V} + n) of the selected region 300, the maximum coordinates of the display screen of the programmable display resolution is VGA _(x 0 + m , Y ₀ + n). In this way, the display generation unit 21 regenerates the partially displayed display data.

If the resolution is small (small in step S211), the display generation unit 21 sends the converted display data to the area coordinate calculation unit 31, and regenerates the enlarged display data through the enlargement / reduction rate calculation unit 32. However, the regeneration procedure is the same as the procedure described in the first embodiment, and a description thereof will be omitted.

On the other hand, in parallel with regenerating display data in the display generation unit 21, the function area region calculation unit 33 is calculated by the enlargement / reduction ratio calculation unit 32 as in the procedure described in the first embodiment. According to the magnification, in order to convert the function area existing in the selection area 300 in the same manner, the coordinate and area of the converted function area are calculated with reference to the operation data stored in the data storage unit 22. Thereafter, the function area area calculation unit 33 sends the converted operation data to the input determination unit 30 and is re-stored in the input determination unit 30.

The programmable display device 100 configured as described above operates to generate an enlarged display, a reduced display, or a partial display according to the resolution of the display data. Then, the function area calculation unit 33 enlarges / reduces or partially displays the function area in accordance with the entire display of display data having different resolutions.

According to the fifth embodiment, since display data and operation data having a resolution different from that of the programmable display device 100 can be displayed, it is not necessary to create and manage screen data according to different resolutions. Since it is possible to collectively manage with one screen data, complexity can be reduced.
