The input device 200 includes an input device that inputs operation coordinates on a screen such as a mouse or a touch panel. The storage device 300 includes a hard disk device and a semiconductor memory, and stores various environment setting information. The output device 400 is a display that displays various drawing objects.

The processing apparatus 100 includes an operation coordinate detection unit 101, a display layout unit 102, a display size determination unit 103, an operation count monitoring unit 104, and a display state management unit 105.
The operation coordinate detection unit 101 is a functional unit that detects coordinates on a screen selected by a mouse or a touch panel obtained from the input device 200. The display layout unit 102 is a functional unit that manages screen display information such as what drawing object is displayed at which position on the screen, and a layout management unit 102a that manages the display position of the displayed drawing object. And a screen display control unit 102b for transmitting a screen to be displayed to the output device 400.

  The display size determination unit 103 corresponds to the operation coordinate when the operation coordinate detection unit 101 detects one of the operation coordinates and the display layout unit 102 manages a drawing object corresponding to the coordinate. This is a functional unit that calculates the enlargement ratio of the drawing object and calculates the reduction ratio in a state in which the aspect ratio of the drawing object other than the enlargement target object is maintained. The display size determination unit 103 enlarges a drawing object, an enlargement / reduction calculation unit 103a that calculates a size when a drawing object other than the enlarged drawing object is reduced, and a maximum enlargement size management unit 103b that manages the upper limit of the enlargement size. And. The maximum enlargement size managed by the maximum enlargement size management unit 103b is specified by the environment setting information stored in the storage device 300, and is read and registered when the display device is activated when the power is turned on. The operation frequency monitoring unit 104 monitors how many times the selected drawing object has been selected after activation based on the operation coordinate information of the operation coordinate detection unit 101 and the management position information of the drawing object of the layout management unit 102a. It is a functional part to do. The display state management unit 105 is a functional unit for managing whether or not the display state of the screen is an enlarged display.

  The operation coordinate detection unit 101 to the display state management unit 105 are configured by software corresponding to each function and hardware such as a CPU and a memory for executing the software. Alternatively, some or all of the operation coordinate detection unit 101 to the display state management unit 105 may be configured by dedicated hardware.

Next, the operation of the display device of Embodiment 1 will be described.
First, the display example of this Embodiment 1 is demonstrated using FIG.2 and FIG.3. As shown in FIG. 2, it is assumed that drawing objects are displayed side by side in a tile shape. If any drawing object is selected in this state (indicated by clicking in the figure), the selected drawing object is displayed in an enlarged manner. At this time, drawing objects other than the selected one are reduced and displayed while maintaining the aspect ratio. FIG. 3 shows an example in which when the same graphic object selected in FIG. 2 is selected, the selected drawing object is displayed in an enlarged manner, but is enlarged and displayed larger than the enlarged size in FIG. In the case of FIG. 3, the selected drawing object has a large number of accumulated operations, and the enlargement size is determined in accordance with the accumulated number of operations. In the first embodiment, what is represented by a plurality of drawing objects is an object including an image representing a device such as a meter or a lamp.

Next, the operation of each part when performing such display will be described.
First, when the display device according to the first embodiment is activated when the power is turned on, the processing device 100 reads the environment setting information from the storage device 300, and sets the maximum size when the drawing object is enlarged in the maximum enlarged size management unit 103b. sign up. In addition, information on the size and display position coordinates of each drawing object in the standard display state is read from the storage device 300 and registered in the layout management unit 102 a of the display layout unit 102. The display control operation after activation is as shown in FIGS.

  As illustrated in FIG. 4, when the user performs some operation with the input device 200, the operation coordinate detection unit 101 detects coordinates on the screen operated with the input device 200. Thereby, the display layout unit 102 determines whether or not the display state of the drawing object managed by the display state management unit 105 is an enlarged display state (step ST101). If in the standard display state (NO in step ST101), enlargement / reduction processing (shown in FIG. 5) is performed (step ST107). On the other hand, in the enlarged display state (YES in step ST101), the screen display control unit 102b of the display layout unit 102 acquires the standard display size of each drawing object managed by the layout management unit 102a (step ST102). Then, each drawing object is resized to the standard display size (step ST103). Similarly, the screen display control unit 102b acquires the standard display coordinates of each drawing object managed by the layout management unit 102a (step ST104), and performs display processing of each drawing object using the acquired standard display coordinates (step ST104). ST105). Thereafter, the display state management unit 105 sets the display state of the drawing object to the standard display state (step ST106).

Next, the enlargement / reduction process in the standard display state in step ST101 will be described with reference to FIG.
Some operation is performed by the input device 200, and the coordinates on the screen operated by the operation coordinate detection unit 101 are detected (step ST201). That is, the coordinate information (x, y) on the selected screen is converted into coordinate information (xx, yy) on the display layout that is the coordinate information in the processing apparatus 100. The conversion result is transmitted to the layout management unit 102a in the display layout unit 102.

  The layout management unit 102a determines which drawing object is selected on the screen based on the transmitted coordinate information (step ST202). If there is no corresponding drawing object as a result of the determination, the enlargement process is not performed (NO in step ST203). On the other hand, if there is a drawing object to be enlarged, the operation count monitoring unit 104 counts up (+1) the number of times (the cumulative operation count) that the drawing object to be enlarged has been selected (step ST204 / step ST205). Note that the initial value of the cumulative number of operations is zero.

  Next, the display layout unit 102 requests the display size determination unit 103 to calculate the size of the drawing object to be enlarged. Thereby, the enlargement / reduction calculation unit 103a of the display size determination unit 103 calculates the enlargement size based on the cumulative number of operations of the operation number monitoring unit 104 by setting the enlargement rate by 10% (step ST206). If the calculated enlargement size is larger than the maximum size managed by the maximum enlargement size management unit 103b, the enlargement size is managed as the maximum size (step ST207 / step ST208). Further, the enlargement / reduction calculation unit 103a calculates an empty space based on the enlarged drawing object size, and calculates the display size of the drawing object to be reduced (step ST209). The display size calculation process is shown in FIGS.

Subsequently, the layout management unit 102a calculates the display position of the drawing object to be reduced based on the reduced display size obtained in step ST209 (step ST210), and the display position of the drawing object to be enlarged. Is calculated (step ST211). Furthermore, the display state management unit 105 sets the display state of the drawing object to the enlarged display state (step ST212).
After the enlargement / reduction size is determined by the display size determination unit 103, the display layout unit 102 enlarges / reduces each drawing object to the determined size by the screen display control unit 102b, and transmits it to the output device 400. The output device 400 displays a screen.

Next, the reduced display size calculation process in step ST209 of FIG. 5 will be described with reference to FIGS.
First, as shown in FIG. 6, the enlargement / reduction calculator 103a prepares the vertical and horizontal sizes of the drawing object to be enlarged determined in step ST206 or ST208 and the vertical and horizontal sizes before the enlargement. To do. Next, a difference value (A) from the vertical width of the drawing object to be enlarged is calculated with respect to the vertical width of the window (step ST301). Similarly, the difference value (B) between the window width and the width before enlargement is calculated for the width (step ST302).
Subsequently, a difference value (C) from the vertical width of the enlarged drawing object is calculated with respect to the vertical length of the window (step ST303). Similarly, the value (D) is calculated for the horizontal width (step ST304). Using these values ST to ST304, the vertical and horizontal reduction ratios are calculated (step ST305 / step ST306). The reduction rate calculation processing here is shown in FIG.
In step ST305 / step ST306, since the reduction ratio for the drawing object other than enlargement is calculated, the drawing object other than enlargement is reduced using this (step ST307).

Next, the reduction rate calculation processing in step ST305 / step ST306 in FIG. 6 will be described with reference to FIG.
The vertical and horizontal reduction ratios are calculated using the values A to D calculated in steps ST301 to ST304.
Calculates the percentage (percentage (%)) of how much the vertical width of the empty space generated by placing the drawing object to be enlarged is reduced before and after enlargement with respect to the vertical window size ( Step ST401). Using the calculated ratio (reduction ratio E), the size after reduction of the drawing object other than enlargement is calculated (step ST402). The calculated size of each drawing object after reduction is added, and the size of the drawing object after enlargement is also added (step ST403). It is checked whether or not the value exceeds the window size (step ST404). If not, the reduction ratio is stored (step ST405). If the window size is exceeded in step ST404, step ST405 is not performed and the reduction ratio is set to zero.

  Subsequently, the same calculation as the above-described step ST401 to step ST405 is performed for the horizontal reduction rate F (step ST406 to step ST409). When the vertical or horizontal reduction ratio (E or F) is 0, the reduction ratio other than 0 is used. If both are 0, the reduction process is not performed.

  Based on the above processing, the drawing objects above and below the drawing object to be enlarged reduce the drawing object at the vertical reduction ratio, and the drawing objects at the left and right reduce the drawing object at the horizontal reduction ratio (step ST410). In step ST410, the value of step ST405 may be compared with the value of step ST409, and the reduction ratio used for the result approximating the window size may be selected.

  When the size of the drawing object to be enlarged and the sizes of the other drawing objects are obtained in this way, the layout management unit 102a lays out each drawing object so that the upper, lower, left, and right drawing objects are in contact with each other. Note that the display coordinates of the drawing object to be enlarged move according to the size so that the display position of the drawing object to be reduced vertically and horizontally is not lost by the enlargement (see steps ST210 / ST211 in FIG. 5). The screen display control unit 102b arranges the drawing object to be reduced and draws the enlarged drawing object in the remaining area.

  As described above, according to the display device of the first embodiment, when an operation instruction is given to any position on the screen, the operation coordinate detection unit that detects the position as the operation coordinates, One of the operation coordinates is detected by the display layout unit that manages the display position of the drawing object, the operation number monitoring unit that monitors the number of operations on any drawing object, and the operation coordinate detection unit, and corresponds to the operation coordinate When the displayed drawing object is managed in the display layout unit, the enlargement ratio of the drawing object corresponding to the operation coordinates is calculated according to the number of operations of the drawing object, and the aspect ratio of the drawing object other than the enlargement target drawing object is calculated. A display size determining unit that calculates a reduction ratio in a maintained state, and the display layout unit is calculated by the display size determining unit. The display size of the drawing object other than the enlargement target drawing object and the display object other than the enlargement target drawing object are controlled by the display size, so that even if any of the drawing objects is enlarged, the drawn drawing object is reduced and displayed without distortion. Therefore, it is possible to prevent a reduction in the visibility of the drawn object that is displayed in a reduced size. In addition, it is possible to further enlarge and display a drawing object that is frequently expanded, and to expect an improvement in visibility.

  Further, according to the display device of the first embodiment, the display size determination unit includes the maximum enlargement size management unit that manages the maximum enlargement size of the enlargement target drawing object, and when calculating the enlargement ratio, the display size determination unit is equal to or less than the maximum enlargement size. Since the enlargement ratio is determined so that the minimum display size is ensured for the drawing object displayed in a reduced size, the visibility of the drawing object displayed in a reduced size can be ensured.

  In the present invention, any constituent element of the embodiment can be modified or any constituent element of the embodiment can be omitted within the scope of the invention.
