The hatching is displayed in a mode display to reduce its transparency as a characteristic of the background color.

After step S152, the operator station 8 initializes the counter n indicating the number of regions of interest to 1 (step S153).

Next, when the input unit 31 receives the selection input of the nth attention area (step S154: Yes), the operator station 3 moves to step S155. In the fourth embodiment, the selection input operation for enlarging the display target area is realized by the drag operation of the mouse. This drag operation is the same as that performed when, for example, a window area to be displayed on a display monitor provided in a general personal computer is enlarged. If the mouse is dragged, the area of interest is defined as a rectangular area with the start and end points of the mouse pointer as the diagonal.

The attention area setting unit 361 performs setting of the nth attention area in the trend screen based on the selection input of the nth attention area received by the input unit 31 (step S155), and temporarily stores the set information. There is a region of interest information storage unit 372.

Next, the attention area display screen generating unit 352 refers to the attention area information storage unit 372, and restores the characteristics of the background color of the set attention area to the original shape, thereby generating the entire attention area display screen data (step S156).

Thereafter, the display control unit 362 causes the display unit 34 to display the entire region of interest display screen corresponding to the entire region of interest display screen data (step S157). FIG. 39 is a view showing a display example (first example) of the all-interest area display screen. The all-interest area display screen 603 shown in the figure is displayed in the trend display area 613, and the first attention area 613a is displayed with the background color having the same characteristics as the trend screen 601. On the other hand, the non-interest area 613b has The background color having the same characteristics as the background color characteristic change screen 602 is displayed. In FIG. 39, the user sets the region of interest by dragging the mouse from the upper left vertex (see FIG. 38) to the lower right vertex of the first region of interest 613a (refer to the first region of interest 613a). Dotted arrow L). The arrow L indicates an imaginary line of the trajectory of the mouse pointer M from the background color characteristic change screen 602 of FIG. 38 to the all-interest area display screen 603 of FIG. 39, and is not displayed on the actual screen.

The magnification of the first region of interest 613a and the second region of interest 613c at this time is as described above, and the magnification in the lateral direction is larger than the magnification in the vertical direction.

After the input unit 31 receives the input of the scrolling operation of the enlargement trend screen (step S137: Yes), the display control unit 362 changes (scrolls) the portion displayed in accordance with the scroll amount and displays it on the display unit 34 (step S138). ). Fig. 42 is a view showing a display example (second example) of the enlargement trend screen in accordance with the scroll amount. The enlargement trend screen 606 shown in the figure shows that the first attention area 613a is displayed, and the vertical scroll 617a is used to roll up the animation surface. On the other hand, the horizontal scroll 618a is used, the animation surface is scrolled to the right, and the second attention area is used. 613c, using the vertical reel 617b, the animation surface is rolled up, and on the other hand, the horizontal reel 618b is used, and the display example after the animation surface is scrolled to the right. In the enlargement trend screen 606, the first attention area 613a and The characteristics of the background color of the second attention area 613c and the non-interest area 613d are the same as the all-interest area display screen 604. Therefore, when the user scrolls the enlargement trend screen, the boundary between the first attention area 613a and the second attention area 613c and the non-attention area 613d can be accurately grasped.

Next, when the input unit 31 receives the input of the reduction instruction (step S139: Yes), the operator station 3 returns to step S131.

In step S139, when the input unit 31 does not accept the input of the reduced display (step S139: No), when the input of the instruction signal for the end of the trend display is received (step S140: Yes), the operator station 3 ends the trend screen display. deal with. On the other hand, if the input unit 31 does not accept the input of the instruction signal indicating the end of the trend display (step S140: No), the operator station 3 returns to step S137.

In step S133, if the input unit 31 does not receive the input of the start instruction signal for the enlargement processing (step S133: No), and if the enlargement trend screen data is not generated in step S135 (step S135: No), the control unit 36 It is judged whether or not the state information stored in the state information storage unit 371 is updated (step S141). As a result of the determination, if the status information is updated (step S141: Yes), the operator station 3 returns to step S131. On the other hand, if the status information is not updated (step S141: No), the operator station 3 moves to step S142. The processing of step S142 is the same as that of step S9 of Fig. 4 described in the first embodiment.
