Various data written in the scroll control information table 40 will be described later.

The control unit 12 further includes a scroll control information input processing unit 30 and a scroll control information calculation processing unit 31.
And a scroll control processing unit 32.

The specific configuration of the control unit 12 and the scroll control information table 40 in the memory 20 in FIG. 1 are the core of the present invention, and the configuration will be described below. In FIG. 1, the scroll control information input processing unit 30 is a unit that controls scroll control information input from the operation unit 10, and a schematic flowchart thereof is shown in FIG. In the case where an instruction related to screen scroll is given by the operation unit 10 in FIG. 2 (step 5
0) If the input instruction is from the scroll key (step 51), the scroll control processing unit 32 in FIG. 1 is called (step 52). At that time, the direction designated by the scroll key is passed as an argument.

If the input instruction is to change the fixed angle, angle designation processing (acquisition of data required for angle designation) is performed (steps 53 and 54). Here, the change of the fixed angle is an instruction to be given when the operator wants to change the angle in the fixed angle scroll which is a function of scrolling the display screen at a preset angle, and is used as an angle designation means. In this embodiment, the following three are prepared.

(1) Angle designation by numerical input.

(2) Designation from the input screen dedicated to the angle designation arranged on the diamond display screen.

(3) Designation of the angle of the representative diamond stripe.

(1) is a means for designating an angle by key input, and (2) is a means for designating an angle on a circular angle scale displayed on the display screen of the display unit 18, as shown in FIG. 3 (a). An angle designation input section in which an arrow 21 indicating a scroll angle is arranged is provided, and an operator designates an intended direction by moving the arrow with a mouse pointer, or as shown in FIG. 18 diamond display screen 2
Scroll direction designation frame (angle scale) 23 outside 4
Is provided and the operator is an angle designating means by a graphic approach such as picking the frame 23 with the mouse pointer and designating an intended direction, and by arranging it on the same screen as the diamond display screen. The intended angle can be easily determined.

In (3), the operator clicks the diamond having the angle closest to the angle the operator wants to scroll from among the diamonds on the display screen, or the diamond ID NO. It is an angle designating means by selecting by key input. The angle (tilt) of the specified diamond is calculated by the scroll control information calculation processing section 31. The operator can specify the angle by any of the above three methods.

If the input instruction is the designation of the tracking scroll mode, the tracking scroll mode registration process is performed by selecting the type of the tracking scroll and designating which diamond line is to be traced (step 5).
7, 58). Here, the tracking scroll is intended to scroll the display screen so as to follow the diamond specified by the operator, and as described above, there are the following two types.

(1) Scrolling with inclination of a specified diamond (tilt tracking scroll mode).

(2) Scroll by the boundary point of the specified diamond (boundary point tracking scroll mode).

The former is for scrolling as shown in FIG. 11, and scrolls at an inclination near the boundary on the display screen of the diamond, and the latter is for scrolling as shown in FIG. 12 on the display screen of the diamond. Scroll in the direction to move the upper boundary point to the center of the display screen.
The former has a smaller amount of scrolling movement than the latter and is effective for finely referencing the undisplayed part of the specified diamond, while the latter has a large amount of movement and allows quick reference to a specific location of the specified diamond. Yes, or it is effective scrolling when the specified diamond line from the beginning is in a place that is difficult to refer to on the display screen.

The designation of the diamond line is performed by clicking the diamond line on the display screen with the mouse pointer or by setting the NO. Is performed by the operator's key input.

If the input instruction is to cancel the tracking scroll mode of the designated diamond, the information of the portion of the scroll control information table 40 in the memory 20 related to the cancellation instruction of the tracking scroll mode is cleared (step 59). 56).

The scroll control information calculation processing unit 31 in FIG. 1 is mainly called when the angle of the fixed angle scroll is changed and the tracking scroll mode of the specified diamond is set, and the inclination of the specified diamond is calculated. Calculation processing such as calculation is performed, and the result is written in the scroll control information table 40 (steps 55, 5).
6).

Next, the processing contents of the scroll control information calculation processing section 31 will be described with reference to FIG. In the figure, when the tracking scroll mode of the specified diamond is set, the direction of the diamond, the coordinates of the boundary point between the diamond and the display screen, and the inclination of the specified diamond (length: width ratio)
Is calculated (steps 70, 71, 72). Here, for the purpose of this scroll, the inclination of the designated diamond is the inclination near the boundary on the display screen. In the calculation method, as shown in FIG. 6, the slope is calculated by the ratio of the movement amount d in the time axis direction and the movement amount h in the distance direction. Width around the border 3
3 is suitable for the amount of screen that is moved at one time by normal vertical / horizontal scrolling.

On the other hand, when this process is called in order to change the fixed angle of scroll in the fixed angle scroll mode, first, the angle designating means is determined (steps 70, 73).

In the case of direct designation of the angle, the value of the angle obtained by the angle designation process (step 54) in FIG. 2 is converted into the vertical-to-horizontal integer ratio in consideration of the actual scroll control ( Step 74).

When the fixed angle is changed by designating a representative diamond line, the average value of the inclinations of the designated diamond lines acquired by the angle designation process (step 54) in FIG. 2 is calculated (step 75).

As a method of calculating the average slope of the diamond stripes, as shown in FIG. 5, (a) the average of the diamond stripes on the display screen is calculated.

(B) Calculate the average value excluding the horizontal portion of the diamond stripe on the display screen.

Although a method such as the above is conceivable, the calculation method shown in FIG. 5 (b), which is considered to be most suitable for the actual use, is used here.

The calculation results of steps 72, 74 and 75 are written in the scroll control information table 40 in the memory 20 (step 76).

Next, the data structure of the scroll control information table 40 in FIG. 1 will be described. FIG. 7 shows the data structure of the scroll control information table 40.

This scroll control information table includes a designation presence / absence flag 40A for identifying the presence / absence of a tracking scroll mode setting of a designated diamond, a tracking type flag 40B for identifying the type of the tracking scroll mode, and a designated diamond. If the tracking scroll mode is set, the ID number of the diamond is NO. Specified diamond No. for specifying 40C, fixed angle scroll angles (length: width ratio) 40D and 40E, and designated diamond information 40F.

The angle at the time of scrolling at a fixed angle is information 4 for each direction so that it can be designated at the time of input for each of the + direction / -direction (upward direction / downward direction) with respect to the time axis.
It has 0D and 40E.

Further, the designated diamond information 40F is, for example, as shown in FIG. 10, data 80A and 80B indicating the size (aspect ratio) of inclinations 1 and 2 near the boundary between the designated diamond and the display screen, and the direction. Data 8 (representing whether the direction is + or − (up / down) with respect to the time axis)
1A, 81B, data 82A, 82 showing coordinates of boundary points
It consists of B. These pieces of information are registered in order from the smallest time axis.

The scroll control processing unit 32 in FIG.
Is the part that controls the actual scrolling process, and the processing content is shown in FIG. The operation of the sequential scroll control processing unit 32 will be described with reference to FIG.

In FIG. 8, first, the scroll direction is acquired based on the key input of the scroll key by the operation unit 10 (step 100). Here, in order to realize a fixed-angle diagonal scroll, the scroll keys are not limited to two in each of the vertical and horizontal directions, but those that point in the diagonal direction are operated by the operation unit 10.
Alternatively, the display unit 18 has four each.

Next, it is judged whether or not the tracking scroll mode of the designated diamond is currently set by referring to the scroll control information table 40 (step 101).

If the tracking scroll mode is set, the inclination of the specified diamond information or the coordinates of the boundary point is acquired from the scroll control information table 40 according to the set tracking scroll type (step 102). , 103, 104). Which of the two types of information is to be obtained from the direction of the scroll key and the direction of the slope of the already acquired scroll key when obtaining the size of the slope (aspect ratio: aspect ratio) or the coordinates of the boundary point from the specified diamond information? To judge. However, the up / down scroll key is not the operation target scroll key of the tracking scroll in consideration of a diamond line that is folded back.

When the tracking scroll mode is set, the information necessary for executing the set tracking scroll mode is provided in step 103 or step 10.
4, the data in the scroll control information table 40 is updated.
(FIG. 1) is called, the calculation result is written in the scroll control information table 40 (step 107),
The process proceeds to the next step 108.

On the other hand, if the scrolling scroll mode is not specified and the direction of the scroll key is oblique, the scroll control information table 40 is referred to according to the direction and the fixed angle scroll angle (length: width ratio) is set. The data is acquired (steps 105 and 106), and the process proceeds to step 108.

Further, there is no designation of the tracking scroll mode,
When the direction of the scroll key is vertical / horizontal, the process directly goes to step 108 (step 105).

In step 108, the scroll control instruction data is edited according to the presence / absence of the setting of the tracking scroll mode, the information acquired from the scroll control information table 40, and the direction instructed by the scroll key.
By passing the edited data to the display rectangle calculation unit 14, scrolling according to the present invention becomes possible.
