Abstract

PURPOSE:To simplify the indicating operation by selecting automatically a display part to be indicated, from plural display parts, based on an input coordinate in a single coordinate input part. CONSTITUTION:With respect to two display parts 1, 2, a coordinate input area of a coordinate input part 3 is divided in accordance with to each display part so that display parts 1, 2 are continued in this area, and a coordinate is indicated through the coordinate input part 3 and a processing part 5 by a coordinate pointer 4. For instance, in case these display parts 1, 2 consist of 640X480 picture elements, respectively, the coordinate input area is set to the number of coordinate positions of 1,280X480 and divided into two, and allocated to each display part 1, 2. In this state, a desired coordinate is inputted by the coordinate pointer 4 in the coordinate input part 3, to which of the display parts 1, 2 this input coordinate corresponds is decided automatically by the processing part 5, and the coordinate is indicated by displaying a cursor 6 on the corresponding display parts 1, 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for indicating coordinates to a plurality of display units.

[Conventional technology]

Conventionally, in order to specify coordinates for multiple display units, it is necessary to provide a coordinate input unit for each of the multiple display units and specify the coordinates separately, or to use a common coordinate input unit for multiple display units. By manually instructing which display section the coordinates input from the coordinate input section should correspond to, the coordinates were instructed while switching the correspondence with the display section. The methods for specifying coordinates here include an absolute coordinate input method in which the coordinates of the pointing location are entered using a tablet, touch panel, light pen, etc., and a relative coordinate input method in which the amount of movement of a pointing device such as a trackball or mouse is entered. There is.

[Problem that the invention seeks to solve]

However, in the former case, since a separate coordinate input section is provided, it becomes expensive, and the coordinate designation operation also needs to be performed individually, making the operation complicated. Furthermore, in the latter case, which has a common coordinate input section, it is necessary to manually instruct to which display section the input coordinates are to be assigned, so there is still a problem that the operation becomes complicated.

The present invention has been made in view of these conventional problems, and aims to provide a coordinate instruction method that allows coordinates to be specified to a plurality of display units with a simple operation and can be implemented at low cost. purpose.

[Means and operations for solving the problem] In order to achieve the above object, the present invention provides a display section to be instructed from a plurality of display sections in the processing section based on the input coordinates in the multiple coordinate input section. is automatically selected, the input coordinates are processed according to the selected display section, and the coordinates are instructed to the display section.

[Embodiment] FIG. 1 is a block diagram showing an embodiment of the present invention. In this embodiment, the coordinate input area of the coordinate input section 3 is divided for two display sections 1 and 2, corresponding to each display section, so that display sections 1 and 2 are continuous in the coordinate input area. , a coordinate pointer 4 is used to specify coordinates through a coordinate input section 3 and a processing section 5. For example, display sections 1 and 2 are each 640 x 48
In the case of 0 pixels, the coordinate input area is enlarged and shown as 2 in Figure 2, and it is divided into two as the number of coordinate positions of 1280 x 480.
Area 3a at the coordinate position of (79) is displayed on the display unit 1, and (640
,0)~(1279.

479) is assigned to the display section 2.

In this way, the desired coordinates are input using the coordinate pointer 4 in the coordinate input section 3, and the input coordinates are displayed on the display section 1.
, 2 is automatically determined by the processing unit 5, and the cursor 6 is displayed on the corresponding display unit to indicate the coordinates.

FIG. 3 is a flowchart 1 for explaining the operation in the processing section 5 in this case. The input coordinates in the coordinate input section 3 are (Xin, Yin), and the display section 1 from the processing section 5
output coordinates (Xoutl, Youtl) for display unit 2, output coordinates for display unit 2 (Xout2, Yout2
).

In the processing unit 5, first, Xin of the input coordinates is 0≦Xin<6.
40, and if 0≦Xin<640, Xoutl = Xin, Youtl = Yi
Output n and make an instruction in the display unit 1, O≦Xin<64
If it is not 0, then Xout t2= X1n-640+ Y
out2=Yin is output and indicated on the display unit 2.

Therefore, if the cursor 6 follows the movement of the coordinate pointer 4, 1, and when the cursor 6 is at the right end of the display section 1, if you move the coordinate pointer 4 further to the right on the coordinate input section 3, the cursor 6 will move It will be erased from the display section 1 and displayed on the left end of the display section 2. In this manner, the display sections 1 and 2 can be handled continuously in the coordinate input section 3.

In the embodiment described above, the coordinate input area of the coordinate input section 3 is assigned to the display sections 1 and 2, but in another embodiment of the present invention, the coordinate input area of the coordinate input section 3 is assigned to the display sections 1 and 2. 3
The processing section 5 automatically selects the display section to be assigned based on the input coordinates of a predetermined edge line of the display screen from the coordinate input section. However, if the display sections 1 and 2 each consist of 640 x 480 pixels as shown in FIG. In the same way as in the figure, move the cursor 6 using the coordinate pointer to specify the coordinates, and when the cursor 6 reaches the coordinate input section 3, that is, either the left or right edge of the display screen, the processing section 5 (see FIG. 1) ) to switch the selected display section.

FIG. 5 is a flowchart for explaining the operation of the processing section 5 in this case. The input coordinates at the coordinate input section 3 are (Xin, Yin), and the output coordinates at the processing section 5 are (
Xout, Yout), the display flag for selecting the display section 1 is set to O1, and the display flag for selecting the display section 2 is set to 1.

The processing unit 5 first determines whether Xin of the input coordinates is 0 or 639, and when Xin #0 and Xin ≠ 639, Xout = Xi is set for the display unit indicated by the display flag.
n, Yout=Yin is output to indicate the coordinates, and when Xin·0 or Xin·639, it is then determined whether the display flag is the current month or not. Here, display flag -1
When , it is rewritten to O, and when the display flag≠1, it is rewritten to 1. Next, determine whether X1n=0 or not, and
When 1n=0, this is set as 639, and Xin ≠
If it is 0, set this as O, and the rewritten Xin as Xo
Instruct ut to the display section indicated by the display flag with Yout as the input coordinate Yin.

In this way, as shown in FIG.
, move cursor 6 to the right end (639, O) to (639,
479), the display section 1 will be displayed as shown in FIG.
The cursor 6 is erased from then on, and the cursor 6 is displayed at the left end of the display section 2. Conversely, when the cursor 6 moves to the left end of the display section 1, the cursor 6 disappears from the display section 1 and is displayed at the right end of the display section 2, and when the cursor 6 moves to the left or right end of the display section 2, the display disappears. The display of the cursor 6 will move to the right or left of part 1.

In this way, according to this embodiment, the display sections 1 and 2 are automatically switched according to the instructions on the edge lines, so that the coordinate input section using the relative coordinate input method can be used in the same way as in the above-mentioned embodiment. Can be specified.

In the above embodiment, there are two display sections, but it is possible to use three or more display sections, and in the embodiment shown in FIG. 4, any of the upper, lower, left, and right sides can be used as the end lines.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to specify the coordinates of a plurality of display sections using a single coordinate input section assuming that the display sections are continuous. It also becomes easier.
