Abstract

PURPOSE:To comprise a panel controller of a coordinate input part with resolution less than the display capacity of a display part and to miniaturize the coordinate input part by transforming coordinates inputted to the coordinate input part to the one in an operating area registered at a panel registration part. CONSTITUTION:The operating area is registered on the panel registration part 101 by an application program with a display area and display data. A panel display part 103 displays the display data registered at the panel registration part 101 on the area on the display part 102 equivalent to the display area registered at the panel registration part 101. A coordinate transformation part 105 transforms the coordinates inputted to the coordinate input part 104 to the one in the operating area registered on the coordinate registration part 101. A cursor display part 106 displays a cursor at a position on the display part 102 equivalent to the coordinates transformed at the coordinate transformation part 105. Thereby, it is possible to comprise the panel controller of the coordinate input part with resolution less than the display capacity of the display part.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel control method and apparatus for allowing a user to selectively input a command in a computer system or a television receiver.

[0002]

2. Description of the Related Art In the field of computer systems, a GUI is widely used in which a user executes a command by pointing a character or figure displayed on a display with a pointing device such as a mouse. Since the user can easily use complicated functions by using the GUI, the GUI is being used in devices such as a television receiver in recent years.

As a method for realizing a GUI, there is a panel control device in which a panel including a message or the like is displayed on a display and a user selects a character or a graphic in the panel with a pointing device to input a command.

A conventional panel control device will be described below. FIG. 5 is a block diagram of a conventional panel control device. In the figure, reference numeral 501 denotes a panel registration unit, in which a display area and display data are registered by an application program. 502
Is a display unit, which is realized by a cathode ray tube and a video RAM. A panel display unit 503 displays the display data registered by the panel registration unit 501 in an area on the display unit 502 corresponding to the display area registered by the panel registration unit 501. A coordinate input unit 504 is realized by a pointing device such as a digitizer or a touch panel. A cursor display unit 505 displays a cursor at a position on the display unit 502 corresponding to the coordinates input by the coordinate input unit 504.

The operation of the panel control device configured as described above will be described below with reference to FIG. Figure 6
(A) is a display area A registered in the panel registration unit 501.
And an example of display data D. The display unit 502 has a display capacity of 640 horizontal dots and 400 vertical dots, and 0 ≦
It is assumed that the display position is designated by the coordinates (X, Y) such that X ≦ 639, 0 ≦ Y ≦ 399. Coordinate input unit 504
Has a resolution of 640 horizontal dots and 400 vertical dots, and 0 ≦
It is assumed that the coordinates (X, Y) satisfying X ≦ 639, 0 ≦ Y ≦ 399 are input. (1) The application program is the panel registration unit 50
The display area A and the display data D are registered in 1. (2) The panel display unit 503 displays the display data D in the area corresponding to the display area A on the display unit 502.
As a result, a panel as shown in FIG. 6B is displayed on the display unit 502. (3) The user inputs the coordinate P1 to the coordinate input unit 504. It is assumed that the input coordinate P1 is (320, 200). (4) The cursor display unit 505 displays the cursor on the display unit 502 at a position corresponding to the coordinate P1. As a result, a cursor as shown in FIG. 6B is displayed on the display unit 502. (5) When the user inputs a new coordinate P2 to the coordinate input section 504, the cursor display section 505 changes the display section 50.
The cursor at the coordinate P1 of 2 is deleted, and the coordinate P2 is newly added.
Display the cursor on. As a result, the display unit 50
At 2, the cursor moves from the coordinate P1 to the coordinate P2.

An actual panel control device requires, in addition to the above configuration and operation, components and operations for instructing confirmation of selection of characters and figures in the panel, but this is omitted because it is not the main subject of the present invention. To do.

[0007]

However, in the above-mentioned conventional configuration, in order to display the cursor at an arbitrary position in an arbitrary panel, the coordinate input unit 504 has a display capability equal to or higher than that of the display unit 502. Since it must have resolution, the coordinate input unit 5 with high resolution can be used even when only a part of the panel is indicated by the cursor.
There was a problem that 04 had to be prepared.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a panel control device that can be configured with a coordinate input section having a resolution lower than the display capability of the display section. ..

[0009]

In order to achieve this object, a panel control device of the present invention has a panel registration section for registering an operation area together with a display area and display data, a display section, and registration in the panel registration section. A panel display unit that displays the display data registered in the panel registration unit in a region on the display unit corresponding to the displayed display region, and a coordinate input unit in which the user inputs two-dimensional coordinates.
A coordinate conversion unit that converts the coordinates input in the coordinate input unit into coordinates in the operation area registered in the panel registration unit, and a position on the display unit corresponding to the coordinates converted in the coordinate conversion unit. It has a configuration of a cursor display section (or a highlight display section that highlights an area including coordinates converted by the coordinate conversion section in the display data displayed by the panel display section) that displays a cursor. There is.

[0010]

With this configuration, when the area to be designated in the panel is registered as the operation area in the panel registration section, the coordinates input in the coordinate input section are converted into the coordinates in the operation area by the coordinate conversion section, and the cursor is converted. A cursor can be displayed at the converted coordinates on the display unit (or a portion located at the converted coordinates on the highlight display unit can be highlighted).
