[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device having a cathode ray tube or the like, and a remote control device for controlling the display device by remote control.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a display device having a display portion such as a cathode ray tube such as a so-called personal computer device, a word processor device and a television device. The display section of these display devices is formed in a substantially rectangular flat surface shape, and can display characters, figures, etc. in a two-dimensional manner.

In such a display device,
There is a structure in which a character, a graphic or the like can be displayed at an arbitrary position on the display unit by an input operation. That is, this display device is configured to display a so-called cursor on the display unit, and to display an input character or figure at the position where the cursor exists. In this display device, the cursor can be freely moved on the display unit by a manual operation.

Manual operation for moving the cursor on the display section can be performed by using, for example, an input device having four key switches corresponding to four directions of up, down, left and right. That is, when the key switch corresponding to the upward direction is operated, the cursor moves upward on the display unit. Similarly, the cursor moves downward on the display by operating the key switch corresponding to the downward direction, and moves leftward on the display by pressing the key switch corresponding to the left direction, and then moves to the right. If the key switch corresponding to the direction is operated, it moves to the right on the display unit.

In order to perform the manual operation for moving the cursor on the display unit more smoothly and quickly, a two-dimensional input device called a joystick, a trackball, or a mouse has been proposed.

The joystick detects an operating rod which is rotatably supported on the base end side, and a rotational direction and a rotational angle of the operating rod, that is, a vector amount corresponding to the rotation of the operating rod. And a detection mechanism. The operating rod is supported so that it can be tilted in all peripheral directions from the center position. That is, the tip of this operating rod is movable in two dimensions.
The trackball and the mouse each include a rotatably supported sphere and a detection mechanism that detects a vector amount corresponding to the rotation of the sphere.

The detection mechanism in these two-dimensional input devices detects a rotation component in one direction and a component in another direction orthogonal to the one direction in the rotation or rotation of the operating rod or the sphere. , Separate, detect, and output as an electrical signal. That is, the detection mechanism represents the x component and y when the vector amount corresponding to the rotation or rotation of the operation rod or the sphere is expressed on the xy coordinates.
The component is detected and output as an electric signal. The x component of the vector amount detected by this detection mechanism corresponds to the amount of vertical movement of the cursor on the display unit. Further, the y component of the vector amount detected by the detection mechanism corresponds to the amount of horizontal movement of the cursor on the display unit.

In the display device having such a two-dimensional input device, the cursor is freely moved in any direction on the display unit by rotating or rotating the operation rod or the sphere. be able to.

On the other hand, in the display device as described above,
It has been proposed that the cursor moving operation and other operations can be performed via a remote control device for controlling a display device, a so-called remote controller device. Such a remote controller device is configured to have the two-dimensional input device and other key switches, etc., and outputs an operation signal corresponding to a manual operation to the two-dimensional input device and each key switch to a microwave, an infrared ray, or the like. Is superposed on a carrier wave such as an electromagnetic wave or an ultrasonic wave and transmitted as a remote control signal to the main body side of the display device. A receiving circuit that receives the remote control signal and demodulates it into the control signal is provided on the main body side of the display device. In this display device, various operations such as the movement of the cursor are performed according to the operation signal received and demodulated by the receiving circuit.

That is, it is difficult for the cursor to move along a straight line, and even if the cursor is moved along a straight line, it is often moved in a fine wavy trajectory.

This is because the rotating or rotating operation of the operating rod or the spherical body is performed by fingers or the like, and the vibration of the fingers or the like propagates to the operating rod or the spherical body.
This is also because it is difficult for the fingers or the like to always rotate or rotate the operating rod or the spherical body in a fixed direction.

If the cursor cannot be moved so as to follow a straight line on the display unit, when the character or figure is displayed on the display unit with a fine pitch, the cursor is moved. It may be difficult to move it to a desired position.

Therefore, the present invention is proposed in view of the above-mentioned circumstances, and the cursor displayed on the display unit is manually operated by using a two-dimensional input device such as a so-called joystick, trackball or mouse. It is an object of the present invention to provide a display device and a remote control device for controlling the display device, which are capable of moving the cursor by accurately following a straight line when the cursor is moved by an operation.

Based on the received operation signal, the position detecting means calculates a movement amount signal indicating the direction and amount of movement, and the movement amount signal has the movement direction indicated by the movement amount signal set in advance by the signal processing means. When it is within the angle range, it is converted into a cursor control signal indicating movement in one direction within the angle range. Then, the control means determines the display position of the cursor on the display means based on the cursor control signal and causes the display means to display.

In this case, the cursor on the display means can be moved in one direction within a preset angle range by the remote operation device.

In the remote control device for controlling a display device according to the present invention, when the cursor movement operation means is operated, an operation signal corresponding to the direction and amount of movement on the two-dimensional coordinates is output in response to this operation. A position detection means calculates a movement amount signal indicating a movement direction and an amount based on the operation signal, and the movement amount signal indicates a movement direction indicated by the movement amount signal by the signal processing means. If it is within the range, it is converted into a cursor control signal indicating movement in one direction within the angle range. Then, the cursor control signal is transmitted by the transmitting means as a remote control signal to a display device having a control means for determining the display position of the cursor on the display means based on the cursor control signal and displaying the cursor on the display means. To be done.

In this case, the cursor on the display means of the display device can be moved in one direction within a preset angle range by remote control.

In the display device and the remote control device for controlling the display device, the conversion of the movement amount signal by the signal processing means is set by dividing the entire circumference into eight parts.
To the cursor control signal indicating movement in one direction within the angle range including the movement direction indicated by the movement amount signal, the display means The movement of the cursor in can be performed in one direction in any of the first to eighth angular ranges, that is, in any of the eight directions.

That is, according to the present invention, when the cursor displayed on the display unit is moved manually by using a two-dimensional input device such as a so-called joystick, trackball or mouse, the cursor is accurately aligned with a straight line. It is possible to provide a display device and a remote control device for controlling the display device that can be traced and moved.
