Abstract

Disclosed are a remote controller, a remote controlling method, and a display system having the same. An image displayed on a display apparatus may be converted by using one remote controller. The display system may perform a converting the image by using one remote controller, without implementing a touch screen on the display apparatus or using two or more remote controllers for multi-touch. This may enhance a user'"'"'s convenience and reduce fabrication costs.

Claims

1. A remote controller for remote-controlling a display apparatus, the remote controller comprising:

a motion detection unit having one or more sensors and the motion detection unit configured to detect a motion of the remote controller;

a control unit configured to generate a control signal for converting an image displayed on the display apparatus based on the motion of the remote controller detected by the motion detection unit, wherein the converting the image is zooming or rotating of the image; and

a communication unit configured to transmit the control signal to the display apparatus.

2. The remote controller of claim 1, further comprising a storage unit configured to store driving programs for the remote controller, and control commands for a converting the image in correspondence to a motion of the remote controller,

wherein the control unit extracts a control command corresponding to the motion detected by the motion detection unit among the control commands stored in the storage unit, and generates a control signal including the extracted control command.

4. The remote controller of claim 1, further comprising a storage unit configured to store driving programs for the remote controller, and control commands for a converting the image in correspondence to a motion of the remote controller,

wherein the remote controller enters an image conversion mode or returns to a previous mode by detecting a pressed state of the mode conversion button.

6. The remote controller of claim 4, wherein the control unit is configured to generate a control signal when the mode conversion button is in a pressed state, and to transmit the control signal to the display apparatus through the communication unit.

7. The remote controller of claim 1, wherein the control unit is configured to generate a control signal when the remote controller in a preset posture is moved, and to transmit the control signal to the display apparatus through the communication unit.

8. The remote controller of claim 1, wherein the control unit performs a converting the image by using at least one of a speed, a distance and a direction of the remote controller, and

wherein the control unit determines a range of converting the image based on at least one of a speed, a distance and a direction of the remote controller.

10. The remote controller of claim 8, wherein the motion detection unit repeatedly detects a motion of the remote controller, and the control unit performs a converting the image based on the detected motion and the number of times.

11. The remote controller of claim 1, wherein the converting the image further includes at least one of enlargement, reduction, and rotation of the image based on a certain center point of the image, moving the center point, and scroll or drag of the image, and

wherein the center point is a cursor point when the remote controller points a specific position.

13. The remote controller of claim 1, wherein the motion detection unit comprises at least one of one or more gyro sensors, one or more acceleration sensors, one or more terrestrial magnetic sensors, and one or more distance sensors.

14. The remote controller of claim 13, wherein the motion detection unit detects a three-dimensional motion of the remote controller by combining at least one or two of the gyro sensor, the acceleration sensor, the terrestrial magnetic sensor and the distance sensor with each other.

15. A remote controlling method for remote-controlling a display apparatus by using a remote controller, the method comprising:

detecting a motion of the remote controller by the remote controller;

generating a control signal for converting an image displayed on the display apparatus based on the motion of the remote controller detected by the motion detection unit, wherein the converting the image is zooming or rotating of the image; and

transmitting the control signal to the display apparatus.

16. The method of claim 15, further comprising converting a current mode into an image conversion mode for performing the converting the image.

17. The method of claim 16, wherein the converting a current mode into an image conversion mode comprises:

detecting a pressed state of a mode conversion button provided at the remote controller; and

entering the image conversion mode or returning to a previous mode when the mode conversion button is in a pressed state.

19. The method of claim 16, wherein the converting a current mode into an image conversion mode comprises determining whether the remote controller in a preset posture is moved,

wherein when the remote controller in a preset posture is moved, the current mode is converted into the image conversion mode.

20. The method of claim 17, wherein the converting a current mode into an image conversion mode further comprises:

generating a control signal to display directions of the converting the image or a center point and the directions of the converting the image on the display apparatus; and

transmitting the control signal to the display apparatus.

23. The method of claim 15, further comprising performing the converting the image based on the control signal by the display apparatus,

wherein the performing the converting the image comprises:

detecting information on a speed, a distance and a direction of the remote controller from a detected motion; and

determining a range of the conversions based on at least one of the speed, the distance and the direction.

26. A display system, comprising:

a remote controller configured to detect its own motion, and to generate a control signal corresponding to the detected motion; and

a display apparatus configured to convert an image displayed on a screen based on the control signal, wherein the converting the image is zooming or rotating of the image.

27. The display system of claim 26, wherein the remote controller comprises:

a motion detection unit provided with at least one of one or more gyro sensors for detecting rotation of the remote controller, one or more acceleration sensors for detecting acceleration of the remote controller, one or more terrestrial magnetic sensors, and one or more distance sensors, and the motion detection unit configured to detect a motion of the remote controller;

a control unit configured to generate a control signal for converting an image displayed on the display apparatus in correspondence to the motion detected by the motion detection unit; and

a communication unit configured to transmit the control signal to the display apparatus.

29. The display system of claim 27, wherein the remote controller further comprises a mode conversion button configured to allow the remote controller to enter an image conversion mode for performing a converting the image.

33. The display system of claim 26, wherein the display apparatus extracts a control command from the control signal, and displays a center point or a direction of the converting the image according to the control command, or displays the center point and the direction together.
