CONTROL APPARATUS AND METHOD
First Claim
1. A control apparatus for providing a user with a control over an object displayed in a display apparatus by a pointing device, the control apparatus comprising:
- an image capturing module for recording a video sequence and generating N image frames, N being a positive integer;
a separating module for capturing a pointing device image related to the pointing device from each image frame in accordance with a characteristic of the pointing device;
a positioning module for calculating a specific point of the pointing device image of each image frame to generate a first set of specific point information;
a constructing module for generating a trajectory in accordance with a pre-defined criterion and the first set of specific point information; and
a processing module for analyzing the trajectory and generating a control signal to control the object.

Abstract
The invention discloses a control apparatus capable of providing a user with a control over an object displayed on a display apparatus by a pointing device. The control apparatus includes an image capturing module, a separating module, a positioning module, a constructing module, and a processing module. The image capturing module is used to record an image sequence included N images. The separating module is applied to capture the pointing device image related to the pointing device from each image. The positioning module is used for calculating a specific point of the pointing device image of each image to generate a first set of specific point information. The constructing module is applied to generate a trajectory in accordance with a pre-defined criterion and the first set of specific point information. Additionally, the processing module is used to analyze the trajectory and generate a control signal to control the object.
