METHOD FOR SENSING MOTION AND DEVICE FOR IMPLEMENTING THE SAME
First Claim
1. A method for sensing a motion of an object, said method to be implemented by a motion recognition device that includes an image acquiring unit and a processor, and comprising the following steps of:
- a) configuring the image acquiring unit to acquire continuously a series of image frames by detecting intensity of light received thereby;
b) configuring the processor to receive at least one of the image frames and to determine whether an object is detected in said at least one of the image frames; and
c) when the determination made in step b) is affirmative, configuring the processor to receive the image frames from the image acquiring unit, and to determine a motion of the object with respect to a three-dimensional coordinate system according to the image frames thus received.

Abstract
A method for sensing a motion of an object is to be implemented by a motion recognition device that includes an image acquiring unit and a processor. In the method, the image acquiring unit is configured to acquire a series of image frames by detecting intensity of light received thereby. The processor is configured to receive at least one of the image frames and to determine whether an object is detected in the at least one of the image frames. When an object is detected, the processor is further configured to receive the image frames from the image acquiring unit, and to determine a motion of the object with respect to a three-dimensional coordinate system according to the image frames thus received.

13. A motion recognition device comprising:
-
an image acquiring unit including a photodetector array and an analog-to-digital converter (ADC), said photodetector array including a plurality of photodetectors arranged on a two-dimensional plane and being operable to generate sense signals by detecting intensity of light received thereby, said ADC being coupled to said photodetector array for receiving the sense signals therefrom and being operable to convert the sense signals into image frames; and a processor coupled to said ADC of said image acquiring unit and operable to determine whether an object is detected in at least one of the image frames and, when the determination is affirmative, to determine a motion of the object with respect to a three-dimensional coordinate system according to apart of the image frames that are acquired after acquisition of said at least one of the image frames where the object is detected. - View Dependent Claims (14, 15, 16, 17)
