Treadmill and control method for controlling the treadmill belt thereof

Abstract

A treadmill and a control method for controlling the treadmill belt thereof are provided. The treadmill includes a treadmill belt, a first sensor, an image sensor, and a controller. The first sensor retrieves a light pattern or the image sensor measures the characteristic properties of the image of the user so as to control the treadmill belt. The light pattern can be generated by a signal member, which can be disposed on a side or both sides of the treadmill belt.

What is claimed is: 
     
         1 . A treadmill comprising:
 a treadmill belt;   an image sensor including an image sensing unit for retrieving an image of a user; and   a controller electrically connected to the image sensor, wherein the controller adjusts an operating speed of the treadmill belt according to the percentage of the pixels representing the user in all the pixels of the image.   
     
     
         2 . The treadmill according to  claim 1 , wherein the controller decreases the operating speed of the treadmill belt when the percentage of the pixels representing the user in all the pixels of the image is greater than a predetermined value. 
     
     
         3 . The treadmill according to  claim 1 , wherein the controller increases the operating speed of the treadmill belt when the percentage of the pixels representing the user in all the pixels of the image is smaller than a predetermined value. 
     
     
         4 . The treadmill according to  claim 1 , wherein the controller decreases the operating speed of the treadmill belt when the percentage of the pixels representing the user in all the pixels of the image decreases. 
     
     
         5 . The treadmill according to  claim 1 , wherein the controller increases the operating speed of the treadmill belt when the percentage of the pixels representing the user in all the pixels of the image increases. 
     
     
         6 . The treadmill according to  claim 1 , wherein the controller starts the operation of the treadmill belt when the percentage of the pixels representing the user in all the pixels of the image is greater than a predetermined value. 
     
     
         7 . The treadmill according to  claim 1 , wherein the controller stops the operation of the treadmill belt when the percentage of the pixels representing the user in all the pixels of the image is smaller than a predetermined value. 
     
     
         8 . The treadmill according to  claim 1 , wherein the controller determines whether the user is in the first detection area or the second detection area of the treadmill belt according to the position of the user in the image. 
     
     
         9 . A treadmill comprising:
 a treadmill belt;   an image sensor including an image sensing unit for retrieving an image of a user; and   a controller electrically connected to the image sensor, wherein the controller performs at least one of a startup operation, a shutdown operation, a speed-up operation, and a slow-down operation according to at least one gesture image corresponding to at least one gestures made by the user.
