Abstract

An exercise device includes one or more image-capturing units, two identity backgrounds, and a processing unit. Each image-capturing unit captures images of one corresponded identity background shaded by a user, and the processing unit analyzes the captured images in real time, so as to automatically control the exercise device.

First claim

What is claimed is:

1. An exercise device, comprising:
a belt on which a user walks or runs in place;
two identity backgrounds being respectively arranged at a left side and a right side of the belt;
at least one image-capturing unit facing the belt and the two identity backgrounds for capturing images of two identity backgrounds shaded by the user; and
a processing unit connected with the at least one image-capturing unit for analyzing the captured images so as to obtain a variation of the user's position and thus control the exercise device according to the variation of the user's position.

2. The exercise device as set forth in claim 1 , wherein the processing unit obtains the variation of the user's position by analyzing a variation of grayscale of the captured images.

3. The exercise device as set forth in claim 1 , wherein each of the two identity backgrounds comprises one or more light sources.

4. The exercise device as set forth in claim 1 , wherein each of the two identity backgrounds comprises a reflector.

5. The exercise device as set forth in claim 4 , further comprising two light sources, wherein each of the two light sources corresponds to one of the two reflectors and emits a light to the corresponded reflector.

6. The exercise device as set forth in claim 1 , wherein the two identity backgrounds are respectively arranged at a left side edge and a right side edge of the belt.

7. The exercise device as set forth in claim 1 , further comprising two decorating bars respectively arranged at a left side and a right side of the belt, and wherein the two identity backgrounds are respectively arranged at a side of one decorating bar.

8. The exercise device as set forth in claim 1 , further comprising a left post and right post respectively arranged near a left front corner and a right front corner of the belt, and wherein there are two image-capturing units, and the two image-capturing units are respectively arranged at the left post and the right post.

9. The exercise device as set forth in claim 8 , wherein if two shaded areas are observed in an image captured by the two image-capturing units, one of the two shaded areas close to the front of the belt will be analyzed and the other of the two shaded areas close to the rear of the belt will be ignored.

10. The exercise device as set forth in claim 1 , wherein there are two image-capturing units, and the two image-capturing units are arranged in a middle portion in front of the belt for respectively capturing images of the opposite corresponded identity background.

11. The exercise device as set forth in claim 1 , wherein the number of the at least one image-capturing unit is one, and the image-capturing unit is arranged on a middle portion of a housing in front of the belt for simultaneously capturing images of the two identity backgrounds.

12. The exercise device as set forth in claim 1 , wherein the belt comprises a speeding zone, a normal zone, and a slowing zone, and when more than a predetermined percentage of the user's paces is within the speeding zone during a predetermined period of time, then the processing unit increases the rotational speed of the belt; when more than the predetermined percentage of the user's paces is within the normal zone during a predetermined period of time, then the rotational speed of the belt is not varied; and when more than the predetermined percentage of the user's paces is within the slowing zone during a predetermined period of time, then the processing unit decreases the rotational speed of the belt.

13. The exercise device as set forth in claim 1 , wherein the belt comprises an ascending zone and a descending zone, and when more than a predetermined percentage of the user's paces is within the ascending zone during a predetermined period of time, then the processing unit increases an incline angle of the belt; when more than the predetermined percentage of the user's paces is within the descending zone during the predetermined period of time, then the processing unit decreases the incline angle of the belt.

14. An exercise device, comprising:
a belt on which a user walks or runs in place;
an identity background being arranged on a middle portion of the belt;
at least two image-capturing units facing the belt and the identity background for capturing images of the identity background shaded by the user; and
a processing unit for analyzing the captured images so as to obtain a variation of the user's position and thus control the exercise device according to the variation of the user's position.

15. The exercise device as set forth in claim 14 , wherein the processing unit obtains the variation of the user's position by analyzing a variation of grayscale of the captured images.

16. The exercise device as set forth in claim 14 , wherein the identity background comprises one or more light sources.

17. The exercise device as set forth in claim 14 , wherein the identity background comprises a reflector.

18. The exercise device as set forth in claim 17 , further comprising at least one light source, and wherein the at least one light source emits a light to the reflector.
