Description:
FIELD OF THE INVENTION 
       [0001]    This invention relates to a hair-cutting system, and more particularly to a hair-cutting system or hair clipper with a visualization capability. 
       BACKGROUND OF THE INVENTION 
       [0002]    Electric hair clippers or trimmer are commonly used by stylists, barbers, or individuals for styling the hair of others. However, it is needed to provide a hair-cutting system or clipper (interchangeable here) designed specifically for self-cutting. One such self-cutting electric hair-cutting clipper (e.g., commonly-assigned U.S. Pat. No. 7,281,461, to McCambridge et al, issued on Oct. 16, 2007, and incorporated by reference herein) provides effective guiding of hair into or retaining of hairs in a cutting zone of a bladeset and easy holding capability of a hair clippers. However, &#39;461 patent does not provide visualization capability. Although with helping of mirror a person can see partially his or her hair during self-cutting process, it is difficult to cut and style his or her hair on the backside and the top of his or her head. To address this problem, this is a need for improving visualization capability of a hair-cutting clipper. 
       SUMMARY OF THE INVENTION 
       [0003]    To address the needs described above, the present invention disclosed a hair-cutting system with a visualization device that includes a video camera and a lighting device attached to an electrical hair-cutting clipper. More specifically, said hair-cutting system includes at least one video camera, at least one display device, at least one hair-cutting clipper, at least one video-device-holder which holds said video camera and said hair-cutting clipper together. Such hair-cutting systems are designed for use by an individual in cutting his or her own hair, and also for use by one person to cut the hair of another. 
         [0004]    One can use the hair-cutting system proposed in present disclosure during his/her self haircutting, as shown in  FIG. 1 , especially cutting the hair he/she usually cannot see from a mirror such as the hair on the backside or the top of his/her head. For example, one activates the video camera and the display in present disclosure by plugging them into electrical power outlets and then connects the video camera with the display so that the pictures taken by the video camera can be shown on the display. When he or she is cutting his or her hair, the video camera is taking video or pictures at the same time. He/she can see the video or pictures from the display in his/her front, which can help him/her to create hairstyle that he/she wants.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0010]    Hair-cutting systems with visualization devices are disclosed. One can use the hair-cutting systems to cuts his/her own hair. He or she can use the visualization devices to watch a video or pictures in the area where usually cannot be seen when he or she cuts his/her own hair such as the backside or the top of his or her head. It is very helpful for a person who wants to get hair cut and to create any hairstyle by his or her own and improve hair cut quality. It is also useful for a customer to monitor his/her hairstyle when he or she gets a hair cut from a barber. 
         [0011]      FIG. 1  is a schematic for using a haircutting system. One can use the haircutting system proposed in present disclosure to cut his/her own hair, especially cutting the hair he or she cannot see from a mirror such as the hair on the backside or the top of his or her head. For example, one connects the video camera with a display so that the video or pictures taken by the video camera can be shown on the display. When he/she is cutting his/her own hair, the video camera takes video or pictures at the same time. He/she can see the video or pictures from the display in his/her front, which can help him/her to create hairstyle that he/she wants or improve hair cut quality.
