Description of the Invention: [Technical Field] The present invention relates to a computer input system, and more particularly to a computer input system for sensing a point light source using an imaging device. [Prior Art] [0002] In addition to using a keyboard as an input device for a computer, a mouse is used as an input device to input an instruction or data. By detecting the position of the mouse and executing the corresponding driver software, the movement and input operation of the _ mouse cursor on the monitor is achieved by pressing the left and right mouse buttons. In addition, by using the recognition software, the handwriting input device can also be executed. Therefore, the use of computers has become easier. [0003] However, conventional input devices are not satisfactory, for example, the cable connecting the mouse is confusing, and the mouse can only be operated on the mouse pad or on a flat surface. Furthermore, the use of a mouse as a handwriting input device is considered to be inconvenient. [0004] Due to the increasing popularity of multimedia applications, audio/video devices, such as video cameras, have been used on computers. If you only use a video camera to make a simple camera device, it may become a redundant device on the computer with the development of science and technology. SUMMARY OF THE INVENTION [0005] In view of the above, it is necessary to provide a computer input system that utilizes a camera device to sense a point source to implement handwriting input and point operations. [0006] A computer input system includes a monitor, the computer input system comprising: a light emitting device that is movable and emits infrared light and 098124814 Form No. A0101 Page 3 / Total 12 Page 0982422384-0 201104511 a different color of the bebeben. A camera device disposed inside the monitor to receive infrared rays emitted by the illumination device to capture the motion of the illumination device, and to ingest the illumination device Feeding and identifying the seam; the data transfer unit, wherein the camera device receives the motion track of the light device to display the track of the light device on the monitor and according to the color of the visible light Perform a point operation. [0009] [0009] [0010] 098124814 Compared with the prior art, the present invention "applied computer input system uses the camera device to sense the county of the point source; and displays the job to realize the handwriting input function; In addition, the visible colors of different colors first represent different point operations 'the imaging device realizes the point operation by the visible light emitted by the illuminating device. ''The second embodiment of the present invention will be further described in detail below with reference to the accompanying drawings. i, FIG. 2 and FIG. 3, the computer input system 10 of the fifth embodiment of the present invention uses a camera device to sense a point light source to implement a handwriting input function and a point operation, which includes a monitor U and a camera device 12 (with an image sensor inside, image The sensor 11 is a light-emitting device 13 and a data processing unit 14 as a point wheeling device. The monitor 11 has a receiving hole 111, and the camera device 2 is located in the receiving hole. The monitor 11 can be a CRT (cathode ray tube, a cathode ray tube) display or an LCD (liquid crystal diSpUy) display. The optical axis of the camera 12 is denoted by 〇〇', which is used to detect hair The motion trajectory of the device 13 is to implement a handwriting input operation to the monitor u. Form No. A0101 Page 4 / Total 12 Page 0982042384-0 201104511 [0011] When the computer is used to input the system 10, the monitor 11 is placed on the desktop 20. The normal line of the table top 20 is denoted by L, and the angle a between the optical axis 00' and the normal L is greater than or equal to 0 degrees and less than 90 degrees, preferably 0 degrees, that is, the optical axis 00' parallel normal L. If the optical axis 00' is not parallel to the normal L, the image captured by the camera 12 will have a trapezoidal deformation, and the data processing unit 14 is required to correct the obtained image; if the optical axis 00' is parallel to the normal L, trapezoidal deformation does not occur, but since the shooting range is on the same side of the optical axis 00', in order to have a larger shooting range, the imaging device 12 needs to have a larger viewing angle. ❹ The light-emitting device 13 is preferably a pen. The shape is convenient for the user to hold, and includes a pen stalk 130, a power source 131 located inside the pen holder 130, and a light source 132 at the end of the pen holder 130. The light source 132 can emit infrared light and two different colors of visible light, including an infrared light source. 1321 The first visible light source 1 322 and the second visible light source 1323, the infrared light source 1321 are connected to the power source 131 through the micro-touch switch 133, and the first visible light source 1 322 and the second visible light source 13 2 3 pass through the first switch 13 4 , respectively. The first switch 135 and the second visible light source 1 323 can be blue and green, blue and red, or green and blue. [0013] When the light-emitting device 13 contacts the table top 20, the micro-touch switch 133 is turned on with the power source 131 such that the infrared light source 1321 emits infrared light; when the light-emitting device 13 leaves the table top 20, the micro-touch switch 133 is disconnected from the power source 131 such that the light-emitting device 13 no infrared light is emitted. When the first switch 134 is pressed, the first visible light source 1322 emits the first visible light; when the second switch 135 is pressed, the second visible light source 098124814 Form No. A0101 Page 5 / Total 12 pages 098442384-0 201104511 1323 emits flute _ visible light . The camera 12 senses and recognizes the color of the visible light emitted by the illumination device 13 and inputs the information to the data processing unit 14 to perform the functions of the left and right mouse-like keys. At this time, the illumination device 13 has a mouse. The function here defines the first - visible light & «left button, the second visible light represents the right mouse button. [0016] [0016] In use. When the computer enters the system 1 ' 'If the computer input system 1 〇 needs to implement the handwriting round function, the camera 12 turns on and points to the desktop 20 where the monitor 11 is located. 'The light-emitting device 13 is placed in the shooting range of the camera (10). The lower infrared light source 1321 emits infrared light, and the moving light-emitting device 13' camera device 12>f detects the movement trajectory of the light-emitting device 13 (for example, a cross-shaped track) and inputs the information to the data processing unit 14' the bedding processing unit 14 The information is processed and the red-turned track is not displayed on the monitor 11 to realize the handwriting input function _, and when the computer wheeling system 1 () needs to realize the point operation of the left mouse button win, pressing the first switch 134 causes The illuminating device 13 emits the first visible light, and the imaging device 12 senses that it is the first visible light and inputs it to the data processing unit 14, thereby performing the left button function of the mouse, thereby realizing the point operation; when the right mouse button function needs to be executed Press the second switch 135 to emit the second visible light. In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
