Device)微鏡片反射技術，並採用色輪（ Color Wheel)來完成對色彩的分離和處理。 [0003] 在DMD投影系統中，光源發出的白光通過聚焦透鏡聚焦在 色輪上，色輪主要是由紅、綠、藍等彩色濾光片的組合 ，藉由高速馬達使彩色濾光片轉動，以將白光進行分色 ，然後將特定顏色的光束發射到DMD表面上。DMD表面由 與畫素數量對應的小反射鏡組成，這些小反射鏡根據視 頻訊號的控制而轉動，當小反射鏡轉動到其反射光束經 過投影儀的透鏡時，表示該畫素點打開，當小反射鏡轉 • 動到其反射光束偏離投影傳的透鏡時，表示該畫素點關 閉，打開和關閉的時間比表示該畫素的亮度。當紅光射 到DMD表面上時，DMD上的鏡片按照紅色視頻訊號將這些 小鏡子旋轉到開或關，使得需要顯示的反射光束經過投 影儀的透鏡投影到大螢幕上，綠色和藍色光及視頻訊號 亦是如此工作，人體視覺系統集中投影出來的紅、綠、 藍畫面便看到了一個全彩色圖像。 [0004] 請參閱圖1和圖2，其為RGB三色色輪10的俯視圖和立體圖 。色輪10包括三色濾光片100、固定部200、馬達300以 096130559 表單編號A0101 第3頁/共20頁 0993426690-0 1338122 099年11.月26日修正替換 及枯貼於固疋部·200側壁的時間標蕺（Timing

[Technical Field] The present invention relates to a parameter detection system and method, and more particularly to a color wheel parameter in a projector Detection systems and methods. [0002] • [Prior Art] At present, projectors are mainly divided into LCD type and DLP type (Digital Light Processing). Among them, DLP projector adopts DMD (Digital Micromirror Device) microlens reflection technology and adopts color wheel (Color Wheel) to complete the separation and processing of colors. [0003] In a DMD projection system, white light emitted by a light source is focused on a color wheel by a focusing lens, and the color wheel is mainly composed of a combination of color filters such as red, green, and blue, and the color filter is rotated by a high speed motor. To separate the white light, and then emit a specific color of light onto the surface of the DMD. The DMD surface consists of small mirrors corresponding to the number of pixels. These small mirrors rotate according to the control of the video signal. When the small mirror rotates until its reflected beam passes through the lens of the projector, it indicates that the pixel point is open. When the small mirror rotates to the lens whose reflected beam deviates from the projection, it indicates that the pixel point is off, and the time of opening and closing is greater than the brightness of the pixel. When red light hits the surface of the DMD, the lens on the DMD rotates the small mirrors on or off according to the red video signal, so that the reflected beam that needs to be displayed is projected onto the large screen through the lens of the projector, green and blue light and video. The signal is also working like this, and the red, green and blue images that are collectively projected by the human visual system see a full-color image. Please refer to FIG. 1 and FIG. 2, which are top and perspective views of the RGB tricolor wheel 10. The color wheel 10 includes a three-color filter 100, a fixing portion 200, and a motor 300 with a number of 096130559.

Instead, the red filter has a larger angle. The three-color filter 100 is fixed to the fixing portion 2A by holding or glue, and the motor 300 drives the three-color light-receiving sheet to rotate by driving the fixing portion 200. The time stamp 400 is used to help the projector system identify the position of the red filter 102, the green filter 1〇4 ® and the blue filter 1〇6 in the current tri-color filter 100.

It can be seen that in the color wheel 1〇 rotating at high speed, the angles of the different color filters and the recognition of the current color of the color wheel 1 by the projection instrument directly affect the color quality of the image.

Similarly, according to the second pulse The time difference between the time stamp 4〇〇 and the boundary 120, 122, 124 can be calculated from the time difference between the time pulse 502 in the number 50 and the boundary pulse 402 in the same period. [0020] The above color wheel parameter detecting system 15 is in color In the case where the wheel 10 is rotated, the first sensor 20 and the second sensor 30 emit a light beam onto the color wheel 1 并 and receive the reflected light beam 'generating the first pulse signal 40 and the second The time interval relationship of each pulse in the pulse signal 5 is determined by the angle values of the red filter 102, the green calender 104 and the blue filter 106, and the time stamp 4〇〇 and the boundaries 120, 122, 124 The angle value can be compared according to the calculated angle value to the standard angle value to determine whether the color wheel 1 符合 meets the requirements. [0021] Please refer to FIG. 5 , which is a color wheel parameter detection system according to another preferred embodiment. The architecture diagram of the instrument 2 includes a third sensor 6 〇, a mirror 7 〇 and a processor 65.

The return beam at this time includes a light beam reflected from the three-color filter 1 · and a light beam transmitted through the side walls of the mirror 70 and the fixed portion 300 after transmission, by detecting the intensity of the mixed light beam. Change, generating a pulse signal. Among them, the boundary generated by the boundary 120, 122, and 124 is defined as a boundary pulse, and the pulse generated when the time label 400 is passed is defined as a time pulse.
