Description of the invention (1) Field of the invention: The invention is on the background of an automatic invention: In competitive lectures and lectures, it is necessary to make one of the newspaper tools very general and the projector can be set to project the angle of the day and the day. Really, the projected image is deformed, so it is easy to change the lecture while standing in the podium, but it is distorted; because of the method of adjusting the speech, the buttons are adjusted. It is very modern in recent years. Not only must it be used as a presentation tool. Ying Ying's tool says, "When a projector is used, the projection screen is projected onto the screen. If the upward projection causes the daytime surface to be unobstructed, it is easy to block the projection film. Because the projector is inclined, this practice is conducive to the trapezoidal inconvenience of the meat image. Although in the society of the practitioners, it is not necessary to prepare materials to assist the speech. It can help the performance. It is usually placed on the table. The angle of the projector is too large, it is not as clear as the original day. In addition, the picture affects the projection of the projector to a remote control to observe the image distortion. However, the theory is that it has the same effect, and the speaker's lepton must be longer than the table. When the audience moves to the lecture screen or the keys are deformed, the speaker client will be skilled in the current loose finish, and it will take a little easier to create a wide range of speakers. High, for the trapezoidal loss of the upward tilt, and in order to avoid the effect, to manually perform a larger step to the side, the manual adjustment cannot be concentrated by hand pressing. It has been developed to automatically compensate for trapezoidal distortion. Page 4 542937 5. Description of the invention (2) The camera is "but its optics, mechanism and circuit system are complicated and expensive" and it is not easy to maintain. In view of this, the present invention is troubling to propose a projector automatic compensation correction, which causes the price to be very expensive for the above-mentioned shadow deformation problems and methods. The purpose of the invention and the device and method of the present invention are easy to project due to the projection angle, Low cost grid. The apparatus and method of the present invention are used in space. In order to reach the upper shutter plate, the groove of the shutter plate is rotated, and the light spot passing through the two shutters is output after the description: The main purpose is the advantage of tilt, the other purpose is to make the In presenting a simple design that can cause the trapezoidal loss of the image and then provide a workable system, the purpose is to provide a camera that can be described at any angle. After that, it became a little light on the first surface, and the second optical shutter issued a compensation signal to the specific and clear-headed electronic signal, so that the automatic correction of the projection compensation and correction has the automatic correction of the projection and projection received by the general public. The price of shadow distortion orthographic projection is acceptable. I shadow distortion is provided by any system. The surface is provided with at least one groove to make its center of rotation under the image on a projection screen. It is easy to understand this effect. In cooperation with the technology, the internal source of the technology's re-controller is the original attached picture volume, the first optical shutter and the first, and senses the signal input image in the narrow and long light device. When it is more successful, use a light sensor to elaborate the points and their rewards according to the ratio of the length and width of the electron.
