V. Description of the invention (1) [Technology of the invention The invention, especially the use of edge processing to obtain the impact point through the coordinate value on the coordinate meter, can use the restriction of photography. [Background of the invention: Pressing, sending, and low-cost displays, technically, face-to-face), plasma display challenges, and its crystal liquid crystal display (P) display tubes of various positions, and can replace the imager (TF τ TFT L Technical Field] In order to provide a device for index positioning using the photography scene> method, the imaging index device traces the image of the display area of the display screen to obtain the coordinate values of the four corners of the display area in the image, and then calculates it in different procedures. The aiming point of the camera is on the actual display screen, instead of the traditional light grabbing using the coordinate value of the impact point signal or the synchronization signal, and enabling the user to perform shooting games on the shadow indicator device on any kind of display screen without the display screen. This kind of technology has the characteristics of knowing one's own indicators (leadership indicator (technical one by one, besides, will be the commodity tube, LC CD) technology] 8 9 7, can replace film transistor PDP for a long time The TFT has already been turned on, and the products are also gradually becoming closer. The root is the current D), which has overcome the status of the LCD since the beginning of the year. . According to the ten types of industry, the most noticeable industry, especially the large daylight tube, has been adopted. However, the display (kind of flat display. Enter 9 D), the electricity is closely in place to understand, the technology of thin film thin film crystal plane for the purpose of researching the phase boundary of the display has been painted as a TV and now also a TFT display (F0's In addition to the technology in the industry before the display, it is inferred that after the liquid crystal liquid crystal is not displayed, it is also in the LCD PD which is a good computer. The thin film power (PD is leading the way. Step silkworm

588258, Invention Description (2)], ^ is considered to be a mainstream σσ-color monitor image tube (CD) market for desktop personal computer monitors. In the world: In addition, the electronic display (PDP) has been commercialized since 1985, and has completed large-scale technology development. Japan's Nagano Winter Olympics = between Japan's major manufacturers have introduced newly developed products to debut, all investment in the development and production of large plasma display (p D ρ). Of course, various projection systems other than the PDP are also available. For example, Belgian projection system developer Balker took advantage of CD technology to develop a processing system capable of processing 200 million pixels per second (pei graphic projection system 1), which can provide high-resolution images under bright lighting.

Reality 0 0 J vc also uses LCD projection technology, and has published a "Direct Drive Lighr f P 1 ifier; D-DL · A" that can display high-definition television (HDTV) day-to-day standards, or second only to S_XGA computer resolution. ". Texas Instruments (τ 工) also published a projection technology called DMD. This product can provide clear and vivid day quality, but it is understood that the life of the projection lamp is only 250 to 500 hours, and the noise of the cooling fan is also slightly higher, which is the lack of improvement. In addition, 3D projection systems using lasers or holograms (0.1 g r a m) have also made considerable progress. It can be seen that the development of display technology can be described as a cutting edge display (Fie 1 d Emission, =: p 1 ay; FED) and other thin-film transistor liquid crystal display (TFT LCD), electro-poly display (PDP) and other cutting-edge monitor
