In recent years, due to the rapid advancement of optoelectronic semiconductor technology, the technology of optical scanners has advanced by leaps and bounds and has become more and more common, and has now become a product of electrical: peripheral equipment. 细 ， 今 ## = Technology_, such as touch, damage or fingerprint repair of the scanned object, 'Infrared technology has been used to detect defects, and has been used publicly. ~ However, for the use of infrared technology in conventional technology as Image repair technology often uses visible light (meaning white light) and infrared light to be emitted separately. # Take different filters and light sources to detect the scanned object. For all the use of infrared technology as The __ image measurement and repair is the use of infrared wavelengths different from visible light to detect image defects, defects, to further repair the stored image data. For example, the Republic of China Patent No. 7-2009 On the 27th, the invention of the "Glue #scanning dust reduction and Wei correction technology" invention, in which the Jiecun scanner uses infrared light to detect whether the image is damaged or lacking, or there is an extraneous matter attached.

Mesh like. After detecting the lack of the film, it is processed by the computer's image and removed according to the electromagnetic spectrum generated by the different lack. However, the above two conventional techniques for detecting and repairing missing images are mainly based on the fact that in this technique, visible light and infrared light are emitted separately to obtain different light sources. Visible light sources (that is, white light sources) need to be turned off or on frequently. In this case, the scanner must increase the warm-up time, causing inconvenience to the user, and the scanner cannot maintain the normally open use state. ^ In addition, Figure 1 is a schematic diagram of the scanner light source projection using two light sources in conventional technology, mainly one is the white light source 10 and the other is the infrared light source 20, both of which are dependent on the emission and the The film 40 to be scanned is detected, and then the light is irradiated to the charge coupling device (CCD) 30 to further complete the scanning image reading. Among them, FIG. 1A shows the two lights $ 10 and 20. When the white light source 10 is irradiated (that is, the state is turned on), the infrared light source 20 is turned off. On the other hand, as shown in FIG. B, when the infrared light source 20 is irradiated, the white light source 10 is in an OFF state. Therefore, in the conventional technology, the technology using the white light source 10 and the infrared light source 20 often depends on the light gauge 10 _ during actual scanning, so that the paper size of the original disc can be applied to the country of China (2 琊 琊 mm) --- Dragging clothes m * (Please read the precautions on the back before filling this page)
