Abstract: A double-light sources optical scanning device and method of using the same is disclosed. The double-light sources optical scanning device comprises: a light-source backlight module, an optical lens, and an area optical sensing device. The light-source backlight module comprising a white light source and an infrared light source, irradiating at least an object for scanning to generate an image. The optical lens projects the image to the area optical sensing device and divides the image generated by the white light source and the infrared light source. Turning on the white light source or the infrared light source through a switching control circuit, wherein determining where the contaminative positions are placed on the object by irradiating with infrared, and cleaning and repairing contaminations and damages shown in the image generated by the white light source.

Abstract: A double-lens optical scanning device and method of using the same. Wherein, a housing of said optical scanning device is provided with a photograph cartridge insertion slot and a negative cartridge insertion slot, that can be inserted photograph-, negative-, or slide-to-be-scanned. Said housing comprises a light source, two optical lenses, and at least an image sensor. Said two optical lenses are provided with different light paths, such that said image sensor is utilized to determine a category of an object-to-be-scanned, in selecting said optical lens to be used and a direction of said light source. A switching circuit is utilized to switch said optical lens to be used, fetch an image of said object-to-be-scanned, and then focus it onto said image sensor to form said image, and convert it into digital data for output.

Abstract: The invention provides a scanner with integrated storage means, such as a compact disc (CD) writer or digital video disc (DVD) writer. After an image is scanned, it can easily be transferred and saved to the removable storage media such as a compact disc. The images are formatted into a slideshow in VCD format for convenient viewing. The scanned data can easily be viewed on a television connected to the device or since the storage media is removable and portable, moved and viewed in another location. A memory card reader allows images stored on digital camera memory cards to be transferred to CD.
