BRIEF DESCRIPTION OF THE DRAWINGS
The foregoing aspects and many of the accompanying advantages of this invention will become more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
FIG. 1 is a schematic diagram of a three-lines RGB CCD arrays;
FIG. 2 is a schematic diagram of a stagger type RGB CCD arrays;
FIG. 3 is a schematic diagram of the scanner structure with two CCD arrays and two focus-image lenses which can scan the transparent media and the reflective media according to the first embodiment of the present invention;
FIG. 4A, FIG. 4B, and FIG. 4C are the schematic diagrams of the scan process for the transparent media according to the structure illustrated in FIG. 3;
FIG. 5A, FIG. 5B, and FIG. 5C are the schematic diagrams of the scan process for the reflective media according to the structure illustrated in FIG. 3;
FIG. 6A and FIG. 6A are the schematic diagrams of the scan process for a dust particle on the surface of a reflective medium according to the second embodiment of the present invention;
FIG. 7A and FIG. 7A are the schematic diagrams to illustrate the relative displacement of half pixel-distance between two CCD arrays according to the fourth embodiment of the present invention;
FIG. 8 is a schematic diagram to illustrate how the scanner memory stores the pixels' data in a stagger type for the CCD arrays illustrated in FIG. 7A and FIG. 7B; and
