Abstract:
A method of scanning an original image containing image information of different types, the method comprising scanning the original image by causing relative scanning movement between a CCD sensor and the original image while the original image is illuminated, the CCD sensor including on the same substrate at least one first linear array of photosites, and a second linear array of photosites, the pitch between adjacent photosites of the second linear array being different from the pitch between adjacent photosites of the or each first array; and monitoring output signals from the at least one first linear array when the at least one first linear array is scanned over a first type of image information and monitoring output signals from the second linear array when the second linear array is scanned over a second type of image information; the method further comprising, prior to said scanning, performing a prescan of the original image to define the locations of the different types of image information.
