Abstract:
1. An image reading system which can read a film original and performs at least two scanning operations including pre-scanning and actual scanning, comprising: a film type selecting unit; an image data converter adapted to convert pre-scanned image data; and an image display unit; wherein a film type can be selected by said film type selecting unit after obtaining at least pre-scanned image data, wherein if the film type is changed by said film type selecting unit after obtaining pre-scanned image data, the pre-scanned image data is converted by said image data converter in accordance with the changed film type, and the converted result of the pre-scanned image data can be confirmed by displaying the resulting image by said image display unit before the actual scanning is performed, and wherein said image changing unit comprises a calculation unit adapted to calculate a difference between a color conversion table used to acquire pre-scanned image data and a color conversion table corresponding to a film type newly selected by said film type selecting unit after acquiring pre-scanned image data, and means for adding the calculated difference to the pre-scanned image data.
