<p>In a color image reading apparatus, an image of a document, is imaged on an image sensor (8) constituted by a photosensor array, through first and second color separation filters (6, 7) having filter elements (2l, 22) of different spectral characteristics. The color separation filters (6, 7) are respectively moved by first and second drive means (l4, l5), so that at least three color image signals are selectively generated from the image sensor (8) in accordance with the combinations of positional states of the filters (6, 7).</p> |
