Abstract
An image reading apparatus includes a line sensor for reading an image of a document sheet, an A/D converter for converting image data from the line sensor to multi-level image data, a binarization comparator for converting the multi-level image data from the A/D converter to bi-level image data and an image processing IC for selectively outputting the multi-level image data from the A/D converter and the bi-level image data from the binarization comparator. The number of read pixels in the multi-level image data output mode is set to be smaller than the number of read pixels in the bi-level image data output mode.
