Abstract
An image reading apparatus disclosed in this invention has first and second line sensors. The output from the first line sensor is compressed by a first compression circuit, and the output from the second line sensor is compressed by a second compression circuit. Furthermore, control is made to output image data for one page compressed by the first compression circuit, and thereafter, to output image data for one page compressed by the second compression circuit. The first compression circuit can operate at a higher speed than the second compression circuit.
