Summary:PROBLEM TO BE SOLVED: To provide the read image at a low cost with more fidelity to an original in the image reader of a book scanner type. SOLUTION: An optical system unit 5 is moved in a subscanning direction to read an original 8 set onto an original platen 4 and a speed detection pattern 1a. An arithmetic section 1c detects a moving speed of the optical system unit in the subscanning direction based on the speed detection pattern 1a. A memory section 2 stores data at a read line position read by the optical system unit. An image processing section 3 analyzes the read line position from the tip of the read original based on the detected moving speed of the optical system unit and corrects the read data into data at a read position specified by the specification.
