ABSTRACT:
The image reading apparatus is able to execute two image density controls. In one image density control, the image density of the document is detected and adjusted based on the detection, and in the other image density control, the document height is detected and the image density of the document is adjusted based on the detected height. Either of the two image density controls is selected based on the type or the shape of the document for execution of the density control.
