Abstract
In an image reading device including an LED array, an image sensor, and an A/D converter, an initial digitizing condition is first set while determining whether or not the initial digitizing condition to be set meets a first criteria. Then, the initial digitizing condition is adjusted so as to meet the second a second criteria. An example of the digitizing condition is a high reference voltage applied to the A/D converter which converts an analog voltage ranging from a low reference voltage to the high reference voltage to a digital value. The second criteria is provided for, for example, reducing an S/N ratio when the image reading device reads half-tone images.
