An image processing device comprises an image reader section, an A/D converter section, a speed detection roller, an encoder, and an image information precision control section. The image reader section detects the intensity of one or more colors on a subject on which the image reader section moves, and outputs an electrical signal corresponding to the intensity. The A/D converter section quantizes the electric signal to a digital signal. The movement speed of the image reader section which is moving on the subject is detected by the speed detection roller and the encoder. The image information precision control section controls quantization precision of the digital signal according to the movement speed detected by the speed detection roller and the encoder. According to the image processing device, the amount of data which is outputted to an external device such as a personal computer via an interface is automatically limited adequately according to the movement speed, thereby precise and relatively high quality images can be obtained constantly regardless of the movement speed, without causing image contraction, disappearance of pixel image information, or wrong colors.
