An image processing device includes a first input-output unit connected to a first external bus, a second input-output unit connected to a second external bus, an internal bus connecting the first input-output unit and the second input-output unit and an image processing unit connected to the internal bus. The internal bus operates as a through path for passing image data without intervening with the image processing unit between the first input-output unit and the second input-output unit. After the image processing unit executes an image processing operation on image data input from one of the first input-output unit and the second input-output unit, the image processing unit outputs processed image data from another one of the first input-output unit and the second input-output unit.
