An image processing apparatus adjusts first and second component images. The adjusted first component image has a pixel count in a prescribed direction determinative of a first resolution. The adjusted second component image has a pixel count in the prescribed direction determinative of a second resolution lower than the first resolution. Each adjusted component image is generated by: selecting a target pixel; acquiring gradation values of correspondence pixels in the pre-adjusted component image; and determining a gradation value of the target pixel based on gradation values of the correspondence pixels. The correspondence pixels are overlapped by the target pixel when the pre-adjusted component images are shifted in the prescribed direction relative to the adjusted component images and superimposed in the adjusted component image.
