An image processing device may create corrected image data by correcting object image data utilizing base image data. The image processing device may determine a first representative value which represents first pixels having a higher brightness value among entire pixels of the object image data, determine a second representative value which represents second pixels having a higher brightness value among entire pixels of the base image data, and create the corrected image data by correcting a value of each pixel of the object image data such that the first representative value approaches the second representative value.
