Abstract
An image processing device may create corrected image data by correcting target image data. The image processing device may determine a representative value which represents specific pixels in the object image data, determine a target value based on the representative value and a degree of correction designated by a user, and correct a value of each particular pixel included in the object image data such that the value of the each particular pixel approaches the target value. The each particular pixel may be included in a surrounding area of the representative value.
