Abstract
An image correction process that suppresses image deterioration in a printed image is provided. An image correction processing apparatus includes an area setting unit which sets an area comprising a plurality of pixels including an interest pixel, a first correction strength setting unit which adaptively sets a first correction strength for at least the interest pixel in the area based on the number of changes and the changing amount, a first correction unit which executes image correction for a pixel, for which the first correction strength is set, by the first correction strength, a second correction strength setting unit which adaptively sets a second correction strength for at least the interest pixel in the area based on the number of changes and the changing amount, and a second correction unit which executes image correction for a pixel, for which the first correction strength is set, by the second correction strength.
