Abstract
In image processing, for a pixel with a density level smaller than a predetermined threshold value, the density level is corrected based on a parameter representing a degree of condensation of ink in a nozzle. For pixel with a density level equal to or larger than the predetermined threshold value, the density level is not corrected. This makes it possible to suppress an unevenness in density caused by the condensation of ink while suppressing blur at a contour of a character or a thin line.
