Abstract
An object of the present disclosure is to reduce density unevenness and streaks of an image that is printed in a case where it is not possible to implement sufficient correction only by the correction for a defective nozzle. One embodiment of the present invention is an image processing apparatus that performs processing for an input image for an image forming apparatus performing printing on a printing medium by using a print head in which a plurality of printing elements is arrayed, the image processing apparatus including: a storage unit configured to store density characteristic information indicating an output density for each tone for each of the printing elements; a target value acquisition unit configured to acquire a target characteristic indicating a target value for each tone; and a first correction unit configured to correct the input image based on the density characteristic information and the target value.
