Abstract:
1. An image processing apparatus for forming an image by performing a plurality of times of recording on a same region of a recording medium by using a recording head including a plurality of recording elements for each of a first color material and a second color material different from the first color material, the image processing apparatus comprising: an input unit configured to input image data of each of the first color material and the second color material; and a generation unit configured to generate recording data corresponding to each scan of the first color material and the second color material based on the image data of the first color material and the second color material, the recording data being used for assigning a recording amount represented by a pixel value of a pixel constituting the image data to each of the recording elements for the first color material and the second color material; wherein the generation unit generates, in a case where the plurality of recording elements for recording the first color material includes at least a defective recording element, recording data corresponding to each scan of the first color material so that a recording amount assigned to the defective recording element is complemented with a recording element corresponding to the first color material different from the defective recording element, and assignment to a recording element of each pixel constituting the image data corresponding to the second color material is changed so that impact order between the first color material and the second color material is not changed, and the generation unit generates recording data corresponding to each scan of the second color material according to a recording position of the recording element to complement the defective recording element.
