Abstract:
1. An image processing apparatus that, for printing an image on a predetermined area of a printing medium by performing a plurality of relative scans between a printing unit for ejecting inks of a plurality of colors and the printing medium, processes multi-valued image data that corresponds to the image to be printed on the predetermined area, said apparatus comprising: a generating unit configured to generate respective multi-valued data that correspond to each of the plurality of relative scans and multi-valued data that corresponds commonly to at least two relative scans among the plurality of relative scans, by dividing the multi-valued image data according to division ratios according to an ink color that corresponds to the multi-valued image data; a quantization unit configured to perform quantization processing for each of the multi-valued data generated by said generating unit to generate respective quantized data that correspond to each of the plurality of relative scans and quantized data that corresponds commonly to the at least two relative scans among the plurality of relative scans; and a combination unit configured to combine the quantized data generated by said quantization unit for each corresponding relative scan to generate combined quantized data that corresponds to each of the plurality of relative scans.
