Summary:PROBLEM TO BE SOLVED: To generate dot data to suppress the occurrence of grain by the arrangement of dots dispersed by error diffusion processing while carrying out thinned recording without impairing a dot recording pattern when error diffusion processing is applied to thinned recording. SOLUTION: The error diffusion of binary data is performed in consideration of permitted positions shown by a division pattern of a nozzle array. That is, the binary data is permitted to be arranged only at a pixel position indicated by black in the division pattern of the nozzle array. A result of subtracting the binary data from multi-valued data is applied as multi-valued correction data, and this correction data is added to multi-valued data of the nozzle array of first pass of cyan related to second plane generation.
