A method is for processing image data for recording by an image forming apparatus that discharges ink droplets from a plurality of nozzles. The method includes reading out image data corresponding to one line constituted by a series of dots aligning in a main scanning direction. The method further includes calculating a faulty discharge error, which occurs at a non-discharge position on a line at which no ink droplet is discharged from a defective one of the plurality of nozzles. The method further includes controlling distribution of the faulty discharge error to a line that is downstream relative to a line on which the non-discharge position occurs according to a limit setting that limits distribution of the faulty discharge error.

Image processing method, image processing apparatus, and non-transitory computer-readable medium

An information processing apparatus includes a resolution converting unit that converts the resolution of input image data into a low resolution by using a 'reference shift' method; a dot processing unit that deletes a dot area that occurs on an edge portion of an object in image data that is obtained by the resolution converting unit; and a format converting unit that converts image data, from which the dot is deleted by the dot processing unit, into the format of an output processing unit that prints the input image data with a low resolution.
