Information processing apparatus E.G. printing apparatus to print image based on data to be printed, determines parameter to be used based on degree of compression when error diffusion processing is performed on expanded image data

摘要

Based on information corresponding to the degree of compression of image data compressed in a lossy compression method, a parameter to be used when error diffusion processing is performed on the image data is determined.

主权项

1. An information processing apparatus comprising:
an acquisition unit configured to acquire information corresponding to a degree of compression of lossy-compressed image data to be printed; a determination unit configured to determine, based on the degree of the compression corresponding to the information acquired by the acquisition unit, a parameter to be used when error diffusion processing is performed on the image data to be printed which has been expanded, the parameter being for identifying an error which is to be distributed to a different pixel of the image, and the identified error being identified based on the parameter and an error between a pixel of target included in an image based on the image data and a predetermined threshold value; and at least one processor configured to function as the acquisition unit and the determination unit, wherein the determination unit determines a first parameter, in a case where that when the degree of compression corresponding to the information is more than a predetermined degree of compression, and determines a second parameter, in a case where the degree of compression corresponding to the information is less than or equal to the predetermined degree of compression, and wherein an error to be distributed to pixels positioned vertically and/or horizontally relative to the pixel of target in a case where the first parameter is used is smaller than that in a case where the second parameter is used.
