Classification: CPC H  G | IPC H

Claim 0:
1. An image processing apparatus comprising:
one or more memories; and
one or more processors,
wherein the one or more memories and the one or more processors are configured to:
acquire N-valued image data corresponding to an image including at least one object, and edge data indicating an edge area of the at least one object;
generate M-valued (N>M≥2) quantized data where each of a plurality of pixels is associated with one of a value indicating that no dot is to be recorded and a value indicating that a dot is to be recorded, based on the N-valued image data, using an image processing parameter; and
change at least one pixel, in the quantized data, among pixels that indicate the edge area of the at least one object in the edge data and have the value indicating that no dot is to be recorded in the quantized data so that the at least one pixel has the value indicating that the dot is to be recorded,
wherein a number of the at least one pixel, in the quantized data, of which the value is changed, is greater in a case where the image processing parameter is a first parameter than in a case where the image processing parameter is a second parameter.
