摘要：
An image processing apparatus comprises
means (302) for binarizing multi-value image data using a threshold matrix,
characterised in that
said binarizing means (302) outputs binary image signals to an image forming appartus for forming an image at a selected one of a plurality of recording resolutions;
said binarizing means (302) comprises means (301) for selecting one of a plurality of threshold matrixes different from each other in accordance with the recording resolution at which image formation is to be performed by said image forming apparatus; and
said binarizing means (302) binarizes the multi-value image data using the threshold matrix selected by said selecting means (301).
