ABSTRACT:
An image processor determines a binarization threshold value used for binarizing a multi-valued image, and performs binarization processing on the multi-valued image. The multi-valued image is input line-sequentially, the binarization threshold values are determined sequentially in units of predetermined size blocks each including a plurality of pixels, and the multi-valued image data is binarized line-sequentially. The inputting of data, determining the threshold value, and binarization of the multi-value image data is performed by pipeline processing.
