Abstract
An image processing apparatus generates and outputs a binarized output pixel value corresponding to an input pixel value; and includes a filter processing unit, a quantizer, and a buffer. The quantizer is configured to quantize a pixel value after a filter process performed by the filter processing unit and thereby generate the output pixel value. The buffer is configured to store for each pixel a difference between (a) a sum of the pixel value after the filter process and the input pixel value and (b) the output pixel value. Further, the filter processing unit performs a bandpass filter process on the basis of the difference stored by the buffer.
