Abstract:
An image processing apparatus including an input unit which inputs a pixel value of a multi-level notice pixel, a first add unit which acids an error value to the input value, a second add unit which adds a green noise value to the input value, a threshold processing unit which outputs an binarized output values a green noise calculation unit which calculates the green noise value, a subtract unit which calculates an error value due to binarization, an error diffusion unit which diffuses the calculated error value to an untreated pixel which is not yet binarized and a correction processing unit which adds a positive first offset to the error value to perform a correction and outputs the corrected error value to the first add unit.
