Abstract
An image processing apparatus includes a quantization unit configured to use a comparison threshold value; a generating unit configured to include an error input section for inputting error data between the quantized data generated and the pre-quantization data and a memory storing a value corresponding to a difference between the comparison threshold value and an original threshold value allocated in a threshold matrix and to generate the value corresponding to the difference as an addition data that is added to a value of an input image data of the processing object pixel, without using the error data input to the error input section for adjusting the input image data of the processing object pixel; and a processing unit configured to add the value of the addition data to the value of the input image data to output input image data to which the value of the addition data is added.
