An image processing apparatus includes a first calculating unit (31) configured to add a pixel value and an output of a filter unit (35), a first quantizing unit (32) configured to quantize an output of the first calculating unit (31) and output a quantized value serving as ӣ modulation data, a second calculating unit (33) configured to calculate a difference between the output of the first calculating unit (31) and the quantized value, thereby obtaining the quantization error, a second quantizing unit (37) configured to quantize a portion of the quantization error and output compensating data, a third calculating unit (39) configured to add the ӣ modulation data and the compensating data, thereby generating time-integration-effect-using error diffusion data, a fourth calculating unit (34) configured to calculate a difference between the quantization error and the compensating data, the difference serving as a ӣ modulation error, and the filter unit (35) configured to perform filtering in space directions. |
