Abstract:
1. An image-processing apparatus, comprising: a corrected value calculating unit configured to calculate corrected values by adding error values diffused from a pixel neighboring a pixel currently being processed respectively to a plurality of input values corresponding to the pixel currently being processed; a total value calculating unit configured to calculate a total value of all corrected values calculated by the corrected value calculating unit; a quantizing unit configured to quantize the total value calculated by the total value calculating unit; a distributing unit configured to calculate a plurality of output values corresponding to the plurality of input values by distributing the quantized value quantized by the quantizing unit according to a ratio between each of the corrected values calculated by the corrected value calculating unit and the total value calculated by the total value calculating unit; and an adding unit configured to calculate respective difference values between the plurality of output values calculated by the distributing unit and a plurality of corrected values calculated by the corrected value calculating unit, and to add the calculated difference values to corrected values calculated by the corrected value calculating unit.
