Abstract: An image processing apparatus includes a dividing unit configured to divide image data into pieces of print scan image data for the plurality of print scans, a quantization unit configured to quantize the pieces of print scan image data, and a generation unit configured to generate pieces of print data for the plurality of print scans on the basis of the quantized pieces of print scan image data. In a case where a density represented by the pieces of print scan image data is a low density, the quantization unit quantizes the pieces of print scan image data so that they are mutually exclusive in the plurality of print scans.

Abstract: The present invention provides an image-processing apparatus, including: 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; a quantizing unit configured to quantize the total value; a distributing unit configured to calculate a plurality of output values corresponding to the plurality of input values by distributing the quantized value according to a ratio between each of the corrected values and the total value; and an adding unit configured to calculate respective difference values between the plurality of output values and the plurality of corrected values, and to add the calculated difference values to corrected values.

Abstract: An information processing apparatus which stores identification information (MAC address) for detection confirmation of a target network device in advance and executes detection of the target network device by comparing the stored identification information and identification information acquired from the network device on a network repeats executing a request by unicast to a part of addresses in a range of addresses to be detection target and then executing a request by broadcast or multicast until the target network device can be detected.

Abstract: An image processing apparatus configured to generate recording data used in an image forming processing for carrying out an image formation by performing a recording scan by plural times on a same image region on a recording medium, includes a division unit for dividing input image data into image data for each recording scan, a quantization unit for quantizing, based on the divided image data for each recording scan, the image data for each recording scan, and a generation unit for generating, based on the quantized image data for each recording scan, recording data for each recording scan, in which the division unit divides the input image data into the image data for each recording scan based on a division rate periodically varying in accordance with a spatial position of an image represented by the input image data.
