摘要： A data processing apparatus includes a receiving unit that receives first data that defines a shape of and a color of a surface of a three-dimensional object on each specific surface region of the three-dimensional object, and a generating unit that generates color voxel data from the first data. The generating unit assigns plural color components to plural surface voxels in accordance with color information on the color of the surface in the first data, starting with surface voxels, in a priority order of the color components from one having a lower lightness value to another having a higher lightness value, and does not assign an achromatic color component to a surface voxel if a density of the color of the surface in the first data is less than 100 percent.

摘要： An image processing apparatus includes: a multi-level unit that applies a multi-level process on binary halftone dot image data indicating a binary halftone dot image, to form multi-level image data; an acquiring unit that acquires a number of screen lines of the binary halftone dot image data; a tone correcting unit that determines a tone correction amount corresponding to the number of screen lines of the binary halftone dot image data acquired by the acquiring unit, and that applies tone correction on the multi-level image data produced by the multi-level unit, by using the determined tone correction amount; and a re-binarizing unit that binarizes the multi-level image data in which the tone is corrected by the tone correcting unit, without changing a halftone dot shape of the binary halftone dot image data, to produce re-binarized halftone dot image data.

摘要： An image processing device includes a detector that detects a target pixel as an outline pixel if a density of a predetermined region including the target pixel with each pixel of an image treated as the target pixel is equal to or above an outline determination threshold value, the outline determination threshold value being a threshold value set in response to the density of the target pixel, and being a threshold value used to determine whether the target pixel is an outline pixel corresponding to an outline of the image, and a correction unit that corrects a correction pixel, as a correction target having a density equal to or above a predetermined density from among the outline pixels detected by the detector, in response to a density of the correction pixel.

摘要： A data processing apparatus includes: a receiving unit that receives first data defining a shape and a color of a three-dimensional object; and a generating unit, wherein when two or more color components interfere with each other in one voxel as a result of performing a halftoning process for each of plural color components based on color information in the first data, the generating unit generates color voxel data by assigning any one of the two or more color components in the first data as color information of the one voxel, using a density ratio of colors corresponding to the two or more color components in the first data.
