    摘要: When generating outline data, the contour pixels of the binarized image data are first extracted. Based on the extracted contour pixels, the contour of the image data is approximated to a straight line. In the straight-line approximation process, the distance between adjacent contour pixels among the extracted contour pixels is calculated. It is determined based on the result of the comparison between the length of the first straight line and the length of the second straight line whether the first straight line is used as a contour of the image data. The first straight line connects the first contour pixel and the second contour pixel adjacent to the first contour pixel. The second straight line connects the second contour pixel and the third contour pixel adjacent to the second contour pixel.

    摘要: An apparatus for converting a monochrome image into a color image includes a selection portion that select, for a plurality of attributes, individual colorization methods from among a plurality of colorization methods that are defined individually such that the plurality of colorization methods correspond to at least one attribute among the plurality of attributes relating to the plurality of regions, a processing portion that colorizes the monochrome image to produce a colorized image by applying the individual colorization methods selected by the selection portion, and a determination portion that determines whether or not the colorized image satisfies a setting condition. In this apparatus, when the determination portion determines that the setting condition is not satisfied, the selection portion changes a combination of the colorization methods such that at least one among the plurality of colorization methods applied to the plurality of regions is changed. The processing portion performs re-colorization on a region having an attribute for which the selection of the colorization method is changed among colorization methods included in the combination.
