Abstract:
1. A line drawing image generating device for generating line drawing data of a plurality of pixels based on original image data of another plurality of pixels, comprising: ink line pixel detecting mechanism for detecting pixels each having a brightness smaller than a predetermined value in an original image, as ink line pixels; neighboring pixel detecting mechanism for detecting a neighboring pixels of the ink line pixels, which surround the ink line pixels; outline extraction process target limitation mechanism for performing an outline extraction process for entire pixels of the original image except the ink line pixels and the neighboring pixels thereof: outline pixel detecting mechanism for detecting outline pixels, by performing the outline extraction process for the entire pixels of the original image except the ink line pixels and the neighboring pixels thereof; line drawing data storing mechanism for storing the line drawing data; and color data writing mechanism for writing color data to a storage area of the line drawing data storing mechanism, which corresponds to the ink line pixels and the outline pixels, and writing different color data to another storage area of the line drawing data storing mechanism, which corresponds to pixels other than the ink line pixels and the outline pixels.
