    • Image data is divided into blocks and a histogram of a color appearing in a target block is formed. A target color region is decided as significant, if the area of that region is larger than a threshold, or if that area is smaller than the threshold and if that region is located at a boundary of the target block and attribute information for the pixel at the boundary in that region indicates a preset attribute. If that region is not decided as significant, to integrate that region to a region of another color which contacts that region, the color of the pixel in that region is substituted by the other color. If that region is decided as significant and if the chrominance difference between that region and the region decided as significant in another block which contacts the target block is smaller than another threshold, these regions are integrated.
    • 图像数据被分成块,并且形成出现在目标块中的颜色的直方图。 如果该区域的面积大于阈值,或者如果该区域小于阈值,并且如果该区域位于目标块的边界并且该像素的边界处于 该区域中的边界表示预设属性。 如果该区域未被确定为重要的区域,则为了将该区域整合到与该区域接触的另一种颜色的区域,该区域中的像素的颜色被另一种颜色替代。 如果该区域被确定为显着,并且如果该区域和接触目标块的另一块中被确定为有效区域的色度差小于另一个阈值,则这些区域被积分。
