    • An image processing device of the present invention has a first element which produces partial straight lines from a straight line. One of the vertical or horizontal coordinate values of each of the partial straight lines has the same value. The image processing device has a second element which produces, based on the partial line produced by the first element, a shading range having a first and second end, wherein the first end has first color and the second end has second color, and a third element which converts the first and second colors of the shading range to third and fourth colors, which express brightness as an independent parameter. The image processing device also includes a fourth element which produces, by using the third and fourth colors converted by the third element, colors of respective pixels existing between the first end and the second end of the shading range produced by the second element, wherein the color changes smoothly from the first end to the second end.
    • 本发明的图像处理装置具有从直线产生部分直线的第一元件。 每个部分直线的垂直或水平坐标值之一具有相同的值。 图像处理装置具有第二元件,其基于由第一元件产生的部分线产生具有第一和第二端的遮蔽范围,其中第一端具有第一颜色并且第二端具有第二颜色,并且第三元件 元素,其将遮蔽范围的第一和第二颜色转换为表示作为独立参数的亮度的第三和第四颜色。 图像处理装置还包括第四元件,其通过使用由第三元素转换的第三和第四颜色产生存在于由第二元素产生的遮蔽范围的第一端和第二端之间的各个像素的颜色,其中, 颜色从第一端到第二端平滑地变化。
