Abstract:
1. An image processing device comprising: a first element which produces partial straight lines in a background, each of which has a horizontal axis, wherein each of said horizontal axes are parallel with each other; a second element which separates a color brightness data, expressed in a brightness-separable YUV color space where color can be expressed by being separated into brightness and chromaticity, of said background and each of said partial straight lines; and a third element which produces a shading range having a starting point and a ending point, wherein said shading range is adjacent to one of said partial straight lines, and makes the brightness of said shading range change smoothly in said brightness-separable YUV color space, from said starting point to said ending point by placing the brightness data of said background at said starting point and the brightness data of said straight line at said ending point.
