1. An image processing apparatus or processing color charts, said image processing apparatus comprising:
- a maintenance part configured to maintain color conversion information mapping each of a plurality of colors to a corresponding line pattern;
a determination part configured to receive color image data for an image, determine a two-dimensional area of the image having a first color that is homogeneous in said two-dimensional area, and determine, based on the color conversion information maintained by the maintenance part, a first line pattern corresponding to the first color; and
a processing part configured to modify the image by reproducing the two-dimensional area with the first line pattern in place of the first color, to generate a converted image,wherein the determination part determines that adjacent two-dimensional areas of the image include different shades of a particular color, andthe processing part adjusts a line pattern corresponding to one of said adjacent two-dimensional areas, by increasing or decreasing the width of the lines in the line pattern.

9. An image processing apparatus for processing color charts, said image processing apparatus comprising;
-
a maintenance part configured to maintain color conversion information mapping each of a plurality of colors to a corresponding line pattern; a determination part configured to receive color image data for an image, determine a two-dimensional area of the image having a first color that is homogeneous in said two-dimensional area, and determine, based on the color conversion information maintained by the maintenance part, a first line pattern corresponding to the first color; and a processing part configured to modify the image by reproducing the two-dimensional area with the first line pattern in place of the first color, to generate a converted image, wherein the determination part determines that line patterns in adjacent two-dimensional areas of the converted image have similar properties, and the processing part adjusts a line pattern amongst said line patterns in the adjacent two-dimensional areas of the converted image, by increasing or decreasing the width of the lines in the line pattern.

10. An image processing apparatus for processing color charts, said image processing apparatus comprising;
-
a maintenance part configured to maintain color conversion information mapping each of a plurality of line patterns to a corresponding color; a determination part configured to receive image data for an age, determine a two-dimensional area of the image having a line pattern that is homogeneous in said two-dimensional area, and determine, based on the color conversion information maintained by the maintenance part, a first color corresponding to the line pattern; and a processing part configured to modify the image by reproducing the two-dimensional area with the first color in place of the line pattern, to generate a converted image, wherein the determination part determines that line patterns in adjacent two-dimensional areas of the converted image have similar properties, and the processing part adjusts a line pattern amongst said line patterns in the adjacent two-dimensional areas of the converted image by increasing or decreasing distance between lines in the line pattern. - View Dependent Claims (11)
