Image Process for Ensuring Visibility of Color Image in Black and White Printing |
| 摘要 |
An image processing apparatus includes an image processing unit configured to set a background color in color line image data to one of white and transparent and express a line-drawing color of a line-drawing object by achromatic brightness when performing black-and-white printing based on the color line image data. The image processing unit includes: an origin setting unit configured to set a brightness of the background color to an origin on a brightness axis of a hue coordinate system in a case where the background color in the color line image data is a color other than white; and a first brightness setting unit configured to set a distance from the origin to a coordinate of the line-drawing color in the hue coordinate system as a brightness of the line-drawing object for the black-and-white printing. |

1. An image processing apparatus, comprising
an image processing unit configured to set a background color in color line image data to one of white and transparent and express a line-drawing color of a line-drawing object by achromatic brightness when performing black-and-white printing based on the color line image data; the image processing unit comprising:
an origin setting unit configured to set a brightness of the background color to an origin on a brightness axis of a hue coordinate system in a case where the background color in the color line image data is a color other than white; anda first brightness setting unit configured to set a distance from the origin to a coordinate of the line-drawing color in the hue coordinate system as a brightness of the line-drawing object for the black-and-white printing. |
