Abstract
A method of controlling a color image forming apparatus capable of preventing an image from being distorted at a boundary of a color image region due to mis-registration to improve printing quality. The method includes determining whether original image data is in a color image region, detecting boundary region information on a plurality of color channels when the original image data is in the color image region, selecting a channel to be extended using the detected boundary region information, and extending the selected channel.

A method of controlling a color image forming apparatus that prints a color image using a plurality of color channels, the method comprising:
- determining whether original image data is in a color image region;
- detecting boundary region information on the plurality of color channels when it is determined that the original image data is in the color image region;
- and
- selecting a color channel to be extended using the detected boundary region information and extending the selected channel.
A method of controlling a color image forming apparatus that prints a color image using a plurality of color channels, the method comprising:
- determining whether original image data is in a color image region based on whether patterns of the color channels coincide with each other and whether a reference color channel is flat;
- extracting edge information and directional information on the color channels and detecting boundary region information on the color channels based on the extracted edge information and directional information when it is determined that the original image data is in the color image region;
- and
- selecting a channel to be extended using the detected boundary region information and extending the selected channel.
A method of controlling a color image forming apparatus that prints a color image using a plurality of color channels, the method comprising:
- determining boundary information of the plurality of color channels to determine whether original image data are is in a color image region;
- and
- extending one color channel using the detected boundary according to whether the color channels are adjacent.
