Color image processing device having ability to process and record an outside or inside region enclosed with a color marker

An image recording apparatus for detecting a region marked with a color on a document, the color being a different color from colors of an original image on said document, said apparatus comprising color discriminating means for separating an image including said region and said original image into a plural of color components, obtaining a color image signal having plural component signals for each pixel of said region and said original image, by reading said separated color components for each said pixel, and discriminating a color of each of said pixel as one of predetermined plural colors based on said color image signal;

• converting means for converting said color image signal into an image signal having a color code indicating said discriminated color and density data indicating density,
• region detecting means for detecting said region by detecting said different color based on said color code,
• image processing means for performing different image processings between the inside and the outside of said region detected on the basis of the output of said region detecting means;
• and
• recording means for recording the output signal of said image processing means.

An image processing apparatus comprising

• color discriminating means for separating an image on a document into plural of color components, obtaining a color image signal having plural component signals for each pixel of said image by reading said separated color components for each said pixel, discriminating a color of each said pixel as one of predetermined plural colors based on said color image signal, and converting said color image signal into an image signal having a color code indicating said discriminated color and density data indicating density;
• means for selecting a color code corresponding to a color to be recorded;
• means for obtaining a density width from said density data of said image signal having said color code;
• means for calculating a threshold value based on said density width;
• means for coding said density data of said image signal into at least one coded signal based on said threshold value;
• and
• means for performing color recording for said coded signal with the color to be recorded.

An image processing apparatus comprising

• separating means for separating into plural color components optical information obtained by scanning a document;
• converting means for converting said plural color components for each pixel into plural electric signals by a photoelectric converting element;
• and
• color discriminating means for discriminating a color of each said pixel as one of predetermined plural colors based on said plural electric signals and outputting an image signal having a color code indicating said discriminated color and density data for each said pixel, said color discriminating means being replaceable with another color discriminating means.
