Abstract
An image processing apparatus includes an input unit for inputting a color image signal, an extraction unit for extracting an outline portion from the color image signal, and an output unit for outputting the outline portion extracted by the extraction unit in multi-colors indicated by the color image signal.
Claims38
An image processing apparatus comprising:
- a) input means for inputting a color image signal;
- b) extraction means for extracting an outline portion from the color image signal;
- and
- c) output means for removing the color image signal in an area other than the outline portion and outputting, the color image signal representing the extracted outline portion in multi-colors based on the color image signal input by said input means.

1 more element
An image processing apparatus comprising:
- a) outline extraction means for extracting an outline of an input image;
- b) color designation means comprising a display for manually designating a converting-color to be applied to the extracted outline in accordance with said display;
- c) color conversion means for converting a color of the outline according to the converting-color designated by said color designation means;
- and
- removal means for removing the input image in an area other than the outline.
2 more elements
An image processing apparatus comprising:
- a) extraction means for extracting an outline portion of an original image;
- b) removal means for removing the original image in an area other than the outline portion;
- and
- c) selection means for selecting a first mode or a second mode, wherein the outline portion is colored in colors of the original image and then output in said first mode, and wherein the outline portion is colored in colors, the number of which is less than the number of the colors of the original image, and then output in said second mode.
