Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
90 words
A method for processing a color image including a plurality of colors to replace one particular color of the color image with a second color, comprising the steps of: designating one particular color of a color image and a second color, said one particular color having a plurality of color components; inputting a color image signal; extracting said one particular color from the input color image signal; converting said one particular color to said second color; and forming a color image on the basis of the converted color image signal.
Claim 2
Independent Claim
90 words
A method for processing a color image including a plurality of colors to replace one particular color of the color image with a second color, comprising the steps of: designating one particular color of a color image and a second color, said one particular color having a plurality of color components; inputting a color image signal; extracting said one particular color from the input color image signal; converting said one particular color to said second color; and forming a color image on the basis of the converted color image signal.
Claim 3
Dependent Claim
33 words
The method of claim 1, further including the step of: selecting between outputting a color image signal indicative of the second color and outputting a signal corresponding to the input color image signal.
Claim 4
Dependent Claim
19 words
The method of claim 2, further including the step of: correcting the color of the input color image signal.
Claim 5
Independent Claim
97 words
A method for processing a color image signal to replace one particular color of the color image signal with a second color, comprising the steps of: designating one particular color of a color image and a second color; inputting a color image signal including a plurality of color component signals; extracting said one particular color from the input color image signal; converting said one particular color to said second color, said second color including a plurality of color image signal components; and forming a color image based on the color image signal converted by the converting step.
Claim 6
Independent Claim
97 words
A method for processing a color image signal to replace one particular color of the color image signal with a second color, comprising the steps of: designating one particular color of a color image and a second color; inputting a color image signal including a plurality of color component signals; extracting said one particular color from the input color image signal; converting said one particular color to said second color, said second color including a plurality of color image signal components; and forming a color image based on the color image signal converted by the converting step.
Claim 7
Dependent Claim
33 words
The method of claim 4, further including the step of: selecting between outputting a color image signal indicative of the second color and outputting a signal corresponding to the input color image signal.
Claim 8
Dependent Claim
19 words
The method of claim 5, further including the step of: correcting the color of the input color image signal.
Claim 9
Dependent Claim
140 words
A color image processing apparatus comprising: input means for providing a color image signal corresponding to an original image; memory means for storing a color image signal including a plurality of color component signals corresponding to a predetermined portion of the original image; means for determining whether the color image signal stored in said memory means corresponds to the input color image signal from said input means; means for designating a second color, to be substituted for the color image signal in said memory means; means for selectively outputting one of the input color image signal from said input means and a color image signal corresponding to the second color in accordance with an output from said determining means; and means for forming a color image of a plurality of colors in accordance with the output from said outputting means.
Claim 10
Dependent Claim
140 words
A color image processing apparatus comprising: input means for providing a color image signal corresponding to an original image; memory means for storing a color image signal including a plurality of color component signals corresponding to a predetermined portion of the original image; means for determining whether the color image signal stored in said memory means corresponds to the input color image signal from said input means; means for designating a second color, to be substituted for the color image signal in said memory means; means for selectively outputting one of the input color image signal from said input means and a color image signal corresponding to the second color in accordance with an output from said determining means; and means for forming a color image of a plurality of colors in accordance with the output from said outputting means.
Claim 11
Dependent Claim
25 words
