Abstract
Abstract An image processing apparatus for processing a digital color signal, given from outside the image processing apparatus, into a digital color recording signal, comprising; a color code generator for generating a color code signal representing a color of a digital pixel image signal, and a color reproduction unit for generating a color recording signal by processing another digital pixel image signal, in which these two digital pixel image signals are processed separately.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
73 words
An image processing apparatus for processing a digital color signal, given from outside said image processing apparatus, into a digital color recording signal, comprising; a color code generating means for generating a color code signal representing a color of a first digital signal, and a color reproduction means for generating a color recording signal by processing a second digital signal, wherein said first digital signal and said second digital signal are processed separately.
Claim 2
Dependent Claim
73 words
An image processing apparatus for processing a digital color signal, given from outside said image processing apparatus, into a digital color recording signal, comprising; a color code generating means for generating a color code signal representing a color of a first digital signal, and a color reproduction means for generating a color recording signal by processing a second digital signal, wherein said first digital signal and said second digital signal are processed separately.
Claim 3
Dependent Claim
49 words
The apparatus claimed in claim 1, wherein said color code generating means generates said color code signal which identifies the color of said first digital signal as one of white, achromatic, and chromatic colors, and said color reproduction means forms a color image according to said color code signal.
Claim 4
Dependent Claim
65 words
The apparatus claimed in claim 1, further comprising a color compensation means for generating said second digital signal by adjusting a color balance of said digital color signal, and a means for forming a color image with a plurality of recording toners, wherein said color reproduction means processes said second digital signal into said digital color recording signal for each color of said recording toners.
Claim 5
Dependent Claim
45 words
The apparatus claimed in claim 1, further comprising a document scanning means for scanning a document so that said digital color signal for said document is obtained, and a means for processing said color code signal so that a background color of document is obtained.
Claim 6
Dependent Claim
56 words
The apparatus claimed in claim 2, further comprising a mono-chrome reproduction means for generating a mono-chrome recording signal by processing said digital color signal, and a selection means for selecting one of said color reproduction means and said mono-chrome reproduction means according to said color code signal so that said digital color signal is processed thereby.
Claim 7
Dependent Claim
84 words
An image processing apparatus for reproducing a color document, comprising; a means for scanning said document so that an image information corresponding to each scanning pixel is obtained, wherein said image information represents as one of white, achromatic, and chromatic colors, and a means for identifying said document as one of a monochromatic image document and a color image document according to said image information, wherein said image processing apparatus processes said reproduction of a color document according to the identification of said document.
Claim 8
Dependent Claim
84 words
An image processing apparatus for reproducing a color document, comprising; a means for scanning said document so that an image information corresponding to each scanning pixel is obtained, wherein said image information represents as one of white, achromatic, and chromatic colors, and a means for identifying said document as one of a monochromatic image document and a color image document according to said image information, wherein said image processing apparatus processes said reproduction of a color document according to the identification of said document.
Claim 9
Dependent Claim
26 words
The apparatus claimed in claim 6, wherein said identifying means operate in accordance with a count value of a color code obtained from said image information.
Claim 10
Dependent Claim
81 words
An image processing apparatus for processing a digital color signal, given from outside said image processing apparatus, into a digital color recording signal for recording with a plurality of recording toners, comprising; a color compensation means for adjusting a color balance of said digital color signal, a means for forming a color image with said plurality of recording toners, a color reproduction means proceses said digital color signal into said digital color recording signal for each color of said recording toners.
Claim 11
Dependent Claim
81 words
An image processing apparatus for processing a digital color signal, given from outside said image processing apparatus, into a digital color recording signal for recording with a plurality of recording toners, comprising; a color compensation means for adjusting a color balance of said digital color signal, a means for forming a color image with said plurality of recording toners, a color reproduction means proceses said digital color signal into said digital color recording signal for each color of said recording toners.
Claim 12
Dependent Claim
57 words
The apparatus claimed in claim 8, further comprising a color code generating means for generating a color code signal representing a color of a first digital signal, and a color reproduction means for generating a color recording signal by processing a second digital signal, wherein said first digital signal and said second digital signal are processed separately.
Claim 13
Dependent Claim
65 words
The apparatus claimed in claim 2, further comprises a color compensation means for generating said second digital signal by adjusting a color balance of said digital color signal, and a means for forming said color image with a plurality of recording toners, wherein said color reproduction means processes said second digital signal into said digital color recording signal for each color of said recording toners.
