Abstract
Abstract An image processing apparatus includes a brightness extracting element for extracting information relating to brightness from color image data; an image attribute judging element for judging a light-color image portion in a color image; and a brightness change section which changes brightness of the light-color image portion. The image attribute judging element includes a separating device for separating foreground data and background data from the color image data; and a comparing section which, when a difference in brightness between the foreground and the background separated by said separating device is smaller than a predetermined value, judges the foreground data as data of a light-color image portion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
104 words
An image processing apparatus comprising: brightness extracting means for extracting information relating to brightness from color image data; image attribute judging means for judging a light-color image portion in a color image; and a brightness change section which changes brightness of the light-color image portion, wherein said image attribute judging means comprises: separating means for separating foreground data and background data from the color image data; and a comparing section which, when a difference in brightness between the foreground and the background separated by said separating means is smaller than a predetermined value, judges the foreground data as data of a light-color image portion.
Claim 2
Dependent Claim
104 words
An image processing apparatus comprising: brightness extracting means for extracting information relating to brightness from color image data; image attribute judging means for judging a light-color image portion in a color image; and a brightness change section which changes brightness of the light-color image portion, wherein said image attribute judging means comprises: separating means for separating foreground data and background data from the color image data; and a comparing section which, when a difference in brightness between the foreground and the background separated by said separating means is smaller than a predetermined value, judges the foreground data as data of a light-color image portion.
Claim 3
Dependent Claim
25 words
The image processing apparatus according to claim 1 , wherein said brightness extracting means extracts brightness information from the color image data after color compression.
Claim 4
Dependent Claim
36 words
The image processing apparatus according to claim 2 , wherein said brightness change section changes the brightness of the whole image portion which is judged as a light-color image portion by said image attribute judging means.
Claim 5
Dependent Claim
36 words
The image processing apparatus according to claim 1 , wherein said brightness change section changes the brightness of the whole image portion which is judged as a light-color image portion by said image attribute judging means.
Claim 6
Dependent Claim
36 words
The image processing apparatus according to claim 2 , wherein said brightness change section changes the brightness of the whole image portion which is judged as a light-color image portion by said image attribute judging means.
Claim 7
Dependent Claim
16 words
The image processing apparatus according to claim 5 , wherein the foreground data are character data.
Claim 8
Dependent Claim
16 words
The image processing apparatus according to claim 1 , wherein the foreground data are character data.
Claim 9
Dependent Claim
61 words
An image processing apparatus comprising: receiving means for receiving color image data; first detecting means for detecting brightness of a character portion of the color image data; second detecting means for detecting brightness of a background portion of the color image data; and changing means for changing the brightness of a character portion of the color image data based on result.
Claim 10
Dependent Claim
61 words
An image processing apparatus comprising: receiving means for receiving color image data; first detecting means for detecting brightness of a character portion of the color image data; second detecting means for detecting brightness of a background portion of the color image data; and changing means for changing the brightness of a character portion of the color image data based on result.
Claim 11
Dependent Claim
47 words
The image processing apparatus according to claim 8 , wherein the changing means changes the brightness of the character portion of the color image data if a difference between the brightness of the character portion and the brightness of the background portion is within a predetermined value.
