Abstract
Abstract A color image processing system comprises a device for taking an image of an object, a first converting device for converting the image information obtained by the imaging device into red, green, and blue images, a second converting device for converting the red, green, and blue images into images representing intensity, saturation, and hue respectively, and a third converting device for converting the images representing the intensity, saturation, and hue into red, green, and blue images.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
82 words
An endoscopic system comprising: imaging means disposed in a scope portion of an endoscope, for taking an image of an object; first formation means for forming first color images of red, green, and blue, the image obtained by said imaging means; second formation means for forming at least one second color image of hue, intensity, and saturation based on the first color images formed by said first formation means; and display means for displaying at least one of the first color images.
Claim 2
Dependent Claim
82 words
An endoscopic system comprising: imaging means disposed in a scope portion of an endoscope, for taking an image of an object; first formation means for forming first color images of red, green, and blue, the image obtained by said imaging means; second formation means for forming at least one second color image of hue, intensity, and saturation based on the first color images formed by said first formation means; and display means for displaying at least one of the first color images.
Claim 3
Dependent Claim
31 words
An endoscopic system as claimed in claim 1, wherein said display means dividedly displays said first color image and at least the one second color image on the same display surface.
Claim 4
Dependent Claim
148 words
An endoscopic system, comprising: imaging means arranged in a scope portion of an endoscope, for taking an image of an object; first formation means for forming first color images of red, green and blue, based on the image obtained by the imaging means; second formation means for forming at least one second color image of hue, saturation and intensity based on the first color images formed by the first formation means; display means for displaying at least the one second color image; setting means for setting upper and lower threshold values for at least one of the hue, saturation and intensity; and image processing means for differently processing pixels inside the threshold values set by the setting means and pixels outside the threshold values in at least one of the hue, saturation and intensity, the image processed by the image processing means being displayed by the displayed means.
Claim 5
Dependent Claim
148 words
An endoscopic system, comprising: imaging means arranged in a scope portion of an endoscope, for taking an image of an object; first formation means for forming first color images of red, green and blue, based on the image obtained by the imaging means; second formation means for forming at least one second color image of hue, saturation and intensity based on the first color images formed by the first formation means; display means for displaying at least the one second color image; setting means for setting upper and lower threshold values for at least one of the hue, saturation and intensity; and image processing means for differently processing pixels inside the threshold values set by the setting means and pixels outside the threshold values in at least one of the hue, saturation and intensity, the image processed by the image processing means being displayed by the displayed means.
Claim 6
Dependent Claim
28 words
An endoscopic system as claimed in claim 4, wherein said image processing means processes the saturation so that the pixels outside said threshold values may be achromatic colors.
Claim 7
Dependent Claim
30 words
An endoscopic system as claimed in claim 3, wherein said image processing means processes the hue and saturation so that the pixels inside said threshold values may be pseudo colors.
