First Claim
Patent Images

1. A system for producing images of tissue with a medical device that delivers an illumination light to a body cavity and a color image sensor that produces images of the tissue from a number of pixels that are sensitive to different wavelengths of light, comprising:

  • an image processor coupled to receive signals produced by the color image sensor in response to illumination light reflected from the tissue having red, green, and blue color components, wherein, the image processor calculates image signals that are stored in a memory by minimizing the contribution from signals produced by the image sensor in response to red illumination light.
