Claim 0:
1. A device for the qualitative evaluation of a liver, comprising:
a camera for capturing light in the visible spectrum reflected from a visually exposed liver, said camera is configured to obtain an image of said liver by color photography or color videorecording, the liver being visually exposed in a donor's body or already collected or placed in a hypothermic, normothermic and/or subnormothermic graft perfusion machine at the time of image capture;
a sterile cover configured to contain the camera as well as a light source for illuminating the donor's organ, while maintaining the sterility of the surgical field, said sterile cover including a transparent image capture window to be positioned in front of a lens of the camera:
an image processor configured for applying a trimming mask to the captured image, said trimming mask comprising a trimming portion corresponding to the brightest image portions, which correspond to reflections of the light emitted by the light source on the liver, to obtain a trimmed image,
said image processor is further configured to extract at least a portion of the liver's image from the trimmed image and to determine at least the color of the liver; and,
means for estimating, from the extracted image, the steatosis rate of the liver based at least on the color of the liver.
