Claim 15:
16. A medical visual aid system comprising:
an endoscope including an image capturing device and a light emitting device, the endoscope structured to generate an image data comprising a plurality of pixels representing an image, the plurality of pixels including pixels in a dark pixel area and pixels in a light pixel area, the pixels in the light pixel area being lighter than the pixels in the dark pixel area; and
an image signal processor adapted to be communicatively coupled with the endoscope, the image signal processor comprising processing instructions operable to receive the image data and apply a non-linear scaling model to the image data to form adjusted image data, to determine a body cavity type into which the endoscope will be inserted, and to select the non-linear scaling model, based on the body cavity type, from a set of non-linear scaling models, the non-linear scaling model configured to apply different intensity gains to the pixels in the light pixel area than to the pixels in the dark pixel area.
