1. A medical image processing system comprising:
a processor configured to:
acquire a medical image obtained by imaging an observation target;
calculate a feature amount of the observation target for each of pixels of an image region of the medical image or for each of divided regions obtained by dividing the image region of the medical image into a specific size;
determine a disease stage of the observation target by using a spatial distribution of the feature amount;
calculate a distribution index value which is an index value of the spatial distribution of the feature amount; and
determine the disease stage based on the distribution index value,
wherein the distribution index value is a variance of the feature amount,
the disease stage is an early stage and a progress staged,
a variation in the spatial distribution of the feature amount in the progress stage is larger than a variation in the spatial distribution of the feature amount in the early stage, and
a degree of progress of the disease stage increases as the variance of the feature amount increases.
