Medical image processing system, endoscope system, diagnostic support apparatus, and medical service support apparatus

A medical image processing system, comprising:

• a light source that emits a plurality of illumination light beams having different wavelength bands and different visibilities for red blood cells;
• and
• a processor configured to:
• acquire a plurality of medical images corresponding to respective illumination light beams by imaging an observation target illuminated with the respective illumination light beams;
• acquire a red blood cell index value, which is obtained by indexing the visibility of red blood cells, from each of the medical images;
• and
• determine a state of the observation target from the red blood cell index value with reference to a correlation between the state of the observation target and the red blood cell index value,
• wherein the plurality of illumination light beams include first illumination light having a center wavelength of 410 nm and second illumination light having a center wavelength of 450 nm,
• the processor acquires a first red blood cell index value from a medical image corresponding to the first illumination light, and acquires a second red blood cell index value from a medical image corresponding to the second illumination light, and
• the processor determines that there is no precipitation amount of the red blood cells in a case where both the first red blood cell index value and the second red blood cell index value indicate that the red blood cells are not visually recognizable, determines that the precipitation amount of the red blood cells is equal to or less than a specific value in a case where the first red blood cell index value indicates that the red blood cells are visually recognizable and the second red blood cell index value indicates that the red blood cells are not visually recognizable, and determines that the precipitation amount of the red blood cells exceeds the specific value in a case where both the first red blood cell index value and the second red blood cell index value indicate that the red blood cells are visually recognizable.
