Medical system, information processing device, and information processing method

An information processing device, comprising:

• an acquiring means that acquires a speckle image from an imaging means that captures an image of reflected light of coherent light with which a subject is irradiated;
• a calculating means that performs, for each pixel of the speckle image, on the basis of luminance values of that pixel and surrounding pixels, statistical processing and calculation of a predetermined index value;
• a determining means that determines, for the each pixel, whether or not a mean of the luminance values used in the calculation of the index value is in a predetermined range;
• a generating means that generates a predetermined image on the basis of the index values;
• and
• a display control means that identifiably displays, in displaying the predetermined image on a display means, a portion of pixels each having a mean of the luminance values, the mean being outside the predetermined range.
