Abstract: A medical system (1) acquires a speckle image from an imaging means that images reflected light of coherent light from a subject. Furthermore, a first parameter value and a second parameter value different from each other are stored as a parameter for calculating a speckle index value that is a statistical index value for a luminance value of a speckle. Furthermore, in a case where a first mode is selected, the speckle index value is calculated on the basis of the speckle image and the first parameter value, and in a case where a second mode is selected, the speckle index value is calculated on the basis of the speckle image and the second parameter value. Then, a speckle index value image is generated on the basis of the calculated speckle index value and displayed on a display unit (74).
