1. A medical image processing device that inputs an image acquired by a medical imaging apparatus and outputs an image in which noise is reduced, the medical image processing device comprising:
a plurality of processors for noise reduction;
an analysis unit configured to analyze a pattern of a signal and noise of the input image and classify the input image; and
a processor selection unit configured to select one or a plurality of processors from the plurality of processors based on a classification result of the analysis unit and activate the selected processor,
wherein the analysis unit transforms the input image into frequency spatial data other than an image space, and classifies the input image using a spatial pattern of the frequency spatial data.
