The invention provides an imageprocessing device which implements efficiency of an observation by a user and an image processing method in the image processing device with a sorting criterion calculating means for calculating sorting criteria when sorting the images included in a subset.
The invention provides an image processing device which implements efficiency of an observation by a user and an image processing method in the image processing device. The image processing device is equipped with an image signal input means for inputting image signals from a plurality of images captured by a medical device with an imaging feature, an image segmentation means for dividing each of the plurality of images into a plurality of regions, a characteristic amount calculating means for calculating the amount of characteristics in each of the plurality of regions, a cluster sorting means for sorting each of a plurality of clusters generated in a characteristic space into one of a plurality of classes from the amount of the characteristics and the occurrence frequency of the amount of the characteristics, a subset generating means for generating a plurality of subsets by using the plurality of images,; and a sorting criterion calculating means for calculating sorting criteria when sorting the images included in a subset from the distribution state of the characteristic amount in the characteristic space of each image included in a subset.
