摘要
A medical image compression device includes: a compression target obtaining unit obtaining a target medical image to be compressed and diagnostic finding information for the target image; a clinical condition range obtaining unit dividing the target image into regions for the respective clinical conditions based on the diagnostic finding information; a pixel value prediction unit, for an arbitrary pixel, referring to a prediction knowledge database, and calculating a prediction probability of a value of a prediction target pixel based on the clinical condition of the prediction target pixel and the appearance distribution of the value of the prediction target pixel; a coding unit coding the value of the prediction target pixel based on the prediction probability of the pixel value; and an output unit outputting a code of the prediction target pixel after being coded by the coding unit.
