Enabling clear indication as to whether or not a myocardial infarction is developed in a portion where cardiac function is deteriorated at the time of image diagnosis of a cardiac region. Using a three-dimensional medical image representing a heart as input, cardiac function analysis unit (31) calculates a cardiac function evaluation value representing a cardiac function with respect to each of predetermined portions of the heart, using a three-dimensional medical image representing the heart as input, myocardial infarction analysis unit (32) calculates a myocardial infarction rate representing a degree of myocardial infarction with respect to each of predetermined portions of the heart, and superimposed image output unit (34) outputs a superimposed image representing the cardiac function evaluation value and the myocardial infarction rate in a superimposing manner such that they are distinguishable from each other in a coordinate system capable of representing each position of the heart in the three-dimensional medical image.
