Image diagnostic device, image processing method, and program

An image diagnostic device that obtains a prediction model indicating a higher accuracy diagnosis prediction result through DL includes: an observation unit that collects an image of an examination object; and an image processing unit that generates first image data from the image, and performs image processing of the first image data. The image processing unit is provided with: a feature extraction unit 220 that extracts a first feature from the first image data; a feature transformation unit 230 that converts the first feature to a second feature to be extracted from second image data; and an identification unit 240 that calculates a prescribed parameter value using the converted second feature. The feature extraction unit 220 includes a prediction model learned using a plurality of combinations of the first image data and feature, and the feature transformation unit 230 includes a feature transformation model learned using a plurality of combinations of the first and second features. 本发明利用DL得到以更高精度表示医学妥当性高
