FEATURE OUTPUT MODEL GENERATION SYSTEM, FEATURE OUTPUT MODEL GENERATION METHOD, FEATURE OUTPUT MODEL GENERATION PROGRAM, AND FEATURE OUTPUT MODEL

A feature quantity output model generation system is a system for generating a feature quantity output model to which information based on an image is input and which outputs a feature quantity of the image, and includes: a learning image acquisition unit that acquires a plurality of learning images associated with focal position information related to a focal position at the time of imaging; and a feature quantity output model generation unit that generates a feature quantity output model by machine learning from the acquired learning images, wherein the feature quantity output model generation unit compares the feature quantities of two different learning images according to focal position information associated with the two different learning images and performs machine learning based on the comparison result.
