TRAINING DEVICE, BIOMETRIC DATA ESTIMATING DEVICE, TRAINING METHOD AND BIOMETRIC DATA ESTIMATING METHOD

Abstract

A training device (100) includes: a luminance data acquisition unit (110) that acquires time-series luminance data based on time-series imaging data; a true-value data acquisition unit (120) that acquires time-series true-value data using time-series biometric reference information based on a biometric signal; a time-difference correction unit (130) that corrects a time difference between the time-series luminance data and the time-series true-value data; and a model training unit (140) that constructs a trained model to output biometric data from the time-series luminance data, using the time-series luminance data and the time-series true-value data output by the time-difference correction unit.
