Abstract
Provided are a method and system for detecting frequency-domain cardiac information, the method comprising: acquiring moving images of a pupil from a subject; extracting a pupil size variation (PSV) from the moving images; extracting a heart rate variability (HRV) spectrum by performing a processing procedure including frequency-analysis of HRV; and calculating power of at least one of a plurality of frequency bands by analysis of the HRV spectrum.
