Title: HEART RATE ESTIMATION APPARATUS
Abstract:
This heart rate estimation apparatus (1000) includes: a region of interest detection unit (101) that detects a region of interest which includes a face region of a subject from images (110) in which the subject has been imaged sequentially by an imaging device (C1); a luminance calculation unit (102) that calculates a luminance for each light wavelength component in the region of interest; a heart rate component enhancing unit (103) that performs an independent component analysis on the luminance using, in an unmixing matrix of the independent component analysis, heart rate component enhancing coefficients in which the weighting of the luminance coefficients for a green light wavelength component is increased and extracts a heart rate component; and a heart rate calculation unit (104) that calculates the heart rate from the heart rate component.
