PULSE WAVE DETECTOR

A pulse wave detection device according to the present disclosure technology is a pulse wave detection device that detects a pulse wave from an image obtained by imaging a subject, and includes an inter-region data adjusting unit including a phase calculating unit and a phase correcting unit. The phase calculating unit calculates a phase difference between a plurality of time-series luminance signals of a region of interest of the image, and the phase correcting unit corrects a phase of the time-series luminance signal on the basis of the calculated phase difference.
