Abstract
A pulse wave measuring apparatus is provided, the pulse wave measuring apparatus including: a cardiac pulse waveform information acquiring unit that optically acquires cardiac pulse waveform information from a region of a living body; and a pulse wave feature amount calculating unit that calculates a pulse wave feature amount based on the pulse waveform information, wherein the pulse waveform information acquiring unit has a video input unit that receives an input of a video of the region of the living body, and the pulse waveform information acquiring unit outputs a window signal that includes first sample data from the pulse waveform information, and outputs, from the video, the window signal whose sampling rate is fixed to a predetermined rate based on a reference signal indicating time.
