Abstract
A pulse wave measuring apparatus includes a light emitter that illuminates with light having an amount an area containing a part of skin of a user staying in a vehicle, an imager that captures an image of the area, a controller that obtains a driving route from a departure point of the vehicle to a destination point of the vehicle, obtains an estimated time at which the vehicle passes through a location along the driving route, predicts an incident amount of sun light that enters the vehicle at the location at the estimated time, and calculates the amount under a condition that a sum of the predicted incident amount and the amount is a constant value, and a pulse wave calculator that calculates a pulse wave of the user using the image, and outputs pulse wave information of the user.
