Abstract
A pulse detector 100 includes a pulse information calculation unit 120 which calculates pulse information on the basis of a pulse wave detection signal from a pulse wave detection unit 10 having a pulse wave sensor 11 and a body motion detection signal from a body motion detection unit 20 having a body motion sensor, a determination unit 112 which determines the exercise state of a subject, and a control unit 150 which controls at least one of a pulse wave sensing operation in the pulse wave detection unit 10, a body motion sensing operation in the body motion detection unit 20, and a calculation processing rat in the pulse information calculation unit 120 on the basis of the determination result of the exercise state in the determination unit 112.
Claims20
A pulse detector comprising:
- a pulse information calculation unit which calculates pulse information on the basis of a pulse wave detection signal from a pulse wave detection unit and a body motion detection signal from a body motion detection unit;
- a determination unit which determines whether a subject is exercising or in living activity;
- and
- a control unit which performs at least two of control for lowering an operation rate of a pulse wave sensing operation, control for lowering an operation rate of a body motion sensing operation, and control for lowering a calculation processing rate when the determination unit determines that the subject is in living activity compared to when it is determined that the subject is exercising.
A program which causes a computer to function as:
- a pulse information calculation unit which calculates pulse information on the basis of a pulse wave detection signal from a pulse wave detection unit and a body motion detection signal from a body motion detection unit;
- a determination unit which determines whether a subject is exercising or in living activity;
- and
- a control unit which performs at least two of control for lowering an operation rate of a pulse wave sensing operation, control for lowering an operation rate of a body motion sensing operation, and control for lowering a calculation processing rate when the determination unit determines that the subject is in living activity compared to when it is determined that the subject is exercising.
