Classification: CPC A  G | IPC A  G

Claim 10:
11. A living body detection device, comprising:
a receiver that receives, from at least one non-contact sensor, a measurement result obtained by measuring a detection area with the at least one non-contact sensor;
an extraction circuit that extracts a biological signal from the measurement result;
a counting circuit that counts a number of living bodies present in the detection area based on the biological signal;
an acquisition circuit that acquires a prescribed number of living bodies to be present in the detection area; and
a verification circuit that verifies whether the number of living bodies counted by the counting circuit is equal to the prescribed number and outputs a result of verification,
wherein the at least one non-contact sensor is capable of switching between a directional mode in which the at least one non-contact sensor has directivity and an omnidirectional mode in which the at least one non-contact sensor does not have directivity, and
the living body detection device further comprises a controller that instructs the at least one non-contact sensor to operate in the directional mode when the number of living bodies counted by the counting circuit is not equal to the prescribed number.
