Classification: CPC A  G | IPC A  G

Claim 12:
13. 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 the 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 includes a plurality of non-contact sensors,
each of the plurality of non-contact sensors is capable of switching between an operation mode in which the living body detection device is capable of measuring the detection area and an idle mode in which the living body detection device does not measure the detection area and is ready for measuring the detection area, and
the living body detection device further comprises a controller that instructs, among the plurality of non-contact sensors, a non-contact sensor that has detected the number of living bodies that is not equal to the prescribed number to enter the idle mode.
