1. 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;
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; and
at least one of a processor or a circuit that moves the at least one non-contact sensor when the number of living bodies counted by the counting circuit is not equal to the prescribed number.
