1. A human body detecting system, comprising: a mobile communication device; a stand; and a false detection reducing unit, wherein the mobile communication device includes a communication unit for performing communication, the stand includes a human sensor for detecting a human body based on an ambient temperature distribution, and a storage unit for storing detection information of the human sensor, the false detection reducing unit is configured to perform false detection reducing processing on at least one of the detection information of the human sensor and operation of the human sensor, and the false detection reducing unit is configured to determine whether it is a situation in which a false detection by the human sensor is likely to occur based on a communication state of the mobile communication device, and perform the false detection reducing processing on the operation of the human sensor when it is determined that it is the situation in which the false detection is likely to occur due to the mobile communication device being in the communication state.
