  • Patent number: 11864117
    Abstract: An electronic device including a generation unit, a reception unit, a storage unit, and a control unit. The generation unit generates data. The reception unit receives, from an external device, position information related to a position. The storage unit stores the received position information. The control unit determines an elapsed length of time that has passed since the reception unit received the position information. In response to the elapsed length of time being less than a predetermined length of time, the control unit correlates the generated data with the stored position information. In response to the elapsed length of time being greater than or equal to the predetermined length of time, the control unit transmits a request, to the external device, to transmit updated position information, and correlates the generated data with the updated position information.
