Title: ELECTRONIC DEVICE, CONTROL METHOD FOR ELECTRONIC DEVICE, AND CONTROL PROGRAM
Abstract:
In order to stably detect the approach or separation of a user having an external terminal even if there is an obstacle between an electronic device and the user, this electronic device (100) is an electronic device capable of wireless communication with an external terminal (301), and comprises: a control means (203) for controlling transition between an operating state and an operation standby state of the electronic device; and a measurement means (221) capable of measuring communication times required for wireless communication with the external terminal in the operating state and the operation standby state. According to the communication time measured in one state of the operating state and the operation standby state, the control means causes the electronic device to make transition from the one state to the other state.
