An imaging device, a control method, and a program with automatic power-on control in response to contactless communication are disclosed. An imaging preparation operation is performed after the completion of a transmission of connection information for a wireless communication connection. In one example, an imaging device includes a contactless communication part configured to perform contactless communication with an external device, and a control part configured to control power-on/off of the imaging device and an imaging preparation operation. The control part performs control to set the power of the imaging device ON upon detecting a polling command transmitted by the contactless communication from the external device, transmits connection information for wireless communication connection with the external device to the external device after the imaging device is powered on, and performs control such that the imaging preparation operation is performed, when the transmission of the connection information is completed.
