    • An imaging device which has: an imaging unit that captures images; a display unit that displays the images; an antenna arranged at a predetermined position relative to the imaging unit; an antenna control unit that changes the direction of maximum gain for the antenna and controls the directionality of the antenna; a wireless unit that, via the antenna, transmits search data to at least one wireless terminal and receives response data in relation to the search data; a signal strength detection unit that detects the reception strength of the response data; an identification information extraction unit that identifies identification information for the wireless terminal that is the transmission source for the response data; a record control unit that generates data sets associating the identification information, the reception strength, and the direction of maximum gain; a recording unit that records the data sets; a relative angle extraction unit that extracts, as a relative angle indicating the relative direction of the wireless terminal that uses the imaging device as a reference, the direction of maximum gain for the data set having a relatively greater reception strength than others among data sets having the same identification information recorded in the recording unit; an estimated position calculation unit that calculates the estimated position of the wireless terminal in the display unit, on the basis of the angle of view of the display unit, the relative angle, the positional relationship between the imaging unit and the antenna, and the reception strength; and a display control unit that causes images to be displayed in the display unit and also causes terminal information identifying the wireless terminal corresponding to the identification information to be displayed superimposed at the estimated position.
