IMAGING DEVICE AND WIRELESS SYSTEM
First Claim
1. An imaging device comprising:
- an image capturing unit that captures an image;
a display unit that displays the image;
an antenna that is disposed at a position determined in advance with respect to the image capturing unit;
an antenna control unit that controls directivity of the antenna by changing a maximum gain direction of the antenna;
a wireless unit that transmits searching data to one or more wireless terminals through the antenna and receives response data corresponding to the searching data;
a signal intensity detection unit that detects a reception intensity of the response data;
an identification information extraction unit that specifies identification information of the wireless terminal which is a transmission source of the response data;
a recording control unit that generates data sets in which the identification information, the reception intensity, and the maximum gain direction are associated with each other;
a recording unit that records the data sets;
a relative angle extraction unit that extracts the maximum gain direction of the data set having the reception intensity relatively greater than the other reception intensities among the data sets with the same identification information recorded in the recording unit, as a relative angle indicating a relative direction of the wireless terminal relative to the imaging device serving as a reference;
an estimated position calculation unit that calculates an estimated position of the wireless terminal on the display unit based on an angle of view of the display unit, the relative angle, a positional relation between the image capturing unit and the antenna, and the reception intensity; and
a display control unit that performs control such that the display unit displays the image and that superimposes and displays terminal information used to specify the wireless terminal corresponding to the identification information on the estimated position.

Abstract
An imaging device includes: 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.
