If not, the process returns to S2000. In S2004, when the imaging control unit 52 receives the imaging start signal 520, the imaging unit 51 is controlled to start imaging.

  Thus, according to the eighth embodiment, the same effect as in the seventh embodiment can be obtained, and further, the landscape capturing unit 13 is rotated horizontally in the direction in which the radio wave source comes to the front. There is also an effect that the subject can be searched more quickly.

<Ninth embodiment>
FIG. 18 is a perspective view showing the outer shape of binoculars having a beacon receiving function having a viewer unit as a ninth embodiment. The binoculars include two objective lens units 131 and two eyepiece units 132, and a body 133 to which these are attached. Further, the body 133 is provided with a zoom adjustment unit 134 and a focus adjustment unit 135. . Therefore, the zoom magnification can be adjusted by operating the zoom adjustment unit 134. Furthermore, by operating the focus adjustment unit 135, it is possible to focus on a desired subject in the field of view at that time. In addition, the body 133 is provided with an antenna unit 136 for receiving beacon radio waves and an operation unit 137 for performing operations such as turning on and off the power.

  FIG. 19 is a diagram showing a specific configuration of the binoculars shown in FIG. 18, and the same elements as those in FIG. 18 are denoted by the same reference numerals. Here, the body 133 includes an operation unit 137, a central processing unit 141, an information display unit 142, a power supply unit 143, a position detection unit 146, an orientation detection unit 147, a beacon reception unit 148, and a signal generation unit 149. Yes. A prism unit 145 and a superimposing unit 144 are provided between the objective lens unit 131 and the eyepiece lens unit 132.

  Here, the central processing unit 141 is configured by a data recording device, a CPU, various programs, etc. (not shown). As the position detection unit 146, for example, a GPS receiver can be used. As the direction detection unit 147, for example, an electronic compass can be used. The beacon receiving unit 148 receives beacon radio waves from the antenna unit 136.

  Here, it is assumed that a beacon transmitter (not shown) can add various information to the transmitted radio wave. As shown in FIG. 20, this data can be added using amplitude phase modulation, and by using binary amplitude modulation and binary phase modulation, 2-bit data per symbol can be transmitted. it can. For example, 4-symbol data can be added to the beacon radio wave, the first 1 symbol can be used as signal data, and the other 3 symbols can be used as user data. The beacon receiver 148 of the beacon receiver demodulates the radio wave received by a detection method such as synchronous detection. By setting the identification ID of the beacon transmitter in advance, the beacon transmitter adds its own identification ID to the beacon radio wave, and the beacon receiver can identify a plurality of beacon transmitters.

  FIG. 21 is an explanatory diagram of the information superimposing operation of the superimposing unit 144, and superimposing information 153 shown in (c) is obtained by superimposing the captured image 151 shown in (a) and the visible information 152 shown in (b). It is shown that. The captured image 151 is captured from the objective lens unit 131 shown in FIG. The visible information 152 includes direction information 152a indicating the direction of the beacon radio wave transmission source and distance information 152b indicating the distance. The distance information 152b may be a radio wave intensity. When the distance information 152b is a distance, it can be represented by a meter, and when it is a radio wave intensity, it can be represented by dBm. A captured image 151 is captured from the objective lens unit 131 shown in FIG. Since the captured image 151 taken upside down is inverted, it is corrected in the correct direction using the prism unit 145. The central processing unit 141 creates visible information 152 using the beacon radio wave received by the beacon receiving unit 148 and adds it to the information display unit 142. The information display unit 142 is a liquid crystal monitor or the like, and adds the visible information 152 created by the central processing unit 141 to the superimposing unit 144. The superimposing unit 144 is formed of a half mirror, and superimposing information 153 obtained by superimposing the captured image 151 and the visible information 152 added thereto is added to the eyepiece unit 132, and the device user looks into the eyepiece unit 132. Superimposition information 153 can be seen. The superimposing unit 144 can use a half mirror, but the reflectance may be greater than 50% so that the captured image 151 does not appear dark.

  In order to create the direction information 152a shown in FIG. 21, it is necessary to detect the radio wave arrival direction of the beacon radio wave. In order to detect the radio wave arrival direction, the antenna unit 136 uses a plurality of directional antennas. As the directional antenna, for example, a Yagi antenna can be used. As shown in FIG. 6, the directional antennas are installed in different directions. The antenna unit 136 is recorded with a pair of information indicating the direction in which the antenna unit faces and the beacon receiving unit 148 identifies each antenna. The beacon receiving unit 148 switches the antenna to receive periodically, and adds the received radio wave intensity of each antenna to the central processing unit 141. The central processing unit 141 detects the direction in which the antenna that outputs the highest received radio wave intensity is facing as the radio wave arrival direction, and creates direction information 152a suitable for that direction. Further, the distance information 152b is created from the received radio wave intensity received by the antenna, and the visible information 152 including the information is added to the information display unit 142.

  As shown in FIG. 8, the antenna unit 136 may include a motor 124 that rotates horizontally, and the antenna unit 136 may be a single antenna having high directivity. It is assumed that the motor 124 included in the antenna unit 136 includes a sensor that detects the direction in which the antenna is facing and can detect the direction in which the antenna is facing. By rotating the antenna unit 136 horizontally, the same effect as that provided when a plurality of antennas are provided can be obtained. The central processing unit 141 detects the direction in which the antenna unit 136 is directed from the beacon receiving unit 148, samples and records the received radio wave intensity in each direction, and the direction in which the received radio wave intensity is the highest is the radio wave. Determine the direction of arrival.

  In order to detect the direction of the beacon transmitter, the antenna unit 136 not only physically controls the direction of directivity but also a phased array antenna 121 capable of electronically controlling directivity as shown in FIG. Alternatively, the phase shift control device 122 may be used. The phase shift control device 122 periodically changes the direction of directivity of the antenna unit 136 to the left and right, and receives radio waves from each direction. The beacon receiving unit 148 detects the direction information that the antenna unit 136 faces from the phase shift control device 122 and adds the received radio wave intensity and the direction information to the central processing unit 141. The central processing unit 141 detects the direction with the highest received radio wave intensity.

  Here, the direction information 152a of the visible information 152 may be the arrow shown in FIG. 21, but as shown in FIG. 22, it indicates which beacon transmitter is in the direction in which the beacon receiver is facing. May be.

  In addition, the direction information 152a may indicate the relationship between the received power values of a plurality of antennas as shown in FIG. FIG. 23 shows the distance from the mark indicating the reference direction to the mark indicating the antenna as the received radio wave intensity, and indicates that the direction of the antenna far from the mark indicating the reference direction may be pointed.

  Furthermore, as another method, the visible information 152 may be created using the position detection unit 146 and the orientation detection unit 147 shown in FIG. In this case, the beacon transmitter adds position information to the beacon radio wave. Binoculars that are beacon receivers include a position detection unit 146 and an orientation detection unit 147. The position detection unit 146 adds the longitude and latitude information of the current position to the central processing unit 141, and the azimuth detection unit 147 detects the direction of the reference direction toward the objective lens unit 131 and adds the detected direction to the central processing unit 141. As the position detection unit 146, for example, a GPS receiver can be used, or the user may directly input from the operation unit 137. The direction detection unit 147 can use an electronic compass, for example. The beacon receiving unit 148 demodulates the beacon radio wave received by the antenna unit 136 and adds longitude and latitude information to the central processing unit 141. The central processing unit 141 detects the relative positions of the longitude and latitude of each other from the orientation that is facing the longitude and latitude of the beacon receiver and the longitude and latitude of the beacon transmitter. From the detected relative position, distance and azimuth are detected, and further, which direction is detected from the azimuth facing and the azimuth of the beacon transmitter. The distance is calculated using the above equation (1). The central processing unit 141 creates visible information 152 shown in FIG. 21 from the detected distance and direction.

  As a distance detection method, there is also a method of detecting a distance from a delay time of radio wave transmission / reception. In this case, the signal generation unit 149 generates a distance measurement transmission signal 410, and the signal generation unit 149 applies the distance measurement transmission signal 410 to the antenna unit 136 and the central processing unit 141. The central processing unit 141 records the time when the distance measurement transmission signal 410 is added. The antenna unit 136 transmits the distance measurement transmission signal 410 as a radio wave. It is assumed that the transmission device held by the subject returns the distance measurement reply signal 411 immediately upon receiving the distance measurement transmission signal 410. The central processing unit 141 takes a difference between the time at which the distance measurement reply signal 411 is received and the time at which the distance measurement transmission signal 410 is transmitted, and converts this difference into a distance in consideration of the speed of radio waves. The central processing unit 141 creates distance information 152b shown in FIG. 21 from the converted distance. The central processing unit 141 stores in advance information on the time taken from the reception of the distance measurement transmission signal 410 to the transmission of the distance measurement reply signal 411 for the beacon transmitter.

  The visible information 152 displayed by the information display unit 142 can be changed by operating the operation unit 137. For example, a display setting screen 161 shown in FIG. 24A can be displayed on the information display unit 142. By selecting the direction display setting from the display setting screen 161, the direction display setting screen 162 shown in FIG. 24B can be displayed on the information display unit 142, and it is selected whether the direction information 152a is displayed or not. be able to. Further, by selecting the intensity display setting from the display setting screen 161, the intensity display setting screen A163a shown in FIG. 24C can be displayed on the information display unit 142, and whether the distance information 152b is displayed or not is displayed. You can choose. Furthermore, when the display is selected in the intensity display setting, the intensity display setting screen B163b shown in FIG. 24D can be displayed on the information display unit 142, and the display of the radio field intensity information to be displayed is selected or not displayed. The radio wave intensity information 152c to be displayed can be changed from the radio wave intensity to the distance, and a numerical value or a graph can be selected. Furthermore, various settings other than these can be made.

  As described above, according to the ninth embodiment, it is possible to eliminate the troublesomeness of looking at a receiving device or looking at binoculars in order to search for a subject having a beacon transmitter. Binoculars having a beacon receiving function that can determine whether an object can be searched by turning the direction and can quickly search for a subject are provided.
