FIG. 1 is a diagram for explaining a mobile phone 100 according to Embodiment 1 of the present invention. FIG. 1A is a schematic diagram showing a system including a mobile phone 100 and a network camera 200 remotely operated by the mobile phone 100. FIG. 1B is a block diagram showing the configuration of the mobile phone 100.

  As shown in FIGS. 1A and 1B, the mobile phone 100 of this embodiment includes a communication unit 123 connected to the network camera 200 via a network 300 such as the Internet. The communication means 123 typically includes an antenna.

  The mobile phone 100 has a first housing 120 and a second housing 127. The first casing 120 and the second casing 127 are connected to each other via a hinge 124. The second casing 127 rotates relative to the first casing 120 about a first axis AX1 passing through the hinge 124 in the longitudinal direction of the hinge 124. Further, the second casing 127 rotates relative to the first casing 120 about the second axis AX2 passing through the hinge 124 in the short direction of the hinge 124. The first axis AX1 and the second axis AX2 are substantially orthogonal. The mobile phone 100 has a foldable biaxial rotating structure. Note that the mobile phone 100 in FIG. 1A is rotated approximately 90 degrees around the first axis AX1 from the state in which the first casing 120 and the second casing 127 are folded, The figure shows a state of being rotated about 90 degrees around the two axes AX2.

  The second casing 127 is provided with a display unit 135. The display unit 135 displays an image based on video information received from the network camera 200 using the communication unit 123.

  Since a still image or a moving image captured by the network camera 200 can be transmitted to the mobile phone 100 via the network 300, an image captured by the network camera 200 can be displayed on the mobile phone 100.

  The cellular phone 100 includes a rotation direction and a rotation angle of the second casing 127 centered on the first axis AX1 relative to the first casing 120, and a second axis AX2 centered on the second axis AX2 relative to the first casing 120. 2 has a detector 137 that detects the rotation direction and rotation angle of the two casings 127. The cellular phone 100 further includes a signal generation unit 144 that generates a signal based on the output result from the detection unit 137.

  The cellular phone 100 transmits the signal to the network camera 200 using the communication unit 123. The network camera 200 receives a signal and is operated based on the signal. Specifically, for example, the swing direction (shooting direction) and the swing speed of the network camera 200 are operated based on the signal. That is, the user of the mobile phone 100 can view the video taken by the network camera 200 on the display unit 135 while viewing the video taken by the network camera 200 even when the user is away from the place where the network camera 200 is installed. The swing speed can be freely controlled.

  As described above, the mobile phone 100 according to the present embodiment has the rotation direction and the rotation angle of the second casing 127 centered on the first axis AX1 and the second axis AX2 centered on the first casing 120. The rotation direction and the rotation angle of the second casing 127 to be detected are detected, the signal generated based on the detection result is transmitted to the network camera 200, and the network camera 200 is remotely operated based on this signal. Compared to the above-mentioned Patent Document 1 that requires key operation, the network camera 200 can be remotely operated with a simple operation.

  FIG. 10 shows a mobile phone 3 that can remotely operate the network camera 2 without a key operation as a comparative example. This cellular phone 3 is disclosed in Japanese Patent Application Laid-Open No. 2004-128997. The video taken by the network camera 2 is transmitted to the mobile phone 3 via the server 1, and the user of the mobile phone 3 can see the video on the display unit of the mobile phone 3. By moving the position of the mobile phone 3 from the position a to the position b and changing the direction of the mobile phone, the shooting direction of the network camera 2 can be moved to a desired direction (position A to position B). Since this conventional remote control method requires a space for changing the direction of the mobile phone 3 and a space for changing the posture of the user accordingly, the portable terminal is used in a narrow place or a crowded place. 3 cannot be changed and it is difficult to change the shooting direction of the remote camera 2.

  If the video server 500 is connected to the mobile phone 100 in step S71 and the playback video of the video server 500 is being played back by the mobile phone 100, the process proceeds to step S72.

  If the connection between the video server 500 and the mobile phone 100 is not disconnected (No in step S72), the process proceeds to S74. In S74, the video server 500 receives the signal generated by the signal generation unit 144 of the mobile phone 100.

  If the received signal contains the signal D0 and the signal D0 is a signal indicating Up or Down direction information (Yes in step S75), the process proceeds to S77.

  In S77, if A0 is included in the received signal (Yes in step S77), the process proceeds to S78. In S78, the video server 500 generates a signal V0 indicating the playback speed of the video server 500 based on the signal A0 indicating the angle information (S78). Next, the process proceeds to S79, and a signal M0 indicating the reproduction direction of the video server 500 is generated based on the signal D0 indicating the rotation direction. The relationship between the signal D0 and the signal M0 is, for example, when the signal D0 is in the Up direction, the signal M0 is in the same direction as the normal playback direction, and when the signal D0 is in the Down direction, the signal M0 is in the opposite direction to the normal playback direction. is there. That is, in step S79, fast forward playback or fast reverse playback of the video server 500 is performed.

  If the signal A0 is not included in the received signal and the signal A1 is included (No in step S77, Yes in step S80), the process proceeds to S81. In S81, the video server 500 generates a signal V1 (V1> V0) indicating the playback speed of the video server 500 based on the signal A1 (S81). Next, the process proceeds to S82, and similarly to S79, a signal M0 indicating the reproduction direction of the video server 500 is generated based on the signal D0 indicating the rotation direction. That is, in step S79, fast forward playback or fast reverse playback is performed at a higher speed than in step S77.

  If neither the signal A0 nor the signal A1 is included in the received signal and the signal A2 is included (No in step S77, No in step S80, step S83), the process proceeds to S84.

  In S84, the video server 500 generates a signal V2 indicating the playback speed of the video server 500 based on the signal A2 (S81). Here, V2 is a normal reproduction speed. That is, in step S84, reproduction is performed in a normal direction at a normal speed.

  In step S75, even if the signal D0 is included in the received signal, the signal D0 is not a signal indicating that the rotation direction is Up or Down, or the signal D0 is not included in the received signal. (No in step S75), the process proceeds to S76. In S76, the video server 500 performs the function selection operation while continuing the reproduction operation. Specifically, for example, a signal indicating any one of slow reproduction, frame advance reproduction, and erasure of reproduced video is generated.

  As described above, the mobile phone 100 according to the present embodiment has the rotation direction and the rotation angle of the second casing 127 centered on the first axis AX1 and the second axis AX2 centered on the first casing 120. The rotation direction and the rotation angle of the second casing 127 to be detected are detected, a signal generated based on the detection result is transmitted to the video server 500, and the video server 500 is remotely operated based on this signal. Compared with the above-mentioned Patent Document 1 that requires key operation, the video server 500 can be remotely operated with a simple operation.

  The present invention is useful for a portable terminal that remotely controls video equipment such as a network camera and a video server.
