Abstract

An on-vehicle device, which is connected to an external image taking device via the Internet so as to allow communication therebetween, includes a communication section, a reception notification section, a display section, a vehicle stopped state detection section, and a display control section. When the communication section receives an emergency (or call) detection notification from the image taking device, the display control section checks the vehicle stopped state detection section to determine whether or not a vehicle is stopped. If the vehicle is stopped, the display control section receives video data from the image taking device via the communication section for causing the display section to display a video image of the video data. Otherwise, the display control section notifies a user of an emergency (or call) detection notification via the reception notification section.

Claims

1. An on-vehicle device for placement in a vehicle and connection to an external image taking device via the Internet such that the on-vehicle device is able to communicate with the image taking device via the Internet, the external image taking device for detecting an emergency at least within an area in which an image is captured or a call, and transmitting an emergency detection notification or a call detection notification to a previously designated destination when the emergency or the call is detected, respectively, the on-vehicle device comprising:

communication means for communicating with the image taking device via the Internet;

reception notification means for notifying a user, by at least one of blinking of a button, a sound, vibration, and displaying a character or a symbol on a display panel, that the communication means receives an emergency detection notification or a call detection notification from the image taking device;

display means for displaying a video image of video data received by the communication means from the image taking device;

vehicle stopped state detection means for detecting whether or not the vehicle is stopped;

control means for checking the vehicle stopped state detection means to determine whether or not the vehicle is stopped when the communication means receives the emergency detection notification or the call detection notification from the image taking device, receiving the video data from the image taking device via the communication means and causing the display means to display the video image of the video data if the vehicle is stopped, and notifying the user of the emergency detection notification or the call detection notification by the reception notification means if the vehicle is not stopped; and

a video image playback instruction input means for accepting an input of a video image playback instruction from the user, wherein

if the vehicle is not stopped, the control means is operable to receive the video data from the image taking device via the communication means at least when the video image playback instruction input means receives the video image playback instruction, and cause the display means to display the video image of the video data.

2. An on-vehicle device for placement in a vehicle and connection to an external image taking device via the Internet such that the on-vehicle device is able to communicate with the image taking device via the Internet, the external image taking device for detecting an emergency at least within an area in which an image is captured or a call, and transmitting an emergency detection notification or a call detection notification to a previously designated destination when the emergency or the call is detected, respectively, the on-vehicle device comprising:

communication means for communicating with the image taking device via the Internet;

reception notification means for notifying a user that the communication means receives an emergency detection notification or a call detection notification from the image taking device;

display means for displaying a video image of video data received by the communication means from the image taking device;

vehicle stopped state detection means for detecting whether or not the vehicle is stopped;

control means for checking the vehicle stopped state detection means to determine whether or not the vehicle is stopped when the communication means receives the emergency detection notification or the call detection notification from the image taking device, receiving the video data from the image taking device via the communication means and causing the display means to display the video image of the video data if the vehicle is stopped, and notifying the user of the emergency detection notification or the call detection notification by the reception notification means if the vehicle is not stopped; and

a video image playback instruction input means for accepting an input of a video image playback instruction from the user, wherein

if the vehicle is not stopped, the control means is operable to receive the video data from the image taking device via the communication means at least when the video image playback instruction input means receives the video image playback instruction, and cause the display means to display the video image of the video data.

3. The on-vehicle device according to claim 2, wherein

when an emergency or a call is detected, the image taking device transmits a video image playback request signal as the emergency detection notification or the call detection notification, and

the control means is operable to perform a display control operation when the communication means receives the video image playback request signal transmitted from the image taking device.

4. The on-vehicle device according to claim 2, wherein

when an emergency or a call is detected, the image taking device transmits an emergency detection signal or a call detection signal as the emergency detection notification or the call detection notification, respectively, and

the control means is operable to perform a display control operation when the communication means receives the emergency detection signal or the call detection signal from the image taking device.

5. The on-vehicle device according to claim 2, wherein if the vehicle is not stopped and the video image playback instruction input means receives the video image playback instruction within a predetermined time period after the reception notification means notifies the user of reception notification, the control means is operable to receive the video data from the image taking device via the communication means, and cause the display means to display the video image of the video data.

6. The on-vehicle device according to claim 5, further comprising video data storing means for storing the video data received by the communication means from the image taking device, wherein

if the vehicle is not stopped and the video image playback instruction input means does not receive the video image playback instruction within a predetermined time period after the reception notification means notifies the user of reception notification, the control means is operable to receive the video data from the image taking device via the communication means, and cause the video data storing means to store the received video data.

7. The on-vehicle device according to claim 6, wherein, when the vehicle is stopped, the control means is operable to read the video data stored in the video data storing means, and display the read data on the display means.

8. The on-vehicle device according to claim 2, wherein the video image playback instruction input means includes at least one of a button, a key, a touch panel, a speech recognition device, and a remote control device.

9. The on-vehicle device according to claim 2, wherein

the reception notification means is operable to perform reception notification by blinking a button, and

the video image playback instruction input means is operable to accept the video image playback instruction when the blinking button is depressed.
