Abstract

An on-vehicle device is configured to be able to communicate with a mobile device, and includes a reception unit, an interruption detection unit, a determination unit, and a display control unit. The reception unit receives image information transmitted from a particular mobile device which is a mobile device with which communication is established. The interruption detection unit detects that reception of the image information is interrupted. The determination unit determines whether or not the transmission device which transmits the image information is the particular mobile device, when the reception unit receives image information again after interruption of the reception is detected. The display control unit stops displaying the image information transmitted from the transmission device on a display device when the transmission device is determined not to be the particular mobile device.

Claims

1. An on-vehicle device capable of communicating with a mobile device, the on-vehicle device comprising:

a reception unit that receives image information transmitted from a particular mobile device which is the mobile device with which communication is established;

an interruption detection unit that detects that reception of the image information is interrupted;

a determination unit that determines, when the reception unit receives image information again after interruption of the reception is detected, whether or not a transmission device which transmits this image information is the particular mobile device; and

a display control unit that stops, when the transmission device is determined not to be the particular mobile device, displaying the image information, transmitted from the transmission device, on a display device.

2. The on-vehicle device according to claim 1, wherein

the determination unit determines whether or not the transmission device, which transmits the image information received by the reception unit after the interruption of the reception is detected, is a mobile device with which communication is newly established, and

when it is determined that the transmission device is neither the mobile device with which communication is newly established nor the particular mobile device, the display control unit stops displaying the image information transmitted from the transmission device on the display device.

3. The on-vehicle device according to claim 1, further comprising

a reply detection unit that detects a reply from a user, wherein

the image information includes notice information which should be notified to the user, and

when a reply from the user with respect to the notice information displayed on the display device is detected, the determination unit determines that the transmission device is the particular mobile device.

4. The on-vehicle device according to claim 1, further comprising

an authentication information detection unit that detects authentication information included in the image information, wherein

when the authentication information of the image information transmitted from the transmission device is detected, the determination unit determines that the transmission device is the particular mobile device.

5. The on-vehicle device according to claim 1, further comprising

an authentication command detection unit that detects a particular authentication command, wherein

when the authentication command is detected from a signal transmitted from the transmission device, the determination unit determines that the transmission device is the particular mobile device.

8. The on-vehicle device according to claim 2, further comprising

a reply detection unit that detects a reply from a user, wherein

the image information includes notice information which should be notified to the user, and

when a reply from the user with respect to the notice information displayed on the display device is detected, the determination unit determines that the transmission device is the particular mobile device.

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

an authentication information detection unit that detects authentication information included in the image information, wherein

when the authentication information of the image information transmitted from the transmission device is detected, the determination unit determines that the transmission device is the particular mobile device.

10. The on-vehicle device according to claim 2, further comprising

an authentication command detection unit that detects a particular authentication command, wherein

when the authentication command is detected from a signal transmitted from the transmission device, the determination unit determines that the transmission device is the particular mobile device.

6. A communication method of an on-vehicle device capable of communicating with a mobile device, the communication method comprising:

(a) receiving image information transmitted from a particular mobile device which is the mobile device with which communication is established;

(b) detecting that reception of the image information is interrupted;

(c) determining, when image information is received again after interruption of the reception is detected, whether or not a transmission device which transmits this image information is the particular mobile device; and

(d) stopping, when the transmission device is determined not to be the particular mobile device, displaying the image information, transmitted from the transmission device, on a display device.

7. A non-transitory computer readable storage medium having stored therein a program executable by a computer included in an on-vehicle device capable of communicating with a mobile device, the program causing the computer to execute a process comprising:

(a) receiving image information transmitted from a particular mobile device which is the mobile device with which communication is established;

(b) detecting that reception of the image information is interrupted;

(c) determining, when image information is received again after interruption of the reception is detected, whether or not a transmission device which transmits this image information is the particular mobile device; and

(d) stopping, when the transmission device is determined not to be the particular mobile device, displaying the image information, transmitted from the transmission device, on a display device.
