  For example, when a smartphone is connected to the in-vehicle device 10, a synchronization mode for automatically displaying an image displayed on the smartphone as it is on the screen of the in-vehicle device 10 is automatically set. An icon may be generated based on the acquired image. In this case as well, if the user connects the smartphone to the in-vehicle device 10 with the favorite image displayed on the screen of the smartphone, an icon corresponding to the favorite image can be generated and registered. As a result, a favorite icon can be displayed in the search result list by the search process.

  Moreover, you may enable it for a user to select a favorite image arbitrarily as a predetermined image which the vehicle equipment 10 acquires. For example, the image acquisition unit 11 does not acquire a specific image from the mobile phones 100a, 100b, and 100c (may be other mobile devices such as smartphones), but is stored in the internal memory of the mobile phones 100a, 100b, and 100c. The identification information (for example, image file names or icons) of a plurality of images is acquired. Then, a list list using the acquired identification information is displayed on the display unit 20 to prompt the user to select.

  After that, when the user operates the operation unit 30 to select desired identification information from the list, the image acquisition unit 11 uses the identification information selected by the user through the operation of the operation unit 30 as the mobile phone 100a, 100b, 100c is notified, and images corresponding to the identification information are acquired from the mobile phones 100a, 100b, and 100c. Even in this case, since an icon corresponding to the user's favorite image can be generated and registered, the favorite icon can be displayed in the search result list by the search process.

  Moreover, although the said embodiment demonstrated the example which displays the model name and icon of mobile phone 100a, 100b, 100c on a search result list, this invention is not limited to this. As described above, the icon is unique to each mobile phone 100a, 100b, 100c. In addition, if the image is a standby screen, the user of the mobile phone 100a, 100b, 100c is familiar from the usual, and if it is a favorite image, the user himself selects it with his / her own consciousness. Therefore, it is possible to sufficiently recognize which one of the mobile phones 100a, 100b, and 100c displayed as a list is own. Therefore, the model name is not necessarily displayed.

  Moreover, although the said embodiment demonstrated the example with which the display control apparatus of a connected apparatus list was mounted in the vehicle equipment 10, it is not restricted to the vehicle equipment 10. If the electronic device has a Bluetooth communication function, it is possible to mount the connected device list display control device of this embodiment.
