Abstract
An apparatus of displaying an image connects an external device by using universal serial bus (USB) connection. The apparatus contains a display unit and a control unit that reads device information out of the connected external device and performs display control on the display unit based on the read device information. Under control of the control unit, the display unit displays a message that is used for changing a class of the external device to a class previously specified in the apparatus of displaying the image when the class of the external device is changeable and it is determined based on the device information that the set class of the external device is different from the class previously specified in the apparatus of displaying the image.

An image displaying apparatus, which connects to an external device using universal serial bus (USB) connection, the image displaying apparatus comprising:
- a display unit;
- and
- a control unit that reads device information out of the connected external device and performs display control on the display unit based on the read device information,
- wherein under control of the control unit, the display unit displays a message that is used for changing a set class of the external device to a class previously specified in the image displaying apparatus when the external device is capable of performing external device class changeover and based on the device information the set class of the external device is determined to be different from the class previously specified in the image displaying apparatus,
- wherein the displayed message notifies a user that connection processing of the external device is being executed in the image displaying apparatus, notifies the user to change connection setting of the connected external device, and to check the connection setting of the connected external device, and
- wherein the control unit determines that the external device is capable of performing external device class changeover if vendor identification contained in the device information is identical to vendor identification previously specified in the image displaying apparatus, which is identification of a vendor who presents external devices capable of performing external device class changeover.
A method of displaying an image in an image displaying apparatus that connects to an external device using USB connection, the method comprising the steps of:
- reading device information out of the external device;
- and
- displaying a message that is used for changing a set class of the external device to a class previously specified in the image displaying apparatus when the external device is capable of performing external device class changeover and based on the device information the set class of the external device is determined to be different from the class previously specified in the image displaying apparatus,
- wherein the displayed message notifies a user that connection processing of the external device is being executed in the image displaying apparatus, notifies user to change connection setting of the connected external device, and to check the connection setting of the connected external device, and
- wherein the external device is determined to be capable of performing external device class changeover if vendor identification contained in the device information is identical to vendor identification previously specified in the image displaying apparatus, which is identification of a vendor who presents external devices capable of performing external device class changeover.
