Abstract
A display apparatus includes a USB connector used to connect an external device so as to be able to communicate with that device. The display apparatus also includes a CPU which controls to make a display based on data received from the external device with which a communication connection is established via the USB connector. The CPU acquires class information indicating a class of the external device, the communication connection of which is established. When the communication connection with the external device is disconnected, if the acquired class information indicates a predetermined class, the CPU controls to continue the display based on the received data, and if the class information does not indicate the predetermined class, the CPU controls to end the display.
Claims14
A display control apparatus comprising:
- a communication unit configured to communicate with an external device;
- and
- a display control unit configured to display, on a display unit, an image received from the external device via the communication unit, and if communication with the external device is disconnected, to stop the display of the image received from the external device,
- wherein the display control unit varies a period of time from the disconnection to the stopping of the display of the image depending on a type of the external device.
A display control apparatus comprising:
- a communication unit configured to communicate with an external device;
- and
- a display control unit configured to display, on a display unit, an image received from the external device via the communication unit, and if communication with the external device is disconnected, to stop the display of the image received from the external device,
- wherein the display control unit varies a period of time from the disconnection to the stopping of the display of the image depending on a determination result as to whether the disconnection of the communication with the external device is a physical disconnection or a logical disconnection.
A control method of a display control apparatus having a communication unit configured to communicate with an external device, the method comprising:
- a display control step of displaying, on a display unit, an image received from the external device via the communication unit, and if communication with the external device is disconnected, stopping the display of the image received from the external device,
- wherein the display control step varies a period of time from the disconnection to the stopping of the display of the image depending on a type of the external device.
A control method of a display control apparatus having a communication unit configured to communicate with an external device, the method comprising:
- a display control step of displaying, on a display unit, an image received from the external device via the communication unit, and if communication with the external device is disconnected, stopping the display of the image received from the external device,
- wherein the display control step varies a period of time from the disconnection to the stopping of the display of the image depending on a determination result as to whether the disconnection of the communication with the external device is a physical disconnection or a logical disconnection.
