Connection device, display device, and control method for the display device
A connection device connected to an image display unit that is head-mounted includes a connector to which an image signal is input; and a connector to which an image signal is input and which is capable of outputting sensor data. The connection device further includes a setting unit that sets a selection between the image signals; and an output control unit that selects the connector for outputting the image signal by a connection unit according to the setting. The setting unit sets the image signal to be output from the connection unit when the image signal is input.
1. A connection device connected to a display device that is head-mounted, the connection device comprising:
a first connection unit to which a first image signal is input;
a second connection unit to which a second image signal is input, and which is configured to perform at least one of input and output of data relating to an input device included in the display device;
an output unit configured to output to the display device one of the first image signal input to the first connection unit and the second image signal input to the second connection unit;
a setting unit configured to set a selection between the first image signal and the second image signal; and
an output control unit configured to select a connection unit that outputs an image signal by the output unit according to the setting by the setting unit, wherein
the setting unit sets the first image signal input to the first connection unit to be output from the output unit when image signals are input to both of the first connection unit and the second connection unit.
2. The connection device according to claim 1 , wherein
the setting unit changes the setting of the selection between the first image signal and the second image signal based on a history of outputting the first image signal to the display device by the output unit and a history of outputting the second image signal to the display device by the output unit.
3. The connection device according to claim 2 , wherein
the setting unit counts an output time of outputting the first image signal to the display device by the output unit and an output time of outputting the second image signal to the display device by the output unit, and changes the setting of the selection between the first image signal and the second image signal based on a length of the output time.
4. The connection device according to claim 3 , comprising:
a detecting unit configured to detect a first external device connected to the first connection unit and a second external device connected to the second connection unit, wherein
the setting unit counts the output time of outputting the first image signal to the display device by the output unit in association with the first external device, and counts the output time of outputting the second image signal to the display device by the output unit in association with the second external device.
5. A display device that is head-mounted comprising:
an image display unit configured to display an image;
a first connection unit to which a first image signal is input;
a second connection unit to which a second image signal is input and which is configured to perform at least one of input and output of data relating to an input device included in the image display unit;
an output control unit configured to display an image by the image display unit based on one of the first image signal input to the first connection unit and the second image signal input to the second connection unit; and
a setting unit configured to set a selection between the first image signal and the second image signal, wherein
the output control unit selects one of the first connection unit and the second connection unit according to the setting by the setting unit, and displays an image by the image display unit, and
the setting unit sets the first image signal to be input to the first connection unit to be selected when image signals are input to both of the first connection unit and the second connection unit.
6. A control method for a display device that is head-mounted and includes an image display unit configured to display an image, a first connection unit to which a first image signal is input, and a second connection unit to which a second image signal is input and which is configured to perform at least one of input and output of data relating to an input device included in the image display unit, the control method comprising:
setting a selection between the first image signal and the second image signal;
selecting one of the first connection unit and the second connection unit according to the setting;
displaying an image by the image display unit based on an image signal selected from the first image signal input to the first connection unit and the second image signal input to the second connection unit; and
setting the first image signal input to the first connection unit to be selected when image signals are input to both of the first connection unit and the second connection unit.
