Abstract

A display device includes a communicator, a display, an input device, and at least one processor. The communicator communicates the external device. The display displays the first object. The input device receives an input for updating the first object. The at least one processor selects a first mode or a second mode. When the first mode is selected and the first object is shared with the external device, the at least one processor causes the display to update the first object according to the input and causes the communicator to send a first information reverent to updated first object to the external device. When the second mode is selected and the first object is shared with the external device, the at least one processor causes the display to update the first object according to the first input and causes the communicator not to send the first information.

Claims

1. A display device configured to share display of a display object with an external device, the display device comprising:

a display;

an input device; and

at least one processor configured to

switch between a synchronous mode and an asynchronous mode, while in the synchronous mode and while the display object is shared with the external device, when an input for updating the display object is received via the input device, cause the display to update the display object according to the input, and send first information relevant to the updated display object to the external device,

while in the asynchronous mode and while the display object is shared with the external device, when an input for updating the display object is received via the input device, cause the display to update the display object according to the input, but do not send the first information relevant to the updated display object to the external device,

regardless of whether in the synchronous mode or the asynchronous mode, when second information relevant to the display object is received from the external device, cause the display to update the display object according to the second information, and

cancel the update to the display object, which was performed according to the second information received from the external device, after a predetermined period of time has elapsed after the update,

wherein the at least one processor is configured to increase the predetermined period of time every time the input device receives a predetermined input.

2. The display device according to claim 1, wherein the display object comprises one or more of a graphical image and text.

3. The display device according to claim 1, wherein the at least one processor is configured to, while in the asynchronous mode and while the display object is shared with the external device, when the second information is received within a predetermined period of time after receipt of the input, wait until the predetermined period of time lapses before updating the object according to the second information.

4. The display device according to claim 1, wherein the display object comprises a first layer, to be edited at the external device, and a second layer, to be edited at the display device, and wherein the at least one processor is configured to overlay the second layer above the first layer.

5. A processor for a display device configured to share display of an object with an external device, the display device comprising a display, and an input device, the processor configured to:

switch between a synchronous mode and an asynchronous mode;

while in the synchronous mode and while the object is shared with the external device, when an input for updating the object is received via the input device, cause the display to update the object according to the input, and send first information relevant to the updated object to the external device;

while in the asynchronous mode and while the object is shared with the external device, when an input for updating the object is received via the input device, cause the display to update the object according to the input, but do not send the first information relevant to the updated display object to the external device;

while in the asynchronous mode and while the display object is shared with the external device, when second information is received within a predetermined period of time after receipt of the input, determine whether or not the predetermined period of time has passed; and

cause the display to update the display object according to the second information when determining that the predetermined period of time has passed.

6. The processor according to claim 5, wherein the processor is configured to, regardless of whether in the synchronous mode or the asynchronous mode, when second information relevant to the display object is received from the external device, cause the display to update the display object according to the second information.

7. A display device configured to share displaying an object with an external device, comprising:

a display;

an input device; and

at least one processor configured to

switch between a synchronous mode and an asynchronous mode, while in the synchronous mode and while the object is shared with the external device, when an input for updating the object is received via the input device, cause the display to update the object according to the input, and send first information relevant to the updated object to the external device,

while in the asynchronous mode and while the object is shared with the external device, when an input for updating the object is received via the input device, cause the display to update the object according to the input, and send the first information with second information that prevents the external device from updating the object according to the first information,

regardless of whether in the synchronous mode or the asynchronous mode, when third information relevant to the object is received from the external device, cause the display to update the object according to the third information, and

cancel the update to the object, which was performed according to the third information received from the external device, after a predetermined period of time has elapsed after the update,

wherein the at least one processor is configured to increase the predetermined period of time every time the input device receives a predetermined input.
