Display control device

1. A display control device, comprising:

a communication unit that performs communication with an external device;

a detecting unit that detects a direction of motion of an operation device based on detection information representing the motion of the operation device along the direction and an amount of change in direction of the motion of the operation device along the direction; and

a display control unit that generates an imaging control command based on the detected direction of the motion of the operation device and a result of comparing the amount of change in direction of motion with a threshold value corresponding to the amount of change in direction of motion, and controls an image obtained through an imaging operation of a virtual imaging device by transmitting, via the communication unit, the imaging control command to the external device, wherein the display control unit performs a plurality of transmissions of the imaging control command to the external device when the amount of change in direction of the motion of the operation device is greater than or equal to the threshold value,

wherein the external device executes the imaging control command to control the imaging operation by the virtual imaging device.

2. The display control device according to claim 1 ,

wherein the detecting unit further detects an amount of change in position of the operation device, and

the display control unit generates the imaging control command based on the detected amount of change in position.

3. The display control device according to claim 2 , wherein the display control unit generates the imaging control command based on a result of comparing the amount of change in position with a threshold value corresponding to the amount of change in position.

4. The display control device according to claim 1 ,

wherein the detection information includes a pressure value that changes according to a user's operation, and

the display control unit selectively generates the imaging control command based on a result of comparing the pressure value with a threshold value corresponding to the pressure value.

5. The display control device according to claim 1 , wherein the detection information includes a value representing acceleration, a value representing an angular velocity, and a value representing magnetic strength.

6. The display control device according to claim 1 , wherein the imaging control command is used to control an imaging operation of an image imaged in the past in the virtual imaging device.

7. The display control device according to claim 1 , wherein the imaging control command is used to control an imaging operation of an image drawn in a virtual space in the virtual imaging device.

8. The display control device according to claim 1 , wherein the operation device is a spherical device which is held and used.

9. The display control device according to claim 1 , wherein the communication unit continues to transmit the imaging control command to the external device until a predetermined stop operation is performed by a user on the operation device.

10. The display control device according to claim 1 , wherein the communication unit stops transmission of the imaging control command to the external device if the display control unit determines that the external device cannot perform processing corresponding to the imaging control command.

11. The display control device according to claim 1 , wherein the display control unit controls display of the image on a display screen and the image displayed on the display screen changes in response to transmission of the imaging control command to the external device.

12. The display control device according to claim 11 , wherein the image on the display screen changes in response to each transmission of the imaging control command to the external device.

13. The display control device according to claim 1 , wherein the communication unit continues to transmit the imaging control command to the external device until a stop button is pressed.

14. The display control device according to claim 1 , wherein the communication unit continues to transmit the imaging control command to the external device until it is difficult for the external device to process the imaging control command.

15. A display control device, comprising:

a communication unit that performs communication with an external device;

a detecting unit that detects a direction of motion of an operation device based on detection information representing the motion of the operation device along the direction and an amount of change in direction of the motion of the operation device along the direction; and

a display control unit that generates an imaging control command based on the detected direction of the motion of the operation device and a result of comparing the amount of change in direction of motion with a threshold value corresponding to the amount of change in direction of motion, and controls an image obtained through an imaging operation of an imaging device by transmitting, via the communication unit, the imaging control command to the external device, wherein the display control unit performs a plurality of transmissions of the imaging control command to the external device when the amount of change in direction of the motion of the operation device is greater than or equal to the threshold value,

wherein the external device connects with the imaging device or the external device is the imaging device, and wherein the imaging control command is used to control an imaging operation of an image imaged in the past in a virtual imaging device.
