Abstract

An information processing apparatus includes circuitry configured to: control an imaging device to stop a first focus adjustment when a specific object is detected from a first image captured by the imaging device while the first focus adjustment is in execution, the first focus adjustment being performed at each first time interval by the imaging device, and control the imaging device to start a second focus adjustment when the specific object is not detected from a second image captured by the imaging device after the imaging device is controlled to stop the first focus adjustment.

First claim

What is claimed is:

1. An information processing apparatus comprising:
circuitry configured to:
control imaging circuitry to stop a first focus adjustment when a specific object is detected from a first image captured by the imaging circuitry while the first focus adjustment is in execution, the first focus adjustment being performed at each first time interval by the imaging circuitry,
control the imaging circuitry to start a second focus adjustment when the specific object is not detected from a second image captured by the imaging circuitry after the imaging circuitry is controlled to stop the first focus adjustment, and
control to display a content to be superimposed over the first image, the content being acquired in accordance with the detected specific object,
wherein the second focus adjustment is performed at each second time interval which is different from the first time interval.

2. The information processing apparatus according to claim 1 , wherein the second time interval is shorter than the first time interval.

3. The information processing apparatus according to claim 2 , wherein the circuitry is configured to:
control the imaging circuitry to restart the first focus adjustment when the specific object is not detected from a plurality of images which are captured by the imaging circuitry after the imaging circuitry is controlled to start the second focus adjustment.

4. The information processing apparatus according to claim 1 , wherein the specific object is a marker having at least one of a specific shape or pattern.

5. The information processing apparatus according to claim 1 , further comprising:
the imaging circuitry configured to:
capture the first image and the second image, and
perform the first focus adjustment and the second focus adjustment.

6. The information processing apparatus according to claim 1 , wherein the circuitry is configured to:
acquire the content corresponding to the specific object when the specific object is detected from the first image,
and
control to not display the content to be superimposed over the second image when the specific object is not detected.

7. The information processing apparatus according to claim 1 , wherein the first focus adjustment and the second focus adjustment are autofocus operations performed by the imaging circuitry.

8. A display control method comprising:
controlling, by a circuitry, imaging circuitry to stop a first focus adjustment when a specific object is detected from a first image captured by the imaging circuitry while the first focus adjustment is in execution, the first focus adjustment being performed at each first time interval by the imaging circuitry,
controlling the imaging circuitry to start a second focus adjustment when the specific object is not detected from a second image captured by the imaging circuitry after the imaging circuitry is controlled to stop the first focus adjustment, and
controlling to display a content to be superimposed over the first image, the content being acquired in accordance with the detected specific object,
wherein the second focus adjustment is performed at each second time interval which is different from the first time interval.

9. The display control method according to claim 8 , wherein the second time interval is shorter than the first time interval.

10. The display control method according to claim 9 , further comprising:
controlling the imaging circuitry to restart the first focus adjustment when the specific object is not detected from a plurality of images which are captured by the imaging circuitry after the imaging circuitry is controlled to start the second focus adjustment.

11. The display control method according to claim 8 , wherein the specific object is a marker having at least one of a specific shape or pattern.

12. The display control method according to claim 8 , further comprising:
acquiring the content corresponding to the specific object when the specific object is detected from the first image,
and
controlling to not display the content to be superimposed over the second image when the specific object is not detected.

13. The display control method according to claim 8 , wherein the first focus adjustment and the second focus adjustment are autofocus operations performed by the imaging circuitry.

14. A non-transitory computer-readable medium including computer program, which when executed by circuitry, causes the circuitry to:
control imaging circuitry to stop a first focus adjustment when a specific object is detected from a first image captured by the imaging circuitry while the first focus adjustment is in execution, the first focus adjustment being performed at each first time interval by the imaging circuitry,
control the imaging circuitry to start a second focus adjustment when the specific object is not detected from a second image captured by the imaging circuitry after the imaging circuitry is controlled to stop the first focus adjustment, and
control to display a content to be superimposed over the first image, the content being acquired in accordance with the detected specific object,
wherein the second focus adjustment is performed at each second time interval which is different from the first time interval.

15. The non-transitory computer-readable medium according to claim 14 , wherein the second time interval is shorter than the first time interval.

16. The non-transitory computer-readable medium according to claim 15 , wherein the program causes the circuitry to:
control the imaging circuitry to restart the first focus adjustment when the specific object is not detected from a plurality of images which are captured by the imaging circuitry after the imaging circuitry is controlled to start the second focus adjustment.

17. The non-transitory computer-readable medium according to claim 14 , wherein the specific object is a marker having at least one of a specific shape or pattern.

18. The non-transitory computer-readable medium according to claim 14 , wherein the program causes the circuitry to:
acquire the content corresponding to the specific object when the specific object is detected from the first image,
and
control to not display the content to be superimposed over the second image when the specific object is not detected.

19. The non-transitory computer-readable medium according to claim 14 , wherein the first focus adjustment and the second focus adjustment are autofocus operations performed by the imaging circuitry.
