Abstract

An information processing apparatus capable of preventing unintentional vibration from being erroneously recognized as vibration caused by a tapping operation is provided. The information processing apparatus detects acceleration caused by vibration applied thereto, determines whether the amplitude of acceleration data detected by the acceleration sensor is greater than or equal to a threshold, analyzes a frequency of the acceleration data when the amplitude is greater than or equal to the threshold, and executes processing assigned to the tapping operation when the frequency analysis result indicates the tapping operation.

Claims

1. An information processing apparatus in which a specific process is associated to a specific vibration applied to a housing of the information processing apparatus, the information processing apparatus comprising:

an acceleration sensor configured to detect acceleration caused by vibration and provide acceleration data which represents the vibration; and

a control unit configured to execute the specific processing corresponding to the specific vibration when acceleration data provided by the acceleration sensor does not satisfy a specific condition and the acceleration sensor provides acceleration data showing the specific vibration, and not execute the specific processing corresponding to the specific vibration when the acceleration data provided by the acceleration sensor satisfies the specific condition and the acceleration sensor provides the acceleration data showing the specific vibration.

2. The information processing apparatus according to claim 1, wherein the specific condition is that the acceleration data shows other vibration, which is not the specific vibration, immediately before the acceleration sensor detects the acceleration having the specific vibration.

3. The information processing apparatus according to claim 1, wherein the specific condition is that the acceleration data shows vibration that does not correspond to the specific processing immediately before the acceleration sensor detects the acceleration having the specific vibration.

4. The information processing apparatus according to claim 1, wherein the specific condition is that the acceleration data showing the specific vibration is determined to indicate vibration caused by an impact shock applied from a side of the information processing apparatus opposite to a gravitational direction, and it is determined that the information processing apparatus stands still for a subsequent predetermined time.

5. The information processing apparatus according to claim 1, wherein the specific condition is that the acceleration data showing the specific vibration is determined to indicate vibration caused by an impact shock applied from a side of the information processing apparatus opposite to a gravitational direction.

6. The information processing apparatus according to claim 1, wherein the specific condition is that acceleration data indicating drop is provided by the acceleration sensor.

7. The information processing apparatus according to claim 1, wherein the information processing apparatus is a portable information processing apparatus.

8. The information processing apparatus according to claim 1, wherein the information processing apparatus is an imaging apparatus including an imaging unit.

9. A method for controlling an information processing apparatus configured to detect vibration applied to a housing thereof using an acceleration sensor, and to execute a specific process for a specific vibration, the method using an acceleration sensor configured to detect acceleration caused by vibration and provide acceleration data which represents the vibration, the method comprising:

determining whether the acceleration data provided by the acceleration sensor satisfies a specific condition; and

executing the specific processing corresponding to the specific vibration when acceleration data provided by the acceleration sensor does not satisfy the specific condition and the acceleration sensor provides acceleration data showing the specific vibration, and not executing the specific processing corresponding to the specific vibration when the acceleration data provided by the acceleration sensor satisfies the specific condition and the acceleration sensor provides the acceleration data showing the specific vibration.

10. A non-transitory computer-readable storage medium configured to store a program causing a computer to execute the method of claim 9.
