Movement detection apparatus and movement detection method
First Claim
1. A movement detection apparatus that detects a shake added by an operator to execute a function of a device, said apparatus comprising:
- an acceleration detection unit configured to detect accelerations caused by a shake in at least three-axis directions;
a determination unit configured to determine an axis with a minimum value of acceleration and an axis with a maximum value of acceleration among the accelerations in at least three-axis directions detected by said acceleration detection unit;
a decision unit configured to decide a direction of the shake added by the operator based on the axis with the minimum value and the axis with the maximum value determined by said determination unit; and
a selection unit configured to select a predetermined function based on the result of said decision unit.

9. A movement detection method of detecting a shake added by an operator to execute a function of a device, said method comprising:
-
an acceleration detection step of detecting accelerations caused by a shake in at least three-axis directions; a determination step of determining an axis with a minimum value of acceleration and an axis with a maximum value of acceleration among the accelerations in at least three-axis directions detected in said acceleration detection step; a decision step of deciding a direction of the shake added by the operator based on the axis with the minimum value and the axis with the maximum value determined in said determination step; and a selection step of selecting a predetermined function based on the result in said decision step. - View Dependent Claims (10)
