Movement detection apparatus and movement detection method
First Claim
1. An electronic device comprising:
- an acceleration detection unit configured to detect accelerations caused by a shake in at least three-axis directions; and
a control unit configured to execute a predetermined function of said electronic device,wherein the control unit determines 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,the control unit decides a direction of the shake added by the operator based on the result of said determination;
the control unit counts the number of changes in the axis with the minimum value in the acceleration direction, andthe control unit executes the predetermined function of said electronic device in accordance with the number of changes counted.
