Abstract
A movement detection apparatus that detects a shake added by an operator to execute a function of a device, the apparatus comprises 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 the 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 the determination unit; and a selection unit configured to select a predetermined function based on the result of the decision unit.
Claims7
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, and
- the control unit executes the predetermined function of said electronic device in accordance with the number of changes counted.
An image capturing apparatus comprising:
- an acceleration detection unit configured to detect accelerations caused by a shake in at least three-axis directions;
- a control unit configured to execute a predetermined function of said electronic device;
- a display unit configured to display an image;
- and
- 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;
- the control unit executes one of a slide show of an image displayed on said display unit and a rotation of an image in accordance with the number of changes counted.
A method of controlling an electronic device, the method comprising:
- detecting accelerations caused by a shake in at least three-axis directions;
- determining an axis with a minimum value of acceleration and an axis with a maximum value of acceleration among the detected accelerations in at least three-axis directions;
- deciding a direction of the shake added by the operator based on the determination result;
- counting the number of changes in the axis with the minimum value in the acceleration direction;
- and
- executing a predetermined function of said electronic device in accordance with the counted number of changes.
