<P>PROBLEM TO BE SOLVED: To provide an image device capable of determining whether acceleration generated in the image device depends on gravity or an external force except the gravity and determining the posture of the image device correctly. <P>SOLUTION: The image device is provided with a fluctuation detecting means 48 for detecting the fluctuation and outputting fluctuation information, an objective position calculating means for moving a correcting means 14 according to the fluctuation information, a position detecting means 122 for detecting the present position of the correcting means, a deflection calculating means 120 to calculate deflection between the present position and a target position and posture determining means 110, 112, 114 each determining an action applied on the image device as gravity when the vibration information is not larger than a specified value or when a period is not longer than a specified period of time even if the vibration information is not smaller than a specification while determining the action applied on the image device as an external force except the gravity and determines the posture based on the determination when the vibration information is not smaller than the specified value and its period of time is not shorter than the specified period of time. <P>COPYRIGHT: (C)2009,JPO&INPIT |
