<p>PROBLEM TO BE SOLVED: To accurately decide a supporting state regardless of an individual difference in operating an operation unit by calculating a threshold level through calibration operation. SOLUTION: A data address is set so that various flags, coefficients, and calculated results and the like can be read and written as pitch data if a control direction is decided to be pitch direction of a pitch direction or a yaw direction. Output from an angular velocity sensor being one example of a shake sensor 106 is A/D converted and the converted result is stored in the previously defined AD-DATA of a RAM. Whether or not a mode has been set to a calibration mode for performing the calibration operation to calculate and set the threshold level in arithmetic operation to decide a supporting state is decided. If it is decided that the calibration mode has been set, the calibration operation to calculate and set the threshold level in the arithmetic operation to decide the supporting state is performed. Then, high-pass filter(HPF) arithmetic operation and integral arithmetic operation are initialized.</p> |
