Abstract
An image pickup apparatus includes a gyro sensor 1240 that detects camera shakes, a feed forward value is calculated by multiplying a first coefficient c1 to an output value of the gyro sensor 1240 when the output value of the gyro sensor 1240 is less than a first predetermined value, another feed forward value is calculated by multiplying a second coefficient c2 smaller than the first coefficient c1 to an output value of the gyro sensor 1240 when the output value of the gyro sensor 1240 is greater than or equal to the first predetermined value, each of the products is respectively added by an addition device to an output value of a drive signal.
