IMAGE SHAKE CORRECTING DEVICE AND CONTROL METHOD THEREFOR, OPTICAL APPARATUS, AND IMAGE PICKUP APPARATUS

This image pickup apparatus performs feedback control so that a position of a shake correcting lens converges to a target position. A LPF and a subtracting unit divide a shake signal into low-frequency and high-frequency components. An adding unit combines each output of a high-frequency LPF and a low-frequency LPF and output the target position. A pan/tilt determination unit determines a panning speed from the shake signal. If the panning is fast, the target positions of the low-frequency and the high-frequency are controlled to converge to 0, and calculation for the target position of the high-frequency starts before that of the low-frequency at the end determination. If the panning is slow, only the target position of the low-frequency is controlled to converge to 0. The pan/tilt determination unit changes a determination condition for the detection depending on whether it is at the handheld photographing or the static state.
