When the camera is performing the pan or tilt operation on performing
image blurring correction, the image blurring correction is stopped and a
vibration-proof lens is returned to a reference position at a speed that
is changed according to a focal length of the zoom lens and is reduced if
the zoom lens is set on a wide-side in particular so as to prevent a
sense of discomfort due to swingback on the pan or tilt operation. The
vibration-proof lens may be kept at a fixed position for a fixed time and
returned to the reference position after the fixed time elapses so as to
alleviate disorder of an image. The control subject for correcting the
image blurring may be returned to the reference position by a
predetermined function of which variable is time so as to exert control
after stopping the image blurring correction on the pan or tilt operation
suitably as intended.
