Imaging apparatus and control method thereof of with determining of driving range in which panning driver or tilting driver rotates imaging unit

An imaging apparatus comprising:

• at least one processor and at least one memory, functioning as:
• (1) a first correcting unit configured to correct image blur by driving at least one of (a) a panning driver that rotates an imaging unit including an imaging optical system and an image sensor in the horizontal direction and (b) a tilting driver that rotates the imaging unit in the vertical direction;
• (2) a shake detection unit configured to detect shake;
• (3) a calculation unit configured to calculate an amount of image blur correction in accordance with the shake detected by the shake detection unit;
• and
• (4) a determination unit configured to determine a pan driving range or a tilt driving range in which the panning driver or the tilting driver rotates the imaging unit for changing an imaging direction according to a pan drive instruction or a tilt drive instruction, wherein the pan driving range or the tilt driving range is determined in accordance with (a) the amount of image blur correction and (b) a mechanical driving end of the panning driver or the tilting driver so that the image blur correction can be performed without reaching the mechanical driving end of the panning driver or the tilting driver even if the imaging unit is rotated according to the pan drive instruction or the tilt drive instruction,
• wherein the determination unit makes the pan driving range or the tilt driving range narrower than a mechanical drivable range of the panning driver or the tilting driver in accordance with the amount of image blur correction, and
• wherein a range between the mechanical driving end and the pan driving range or the tilt driving range is used for correcting the image blur by the first correcting unit but is not used for changing the imaging direction according to the pan drive instruction or the tilt drive instruction.
