Image pickup apparatus and image pickup method

An image pickup apparatus comprising:

• an imaging unit configured to capture a plurality of images while changing a focus position of an optical system during main imaging;
• a setting unit configured to set a plurality of focus positions at which the plurality of images is captured;
• a shake detection unit configured to detect a shake of the imaging unit;
• and
• a combination unit configured to combine at least some of the plurality of images,
• wherein the imaging unit is configured to perform pre-imaging before the main imaging, and
• wherein the setting unit is configured to set the plurality of focus positions based on a shake amount detected by the shake detection unit during the pre-imaging.

An image pickup method comprising:

• capturing by an imaging unit a plurality of images while changing a focus position of an optical system;
• setting a plurality of focus positions at which the plurality of images is captured;
• detecting a shake of the imaging unit;
• and
• combining at least some of the plurality of images,
• wherein, in the setting, distances between the plurality of focus positions are changed based on the detected shake amount and at least some of the plurality of focus positions are set at equal distances based on the shake amount.

An image pickup method comprising:

• performing pre-imaging as first imaging;
• capturing by an imaging unit a plurality of images while changing a focus position of an optical system during main imaging as second imaging after the first imaging;
• setting a plurality of focus positions at which the plurality of images is captured;
• detecting a shake of the imaging unit;
• and
• combining at least some of the plurality of images,
• wherein the plurality of focus positions is set based on a shake amount detected during the first imaging.
