Image pickup apparatus, image pickup system, image pickup method, and recording medium

An image pickup system comprising:

• an image pickup apparatus that includes an imaging optical system configured to form an image of an object, an image pickup unit configured to capture the image of the object via the imaging optical system, and a controller configured to control the image pickup unit, the controller setting, so as to always include part of the object in a first image pickup area corresponding to an image pickup plane of the image pickup unit, a second image pickup area by arranging at least one first image pickup area so that the second image pickup area contains an entire object on each of a plurality of sections perpendicular to an optical axis of the imaging optical system, and controls the image pickup unit so as to capture the first image pickup area that contains an in-focus range of the object in the second image area;
• and
• a first measurement unit configured to measure a position of the object in a direction perpendicular to the optical axis direction of the imaging optical system,
• wherein the controller sets the second image pickup area based on a measurement result of the first measurement unit.

• a first measurement unit configured to measure a position of the object in a direction perpendicular to the optical axis direction of the imaging optical system;
• and
• a second measurement unit configured to provides a focus detection for detecting an in-focus position in each first image pickup area set in the second image pickup area, and obtains shape information of the object in the focus detection,
• wherein the controller sets the second image pickup area based on a measurement result of the first measurement unit, and determines whether at least part of the object is imaged on the image pickup plane of the image pickup unit based on a measurement result of the second measurement unit.
