Image pickup apparatus capable of capturing images with proper exposure, control method, and memory medium

A control method of an image pickup apparatus, the control method comprising steps of:

• acquiring an image by using an image sensor;
• and
• reducing image plane blur by moving the image sensor based on a shake amount detected by a shake detection unit;
• wherein the image pickup apparatus has a first mode for acquiring the image based on light passing through an area between an electronic front curtain of the image sensor and a rear blade group of a shutter apparatus, and a second mode for acquiring the image by using a method different from a method used in the first mode,
• wherein in a case where a shutter speed is slower than a predetermined shutter speed, the step of reducing blur executes the control on the image stabilization both in the first mode and the second mode, and
• wherein in a case where the shutter speed is faster than the predetermined shutter speed, the step of reducing blur does not execute the control on the image stabilization in the first mode, and executes the control on the image stabilization in the second mode.

An image pickup apparatus comprising:

• an image sensor configured to acquire an image;
• an image-stabilization mechanism including a fixed portion and a movable portion movable relative to the fixed portion, the movable portion holding the image sensor, the image-stabilization mechanism configured to move the image sensor based on a shake amount detected by a shake detection unit so as to reduce image plane blur caused by a translational movement and image plane blur caused by a rotational movement;
• a shutter apparatus;
• at least one processor;
• and
• at least one memory coupled to the at least one processor storing instructions that, when executed by the at least one processor, cause the at least one processor to function as:
• a control unit configured to provide control on image stabilization by the image-stabilization mechanism,
• wherein the image pickup apparatus has a first mode for acquiring the image based on light passing through an area between an electronic front curtain of the image sensor and a rear blade group of the shutter apparatus, and a second mode for acquiring the image by using a method different from a method used in the first mode,
• wherein in a case where a shutter speed is slower than a predetermined shutter speed, the control unit executes the control on the image stabilization both in the first mode and the second mode, and
• wherein in a case where the shutter speed is faster than the predetermined shutter speed, the control unit does not execute the control on the image stabilization in the first mode so as to reduce a variation in an exposure amount on the image sensor, and executes the control on the image stabilization in the second mode.
