Shutter apparatus, imaging apparatus, control method of shutter apparatus, and storage medium

An imaging apparatus comprising:

• a shutter apparatus;
• and
• an image sensor configured to photoelectrically convert an optical image formed through an imaging optical system,
• wherein the shutter apparatus includes:
• a shutter base plate having an opening;
• a light shielding member movable to provide a closed state for closing the opening and an open state for opening the opening;
• and
• at least one processor or circuit configured to perform operations of a control unit configured to control the light shielding member configured to reciprocate relative to the opening so as to move the light shielding member in a first direction for a forward exposure and in a second direction opposite to the first direction for a return exposure,
• wherein the control unit varies an exposure correction amount of the light shielding member between the forward exposure and the return exposure.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method of a shutter apparatus control method so as to move a light shielding member in a first direction for a forward exposure, and in a second direction opposite to the first direction for a return exposure,

• wherein the control method includes the steps of:
• moving the light shielding member by a first exposure correction amount during the forward exposure;
• and
• moving the light shielding member by a second exposure correction amount different from the first exposure correction amount during the return exposure.
