Imaging device with filter switching, method for controlling the same, and storage medium

A method for controlling an imaging device comprising:

• an imaging lens;
• an imaging element;
• an optical element;
• a holder that is arranged between the imaging lens and the imaging element in an optical axis direction of the imaging lens and configured to include an opening on which the optical element is mounted and to hold the optical element;
• a driver that moves the holder in a direction perpendicular to an optical axis of the imaging lens;
• a regulating portion that regulates movement of the holder in the direction perpendicular to the optical axis;
• and
• a detector that detects a position of the holder, the detector includes a light emitter and a light receiver,
• the method comprising:
• determining whether the opening of the holder is within a predetermined range based on a detection result of the detector;
• and
• controlling the driver based on a determination result of the determining,
• wherein the predetermined range is defined by a position where movement of the holder is regulated by the regulating portion and a position where the detection result of the detector is switched, and
• wherein, in a case where the opening of the holder is within the predetermined range, the opening does not block a light beam incident on an effective pixel of the imaging element.

A non-transitory computer-readable storage medium configured to store a computer program for causing an imaging device comprising an imaging lens, an imaging element, an optical element, a holder that is arranged between the imaging lens and the imaging element in an optical axis direction of the imaging lens and configured to include an opening on which the optical element is mounted and to hold the optical element, a driver that moves the holder in a direction perpendicular to an optical axis of the imaging lens, a regulating portion that regulates movement of the holder in the direction perpendicular to the optical axis, and a detector that detects a position of the holder, the detector includes a light emitter and a light receiver, to execute the following steps:

• determining whether the opening of the holder is within a predetermined range based on a detection result of the detector;
• and
• controlling the driver based on a determination result of the determining,
• wherein the predetermined range is defined by a position where movement of the holder is regulated by the regulating portion and a position where the detection result of the detector is switched, and
• wherein, in a case where the opening of the holder is within the predetermined range, the opening does not block a light beam incident on an effective pixel of the imaging element.
