Classification: CPC H  G | IPC G  H

Claim 0:
1. An imaging device, comprising:
an imaging unit configured to receive subject light through an opening in a housing and generate image data;
a recording controller configured to record the image data generated by the imaging unit onto a recording medium;
a light shield movable to a position at which the light shield covers the opening to restrict the subject light from entering the imaging unit;
a determiner configured to detect a position of the light shield based on the image data generated by the imaging unit and determine whether the light shield covers the opening,
wherein the recording controller stops recording the image data onto the recording medium when the determiner determines that the light shield covers the opening; and
an imaging controller configured to reduce an amplification factor of a signal for the imaging unit to generate the image data to a predetermined amplification factor after the light shield changes from a state in which the light shield covers the opening to restrict the subject light from entering the imaging unit to a state in which the light shield releases restriction of entry of the subject light into the imaging unit.
