Abstract
An imaging device used in, for example, a smartphone controls a blade to avoid remaining open after unauthorized external access or a drop impact. The imaging device includes an image sensor, a blade operable to switch between a closed state in which the blade at least partially blocks light incident on the image sensor and an open state in which light is incident on the image sensor, a blade driver that drives the blade, and a blade controller that controls the blade driver. The blade controller determines whether the blade is in the closed state in a non-imaging mode in which imaging is off, and when determining that the blade is in the open state, the blade controller controls the blade driver to close the blade.
