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.
Claims15
An imaging device, comprising:
- 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 configured to drive the blade;
- and
- a blade controller configured to control the blade driver,
- wherein 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, wherein
- the blade controller determines whether the blade is in the closed state at every predetermined time in the non-imaging mode, and when determining that the blade is in the open state, the blade controller controls the blade driver to close the blade.
