Imaging device and electronic device

Abstract

An imaging device includes an image sensor, a blade operable to switch between a closed state to at least partially block light incident on the image sensor and an open state to allow light to be incident on the image sensor, a blade driver that drives the blade, a blade controller that controls the blade driver, an authentication processor that performs authentication based on a result of imaging performed by the image sensor, and an operation detector that detects an operation. The blade controller controls the blade driver to place the blade in the open state in response to a predetermined operation detected by the operation detector and to place the blade in the closed state in response to a predetermined time passing in the open state of the blade and no success in the authentication performed by the authentication processor.

Dependencies are inferred from the claim text.
