Daisuke KAKEMIZU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11979653
    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.
    Type: Grant

  • Patent number: 11143935
    Abstract: A technique prevents leakage of private images and/or images unintended by a user from an imaging device connected to a network, without a troublesome manual operation of opening and closing a cover. A blade operating device includes a blade that opens and closes an optical path of an imaging device connectable to a network, a blade driver that opens and closes the blade, and a controller that controls the blade driver. The controller controls the blade driver to close the blade when the imaging device is turned off.

  • Patent number: 11082594
    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.

  • Patent number: 10942421
    Abstract: A blade driving device includes a blade for covering an opening for an imaging device operable through motor driving and a user manual operation. A blade driving device includes a base with an opening for an imaging device, a movable member movable relative to the base in X-direction and including a slider held on the base and movable in X-direction, a blade connected to the slider, and a knob on a side of the base opposite to the slider and operable to move the blade, a motor that moves the movable member in X-direction until the blade covers or uncovers the opening in the base, and a lead screw and a driving member that transmit rotation of the motor to the slider in the movable member to move the movable member.
