Patents by Inventor Kenya Fukabori

Kenya Fukabori 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: 11838632
    Abstract: A driving control apparatus is configured to control a driving unit that moves relative to each other a vibrator that is excited to vibrate by applying a first driving signal and a second driving signal that have a phase difference with each other, and a contact member that contacts the vibrator. The driving control apparatus includes a first control unit configured to control the phase difference, and a second control unit configured to control a voltage amplitude of each of the first driving signal and the second driving signal. The second control unit controls the voltage amplitude so that a change rate of the voltage amplitude increases as an absolute value of the phase difference decreases.

  • Patent number: 11445115
    Abstract: An image stabilization apparatus comprising a calculation unit that calculates a driving amount for moving an image sensor so as to compensate for shake, an image stabilization control unit that controls image stabilization by moving the image sensor based on the calculated driving amount, a determination unit that determines whether a current state is a first state according to an image shooting state, and a control unit that controls a shift amount of a center position of image stabilization control so as to be smaller in a case where a center position of the image circle of a lens apparatus is moved from a first position to a second position and the first state is determined than in a case where the center position is moved from the first position to the second position and the first state is not determined.

  • Patent number: 10893188
    Abstract: An imaging apparatus includes an imaging device that photoelectrically converts an optical image obtained through a focus lens. The focus lens is moved to a focus position set by focus detection performed based on image signals from the imaging device with a first aperture value. A first correction amount of the set focus position is acquired according to a difference between the first aperture value and a second aperture value to be used at a time of photographing. Photographing is executed at a determined focus position at the time of photographing, by a user's operation. If the first correction amount is larger than a predetermined amount, a focus position corrected according to the first correction amount is determined as the focus position at the time of photographing, and if not, the set focus position is determined as the focus position at the time of photographing.
