  • Driving apparatus, optical apparatus, system, image pickup apparatus, and lens apparatus
    Patent number: 11435549
    Abstract: A driving apparatus performs driving of an object. The apparatus includes a driving device for the driving; a position detector, and a controller. The position detector is configured to detect the position of the object. The controller is configured to generate a first signal for open-loop control of the driving device based on a target velocity of the object, generate a second signal for closed-loop control of the driving device based on the detected position and a target position of the object, and generate a driving signal for the driving device based on at least one of the first signal and the second signal. The controller is further configured to perform weighted summing of the first signal and the second signal to generate the driving signal based on inversion between positive and negative of load for the driving device.

  • Image display apparatus and image display method
    Patent number: 10805590
    Abstract: An image display apparatus is worn by a user in such a manner that a first image and a second image are displayed on display units corresponding to both of the user's eyes, wherein, at corresponding positions in the first and the second images, the display units display test patterns including the same graphics that enable the user to adjust the wearing position of the image display apparatus.
