Publication number: 20230076396Abstract: A shutter speed determination device includes a motion detector and controller. The motion detector, on a block-by-block basis having a specified block size, performs detection processing of a motion vector for image data obtained by capturing a subject image. The controller, while reducing the block size, causes the motion detector to execute the detection processing repeatedly, each time executing the detection processing the controller finds a motion vector related value that changes in a same direction as a direction in which a magnitude of the motion vector changes, the controller determines a shutter speed used when capturing the subject image thereafter, based on the motion vector related value found.Type: ApplicationFiled: December 25, 2020Publication date: March 9, 2023Inventors: Norikatsu YOSHIDA, Takeshi HAMASAKI

Patent number: 10049699Abstract: A disc tray includes a bottom wall including an outer periphery and an inner rib supporter supporting the lowermost disc from below. The bottom wall is thickened from the outer periphery toward the inner rib supporter. The lowermost disc includes a data recording area, an inner rib, and an outer rib. When the lowermost disc is stationary, the outer rib of the lowermost disc and the upper surface of the bottom wall are separated by a gap. When the lowermost disc is inclined in such a manner that part of the outer rib of the lowermost disc comes into contact with the upper surface of the bottom wall, the data recording area of the lowermost disc and the upper surface of the bottom wall are separated by a gap greater than thickness of the outer or inner rib.Type: GrantFiled: October 25, 2017Date of Patent: August 14, 2018Assignee: Panasonic Intellecutal Property Management Co., Ltd.Inventors: Yoichi Yamamoto, Shinichi Maeda, Norikatsu Yoshida, Shuji Tabuchi
