  • Publication number: 20100310245
    Abstract: A lens position calculator is provided that determines a phase of a driving signal as a reference position of an imaging lens when an output value of a position detection sensor reaches a threshold value. The lens position calculator determines a position obtained by performing addition or subtraction on the reference position read out from a reference position storage as a judgment position, detects an output value of the position detection sensor at a timing in synchronization with the driving signal that drives a driver and at the judgment position, and judges whether the output value of the position detection sensor at the judgment position reaches the threshold value or not, so as to determine the reference position again.

  • Publication number: 20090167878
    Abstract: An image pickup apparatus of the present invention is an image pickup apparatus including an ultrasonic motor 35 that moves a focus lens 24, and further including a correction control part 100 that operates the ultrasonic motor 35 under a predetermined condition. The correction control part 100 is capable of executing a correction process by measuring a frequency characteristic of an applied voltage at the time of operating the ultrasonic motor 35 at a predetermined rotation speed, comparing the frequency characteristic with a preset reference frequency characteristic, and correcting the frequency characteristics on the basis of a difference between the frequency characteristic and the reference frequency characteristic so as to calculate a correction frequency characteristic. Accordingly, even when the frequency characteristic of the ultrasonic motor varies due to wear of the ultrasonic motor and mechanical components coupled thereto, a stable drive can be maintained over a long time.

  • Patent number: 7400825
    Abstract: An imaging apparatus measures shake of the apparatus using a gyro sensor, performs “a center stop control” until receiving an instruction to start recording the still picture, and performs “a lens correction control” after the start of exposure in the imaging apparatus. The center stop control controls the correction lens position to stop a correction lens at an optical axis center position (position of the correction lens at which an optical axis of the imaging lenses coincides with an optical axis of a correction lens). The lens correction control controls the correction lens position to correct blurring of the image formed on an imaging element based on the measuring result. The imaging apparatus returns the correction lens to the optical axis center position before receiving a next instruction to start a next recording, and then performs the center stop control on the correction lens.

  • Publication number: 20050124034
    Abstract: A method for producing gelatin peptide comprises the steps of cleaning fish skin with 0.1-5% salt water and fresh water, obtaining an extract from the fish skin using fresh water in neutral pH at 50-100° C., subjecting the water phase to enzymatic digestion, concentrating solution of the digest, activated carbon treatment of the concentrated solution of the digest, and drying the yield. The concentration of salt in the salt water used as cleaning water is preferably 0.5-2%. The fish skin is preferably from white meat fish. The fish skin from pollack such as Alaskan pollack or Pacific cod is particularly preferred. This method enables one to obtain, from fish skin, gelatin peptide from which fish odor is sufficiently eliminated by utilizing simplified processes to be executed under easily adjustable conditions.
