  • Patent number: 9955078
    Abstract: An image shake correction device provided in an image pickup apparatus drives an image shake correction lens on the basis of detection information about shaking and corrects the image shake. An angular velocity sensor detects an angular velocity of shaking, and a motion vector detection unit detects a motion vector from a plurality of images that has been captured. An adaptive digital filter and an adaptive algorithm unit perform a process that generates a compensation value for a shake correction remainder, and FF (feed forward) control is performed in accordance with the result of the process. In the FF control, a filter coefficient of the adaptive digital filter is adjusted on the basis of the motion vector and a detection signal for shaking. The control filter calculates a feedback control amount so as to track the position of the image shake correction lens to a target position.

  • Patent number: 9873619
    Abstract: According to one embodiment, an apparatus for measuring hydroxyl radicals that measures hydroxyl radicals produced by irradiating a liquid to be treated flowing through a channel in which an ultraviolet lamp is arranged with ultraviolet rays, the apparatus includes a diverting unit, a reagent adding unit, and a measuring unit. The diverting unit has a diverting channel that diverts the liquid to be treated before being irradiated with the ultraviolet rays from the channel and part of which is arranged at a position enabling the liquid to be treated within the channel to be irradiated with the ultraviolet rays. The reagent adding unit adds a hydroxyl radical measuring reagent to the diverted liquid to be treated. The measuring unit irradiates the diverted liquid to be treated with the ultraviolet rays and measures the amount of hydroxyl radicals produced based on a change in the hydroxyl radical measuring reagent between before and after the irradiation with the ultraviolet rays.

  • Patent number: 9749533
    Abstract: This image pickup apparatus performs feedback control so that a position of a shake correcting lens converges to a target position. A LPF and a subtracting unit divide a shake signal into low-frequency and high-frequency components. An adding unit combines each output of a high-frequency LPF and a low-frequency LPF and output the target position. A pan/tilt determination unit determines a panning speed from the shake signal. If the panning is fast, the target positions of the low-frequency and the high-frequency are controlled to converge to 0, and calculation for the target position of the high-frequency starts before that of the low-frequency at the end determination. If the panning is slow, only the target position of the low-frequency is controlled to converge to 0. The pan/tilt determination unit changes a determination condition for the detection depending on whether it is at the handheld photographing or the static state.

  • Patent number: 9661224
    Abstract: This image pickup apparatus detects a shake and performs feedback control. A LPF and a subtracting unit divide a detection signal into low-frequency components and high-frequency components. An output of the LPF for integrating the high-frequency components and the LPF for integrating the low-frequency components are combined in an adding unit to output the result as the target position of the correcting lens. A HPF removes the low-pass components of the shake amount applied to the image pickup apparatus. A control switching determination unit switches a first control mode for performing an image shake correction by a signal produced by frequency dividing a signal after processing signal with the HPF, and a second control mode for performing the image shake correction by a signal that is generated by subtracting a fixed offset amount calculated with the HPF based on the shake signal and dividing the result into the frequency components.
