  • Publication number: 20210280618
    Abstract: An image pickup apparatus that enables to quickly capture an image from which a predetermined reflected light component is removed with desired sensitivity. A polarizing filter two-dimensionally arranges a plurality of sets each of which includes polarizing filter elements having different polarization directions. A first image sensor has pixels that respectively correspond to polarizing filter elements of the polarizing filter. A polarization calculation unit detects a polarized component of light that enters into a region in which one set of polarizing filter elements are arranged based on signals output from pixels in the region of the first image sensor for each region. A correction unit corrects a pixel signal output from a pixel of a second image sensor corresponding to the region based on a calculation result by the polarization calculation unit for each pixel of the second image sensor.

  • Publication number: 20210266444
    Abstract: An image capturing apparatus that has an image capturing device including polarization elements and sets a proper frame rate according to a situation when acquiring a video using polarization information. The image capturing device an image capturing device including polarization pixels that detect polarization information of a plurality of different directions. The polarization information of the polarization pixels is determined by performing first polarization calculation or second polarization calculation which is smaller in calculation load than the first polarization calculation, on video signals output from the polarization pixels. A polarization-processed image is generated by using the polarization information. The first polarization calculation and the second polarization calculation are switched according to a predetermined timing, a mode, or a result of detecting a predetermined state.

  • Patent number: 11090756
    Abstract: An aluminum plate (103) is overlaid on a steel plate (102). A distal end (113) of a button component (101) is pushed in from the obverse surface side of the aluminum plate (103), and the distal end (113) is abutted against the steel plate (102) by applying a first pressure to the button component (101) made of steel without heating. The distal end (113) of the button component (101) and the steel plate (102) are welded by resistance spot welding while applying a second pressure lower than the first pressure to the button component (101).

  • Patent number: 7571939
    Abstract: A pipe joint includes a socket, a plug, a retaining unit for preventing the plug from being drawn out from the socket, a seal ring arranged at an inner periphery of the socket and a hold ring arranged at the inner periphery of the socket for preventing the seal ring from being moved. A projected portion is formed at a position of the inner periphery of the socket for attaching the hold ring, and the hold ring includes a notched portion or a recess portion for engaging with the projected portion, and a projected portion projected in a direction of an inserting port of the plug, and the plug includes a ring-like projected portion for engaging with the retaining unit, and a recess portion or a flat portion provided at the ring-like projected portion to engage with the projected portion of the hold ring.
