  • Patent number: 10999500
    Abstract: There is provided an imaging apparatus and an imaging method, and an image processing apparatus and an image processing method each capable of capturing a high resolution image by effectively using respective pixel signals of a plurality of pixels defined by pupil division immediately below a microlens. A disparity is detected in units of pupil on the basis of respective pixel values of a plurality of divided pixels defined by pupil division. The pixel values of the plurality of divided pixels are added in units of pupil to obtain an added pixel value. The pixel value of the divided pixel and the added pixel value are blended in units of divided pixel in accordance with the disparity. The present disclosure is applicable to an imaging apparatus.

  • Patent number: 10999562
    Abstract: On the basis of a first imaging signal corresponding to a first viewpoint and including white pixels and color component pixels and a second imaging signal corresponding to a second viewpoint different from the first viewpoint and including fewer white pixels than the first imaging signal to increase a rate of the color component pixels in the second imaging signal, a parallax detecting section detects a parallax of the second viewpoint with respect to the first viewpoint. A parallax compensating section performs parallax compensation for the imaging signal for the second viewpoint on the basis of the detected parallax to generate a parallax-compensated color difference signal for the first viewpoint. A fallback determining section and a signal selecting section selects a parallax-compensated second color difference signal or a color difference signal for the first viewpoint to obtain a high-sensitivity captured image while suppressing degradation of the image quality performance.

  • Patent number: 7104908
    Abstract: A rear bicycle derailleur includes a base member, a movable member, a guide arm and a tension arm. The base member is adapted to be mounted to a bicycle frame. The movable member is movably coupled to the base member, preferably via a linkage, to move between a retracted position and an extended position. The guide arm is pivotally coupled to the movable member around a first axis and has a guide sprocket. The tension arm is pivotally coupled to the movable member around a second axis and has a tension sprocket. Preferably, the guide arm is freely pivotal about the first axis without being rotationally biased, while the tension arm is rotationally biased by a biasing member about the second axis. Preferably, the guide arm and the tension arm are configured and arranged to move independently of each other.

  • Publication number: 20040106482
    Abstract: It is the problem to provide a rear derailleur having structure in which even when the chain has been looped over a chain wheel of major diameter, the tension sprocket wheel does not come so closer to the ground to thereby reduce accidents of a violent fall or trouble. Further, it is the problem to facilitate detachment and attachment of the wheel, and to provide a rear derailleur having a wide application range to wheel size. To solve these problems, the guide arm and the tension arm are capable of rocking around the guide arm rocking axis and the tension arm rocking axis which are different from each other, and these arms are rocked independently of each other, and the distance between the guide sprocket wheel and the tension sprocket wheel varies with the speed variation state.

  • Patent number: 6089122
    Abstract: A connecting structure between a bicycle pedal and a cleat, comprising hooks pivotably supported by a pedal body for engaging and releasing the cleat, and an urging device for urging the hooks toward engaging positions. The object is to allow the cleat to be released with increased reliability when, for example, the cyclist falls over with his shoe becoming obliquely inclined relative to the pedal. A first cam mechanism is provided between each of the hooks and the cleat for causing the hook to pivot in a releasing direction when the cleat is inclined about a first imaginary axis extending substantially along a direction of pivotal movement of the hooks. The first cam mechanism includes a first pressed edge defined on one of the hooks and opposed to the cleat, and a first pressing edge defined on the cleat and opposed to one of the hooks for slidable contact with the first pressed edge.

  • Patent number: 5979266
    Abstract: A brake control apparatus for a bicycle. The appratus has a control lever operatively connected with a control cable for pulling the cable and a force transmission ratio adjuster mechanism for adjusting a force transmission ratio in association with an operation of the control lever. The force transmission ratio is defined as a ratio obtained by dividing an output force from the cable associated with application of a unit input force to a certain lever position of the control lever. With the appratus of the invention, this force transmission ratio is so determined as to have a maximum value at a position during an entire stroke of the lever between a stroke start end and a stroke finish end and the maximum value position is on the side of the finish end after a play stroke on the side of the start end.

  • Patent number: 5557985
    Abstract: An apparatus for coupling a cleat has a pedal shaft for rotatably supporting a pedal, a tread surface extending parallel to the pedal shaft for contacting a bottom of a shoe, a first pivotal axis provided on the pedal, and a first cleat clamp pivotable about the first pivotal axis. The first cleat clamp includes a recess for engaging one end of the cleat until a force exceeding a predetermined value is applied thereto. Further, this apparatus has a second cleat clamp opposed to the first cleat clamp across the pedal shaft, and a pair of restrictor projections disposed between the second cleat clamp and the pedal shaft for restricting displacement to the cleat. The second cleat clamp cooperates with the first cleat clamp to couple the cleat to the pedal. The restrictor projections are spaced apart from each other by a distance greater than a width along the pedal shaft of a portion of the cleat for contacting the restrictor projections.

  • Patent number: 5537891
    Abstract: A bicycle brake lever mechanism having a bracket mountable to a bicycle handlebar, a lever mounted for pivotal movement to the bracket and a brake cable connector connected to the lever. The cable connector is connected to the lever via an adjusting mechanism for so that the return position of the brake lever relative to a lever bracket may be adjusted to accommodate various sized hands. Further, the adjusting mechanism allows for adjustment of a lever ratio A which is defined mathematically by the distance between the pivot point of the lever and the pivot point of the cable connector on the lever divided by the distance from a set point on the brake lever to the pivot point of the lever.
