  • Patent number: 7538806
    Abstract: From horizontal and vertical coordinate values HC and VC of a pixel, a distance operation unit calculates a distance value RV indicating the distance from an optical-axis position to the pixel. A correction-data operation unit receives the distance value RV, and calculates correction data CD for the pixel by referring to an approximation function indicating relation between distance values and correction data. The approximation function is divided into a plurality of segments, and in each segment represented by a quadratic function defined by a predetermined number of sample points.

  • Patent number: 7457486
    Abstract: A solid-state imaging element includes photoelectric conversion elements having a complementary or Bayer color filter array. The solid-state imaging element adds together electric charges stored in nine photoelectric conversion elements having color filters of one of multiple colors in each portion of six rows and six columns, to obtain a resulting electric charge, and outputs the resulting electric charge as one pixel. A portion for one of the colors deviates from a portion for each of the other colors by three rows and/or three columns. This pixel-addition operation produces an effect of a spatial low pass filter, thereby reducing signal components exceeding a Nyquist frequency corresponding to a target resolution. Consequently, aliasing noise in an image with the target resolution is reduced, and therefore higher image quality can be achieved, when compared with a conventional resolution reduction technique.

  • Patent number: 7351047
    Abstract: The present invention provides an improved swash plate type variable capacity fluid machine which is fluid-tight, simple in structure, quiet in operation, and highly durable, yet without increasing its size, weight, and the amount of power loss. The swash plate type variable capacity fluid machine includes: a cone; a disk; an enclosure wall whose inner shpherical surface surrounds the outer circumference of the disk; and a partition plate movably fitted in a groove of the cone. The cone and the disk are arranged to confront each other on an abutment line, thereby defining a plurality of variable capacity compartments. Supplying/discharging holes are provided to communicate with the variable capacity compartments, supplying and discharging a fluid there from. A synchronous mechanism causes the cone and the disk to rotate about their center axis in synchronization.
