  • Publication number: 20090051353
    Abstract: A circular top surface of a magnet is magnetized to the N-pole, and a back surface thereof is magnetized to the S-pole. A detector moves within the X-Y plane at positions located away from the top surface of the magnet. A pair of X-direction detecting elements and a pair of the Y-direction detecting elements are provided in the detector. In the X-direction detecting elements, the directions of a bias magnetic field provided to free magnetic layers are opposite to each other. When the detector moves in the Y direction, a decrease in the sensitivity of one of the X-direction detecting elements is compensated for by an improvement in the sensitivity of the other element. This also applies to the Y-direction detecting elements. Accordingly, position detection outputs of the X direction and the Y direction can be accurately obtained from the detector.

  • Patent number: 7176965
    Abstract: The brightness of image data is previously defined based on the R, G, and B values of each pixel. In an image considered to have been exposed appropriately by a conventional method, when the brightness histogram for the defined image is computed, pixels having the maximum value in the definition of brightness always occupy a predetermined rate (1% or so) of all pixels. Based on this rule of thumb, the gain of an image acquisition device or the pixel value of acquired data is adjusted so that a brightness histogram (3) for image data which is an object of adjustment becomes a histogram (4) having the same characteristic as the above-mentioned appropriately exposed image.

  • Patent number: 7081923
    Abstract: A method for adjusting image brightness is conducted by a system for adjusting image brightness. Digital image data acquired by a data acquisition unit are sent to a lightness computing unit and a color saturation computing unit that compute the lightness L and the color saturation C for every pixel and sends the computed values to a mean value computing unit. The mean value computing unit weights the lightness L by the color saturation C and computes weighted mean values Lm of the lightnesses L. A converter 5 converts the R, G, B color signal components constituting the digital image data S to make the weighted mean values Lm desired values.
