    摘要: In order to provide a noise removal method for removing noise signals mixed into an image signal without deteriorating picture quality of the overall image, such zigzag noise signals that the difference between the output levels of two pixels adjacent to each other along a noise generation direction alternately takes positive and negative vales at least three times are detected from noise signals mixed into an image signal. Then, a specific pixel is noted among a plurality of pixels corresponding to the noise signals, for calculating a mean value of the output levels of the noise signals with reference to the specific pixel and correcting the output level of a noise signal corresponding to the said specific pixel with the said mean value.

    摘要: A magnetostriction type torque sensor has a magnetostrictive film formed on an outer peripheral surface of a rotary shaft, a coil having a coil centerline extending in a radial direction of the rotary shaft, and a signal processor responsive to coil impedance. Since the coil includes a coil centerline extending in a radial direction of the rotary shaft, magnetic fluxes are formed mainly in a radial direction of the rotary shaft. Accordingly, the magnetic fluxes intruding deep into the rotary shaft are decreased, and the rate of the magnetic fluxes passing through the magnetostrictive film is increased. As a result, the magnetostriction type torque sensor comes to have high sensitivity even when the rotary shaft has high magnetic permeability or high electric conductivity.
