摘要： Two-phase resolver signals output from a rotation angle detector are squared by first and second squaring circuits. The squared signals are added by an adding circuit. The DC component of the output signal from the adding circuit is removed by a filter. The output signal from the filter is compared with a reference potential by a comparator to generate a rectangular-wave signal. The phase of the rectangular-wave signal is corrected a phase shifter. The frequency of the output signal from the phase shifter is divided by 2 by a frequency dividing circuit in synchronization with an excitation signal supplied to the rotation angle detector to generate a synchronous clock.

摘要： In an image resolution conversion apparatus, a region-determining section establishes an initial value used for determining a region where a new pixel is to be generated based on the number of pixels in a non-line direction included in a pixel group used for converting the resolution attribute of fields, and a resolution conversion magnification ratio. The region-determining section accumulates an integration parameter corresponding to the resolution conversion magnification ratio onto the obtained initial values under the predetermined condition.
