    摘要: A pattern analyzing portion analyzes a pattern of a detected repeat field and determines whether or not the pattern of the repeat field is continuous. An inverse pull-down controlling portion controls a memory to read video data in such a manner that the repeat field detected by a comparator is removed from input video data in a period that the pattern of the repeat field is continuous. The inverse pull-down controlling portion controls the memory to read video data in such a manner that a repeat field detected by the comparator is not removed from the input video data in a period that the pattern of the repeat field is discontinuous. In other words, an inverse 2:3 pull-down process is controlled corresponding to the continuity of a pattern of a repeat field. In addition, it is determined whether an input original material is a progressive-scanned video material or an interlace-scanned video material corresponding to the continuity of the pattern of the repetitive material.

In this ultrasonic diagnostic apparatus, a plurality of transducer elements are arrayed and used as an ultrasonic probe, and the transducer elements are driven by a plurality of transmission driving circuit. The signal received by the transducer element is distributed to any of a plurality of input terminals of a cross point switch beam former. The received signals of the three transducer elements near the center of the aperture of the ultrasonic probe are added and inputted to one terminal of a beam former. The second, fourth and sixth transducer elements at the end of the aperture are not connected to the beam former. The signals received by the transducer elements are delay-added by the beam former. The delay precision can be improved, and the beam shape can be made sharper, thereby improving the image quality of the ultrasonic image.

    摘要: A filter processing system making it possible to be able to set a frequency pass-band automatically and to provide the optimum filter to an input signal. A filter processing method of an output signal of an Optical Time Domain Reflectometer (OTDR) in a chromatic dispersion distribution measuring apparatus is disclosed. The filter processing method includes establishing measuring-condition parameters, generating an ideal signal waveform based on previously established chromatic dispersion values and the measuring-condition parameters, and providing correlation results between the ideal signal waveform and a filter input signal. The method also includes comparing the correlation results to a threshold value to generate a minimum chromatic dispersion value and a maximum chromatic dispersion value, and performing filter processing for the output of the OTDR based on the minimum chromatic dispersion value and the maximum chromatic dispersion value.
