Title: Electronic endoscope for recording still image
Inventor: IRIYAMA KENICHI
IPC: G02B23/24
Filed: 2002-09-12
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a properly bright still image without repeating a freezing operation.  <P>SOLUTION: A videoscope 50 having a CCD 54 is connected to a processor 10. Then, an image signal read from the CCD 54 is processed and a moving picture is displayed on a monitor 60. A liquid crystal shutter 35 is operated by depressing a freeze switch button 58 arranged in the videoscope 50. In this case, the molecular arrangement of the liquid crystal shutter 35 is changed to allow a light quantity toward a subject S to reach a reference light quantity. When the light quantity reaches the reference light quantity, an electronic shutter is operated. Then the still image is recorded in an image recording memory 75 and a video-recorder 70.  <P>COPYRIGHT: (C)2004,JPO

Title: Method and apparatus for performing nyquist folding frequency modulation
Inventor: MCNEELEY DAVID LOWELL
IPC: H03D7/16
Filed: 2002-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a digital process for remodulating an RF carrier modulated signal (RFcms). SOLUTION: A method and apparatus for re-modulating an RF carrier modulated signal using a Nyquist folding frequency modulation technique. The method modulates a digitized RF carrier modulated signal with a digital sequence of (1, -1, 1, -1, etc.), where the center frequency of the RF carrier modulated signal is at a first frequency and the sample rate of the modulating signal is at a second frequency. When the second frequency is four times the first frequency, the output of the digital modulation process is a spectrum-inverted copy of the source RF carrier modulated signal. For all other frequencies, the remodulated RF carrier modulated signal has a center frequency equal to the carrier frequency minus one-half the sample rate of the modulating signal.  A spectrum inversion is then performed to recreate the spectrum of the source RF carrier modulated signal, which is now located at a different center frequency. The apparatus comprises a modulating signal source and a digital modulator. A resampler and a spectrum inverter may be used as needed.
