A system, method, scope device, and camera control module device for a video endoscopy system, to enable scopes to operate with a rolling shutter-type image sensor. With selected pulsing of a strobe light, subset image data from adjacent rolling-shutter frames is selected, gain compensated for missing light and combined into a new single video frame.

A video laryngoscope system includes an imager, an audio processing circuitry, a light source, an exposure controller, and a line gain module. The imager generates a first frame and a second frame of a plurality of video frames using a rolling shutter. The audio processing circuitry determines a base frequency of a vocalization based on an audio signal. The light source generates pulses of light based on the base frequency. The exposure controller adjusts a duration and position in time of the pulses based on the base frequency during the first and second frames. The line gain module selectively applies a line gain to at least a portion of the first frame and a portion of the second frame based on a gap time between the first frame and the second frame and the duration and position in time of the pulses.

A system, method, scope device, and camera control module device for a stroboscopic laryngoscope, to enable scopes able to operate with a rolling shutter-type image sensor. With selected pulsing of a strobe light, subset image data from adjacent rolling-shutter frames is selected, gain compensated for missing light and combined into a new single video frame.

A frequency-domain sample interval corresponding to a time-domain pitch period L corresponding to a time-domain pitch period code of an audio signal in a given time period is obtained as a converted interval T.sub.1, a frequency-domain pitch period T is chosen from among candidates including the converted interval T.sub.1 and integer multiples UT.sub.1 of the converted interval T.sub.1, and a frequency-domain pitch period code indicating how many times the frequency-domain pitch period T is greater than the converted interval T.sub.1 is obtained. The frequency-domain pitch period code is output so that a decoding side can identify the frequency-domain pitch period T.
