  • Videostroboscopy of vocal cords with CMOS sensors
    Patent number: 10206561
    Abstract: The disclosure relates and extends to a light source having a strobing or pulsing sequence suitable for use with a CMOS sensor that does not require, have, or use a global shutter. Instead, the CMOS sensor synchronizes the strobing input with the blanking portion of the sensor readout pattern and disables the strobing during sensor readout, or when the strobing would otherwise leave artifacts in the image. The CMOS sensor freezes its readout during the strobing.
