  • Patent number: 10888218
    Abstract: A video laryngeal endoscope system having flat scan video kymography and laryngoscopic functions for analyzing a motion state of a larynx comprises: a laryngoscope for viewing vocal cords; a light source for illuminating the vocal cords; a video camera which has a beam splitter for separating an image viewed by means of the laryngoscope and the light source into two images to acquire a flat scan kymographic image and a stroboscopic image; a dual image capturing unit for converting two image signals transmitted from the video camera into a digital image signal; a storage unit for storing the digital image signal; a control unit for analyzing the digital image signal of the storage unit and simultaneously displaying analysis results of the flat scan kymographic image and the stroboscopic image; and a computer comprising analysis software for analyzing the image signal of the storage unit; and a monitor for displaying photographed images and analysis results.

  • Patent number: 10600168
    Abstract: A method by which a planar scan videokymographic image generation server generates planar scan videokymographic images by using real-time or pre-stored ultra-high speed laryngeal endoscopy images. The method includes the steps of: (a) acquiring monochrome or color ultra-high speed laryngeal endoscopy images; (b) setting a target region and a unit pixel for generating the 2D scan videokymographic images from the ultra-high speed laryngeal endoscopy images; (c) extracting pixel information of each frame of the ultra-high speed laryngeal endoscopy images according to the unit pixel for the target region; (d) generating frames of the planar scan videokymographic images by combining the extracted pixel information of each frame; and (e) generating a planar scan videokymographic video by combining the frames of the planar scan videokymographic images.
