Latest Patents

Nagashima holds a patent for a "Real-time endoscopic image processing system." This system is designed to remove net patterns from images captured during endoscopic procedures. The technology includes an image processing section that utilizes a first controlling circuit to receive video signals from various sources, such as television cameras and VTRs. The system employs a horizontal sample-hold circuit to continuously sample and hold the peak value of a sinusoidal video signal, which corresponds to the bright and dark portions of an image. Additionally, a second controlling circuit detects the peak value of the original voltage, which varies in a sinusoidal form, and outputs a vertical peak sampling controlling signal. The processed vertical peak sample-hold signal is then displayed on a monitor, significantly improving the visualization of endoscopic images.
