Introduction

Qin Zhang is a notable inventor based in Vancouver, Canada. He has made significant contributions to the field of video signal processing, holding two patents that showcase his innovative approach to technology.

Latest Patents

One of Qin Zhang's latest patents is a system for determining the noise content of a video signal. This invention involves digitizing a frame based on the video signal to create a digitized signal, which is then filtered using a high pass filter. The filtered image is divided into multiple subimages, and the noise signal in each subimage is analyzed. The average noise in the selected subimages is determined, along with the signal-to-noise ratio. Additionally, the carrier-to-noise ratio can also be calculated if needed. Another significant patent is a signal quality monitoring system. This system monitors cable television signals and identifies impairments by capturing a portion of a transmitted frame of video information. A two-dimensional Fourier transform is performed on the video signal, allowing for the analysis of specific frequencies to indicate areas of impairment.
