Discussion on the Influence of Background Brightness on the Image Performance Test of Medical Endoscope Video Camera System
The SNR test method of YY/T 1587-2018"Electronic Endoscope for Medical Endoscope"is the same as that of YY/T 1603-2018"Camera System for Endoscope Supply Device for Medical Endoscope",which adopts linear interpolation method to find out the SNR with Y value of 0.707.Based on the polynomial fitting method of Weierstrass approximation theorem,this paper analyzes the SNR interpolation,compares and discusses the results with the piecewise-linear interpolation,and puts forward some supplementary suggestions for the test conditions.
