## Abstract

A mathematical model of quantum noise having much effect on the low-light-imaging system is set up. To simulate the quantum noise, the random numbers obeying noise distribution must be formed and are weighted on the basis of the model created. Three uniform random sequences are built by the linear congruential method, of which two are used to form integer number and decimal fraction parts of the new random sequence respectively and the third to shuffle the new sequence. And then a Gauss sequence is formed out of uniform distribution by a function transforming method. It actualizes the simulation in real time of quantum noise in the low-light-imaging system, where video flow is extracted in real time, the noise summed up and played back side by side with the original video signs by a simulation software.
