1. A method of eliminating image noise, the method comprising: extracting a spatial-temporal noise level of neighbor pixels around a current pixel of a current frame, wherein the extracting the spatial-temporal noise level comprises extracting a spatial edge intensity parameter, a temporal correlation parameter and a spatial-temporal brightness parameter, and generating the spatial-temporal noise level as a summation of the spatial edge intensity parameter, the temporal correlation parameter and the spatial-temporal brightness parameter; filtering noise of the current pixel by applying a weight to spatial-temporal pixels around the current pixel based on the extracted spatial-temporal noise level; and applying a weight to the noise-filtered current pixel and to a boosted-up pixel based on an edge intensity, and summing up the weight-applied pixels.
