Abstract
A detecting system and method of compression-related noise levels is provided to produce a compressed index of an image. A line buffer temporarily stores a pixel (i, j) and neighboring pixels. An edge filter calculates an edge index for the pixel (i, j). A line filter calculates a line index for the pixel (i, j). A first determination device produces an edge signal according to the edge index and the line index for indicating whether the pixel (i, j) locates at an edge. A first buffer temporarily stores edge signals of the pixel (i, j) and left and right pixels. A second buffer temporarily stores line indexes of the pixel (i, j) and associated pixels. A second determination device produces a ringing signal for the pixel (i, j) according to the edge signals temporarily stored in the first buffer and the line indexes temporarily stored in the second buffer.
