ABSTRACT:
In detection of noise by comparing a digital input image signal and an output image signal in one previous frame with each other, when the input image signal, the output image signal in one previous frame, and a predetermined reference value are represented by a, b, and x, respectively, and when |a−b|≦x and a−b≠1 are satisfied, the presence of noise is determined.
