Abstract
From an input video signal, a pixel value of a pixel of notice noted at a certain time t and a proximal pixel group adjacent two-dimensionally around the pixel of notice are sampled, and maximum and minimum values from the proximal pixel value group are selected as candidate pixel values. By performing a specific operation between the pixel value of the pixel of notice and the candidate pixel value group, a judgment is made as to whether a pulse noise is contained in the pixel of notice. On the basis of the judgement, a pixel value is selected from among the pixel value of the pixel of notice and the candidate pixel values and delivered.
