A deinterlacing apparatus using judder detection includes a motion detection unit to extract an extent of motion between a previous field and a next field according to a pixel of a current field of input image; a film mode decision unit to determine if an input image source is in a film mode; an intra-field interpolation unit to calculate a first interpolation value using surrounding pixel values according to a directional value included in the surrounding pixel values of a pixel to be interpolated in the current field of the input image; an inter-field interpolation unit to calculate a second interpolation value using pixel values of the previous field and the next field corresponding to the pixel to be interpolated in the current field of the input image; and a mixing unit to receive three or more adjacent input lines extracted from the current field and at least one line extracted from a field interpolated in the inter-field interpolation unit and detecting judder, and to selectively output one of an output value of the inter-field interpolation unit and an output value of an intra-field interpolation unit depending on the judder detected.
