ABSTRACT:
A judder detection apparatus, a de-interlacing apparatus using the judder detection apparatus, and a de-interlacing method. The judder detection apparatus includes a judder detector to detect whether a detected pattern that is similar to a judder pattern occurs using predetermined pixel values of even and odd fields sequentially input, a pattern detector to detect whether an input image has a uniform pixel value in every other line of the even and odd fields and whether consecutive lines of the even and odd fields have a blind pattern having a difference from the uniform pixel that is greater than or equal to a threshold value, and a determiner to determine whether the detected pattern that is similar to the judder pattern is a judder based on whether the blind pattern is detected.
