发明名称 Pull-down detection apparatus and pull-down detection method
摘要 A pull-down detection apparatus includes a pixel comparator at least performing pixel comparison between a subsequent field and a present field and horizontal pixel comparison in the subsequent field and the present field to determine a presence of a pixel change between the subsequent field and the present field, a field comparator determining a presence of an image change between the subsequent field and the present field based on a determination result in the pixel comparator, and a pull-down determinater determining that the input video signal is generated by pull-down processing based on a history of a determination result in the field comparator.
