Abstract
An adaptive intra-field algorithm to de-interlace video data uses two line memories to implement a median filter that can use multiple data points on adjacent lines of display. In a median-mode, the filter outputs the median of the input data to create the value for a location on the intermediate line and can decrease image blurring. But if examination of the two adjacent pixels on two adjacent scan lines is small, as in the case of a vertical image line, the filter operates as a line average filter, to avoid creating image artifacts.
