Patent ID: 7940331

Claim:
An edge adaptive de-interlacing apparatus for de-interlacing a target pixel, comprising: a complexity detection module, for detecting complexity associated with the target pixel, wherein the complexity detection module comprises: a first complexity detector, for detecting a first complexity of a luminance distribution curve of a first display line in a first region associated with the target pixel to output a first determination signal; a second complexity detector, for detecting a second complexity of a luminance distribution curve of a second display line in the first region to output a second determination signal; and a logic operational unit, for performing a logic operation according to the first determination signal and the second determination signal to output a control signal; a qualifier, coupled to the complexity detection module, for generating similarity of at least one possible edge angle in response to the control signal; a comparator, coupled to the qualifier for comparing said similarity of the at least one possible edge to select a preferred edge angle; and a mixer, coupled to the comparator for generating pixel data of the target pixel according to the preferred edge angle.
