ABSTRACT:
According to one embodiment, an IP converter converts an interlaced color difference signal, in which the number of pixels in a vertical direction of a color difference signal is half that of a luminance signal, into a progressive color difference signal. A diagonal correlation detector detects a diagonal correlation of the progressive color difference signal, and obtains a correlative direction detected signal. A controller outputs a field selection signal to determine whether the progressive color difference signal is a signal in a top or bottom field. And a pixel generator changes a ratio between pixels of an nthand an n+1thline of the progressive color difference signal according to the field selection signal, when generating a new pixel by using corresponding pixels of the nthand n+1thlines based on the correlative direction detected signal.
