Abstract
A method of deinterlacing includes generating a deinterlaced display frame including a reference field of lines of display pixels of a first parity and a generated field of lines of display pixels of a second parity. A frame motion map is generated which includes bits representing a presence of motion or an absence of motion at the display pixels of the reference and generated fields. Testing is performed for the presence of motion or the absence of motion at a selected display pixel of the reference field utilizing the frame motion map. In response to detecting a presence of motion at the selected display pixel of the referenced field, replacing a pixel value corresponding to the selected display pixel with a pixel value generated by interpolating between display pixel values corresponding to neighboring display pixels in the generated field.
