Abstract:
1. A display device, comprising: a frame rate conversion section performing frame rate conversion through performing a frame interpolation process on a composite picture frame with use of a motion vector, the composite picture frame being generated through superimposing an on-screen display (OSD) picture region on a picture frame; a mask generation section generating a mask region based on a flag signal, the flag signal indicating a first region of the composite picture frame that is superimposed by the OSD picture region; and a display section performing picture display based on a frame-rate-converted composite picture frame provided from the frame rate conversion section, wherein the mask region creates a boundary of at least one pixel between the first region and a second region of the composite picture frame that is not superimposed by the OSD picture region, and the frame rate conversion section selectively performs the frame interpolation process to each pixel or to every plural pixels in the second region of the composite picture frame.
