Abstract
According to one embodiment, a de-interlacing apparatus includes: a motion vector detecting section; a full-screen shift detecting section detecting a full-screen shift; a moving-or-still judging section performing a moving/still judgment for a video signal; a moving judgment correcting section correcting a moving/still judgment result to lean toward a moving judgment when full-screen shift is detected; a first interpolation signal generating section generating a first interpolation signal for interpolating a one-field delay signal based on the motion vector and the full-screen shift; a second interpolation signal generating section generating a second interpolation signal for interpolating the one-field delay signal from a current field signal or a two-field delay signal; and an interpolation signal mixing section mixing the first and second interpolation signals to generate a mixed interpolation signal.
