An IP conversion unit 20 converts an interlaced image which is an input image into a progressive (non-interlaced) image, and outputs the image. A scene detection unit 30 detects from motion vectors (Mx,My) whether the entire image is being slowly vertically scrolled (outputs a vertical scrolling coefficient tcoef). In a 3D filter 41 of an interlace interference removal unit 40 , when vertical scrolling is detected, parallel motion of a plurality of past output images according to an average motion amount is caused according to motion vectors (Mx,My), cumulative pixel values are calculated, and the pixel values are taken to be the output image during vertical scrolling (interpolated image).
