According to one embodiment, a video signal scaling apparatus converts an input video signal and outputs as a scaling video signal while enlarging or reducing the number of pixels. The video signal scaling apparatus includes an adaptive interpolation circuit converting the input video signal and outputting as an interpolation video signal of which pixels are interpolated, and a scaling circuit converting the inputted video signal and enlarging or reducing the number of pixels with an arbitrary scale. Further, the video signal scaling apparatus includes a selection circuit selectively inputting either of the interpolation video signal outputted from the adaptive interpolation circuit or the input video signal to the scaling circuit based on a selection control signal inputted from external, and a scaling control circuit switching a parameter relating to the conversion at the scaling circuit based on the selection control signal.
