According to one embodiment, an image processing apparatus includes a level storage module, an instruction receiving module, a switching module, and a resolution increasing module. The level storage module stores a super-resolution level in association with a video mode that indicates definition to display a video signal. The super-resolution level indicates intensity of super-resolution conversion, in which from a video signal having first resolution, a video signal is obtained that has second resolution higher than the first resolution. The instruction receiving module receives an instruction specifying a video mode. The switching module switches a video mode to the specified video mode. The resolution increasing module performs the super-resolution conversion at a super-resolution level corresponding to the specified video mode.
