ABSTRACT:
According to one embodiment, an image processing apparatus includes a scaling converter, a luminance histogram detector, a determination module, and a super resolution processor. The scaling converter converts a first image signal to a second image signal having more pixels. The luminance histogram detector detects a luminance histogram. The determination module determines whether the second image signal includes a graphics image based on the luminance histogram. The super resolution processor converts the second image signal to a third image signal with a higher resolution than that of the second image signal, and performs sharpening based on the reference gain. When the second image signal includes a graphics image, the super resolution processor sets the gain of sharpening below the reference gain.
