Abstract
According to one embodiment, an apparatus includes an average calculation portion which performs a average calculating process between frames by use of an input signal and one-frame delay signal and acquires an output signal having cross color and dot disturbance components reduced, and an up-convert signal detecting portion which sets the inter-frame mean delay processing portion into an operative state when the input signal is an up-convert signal obtained by up-converting a low-resolution signal into a high-resolution signal.
