Abstract
An up-converter (7) performs up-conversion on frame images in a video signal. A pseudo-noise generation circuit (9) generates a pseudo-noise signal, and an adder (10) composites the pseudo-noise signal with the up-converted video signal. As a result, noise having the same resolution as the up-converted frame images (1920 vertical pixels by 1080 horizontal lines) is distributed in the composited frame images, and each piece of noise has a characteristic approximating a characteristic (crest value, amount, or frequency) of noise included in the pre-conversion video signal.
