Abstract
A noise reduction apparatus, in which an occurrence of overcorrection attributed to an erroneous detection is prevented. A storage unit stores a pseudo noise signal generating characteristic. A pseudo noise generating unit sets a signal which may become a source of a noise superimposed on a video signal as a reference input signal and generates a pseudo noise signal corresponding to the superimposed noise using the pseudo noise signal generating characteristic which is stored in the storage unit and which corresponds to the reference input signal. A subtraction unit subtracts the pseudo noise signal from the video signal.
