An image display apparatus includes an input range discriminator which discriminates a type of an input digital video signal, on the basis of a setup level and a dynamic range of the digital video signal; a signal processor which corrects the setup level and the dynamic range of the digital video signal, on the basis of a result of the discrimination made by the input range discriminator; and a display device which displays a picture based on the digital video signal corrected by the signal processor.
