ABSTRACT:
An image display apparatus is provided for receiving a digital image signal and displaying it so that high-quality images can be displayed with the noise reduced not to be conspicuous and with the contour appropriately corrected. The image display apparatus includes an input unit to which the digital image signal is applied, an information detection/separation circuit which detects and separates frame encoding information and bit rate information from the digital image signal, a picture quality correcting unit which makes contour correction
oise reduction process on the digital image signal, and a control circuit. The control circuit controls the picture-quality correcting unit to make the above process by using the frame encoding information and bit rate information from the information detection/separation circuit.
