Display apparatus and method of processing image thereof

Abstract

A display apparatus receiving an image signal and processing the image signal to be displayable on the basis of a macro-block is provided. The display apparatus includes an image signal receiving part receiving a coded signal including the image signal and converting the coded signal into a transport stream, an image converting part converting the transport stream into the image signal including the macro-block for each frame and outputting the image signal, a block noise detecting part detecting a noise value at a border area between adjacent macro-blocks of the image signal and comparing the noise value with a predetermined standard value, and a control part providing a feedback signal to control the amplification ratio of the image signal on the basis of the detected noise value. Thus the noise value detected from a border area between blocks in every frame forming the image signal is compared with a predetermined standard value so that the image signal having reduced block noise may be processed to display.
