Abstract: The present disclosure relates to a signal processing device and an image display apparatus including the same. The image display apparatus includes a display, an image receiver configured to receive an input image, and a signal processing device configured to perform signal processing of the input image from the image receiver and to output image data to the display, wherein, when a luminance deviation of a first input image is greater than a luminance deviation of a second input image, the signal processing device controls a luminance adjustment change rate of a first input image to be less than a luminance adjustment change rate of the second input image. Accordingly, contrast of an image displayed on the display is improved.
