Abstract: The present disclosure relates to a signal processing device and an image display apparatus including the same. A signal processing device according to an embodiment of the present disclosure includes: an input interface to receive an image signal; a first image processor to generate first image frame data based on the image signal; a second image processor including a scaler to generate second image frame data scaled down from the first image frame data based on the image signal; and an output interface to receive the first image frame data from the first image processor and the second image frame data from the second image processor and to output the first image frame data and the second image frame data, wherein the scaler generates at least one super pixel or super block based on an image block of the image signal and outputs the scaled down second image frame data including the super pixel or the super block. Accordingly, it is possible to generate the scaled down second image frame data with reduced error as compared to the first image frame data.

Abstract: A display device according to an embodiment of the present invention may process an input image with higher resolution than allowed easily without reconfiguring a hardware system through an image processing unit which divides input image data with first resolution into image blocks of an acceptable size and generating processed image data with second resolution lower than the first resolution.

Accordingly, a timing controller may accurately and rapidly perform signal processing for a panel.
