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 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 first image frame data output from the output interface is more delayed than the second image frame data output from the output interface. Accordingly, a timing controller may accurately and rapidly perform signal processing for a panel.

Abstract: The present disclosure relates to a signal processing device and an image display apparatus including the same. The signal processing device 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 in comparison with the first image frame data; and an output interface 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 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: Disclosed are an image display device and an image processing method thereof. A signal processing method of the image display device according to the present invention is a signal processing method of an image display device configured to receive an image having a varied vertical synchronization signal, including detecting an input synchronization signal using an input image clock, extracting an input vertical synchronization signal from the input synchronization signal, delaying the input vertical synchronization signal by a reference value of an output clock, continuously tracking a falling region of the delayed input vertical synchronization signal, and finally generating an output synchronization signal in which a vertical front porch is varied.
