Abstract: Provided are a signal processing device and an image display apparatus including the same. The signal processing device and the image display apparatus including the same include a scaler configured to scale input images of various resolutions to a first resolution and a resolution enhancement processor configured to perform learning on the input images having the first resolution and to generate a first image having a second resolution higher than the first resolution. Accordingly, resolution may be stably improved even if input images of various resolutions are input.

Abstract: A signal processing device and an image display apparatus including the same are disclosed. The signal processing device includes a scaler configured to scale input images of various resolutions to a first resolution, a resolution enhancement processor configured to perform learning on the input images and to output a residual image of the first resolution, and an image output interface configured to output an output image of the first resolution based on a scaling image from the scaler and the residual image from the resolution enhancement processor, and the image output interface changes a weight and an application strength of the residual image according to the area of the input image.
