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.

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 signal processormay include an OSC processor configured to upscale an OSC having a first resolution to a second resolution greater than the first resolution; and a synthesizer configured to synthesize at least a part of an image having the second resolution and the upscaled OSD having the second resolution, and the OSD processor outputs the OSD having the second resolution, in which luminance and transparency are adjusted.

Signal processing device and image display apparatus including the same capable of increasing clarity of OSD when mixing with image

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.

Provided are a device and method for detecting watermarks in content carrying watermarks. One method for watermark detection according to the present invention comprises the steps of: extracting the label of a frequency component of the content; generating a bit sequence by making bit values correspond on the basis of changes in the label being extracted; checking correlation while shifting the phase of the band-spreading code (pn sequence) with respect to the generated bit sequence; and checking the amount of phase shift in the band-spreading code at times when the correlation checked in this way falls into the category of autocorrelation, and then determining a bit group having a value corresponding to the amount of phase shift checked in this manner. The bit group determined in this way constitutes part of watermark data.
