Abstract: Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device and an image display apparatus including the same include: a converter configured to convert of frequency of an input stereo audio signal; a primary component analyzer configured to perform primary component analysis based on a signal from the converter; a feature extractor configured to extract a feature of a primary component signal based on a signal from the primary component analyzer; an envelope adjustor configured to perform envelope adjustment based on prediction performed on the basis of a deep neural network model; and an inverse converter configured to inversely convert a signal from the envelope adjustor to output an upmix audio signal of multi-channel. Accordingly, when upmixing the downmix stereo audio signal to a multichannel audio signal, spatial distortion can be improved.
