Abstract: Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device of an embodiment of the present disclosure includes: a quality calculator configured to calculate a source quality of an image signal received from an external settop box or a network; an image quality setter configured to set an image quality of the image signal based on the calculated source quality; and an image quality processor configured to perform image quality processing on the image signal based on the set image quality, wherein in response to the source quality of the received image signal being changed at a first time point, the image quality setter changes an image quality setting sequentially from a first setting to a second setting; and based on the image quality setting, the image quality processor performs image quality processing. Accordingly, flicker may be reduced when an image quality is changed due to a change in the source quality of the received image signal.

Abstract: A digital device and a control method thereof are disclosed in the present specification. The digital device and the control method thereof according to the present invention may comprise the steps of receiving an image signal; separating the received image signal by a plurality of frequency bands; adjusting a gain for the image signal of each of the separated frequency bands; displaying an enhanced image on a screen by synthesizing the image signals of the respective frequency bands in which the gain has been adjusted; separating the screen, on which the enhanced image is displayed, into a plurality of areas; checking whether the maximum pixel value of the enhanced image displayed on the separated screen area, if the maximum pixel value of the enhanced image is larger than the reference value.
