Abstract: An image display apparatus includes a display, an image receiver to receive a high dynamic range image, and a controller to set luminance information of an image to be displayed based on brightness information of the high dynamic range image and information about a luminance that is displayable on the display and to perform control to display an image having a luminance adjusted based on the set image luminance information. Accordingly, the image display apparatus is capable of converting and displaying the high dynamic range image so as to match the luminance that is displayable on the display.

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 signal processing device and an image display apparatus including the same are disclosed. A signal processing device and an image display apparatus including the same according to an embodiment of the present disclosure includes: an afterimage analyzer to calculate image accumulation information based on an input image, an afterimage learning processor to perform learning based on the image accumulation information and adjust an afterimage reducing strength based on the learning, and an afterimage reducing processor to perform an afterimage reducing process based on the afterimage reducing strength from the afterimage learning processor. Accordingly, an afterimage of the image display apparatus including the organic light emitting diode panel may be reduced.
