Abstract: The present disclosure relates to a signal processing device and an image display apparatus including the same. The image display apparatus includes a display, an image receiver configured to receive an input image, and a signal processing device configured to perform signal processing of the input image from the image receiver and to output image data to the display, wherein, when a luminance deviation of a first input image is greater than a luminance deviation of a second input image, the signal processing device controls a luminance adjustment change rate of a first input image to be less than a luminance adjustment change rate of the second input image. Accordingly, contrast of an image displayed on the display is improved.

Abstract: The present invention relates to a system and a method for device pairing which can pair a plurality of terminals using a brightness value change pattern. The system for device pairing according to an embodiment of the present invention comprises: an apparatus including a display; n terminals; and a server for connecting the apparatus including the display with the n terminals. The server assigns an ID to the apparatus including the display in accordance with an access request of the apparatus. The apparatus including the display calculates a brightness value change pattern corresponding to the ID, and outputs the pattern on the display. The n terminals can identify the ID after detecting the pattern outputted on the display using a proximity sensor and an illuminance sensor, transmit the ID to the server, and request an access.

Abstract: Provided is a display device including a controller and a display. The controller may perform tone mapping for adjusting luminance of input image data, and the display may display an image according to an output image data, in which luminance is adjusted by the tone mapping. The controller may generate a base mapping curve from the input image data, analyze depth map information of the input image data, generate a mapping curve, to which the depth map information is reflected, from the base mapping curve, and perform the tone mapping using the mapping curve.
