Abstract: A display apparatus is provided. The display apparatus according to an exemplary embodiment includes a display, and a processor configured to generate a second image and a third image where a dynamic range is expanded by respectively applying a first gain and a second gain to an input first image, generate a degraded image of the second image by applying a predetermined degradation model to the second image, based on a difference value between a pixel of the degraded second image and a pixel of the third image satisfying a predetermined condition, modify a pixel value of the second image based on the difference value, and output the second image where the pixel value is modified through the display.

Abstract: A device may receive a request associated with adjusting the media output level of a sink device that is configured to output media content. The device may identify a source gain of a source device that is configured to provide the media content to the sink device, and a sink gain of the sink device. The device may identify a sink adjustment value for changing the sink gain based on the request for adjusting the media output level of the sink device, the source gain, and the sink gain. The device may transmit, to the sink device, a control signal to permit the sink gain to be changed based on the sink adjustment value. The media output level of the sink device is based on the source gain and the sink gain.

Abstract: A content providing apparatus is disclosed. The content providing apparatus comprises: a communication unit for communicating with an external apparatus; an image processing unit for generating a compressed image by image-processing an input original image; and a control unit for controlling the communication unit to divide the original image into one or more regions based on the image quality, to obtain characteristic information for each region from the respective regions, and to transmit the obtained characteristic information for each region together with the compressed image to the external apparatus. As the result, the display apparatus may perform image quality improvement operation so that the image quality is close to the original quality level by extracting information required for improving the image quality and transmitting the same together with a compressed image in production and encoding steps before transmitting the image.
