Abstract: A display apparatus which processes and displays an image signal and a method of controlling the same are provided. The method includes receiving an image data, dividing the received image data into an image signal into an image signal and a metadata, and acquiring information relating to an area of interest by using the metadata and performing a high dynamic range (HDR) processing with respect to the area of interest by using the acquired information relating to the area of interest.

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.
