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.
Claims13
A method of controlling a display apparatus which processes and displays an image signal, the method comprising:
- receiving an image data;
- dividing the received image data into an image signal and a metadata;
- acquiring information relating to an area of interest from the metadata;
- and
- performing a high dynamic range (HDR) processing on the area of interest based on the information relating to the area of interest,
- wherein the information relating to the area of interest comprises a coordinate corresponding to the area of interest and color range information relating to a front view and a background included in the area of interest, and
- wherein the performing the HDR processing comprises performing at least one from among a tone mapping and a saturation mapping using a parameter corresponding to the front view and a different parameter corresponding to the background.
A display apparatus which processes and displays an image signal, comprising:
- an image receiver configured to receive an image data;
- a decoder configured to divide the received image data into an image signal and metadata;
- and
- an image processor configured to acquire information relating to an area of interest from the metadata and to perform a high dynamic range (HDR) processing on the area of interest based on the information relating to the area of interest,
- wherein the information relating to the area of interest comprises a coordinate corresponding to the area of interest and color range information relating to a front view and a background included in the area of interest, and
- wherein the image processor is configured to perform at least one from among a tone mapping and a saturation mapping using a parameter corresponding to the front view and a different parameter corresponding to the background.
