Electronic apparatus and controlling method thereof

An electronic apparatus comprising:

• a display;
• memory configured to store first spectrum information of the display and first color matching function (CMF) information related to the display;
• and
• at least one processor,
• wherein the memory stores instructions which, when executed, configure the at least one processor to individually or collectively control the electronic apparatus to:
• change setting information of the electronic apparatus based on setting information of an external device in which an NFT is manufactured when an NFT image provided from an NFT management server is displayed on the display, the setting information of the external device including gamut information, brightness information, and gamma information,
• obtain first color measurement data based on a color measurement of a test image when the test image is displayed on the display,
• obtain color calibration information based on the first color measurement data, the first spectrum information, the first CMF information, and second color measurement data, second spectrum information, and second CMF information of the external device, and
• adjust a color of the NFT image displayed on the display based on the obtained color calibration information.

A method of controlling an electronic apparatus, the method comprising:

• changing setting information of the electronic apparatus based on the setting information of an external device in which an NFT is manufactured when an NFT image provided from an NFT management server is displayed on a display, comprising a display panel, the setting information of the external device including gamut information, brightness information, and gamma information;
• obtaining first color measurement data based on a color measurement of a test image when the test image is displayed on the display;
• obtaining color calibration information based on the first color measurement data, first spectrum information dependent on characteristics of the display panel of the electronic apparatus, first CMF information, and second color measurement data, second spectrum information dependent on characteristics of a display panel of the external device, and second CMF information of the external device;
• and
• adjusting a color of the NFT image displayed on the display based on the obtained color calibration information.
