Method for providing image and electronic device for supporting same

A method of providing an image by an electronic device, the method comprising:

• obtaining a first image to which high dynamic range (HDR) is applied and metadata corresponding to the first image;
• scaling up or down, using a scaling ratio based on size information about a first size of the first image and a second size of a second image to be displayed on a display of the electronic device, the first image to a third image;
• obtaining, based on the metadata, first information about a plurality of first areas of the first image;
• obtaining second information about a plurality of second areas of the third image, based on the scaling ratio and the first information;
• and
• obtaining the second image by performing tone mapping on the plurality of second areas using a tone mapping coefficient included in the metadata.

An electronic device comprising:

• a display;
• a memory storing instructions;
• and
• a processor operably coupled to the display and the memory, the processor being configured to execute the instructions to:
• obtain a first image to which high dynamic range (HDR) is applied and metadata corresponding to the first image,
• scale up or down, using a scaling ratio based on size information about a first size of the first image and a second size of a second image to be displayed on the display, the first image to a third image,
• obtain, based on the metadata, first information about a plurality of first areas of the first image,
• adjust at least one of a first value corresponding to a low gray scale or a second value corresponding to a high gray scale in a tone mapping coefficient included in the metadata, and
• obtain the second image by performing tone mapping on an area of the third image using the tone mapping coefficient including the adjusted first value and second value.
