Display device and method for operating display device

A display device, comprising:

• at least one camera;
• a plurality of lights;
• memory storing at least one program;
• and
• at least one processor, comprising processing circuitry, electrically connected to the at least one camera, the plurality of lights, and the memory, wherein at least one processor, individually and/or collectively, is configured to execute instructions of the at least one program and to:
• obtain a first image, the first image being a target image, and a second image captured through the at least one camera;
• extract a common component between the first image and the second image;
• split a first area including the common component in the first image into a plurality of first sub areas, and identify an attribute value associated with at least one of a color or a brightness corresponding to each of the plurality of first sub areas as a per-first sub area attribute value;
• split a second area including the common component in the second image into a plurality of second sub areas, and identify an attribute value associated with at least one of a color or a brightness corresponding to each of the plurality of second sub areas as a per-second sub area attribute value;
• determine whether a difference between the per-first sub area attribute value and the per-second sub area attribute value is within a specified range;
• based on a result of the determination, identify that a difference between at least one first attribute value corresponding to at least one third sub area among the plurality of first sub areas and at least one second attribute value corresponding to at least one fourth sub area among the plurality of second sub areas is not within the specified range;
• based on the at least one first attribute value, determine a setting value of at least one light associated with the at least one fourth sub area among the plurality of lights;
• and
• control the at least one light based on the determined setting value.
