1. A display device, comprising:
a receiver;
a display;
at least one memory storing instructions; and
at least one processor configured to execute the stored instructions to:
receive an input image through the receiver;
identify pixels having a luminance value greater than or equal to a reference value from a plurality of pixels of the input image;
extract pixels including feature information from the identified pixels based on luminance values of the identified pixels and luminance values of neighboring pixels of the identified pixels, the feature information including at least one of edge information, texture information and gradation information;
map the luminance values of the identified pixels to output luminance values, based on a histogram of the extracted pixels; and
display, on the display, an output image including pixels having the output luminance values.
