Abstract: An electronic device is provided. The electronic device includes a camera, a communication interface, and a processor configured to capture an image of a background of a display device through the camera, to divide the captured image into a plurality of blocks, to compare a target gradation value with gradation values of the each of the plurality of blocks, to adjust the gradation values of the each of the plurality of blocks, and to transmit an image of which the gradation values are adjusted, to the display device through the communication interface, wherein the sizes of the plurality of blocks are identified based on a background pattern of the display device.

Abstract: An electronic device is provided. The electronic device includes a storage; and a processor configured to: identify, based on a luminance value of each pixel included in a global area of an image stored in the storage, a first cumulative distribution of the global area, identify, based on a luminance value of each pixel included in a local area of the image, a second cumulative distribution of the local area, correct the luminance value of each pixel included in the local area based on the first cumulative distribution and the second cumulative distribution to generate a corrected luminance value of each pixel included in the local area, and generate a corrected image signal based on the corrected luminance value of each pixel included in the local area.
