A method of generating compensation data for a display device is disclosed that includes acquiring a first captured image by capturing an image displayed on the display device based on reference data having a reference grayscale, acquiring a second captured image by capturing an image displayed on the display device based on evaluation data having a compensation target grayscale, calculating a similarity index based on a difference between the first captured image and the second captured image at a plurality of positions of a display panel of the display device, calculating a quality index based on an actual measured grayscale of the second captured image after compensation of the second captured image, generating a compensation prediction model based on the similarity index and the quality index, and generating the compensation data based on the first captured image, the second captured image, the similarity index, and the compensation prediction model.
