Abstract

A gamma correction apparatus for a display device, includes: a measurer configured to measure an optical characteristic of a display panel; and a gamma data generator configured to generate measurement gamma data for at least one measurement gray level pre-determined from among a plurality of gray levels, based on the optical characteristic received from the measurer, generate prediction gamma data for at least one prediction gray level other than the at least one measurement gray level from among the plurality of gray levels by using an equation defining a relationship between a gray level and an optical characteristic, and generate gray level-wise gamma data, based on the measurement gamma data and the prediction gamma data.
