PURPOSE: A real time gamma correction method is provided not to require a storing device for storing a gamma value and a calculating device for calculating a floating point square root by implementing gamma correction only by addition, subtraction, multiplication, and division. CONSTITUTION: A first gamma correction output is calculated by using a first gamma value(ST110). A second gamma correction output is calculated by using a second gamma value(ST120). A gamma correction output differential is calculated by subtracting the second gamma correction output from the first gamma correction output(ST130). A third gamma correction output is calculated by multiplying and/or dividing the gamma factor with the gamma correction output differential(ST140). A final gamma correction output is calculated by subtracting the third gamma correction output from the first gamma correction output or adding the third gamma correction output to the second gamma correction output(ST150).
