An object of the present invention is to realize a color correction circuit according to a second order color correction formula in which capacities of memories and an operation time are further reduced. A color correction circuit includes three latches, four memories for dividedly storing correction values, and an adder. A first memory receives first and second color separation signals and a color selection signal as address signals. A second memory receives second and third color separation signals and a color selection signal as address signals. A third memory receives third and first color separation signals and the color selection signal as address signals. A value of a product term of the first and second color separation signals is included in the value of the first memory. A value of a product term of the second and third color separation signals is included in the value of the second memory. A value of a product term of the third and first color separation signals is included in the value of the third memory. Values of linear terms and square terms of respective color separation signals are included in memories to which related color separation signals are input.
