12. An image processing method comprising:
separating input image data into high-frequency component data and low-frequency component data, the input image data comprising color information;
generating first correction data by color-converting the low-frequency component data using a color conversion matrix;
generating second correction data by adjusting a data value of the high-frequency component data using the first correction data;
summing the first correction data with the second correction data to generate sum data; and
generating first image data by performing color inverse conversion on the sum data using a color inverse conversion matrix.
