摘要 |
An image processing method creates a lookup table having a plurality of grids. The image processing method includes the steps of selecting a grid having a small difference from a target grid from among grids whose output values are calculated; setting an output value of the selected grid as an initial value; optimizing an output value of the target grid by using the set initial value; and storing the optimized output value as an output value of the target grid.
