Light source optimization apparatus and light source optimization method

A light source optimization apparatus, comprising:

• a storage apparatus storing a plurality of modules;
• and
• a processor coupled to the storage apparatus and configured to execute the plurality of modules, wherein the plurality of modules comprise:
• a critical pattern module retrieving critical pattern data;
• and
• a light source optimization module executing an ant colony optimization (ACO) algorithm according to a preset parameter to adjust an initial light source image to generate an output light source image, wherein the initial light source image corresponds to the critical pattern data, and the preset parameter includes a number of ants,
• wherein the processor is further configured to control the light source optimization module to calculate the number of ants based on a dimension of the initial light source image and m values that each pixel of the initial light source image corresponding to, wherein m is an integer.
