1. An image processing apparatus comprising: at least one processor; a memory coupled with the at least one processor and having stored thereon instructions that, when executed by the at least one processor, cause the image processing apparatus to: input a hue signal representing a hue of an image and an image quality signal representing a texture of the image; convert the image quality signal into a physical quantity signal indicating at least a refractive index of a color material corresponding to the image quality signal; and determine a color material dot arrangement for outputting the image by using either quantization method of reproducing an image having blue noise characteristics exhibiting high dispersibility or quantization method of reproducing an image having green noise characteristics exhibiting low dispersibility based on the hue signal and the physical quantity signal, wherein the quantization method of reproducing an image having blue noise characteristics is used in a case where the refractive index is high, and the quantization method of reproducing an image having green noise characteristics is used in a case where the refractive index is low.
