A high-quality image reproducibility is realized by appropriately evaluating a screen processing result and controlling the screen processing. An image processing apparatus includes a first screen processing unit for performing screen processing on input image data using first screen information, an evaluation unit for acquiring an evaluation value of a processing result of the first screen processing unit based on a difference between a low-frequency component of the processing result of the first screen processing unit and a low-frequency component of the input image data, a setting unit for setting screen information acquired by performing calculation using the first screen information and second screen information that is different from the first screen information, according to an evaluation value of a processing result of the first screen processing unit, and a second screen processing unit for performing screen processing on the input image data using the set screen information.
