Abstract:
An image processing apparatus according to an embodiment of the present invention includes: a first generation unit that generates a low-frequency image by extracting a low-frequency component from an input image; a second generation unit that generates a high-frequency image by extracting a high-frequency component from the input image; a screen processing unit that generates an AM screen image by performing AM screen processing on the low-frequency image; an addition processing unit that generates an added image by adding the high-frequency image to the AM screen image; and a correction unit that corrects the added image.
