An image processing apparatus comprises: a division unit which divides the input image data into blocks each including a predetermined number of pixels; a determination unit which determines whether the number of colors that is the number of types of colors of the pixels included in the block is not less than a predetermined number; a pseudo halftone processing unit which performs pseudo halftone processing of image data for the block if the number of colors in the block is not less than the predetermined number; an acquisition unit which acquires a color arrangement and color information in each of the block, in which the determination unit determines that the number of colors is less than the predetermined number, and the block having undergone the pseudo halftone processing; and a storage unit which stores the color arrangement and the color information, acquired, for each block.
