Abstract
An image processing apparatus of the present embodiment generates image data representing an image which reproduces anisotropy. The image processing apparatus of the present embodiment has a receiving unit configured to receive an input of image data having anisotropy information and a generating unit configured to generate a signal corresponding to a printing material based on the anisotropy information. The generating unit generates an ejection signal so that a first area and a second area have different smoothnesses, the first area being formed by the printing material adjacently ejected in a first direction, the second area being formed by the printing material adjacently ejected in a second direction, the second direction being different from the first direction.

An image processing apparatus for generating image data representing an image which reproduces anisotropy, wherein a degree of scattering of surface reflected light from the image changes depending on a direction in an image plane, the image processing apparatus comprising:
- a receiving unit configured to receive an input of image data having anisotropy information;
- an obtaining unit configured to obtain, from the anisotropy information of the input image data, information regarding a first reflection intensity of specular reflected light in a first direction in the image plane and a second reflection intensity of specular reflected light in a second direction in the image plane different from the first direction;
- and
- a generating unit configured to generate a signal corresponding to ejecting an ink as a printing material on a print medium based on the obtained information,
- wherein the generating unit is configured to generate the signal differentiating, based on the obtained information, a time difference between elections of the printing material for arranging pixels adjacently in the first direction on the print medium from a time difference between elections of the printing material for arranging pixels adjacently in the second direction on the print medium, and
- wherein the time difference between elections of the printing material for arranging pixels adjacently is set to be equal to or less than a threshold to form a smooth area for reducing scattering in the arranging direction and the time difference between ejections of the printing material for arranging pixels adjacently is set greater than the threshold to form fine roughness for increasing scattering in the arranging direction.
