Classification: CPC B  H | IPC B  H

Claim 12:
13. The image processing device according to claim 11, wherein
the acquisition unit
acquires, when representing an image in a three-dimensional third space adjacent to the first space, third image data indicating a gradation value of an image to be displayed by each of a plurality of pixels in the third space, wherein
the generation unit
generates third display data by quantizing a gradation value indicated by the third image data using a three-dimensional third dither mask having a plurality of threshold values corresponding to a plurality of pixels in the third space, wherein
the first space
is divided into a third subspace and a fourth subspace, wherein
the three-dimensional third dither mask
has a plurality of threshold values disposed so as to exchange a relative positional relationship between
a plurality of threshold values existing in the third subspace and
a plurality of threshold values existing in the fourth subspace
of a plurality of threshold values, corresponding to a plurality of pixels in the first space, that the three-dimensional first dither mask has, wherein
a direction in which the second space is located when viewed from the first space
is different from a direction in which the third space is located when viewed from the first space, and wherein
a direction in which the second subspace is located when viewed from the first subspace
is different from a direction in which the fourth subspace is located when viewed from the third subspace.
