ABSTRACT:
A pattern generating apparatus includes a sequence generating unit and an image data generating unit. The sequence generating unit generates a sequence formed by terms having M-value numeric values. The image data generating unit generates the image data by converting each numeric value of the sequence into a gray-level value according to each numeric value, and the sequence is generated by the sequence generating unit. The sequence generating unit generates the sequence such that vectors expressed by sub-sequences have different directions for the sub-sequence constituting the generated sequence.
