IMAGE DATA GENERATOR, EMBEDDED INFORMATION REPRODUCING DEVICE, AND SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To enhance reproducibility of embedded information in a separated image recording device for recording images in parallel by a plurality of unit image recording sections.SOLUTION: Common embedded image IG of an imaged embedded information DA are embedded in at least two of a plurality of image recording sections to be recorded in parallel with a plurality of unit image recording heads. Each unit embedding sections R1-R5 for embedding information in the image recording sections are placed in a tint part CNT. Since each unit embedding sections R1-R5 are recorded with different unit recording heads, if an error occurs in an image recording with any of unit recording heads, the embedded image IG may be reproduced correctly from the recordings with other unit recording heads. The embedded image IG contains a main portion D1 and error correction parts E1, E2 as a plurality of partial information images, and placements of the partial information images in each unit embedding section R1-R5 are non-identical such that the placements are also ciphered.
