摘要：
In a watermark processing system, a watermark detector detects first information represented by a watermark from an image, a watermark encoder decodes and error-corrects the first information and re-encodes it to second information, and a watermark eraser identifies the position of the tint-block pattern included in the watermark according to the second information and produces a watermark-erased image from which the watermark is erased.
