Patent JP-2006514326-A (JP)
IPC: G11B20/00
Filed: 2003-02-21
Abstract: The invention relates to a method for embedding and detecting a watermark in a digital audio signal. For embedding the watermark in the digital audio signal a modified-segment (S<SUB>out</SUB><SUP>(t)</SUP>) is created from a selected input-segment (s<SUB>in</SUB><SUP>(t)</SUP>) of the digital audio signal. The modified-segment (s<SUB>out</SUB><SUP>(t)</SUP>) is created such, that at least one of two sub-segments ((s<SUB>sub</SUB> , 1 <SUP>(t)</SUP>(s<SUB>sub</SUB> , 2 <SUP>(t)</SUP>) of the input-segment (s<SUB>in</SUB><SUP>(t)</SUP>) is time-shifted (dt) such that in an overlapping zone (L<SUB>ov</SUB>) a correlation value of the two sub-segments (s<SUB>sub</SUB> , 1 <SUP>(t)</SUP>, (s<SUB>sub</SUB> , 2 <SUP>(t)</SUP>) is a maximum. The signal (s<SUB>ov</SUB>(t)) in the overlapping zone (L<SUB>ov</SUB>) is then created as a weighted average of the two sub-segments ((s<SUB>sub</SUB> , 1 <SUP>(t)</SUP>, (s<SUB>sub</SUB> , 2 <SUP>(t)</SUP>) in said overlapping zone. For detecting the embedded watermark in a received digital audio signal (x(t)), a first template-signal (h1 (t)) and a second template-signal (h2(t)) are generated. Then a first (c1) and a second (c2) correlation value are created by comparing the first (h1(t)) and second (h2(t)) template-signal with the received digital audio signal (x(t)). Finally, it is assumed that a watermark is included in the received digital audio signal, if the second correlation value (c2) is higher than the first correlation value (c1).

Abstract: <P>PROBLEM TO BE SOLVED: To provide an image forming method and an image forming apparatus by which an optional image is formed like a watermark on demand by a printer.  <P>SOLUTION: Letters XYZ to be formed in a watermark pattern are formed in process black by using toner YMC, and a solid image is formed on the letters so as to cover with toner K. Since both of the image formed with the toner YMC and the image formed with the toner K are recognized as black under reflected light, they only look like the solid image as a whole. However, since light is absorbed not only by the toner YMC but also by the toner K in the letter part under transmitted light, the transmittance of the light gets lower than in other parts. Therefore, the letters are recognized under the transmitted light.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
