The DCT converter 103 extracts block data 102 of a 8×8 pixel size from the original image 101 and then subjects it to DCT conversion. The quantizer 104 quantizes the DCT coefficient. The movement decision unit 106 obtains the difference between the number V(t) of DCT coefficients obtained by the DCT converter 103 and the number V(t−1) of DCT coefficients of the previous frame previously held. The movement decision unit 106 decides the movement as a large value if the difference exceeds a certain threshold value and decides the movement as a small value if the difference is less than the threshold value. The electronic watermark data inserter 105 extracts electronic watermark data W(j) which matches the location where 8×8 block data is extracted from the electronic watermark data table 109, the picture type and the movement and then inserts it into the data after quantization output from the quantizer 104.

摘要:
An optical fiber grating is manufactured by heating intermittently an optical fiber, provided with a core having residual stress in the longitudinal direction, softening a peripheral cladding of the core, and forming spatial periodical changes for the relative refractive index-difference between the core and the cladding, in the longitudinal direction of the aforementioned optical fiber by having the index of refraction of the core change, through the releasing of the aforementioned residual stress. As a result, an optical fiber grating and the manufacturing method thereof, which do not require expensive equipment and which exhibit high productivity, and furthermore a grating characteristic which is stable over time can be provided.

Disclosed is a toner residual quantity detecting apparatus for detecting a residual quantity of toners in a developing unit. This toner residual quantity detecting apparatus has a temperature sensor, provided in the bottom of the developing unit, for generating an output proportional to a detected temperature and a detecting circuit for detecting the toner residual quantity from the output of the temperature sensor. This temperature sensor detects a difference between temperatures when covered with the toners and when not covered with the toners, thereby detecting the toner residual quantity.
