The present invention provides a bonded substrate fabricated to have its final active layer thickness of 200 nm or lower by performing the etching by only 1 nm to 1 μm with a solution having an etching effect on a surface of an active layer of a bonded substrate which has been prepared by bonding two substrates after one of them having been ion-implanted and then cleaving off a portion thereof by heat treatment. SC-1 solution is used for performing the etching. A polishing, a hydrogen annealing and a sacrificial oxidation may be respectively applied to the active layer before and/or after the etching. The film thickness of this active layer can be made uniform over the entire surface area and the surface roughness of the active layer can be reduced as well.

A color conversion module 42 carries out color conversion of original color image data Grgb from the RGB color system into the CMYK color system to obtain color-converted original color image data Gcmyk (step S104). A DCT module 44 applies DCT (discrete cosine transform) over the whole color-converted original color image data Gcmyk to generate DCT coefficients Dcmyk (step S106). An embedding module 46 embeds the watermark information s into the components C, M, Y, and K of the DCT coefficients Dcmyk (step S108). An IDCT module 48 applies IDCT (inverse discrete cosine transform) onto DCT coefficients D'cmyk with the watermark information s embedded therein to generate embedding-processed color image data G'cmyk (step S110). The color conversion module 42 carries out color conversion of the embedding-processed color image data G'cmyk from the CMYK color system into the RGB color system to obtain embedding-processed color image data G'rgb (step S112). This arrangement does not require any correction of the position or the shape of image blocks in the process of extracting the embedded watermark information.

An image processing apparatus is provided which offers higher versatility than conventional image processing apparatuses. When an input signal to a spatial filtering block is a monochrome signal that contains Y component only, a selector selects its input terminal and a selector selects its input terminal. Then, a low-pass filter output signal of a programmable spatial filter is inputted to a spatial filter, and a low-pass filter output signal of the spatial filer is inputted to a spatial filter. That is, the programmable spatial filter and the spatial filters are connected in series (in cascade), and the cascade-connected three spatial filters perform filtering operation. In this example, low-pass filters with 5×5 taps are connected in cascade in three stages, which enables low-pass filtering with 13×13 taps.

A two-step method resource treatment process for sludge containing oil is composed of two steps of hot emulsion breaking phase separation and normal temperature air float separation. Sludge containing oil is melted with hot water with the volume of 2-5 times of the volume of the sludge, mixed liquid is in a fluidized state, the mixed liquid of the sludge containing oil is mixed with a compound emulsion breaking agent through a mixer to enter a three-phase separator, and three-phase separation of oil, sludge and water is achieved by slowly stirring the mixed liquid. Oil in a fluidized state atthe upper layer overflows out of the separator to enter an oil recycling tank, and sludge-water mixed water at the lower layer is cooled by a heat exchanger A to enter the air float separator to be separated at the normal temperature. Oil at the upper layer of the air float separator enters the oil recycling tank, and sludge-water mixed liquid at the lower layer is sent into a centrifugal machineto perform sludge-water separation.
