It wherein, include delay subelement II, the not reconstructed image data input port input of reconstructed module in reconfiguration unit
Image data by delay subelement and reconstructed image data output port is not exported.
The reason similar with decomposing module, since wavelet transformation needs to guarantee that image data total amount is constant, it is necessary to carry out
Wshift operation.For each frame image, (due to down-sampled, image data total amount needs the calculated result of several rows of storage beginning
Will be except 2 operations), and read from storage region finally, it is added with the calculated result of last rows, to reduce boundary to figure
As the influence of processing.Referring specifically in attached drawing 5, storage region II includes that the storage of row data and frame level do not store, wavelet basis
Length is N, and when N is odd number greater than 1, storage region II stores the line number of N row accordingly and the frame number of levels of (N-1)/2 row
According to；When N is even number greater than 1, storage region II, which store, stores the line number of N row accordingly and the other data of the frame level of N/2 row.
The port of processing module and decomposing module are essentially identical in the present invention, and specific structure can be according to processing module
Processing mode etc. is specifically determined, unquestionable, is also needed that image data will be handled in processing module and is not located
Reason image data distinguishes.
As shown in Fig. 6, be wavelet basis length it is 6, and decomposes by two-stage and the Embedded Wavelet circuit of two-stage reconstruct.
The decomposition image data-in port of 1st grade of decomposing module does not decompose image data input mouth and control signal input mouth
The pictorial data representation inputted respectively are as follows: D1_ IN, DUP1_ IN and CTRL1_ IN, due to the decomposition picture number of the 1st grade of decomposing module
According to output port, image data output port is not decomposed and control signal output mouth is separately connected point of the 2nd grade of decomposing module
Xie Tuxiangshuojushuruduankou, image data input mouth and control signal input mouth are not decomposed, so the 2nd grade of decomposing module
Decomposition image data-in port, do not decompose the image that image data input mouth and control signal input mouth input respectively
Data are expressed as: D2_ IN, DUP2_ IN and CTRL2_ IN, the decomposition image data-out port of the 2nd grade of decomposing module do not decompose
The image data that image data output port and control signal output mouth are exported respectively indicates are as follows: D2_ OUT, DUP2_ OUT and
CTRL2_ OUT, and be passed through the decomposition image data-in port of processing module ISP, do not decompose image data input mouth and control
In signal input port processed, the reconstructed image data output port of processing module ISP, not reconstructed image data output port and control
Signal input port processed is separately connected that the 2nd grade of reconstructed module includes reconstructed image data input port, reconstructed image data is not defeated
Inbound port and control signal input mouth.The reconstructed image data input port of 2nd grade of reconstructed module, reconstructed image data is not defeated
The pictorial data representation that inbound port and control signal input mouth input respectively are as follows: B2_ IN, BUP2_ IN and CTRLO2_ IN, due to
The reconstructed image data output port of 2nd grade of reconstructed module, not reconstructed image data output port and control signal output mouth
It is separately connected reconstructed image data input port, not reconstructed image data input port and the control signal of the 1st grade of reconstructed module
Input port, so the reconstructed image data input port of the 1st grade of reconstructed module, not reconstructed image data input port and control
The pictorial data representation that signal input port inputs respectively are as follows: B1_ IN, BUP1_ IN and CTRLO1_ IN, the 1st grade of reconstructed module
The picture number that reconstructed image data output port, not reconstructed image data output port and control signal output mouth input respectively
According to expression are as follows: B1_ OUT, BUP1_ OUT and CTRLO1_ OUT, wherein B1_ OUT and BUP1_ OUT is respectively indicated by small wave circuit point
Solution reconstruct after image data and without process decomposed and reconstituted image data.
Due to the row storage for storing the other image data of frame level, can be omitted in the 1st grade of decomposing module, therefore, the 1st
Storage region only needs to store the image data of 6 rows in grade decomposing module.
The above description is only a preferred embodiment of the present invention, and the embodiment is not intended to limit patent protection of the invention
Range, thus it is all with the variation of equivalent structure made by specification and accompanying drawing content of the invention, it similarly should be included in this
In the protection scope of invention appended claims.
