One, which acquires image as kitchen, carries out same treatment to obtain corresponding block-by-block processing image, and the multiframe block-by-block of acquisition is handled
Image replaces multiframe kitchen acquisition image respectively and is sent to image sharpening equipment.
9. hot water flow fixed mechanism in toilet as claimed in claim 8, it is characterised in that:
The block-by-block processing equipment divides the noise in kitchen acquisition image for receiving the kitchen acquisition image
It analyses to obtain the amplitude of various noises, the credit rating of the kitchen acquisition image is determined based on the amplitude of various noises, in institute
When stating credit rating less than or equal to pre-determined lower limit credit rating, based on the credit rating apart from described pre-determined lower limit quality etc.
Far and near each piecemeal that kitchen acquisition image averaging is divided into corresponding block size of grade, to each piecemeal, being based on should
The pixel value variance of piecemeal selects the recursive filtering of corresponding different numbers to handle to obtain filtering piecemeal, by each filter of acquisition
To obtain block-by-block processing image, the block-by-block processing equipment is also used to be higher than pre-determined lower limit in the credit rating combination of wavelength-division block
When credit rating, to the processing of kitchen acquisition image overall execution single recursive filtering to obtain block-by-block processing image；It is based on
It includes: to each that the pixel value variance of the piecemeal, which selects the recursive filtering of corresponding different numbers to handle to obtain filtering piecemeal,
The pixel value variance of piecemeal, the piecemeal is smaller, and the recursive filtering number of processing of selection is more；
Wherein, the block-by-block processing equipment is ROM type MCU chip in no piece, the external EPROM of ROM type MCU chip in the no piece
Chip.
