Fig. 1 is please referred to, Fig. 1 shows the structural schematic diagram of chip 100 provided in an embodiment of the present invention.Chip 100 can be with
It is the chip with image-capable, for example, monitoring chip, picture processing chip etc..Chip 100 and image collecting device 10
Electrical connection, chip 100 include data receiver 110, microcontroller 120, image processing module 130 and memory 140, and data connect
Receiving end 110 is electrically connected with image collecting device 10, microcontroller 120 and data receiver 110 and image processing module 130 electricity
Connection, data receiver 110 is electrically connected with image processing module 130 and memory 140 simultaneously, and 130 He of image processing module
Memory 140 is electrically connected.
In the present embodiment, data receiver 110 is electrically connected with image collecting device 10, for receiving image collecting device
The raw image data of 10 acquisitions, image collecting device 10 can be camera, imaging sensor etc..Raw image data is figure
The big resolution ratio non-real-time data acquired as acquisition device 10.
In the present embodiment, microcontroller 120, for raw image data to be divided at least two according to preset rules
Divided data, wherein adjacent two parts data include repeated data.Preset rules include preset data processing width and default weight
Complex data width, default repeated data width can indicate with padding num, and the data width of repeated data is twice pre-
If repeated data, that is, the data width of repeated data can be expressed as padding num*2.Microcontroller 120, be also used to by
Width and default repeated data width are handled according to preset data, raw image data is divided at least two parts data, below
It describes in detail.
It is possible, firstly, to determine the data for needing to reprocess according to the filter radius of filter in image processing module 130
Width, that is, default repeated data width, default repeated data width can be indicated with padding num.Image processing module
It is all to be filtered according to point or block when filter is filtered in 130, in order to avoid being introduced due to boundary filtering difference
Image boundary, need according in image processing module 130 filter filter radius increase reprocessing data, for example, figure
As, there are two the filter being filtered according to block, one filter radius is 3, another filtering is partly in processing module 130
Diameter is 5, then the minimum for presetting repeated data width should be set as 8, that is, padding num=8.Determining default weight simultaneously
When complex data width, it is also necessary to consider that alignment of data operates.
Secondly, the resolution ratio for the maximum width and raw image data that can be handled according to chip 100, calculates original image
Data need the number divided, that is, the split screen number of 130 split screen of image processing module processing raw image data, for example, core
Piece 100 is maximum to support 2,000,000 (1920x1080) resolution ratio, under the premise of picture altitude is unrestricted, if original image number
According to resolution ratio be 4,000,000 (2688x1520), then raw image data will at least be divided into two parts, that is, original graph
As data will at least be divided into 2 panes, i.e., left half screen and right half screen；If the resolution ratio of raw image data is 8,000,000
(3840x2160), then raw image data will at least be divided into three parts, that is, raw image data will be at least divided
For 3 panes, i.e., left half screen, intermediate half screen and right half screen.
It should be pointed out that above-mentioned is the split screen processing under the premise of chip 100 does not limit picture altitude, such as fruit chip
100 is restricted for picture altitude, and the resolution ratio of raw image data has exceeded the maximum height limit of chip 100, then also needs
Divide the height of raw image data.For example, chip 100 is maximum to support 2,000,000 (1920x1080) resolution ratio, while chip
100 have picture altitude 1080 limitation, if the resolution ratio of raw image data is 4,000,000 (2688x1520),
Raw image data will at least be divided into four split screens, i.e. upper left half screen, upper right half screen, lower-left half screen and bottom right half screen.
Next, determine that preset data handles width according to default repeated data width padding num and split screen number,
Preset data width is exactly the width that raw image data is divided to later each section data, that is, image processing module

The default repeated data width that the data width of complex data is twice, the i.e. data width of repeated data are padding num*2.
By taking raw image data is divided into 3 panes as an example, referring to figure 2., the left side of the right side of Zuo Banping and intermediate half screen includes number
According to the repeated data for the default repeated data width that width is twice, the left side of the right side of intermediate half screen and right half screen includes data
The repeated data for the default repeated data width that width is twice.Preset data, which handles width, to be no more than 100 energy of chip
The maximum width of processing is freely specified under the premise of meeting image alignment requirement again, it is not limited here.
After determining preset data processing width and default repeated data width, microcontroller 120 is according to preset data
Width and default repeated data width are handled, raw image data is divided at least two parts data, at least two parts number
According to including the first data and other data in addition to the first data.First data are that data receiver 110 receives earliest
A part of data, it is, data receiver 110 receives the timing of the first data earlier than other data.For example, if original
Image data is divided into 2 panes, then the first data are Zuo Banping, other data are right half screen；If raw image data quilt
3 panes are divided into, then the first data are Zuo Banping, other data are intermediate half screen and right half screen.
In the present embodiment, data receiver 110, after being also used to division under the control of microcontroller 120 at least
The first data transmission in two parts data to image processing module 130, will be at least in two parts data in addition to the first data

Right side and intermediate half screen left side include the default repeated data width that data width is twice repeated data, intermediate half screen
Right side and right half screen left side include data width be twice default repeated data width repeated data, then by each portion
Divided data processing is after image, it is only necessary to be cut repeated data, since repeated data corresponds to two parts data
Adjacent image, then it is twice of default repeated data width that adjacent two parts image needs cut data width altogether
The repeated data of (padding num*2), that is, it is default repeated data width that every parts of images, which only needs to cut width,
The data of (padding num).For example, needing to cut default repeated data width (padding in Fig. 2, on the right side of Zuo Banping
Num data), the left and right side of intermediate half screen be required to cut the data of default repeated data width (padding num),
Need to cut the data of default repeated data width (padding num) on the left of right half screen.
