Motion video generation module 7 forms RGB (color of red, green, blue three) image.
In the step 1, when image level mobile module (4.1) carries out image level movement processing, walked as follows
Rapid processing, move right 1 pixel every time as shown in Figures 2 and 3, in Fig. 2, and this is merely illustrative, and actual mobile number of pixels takes
The translational speed (number of pixels that i.e. upper-layer configured moves every time) certainly configured in upper strata：
Step 101：Image level movement control module 9 controls image memory interface 1 to be read from raw image data and controlled
Original image is taken out in module 3 includes some row view data including the 1st row (to avoid causing because to storage operation
Delay, therefore start once read multirow data buffer storage into raw image data cache module 2) be deposited into original image number
According to cache module 2；
Step 102：The image level movement notification image of control module 9 moves horizontally the image level movement in module 4.1
The number of pixels that module 4.1 moves horizontally every time, image level mobile module 4.1 is according to the default method of operation moved horizontally
Raw image data is controlled to read the respective pixel data that control module 3 reads corresponding row, raw image data reads control mould
The respective pixel data of the corresponding row of above-mentioned reading are transported to image level by raw image data cache module 2 and moved by block 3
In dynamic model block 4.1；
Step 103：Image level mobile module 4.1 moves in control signal according to image level and moves horizontally pixel control
Raw image data processed reads control module 3 and reads the image pixel stored in raw image data cache module 2, concrete mode
It is as follows；
When image level mobile module 4.1 controls image to move horizontally, and horizontal movement velocity is 1 pixel, image
Module 4.1 is moved horizontally to first pass through last pixel of the raw image data reading taking-up the first row of control module 3 and deposit
To moving horizontally in data cache module 5.1, further take out first pixel and be stored in and move horizontally data cache module
In 5.1 follow-up buffer address, last pixel of the first row before the taking-up circulated in this mode after single treatment is simultaneously suitable
Being deposited into for sequence is moved horizontally in the follow-up buffer address of data cache module 5.1, first before further taking out after single treatment
Pixel and being stored in is moved horizontally in the follow-up buffer address of data cache module 5.1, when moving horizontally data buffer storage mould
When block 5.1 is stored in data line, then the row data are then to move horizontally the pixel arrangement of image, every row pixel are carried out above-mentioned
Handling the image pixel after being moved horizontally, (if it is from left to right translational speed is 1 pixel, (as shown in Figure 2) then schemes
Last pixel P (x- for first passing through raw image data as moving horizontally module 4.1 and reading control module 3 and taking out the first row
1,0) and be stored in and move horizontally in data cache module 5.1, further take out first pixel P (0,0) and successively be stored in water
In the dynamic further cache address of data cache module 5.1 of translation, the next pixel of taking-up that so circulates and order are deposited into water
In the continuous buffer address of the dynamic data cache module 5.1 of translation, as shown in Figure 2).
In the step 103 of above-mentioned technical proposal, when image level mobile module 4.1 controls image to move horizontally, and it is horizontal
Translational speed is n pixel, and during n ＞ 1, then image level mobile module 4.1 reads control module 3 by raw image data
Take out the last n pixel of the first row and be stored in and move horizontally in data cache module 5.1, further take out n picture before the first row
Element is simultaneously stored in and moved horizontally in the follow-up buffer address of data cache module 5.1, before the taking-up circulated in this mode
The last n pixel of the first row and being deposited into for order after single treatment move horizontally the follow-up caching of data cache module 5.1
N pixel and it is stored in address, before the first row before further taking out after single treatment and moves horizontally data cache module 5.1
In follow-up buffer address, when moving horizontally the deposit data line of data cache module 5.1, then the row data are then horizontal shiftings
The pixel arrangement of motion video, the image pixel after above-mentioned processing is moved horizontally is carried out to every row pixel.
The step 2 is carried out after the step 103, step 2 concretely comprises the following steps：When first two row of piece image moves picture
According to after being cached to and moving horizontally data cache module 5.1, image level moves control module 9 and produced according to image sequential prime number
Image clock signal controlled level moving image data output module 6 moves horizontally image by what is cached caused by module 10
Data output feedwater translation motion video generation module 7, moves horizontally the removal of image generating module 7 and moves horizontally in view data
Relative delay and shake, move horizontally view data and image clock signal synchronously aligns, so as to produce the image moved horizontally
Signal, and it is sent into image synchronization buffer module 8.
In the step 103 of above-mentioned technical proposal, before operation is moved horizontally, the number of pels per line of original image according to by according to
In secondary order deposit raw image data cache module 2, after operation startup is moved horizontally, image level mobile module 4.1
Control module 3, which is read, according to translational speed (moving pixel) control raw image data reads raw image data cache module 2
Pixel, the image level movement notification image of control module 9 moves horizontally the number of pixels that module 4.1 moves every time, and starts
Image level mobile module 4.1 works, and image level mobile module 4.1 is then according to the method for operation moved horizontally as previously described
Control raw image data reads control module 3 and reads corresponding pixel data from raw image data cache module 2.
In the step 2 of above-mentioned technical proposal, to avoid having the phenomenon of splashette in the switching from rest image to mobile image,
Image level movement control module 9 can wait a frame of current quiet image after the output of image generating module 7 is moved horizontally,
Control moves horizontally image generating module 7 and is switched under the operation of output level mobile image when next new frame starts, same to time control
System moves horizontally view data output module 6 and moves horizontally view data output by what is cached.Specific operation process is：Work as water
Translate motion video generation module 7 and controlled output mobile picture by image level movement control module 9 when a new frame starts
After order, then the RGB image clock signal that is sent according to image sequence generation module 10, in the video data useful signal of every row
During starting, the mobile image number of the read level mobile data cache module 5.1 of controlled level moving image data output module 6
According to now, moving horizontally view data output module 6 then by moving horizontally image generating module 7 in RGB image clock signal
Control is lower alternately to read the data for being cached to and moving horizontally 5.1 two sub- buffers of data cache module, moves horizontally image production
When raw module 7 obtains the moving picture data of each row successively, then remove both relative delay and shake, it is ensured that data and RGB
Image clock signal synchronously aligns, and so as to produce the RGB image signal moved horizontally, and gives image synchronization buffer module 8.
In above-mentioned technical proposal, due to the visual persistence phenomenon of human eye, the principle that moving image is shown on module is every
Moving horizontally after image shows some frame numbers for secondary fixation shows that fixes next time moves horizontally image again, and such human eye is taken a fancy to
It is coherent movement to remove image, so, the timing of picture moving speed one (i.e. pixel movement interval holding is constant), every time mobile figure
As showing that frame number is more, similarly, when each mobile image shows that frame number is constant, each faster (i.e. pixel of picture moving speed
Mobile interval becomes big), then human eye looks the faster of image movement, on the contrary then slower.Above it is stated that picture moving speed
Operation, illustrate the operation of picture moving frame number now：After upper-layer configured picture moves frame number every time, opened when moving horizontally picture
When beginning is exported by moving horizontally image generating module 7, image level movement control module 9 monitors simultaneously is moving horizontally image production
The output frame number of each moving image in raw module 7, when image level movement control module 9 detects current moving image
When the frame number of output is not reaching to configured frame number, then image level movement control module 9 controls image to move horizontally module
4.1 still produce present level moving image, i.e. the original position of the circulation read operation of original image pixels is constant, so then protects
Current moving image has been held to show, every time after the frame image data for moving horizontally image generating module 7 all exports, image
Control module 9 is moved horizontally to control image memory interface 1 to read the row view data of beginning two of original image again and cache
Into raw image data cache module 2, and control image to move horizontally module 4.1 and carry out same moving operation, from image
Memory interface 1 to being all then constantly to cache next line when a line operates during moving horizontally data cache module 5.1, when
Image level movement control module 9 detects that the current moving image output frame number moved horizontally in image generating module 7 reaches
When configuring frame number (now the data of present frame have all passed), then image level movement control module 9 equally controls image to deposit
Store up interface 1 and input original image row data, and control image to move horizontally the operation that module 4.1 carries out next moving image, i.e.,
Reading is started the cycle over from next mobile pixel, the interval of now next mobile pixel (such as from pixel 1, is spaced 2 pictures
Element, circulating and read since pixel 3) i.e. translational speed moves control module 9 also by image level and controls image level to move
Dynamic model block 4.1 and produce new moving image data.So as to realize the display of new moving image frame.
In above-mentioned technical proposal, when image level movement control module 9 detects that to move horizontally image generating module 7 inner each
When the mobile totalframes of individual moving image output or movement reach totalframes or the total time that upper strata is configured total time, wait last
After the completion of one frame mobile image has exported, " whether can show that the image of last transportable frame still returns further according to set by upper strata
Echo show static original image " command operation, when to show last transportable frame, then image level movement control module 9
Such as keep moving picture data constant, when to return to display original image, then stop the module of related moving operation, and control
Move horizontally image generating module 7 and original image number is directly read under RGB clock signal synchronizations by image memory interface 1
According to so as to export original static stationary data.
In above-mentioned technical proposal, no matter original static stationary image or move horizontally image be output to move horizontally image output
During interface 11, output video standard that image output interface 11 is configured according to the upper strata of image memory interface 1 is moved horizontally (such as
LVDS low-voltage differential signals, MIPI movement Industry Processor Interfaces signal, DP high-definition digitals display interface signals, V-By-One
Video standard etc.) and various video standards configured transmission (such as LVDS standards VESA/JEIDA coding, transmission Link links
Number；The transmission Lane port numbers of MIPI standards, Video/Command patterns；DP1.1/1.2, driving preemphasis, the V- of DP standards
