Pixel, mobile 9 notification image of control module of image moves left and right the number of pixels that module 4.1 moves every time, and starts image
The work of module 4.1 is moved left and right, image moves left and right module 4.1 then according to the method for operation control moved horizontally as previously described
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 that splashette in the switching from static image to mobile image,
The mobile control module 9 of image can wait a frame of current quiet image after the output of mobile image generation module 7, in next new frame
The operation that mobile image generation module 7 is switched to output mobile image (including horizontal, vertical, oblique line is mobile) is controlled when beginning
Under, while controlling moving image data output module 6 and exporting the moving image data cached.Specific operation process is: when
After mobile image generation module 7 is controlled output mobile picture commands by the mobile control module 9 of image when a new frame starts,
The RGB image clock signal then issued according to image sequence generation module 10, in the video data useful signal starting of every row,
Control moving image data output module 6 reads the moving image data for moving left and right data cache module 5.1, at this point, mobile
Image data output module 6 is then alternately read under the control of RGB image clock signal by mobile image generation module 7 and is cached to
The data of 5.1 two sub- buffers of data cache module are moved left and right, mobile image generation module 7 successively obtains the movement of each row
When picture data, then remove the relative delay and shake of the two, it is ensured that data alignment synchronous with RGB image clock signal, thus
The RGB image signal moved horizontally is generated, and gives image synchronization buffer module 8.
In above-mentioned technical proposal, due to the visual persistence phenomenon of human eye, show that the principle of moving image is every in mould group
The mobile image of secondary fixation shows next time fixed mobile image after showing several frame numbers again, and such human eye seems that image is
Coherent movement, in this way, one timing of picture moving speed (i.e. the mobile interval holding of pixel is constant), each mobile image show frame
Number is more, similarly, when each mobile image shows that frame number is constant, faster (the i.e. mobile interval of pixel of each picture moving speed
Become larger), then human eye seems the faster of image movement, on the contrary then slower.Above it is stated that the operation of picture moving speed, now
Illustrate the operation of picture moving frame number: after upper-layer configured picture moves frame number every time, starting when moving horizontally picture by moving
When image generating module 7 exports, each shifting of the mobile monitoring simultaneously of control module 9 of image in mobile image generation module 7
The output frame number in animation face is matched when the mobile control module 9 of image detects that the frame number of current moving image output does not reach
When the frame number set, then the mobile control of control module 9 image of image moves left and right module 4.1 and still generates current moving image, i.e.,
The initial position of the circulation read operation of original image pixels is constant, then maintains current moving image in this way and shows, every time when shifting
For one frame image data of motion video generation module 7 all after output, the mobile control module 9 of image controls image memory interface 1 again
It re-reads the two row image data of beginning of original image and is cached in raw image data cache module 2, and control image
It moves left and right module 4.1 and carries out same moving operation, from image memory interface 1 to moving left and right data cache module 5.1
It is all then constantly to cache next line when a line operation in the process, when the mobile control module 9 of image detects that mobile image generates
When current moving image output frame number in module 7 reaches configuration frame number (data of present frame have all passed at this time), then scheme
As mobile control module 9 equally control image memory interface 1 input original image row data, and controls image and move left and right module
4.1 carry out the operation of next moving image, i.e., start the cycle over reading from next mobile pixel, mobile pixel next at this time
Interval (such as from pixel 1, being spaced 2 pixels, circulation is read since pixel 3) i.e. movement speed is controlled also by image is mobile
Module 9 moves left and right module 4.1 controlling image and generates new moving image data.To realize new moving image frame
Display.
In above-mentioned technical proposal, when the mobile control module 9 of image detects the inner each mobile picture of mobile image generation module 7
When the mobile totalframes of face output or movement reach the totalframes or total time that upper layer is configured total time, wait last frames mobile
After the completion of image has exported, can further according to set by upper layer " whether show the image of last transportable frame still returns show it is quiet
The command operation of original image only ", when to show last transportable frame, then the mobile control module 9 of image is as kept mobile picture
Face data is constant, when to return to display original image, then stops the module of related moving operation, and controls mobile image generation
Module 7 directly synchronizes lower reading raw image data in RGB clock signal by image memory interface 1, to export original
Data-at-rest.
In above-mentioned technical proposal, no matter original static stationary image or each mobile image are output to mobile image output interface
When 11, output video standard (the low electricity of such as LVDS that mobile image output interface 11 is configured according to the upper layer of image memory interface 1
Pressure difference sub-signal, MIPI mobile industry processor interface signal, DP high-definition digital display interface signals, V-By-One video standard
Deng) and various video standards configured transmission (such as LVDS standard VESA/JEIDA coding, transmission Link number of links；MIPI mark
The transmission Lane port number of standard, Video/Command mode；DP1.1/1.2, driving preemphasis, the V-By-One mark of DP standard
Quasi- data transmission rate, data array etc.) it is converted into required corresponding vision signal, and synchronism output is carried out, thus
Can in mould group simultaneously three kinds of mobile images of simultaneous display.
In the step 1 of above-mentioned technical proposal, when image mobile module 4 carries out vertically moving processing, carry out as follows
Step process, as described in Fig. 4 and Fig. 5:
Step 111: when the configuration of high-level interface module 12 vertically moves parameter, vertically moving parameter includes the side of vertically moving
To, movement speed, mobile image stop frame number (traveling time, mobile image totalframes be ginseng common to three kinds of moving images
Number), the above-mentioned parameter informing that vertically moves is moved up and down data cache module 5.2 by image memory interface 1, and it is slow to move up and down data
Storing module 5.2 then compiles mobile row shown by every a line according to vertically move direction, the movement speed that vertically move in parameter
Number by the mobile control module 9 of image moving condition signal notification image, the mobile control module 9 of image controls image memory interface
1 sequence reads corresponding row data and is cached in raw image data cache module 2 (is only stored in several rows currently needed in this way
Image, rather than all row images reduce the mobile complexity of data and error can to reduce required spatial cache
Energy property, and improve the reliability of mobile image), the different initial data input of mobile 9 pairs of the control module of image synchronizes
And coordinated control, it will lead to operation interlocking and conflict to ensure image reading not；
Step 112: after the completion of the caching of raw image data cache module 2, the mobile control module 9 of image is controlled on image
Lower mobile module 4.2 starts the read operation that raw image data reads control module 3；
When image move up and down module 4.2 control image vertically move, and vertically move speed be 1 pixel when, image
Module 4.2 is moved up and down to first pass through the pixel of the raw image data reading taking-up last line of control module 3 and be stored in up and down
In mobile data cache module 5.2, after further taking out the pixel of the first row and being stored in and move up and down data cache module 5.2
The pixel for last line that once treated in continuous buffer address, before the taking-up recycled in this mode is simultaneously stored in
In the subsequent buffer address of lower mobile data cache module 5.2, then the pixel of the first row after single treatment is simultaneously before it is removed
It is stored in and is moved up and down in the subsequent buffer address of data cache module 5.2, the image pixel after being vertically moved.
In the step 112, vertically moved when image moves up and down the control image of module 4.2, and vertically moving speed is n
A pixel, and when n > 1, image, which moves up and down module 4.2 and first passes through raw image data and read control module 3, takes out last n row
Pixel and being stored in move up and down in data cache module 5.2, the pixel of n row and being stored in moves up and down before further taking out
In the subsequent buffer address of data cache module 5.2, the picture of primary treated last n row before the taking-up recycled in this mode
Element is simultaneously stored in and is moved up and down in the subsequent buffer address of data cache module 5.2, then before it is removed after single treatment
The pixel and being stored in of preceding n row move up and down in the subsequent buffer address of data cache module 5.2, vertically moved
Image pixel afterwards.
The step 2, the specific steps of step 2 are carried out after the step 112 are as follows: the mobile control module 9 of image is according to figure

Oblique line mobile module 4.3 takes out the pixel of last n row by raw image data reading control module 3 and is stored in oblique line movement
In data cache module 5.3, the pixel of n row and to be stored in oblique line mobile data cache module 5.3 subsequent before further taking out
In buffer address；
Then image oblique line mobile module 4.3 carries out moving left and right operation, and left and right in the result of vertical movement operation
Movement speed is n pixel, and image oblique line mobile module 4.3 first takes out in oblique line mobile data cache module 5.3 and vertically moves
The pixel of taking-up is simultaneously stored in oblique line mobile data cache module by the last n pixel of the first row in operating result data
In 5.3 new spatial caches, the preceding n in oblique line mobile data cache module 5.3 in vertical movement operation result data is further taken out
A pixel, and the pixel of taking-up is stored in subsequent caching in the new spatial cache of oblique line mobile data cache module 5.3
In address.
The step 2, the specific steps of step 2 are carried out after the step 122 are as follows: the mobile control module 9 of image is according to figure
The mobile figure that the control moving image data output module 6 of the image clock signal as caused by sequence generation module 10 will be cached

Shake, moving image data alignment synchronous with image clock signal, to generate the mobile picture signal of oblique line, and is sent into image
Sync buffering module 8 exports.
In above-mentioned technical proposal, since the present invention is to export and show simultaneously horizontal, vertical, oblique line mobile image,
It is carried out simultaneously in the operation of these three mobile images, but the behaviour since three kinds of implementations are different, between them
It is also different to make the time, although so that mobile image generation module 7 can export three kinds of images simultaneously, not synchronism output
(i.e. three's image output has delay to each other), thus image synchronization buffer module 8 is needed to be synchronized output.Image is same
Step buffer module 8 inputs after three's picture signal and caches multi-line images as unit of image line, at least to cache a line, this takes
It is later referring to the image letter for exporting caching simultaneously with the image timing of maximum delay certainly in the different operation characteristics for realizing device
Number, such three kinds of moving images realize synchronism output simultaneously.
