Embodiment
For ease of understanding the present invention, will combine accompanying drawing to set forth in detail below.
Please refer to Fig. 1, the present invention proposes a kind of large-screen splicing wall synchronous display method, comprise step:
101, input signal is carried out piecemeal;
Input signal is carried out piecemeal, and adjacent piece contains the overlapping region.
102, piecemeal is carried out image data;
Overlapping region data to each piece are carried out pixel sampling respectively.
103, selected reference piece;
With one of them piecemeal as reference block.
104, whether detection adjacent block and reference block be synchronous;
The detection reference piece is adjacent the pixel difference of present frame of identical overlapping region of piece whether more than or equal to predetermined value, if then carry out step 105; If not, then carry out step 107.
105, adjust synchronously;
Obtain this adjacent block, with the present frame position of the identical overlapping region of reference block before and after the pixel of the first predetermined frame number as first reference pixel; Pixel with present frame this identical overlapping region of adjacent block this first reference pixel, reference block is compared; When the pixel difference of the present frame of the pixel of first predetermined frame, reference block during, first predetermined frame is adjusted into the present frame of this adjacent block less than predetermined value.
106, selected reference piece again;
The piece of just accomplishing frame synchronization is returned step 104 as new reference block.
107, whether other all piecemeals and reference block be synchronous;
Judge whether other all piecemeals and reference block be synchronous, if then carry out 108 steps; If not, then return 104 steps.
108, output divides block signal synchronously.
The present invention proposes the synchronous method of a kind of large screen display, earlier input signal is contained the piecemeal of overlapping region; Gather the content of overlapping region; Carry out interframe content mode of comparing, utilize the identical overlapping region of adjacent block to carry out content relatively; When the content of consecutive frame is asynchronous with selected reference frame, before and after consecutive frame present frame position, search the frame identical in the content of certain frame number with the reference frame content; Be that the present frame of consecutive frame shows with this framing control then; Automatically each the road video content that shows has synchronously solved when input signal itself is asynchronous, and picture shows nonsynchronous problem, promotes user experience.
When carrying out the piecemeal of input signal, carry out according to user's requirement; User's requirement, for example: per 2 combinations show that subelement shows same shunting sign, perhaps each combination shows that subelement shows a shunting sign.
As a kind of specific embodiment, please refer to Fig. 2, each display unit of the combination of 2*2 shows one road unlike signal; A kind of signal block division method, for A piece and B piece, its overlapping region scope is: the zone that A1A2B1B3 representes; For A piece and C piece, its overlapping region scope is: the zone that A3A4B2B4 representes; For B piece and D piece, its overlapping region scope is: the zone that B2B4A7A8 representes; For C piece and D piece, its overlapping region scope is: the zone that B1B3A5A6 representes.
When carrying out the pixel sampling of overlapping region, use the sampling sample mode, for example minor increment sampling sample mode can improve the efficient of synchronous demonstration.
When carrying out the choosing of reference block for the first time, can choose any in the demonstration subelement of combination; When the demonstration subelement number of combination is a lot; Can choose one of them that be positioned at the combination centre position and show that subelement is as selected for the first time reference block; Can accomplish the whether synchronous detection of all piecemeals so faster, save time, raise the efficiency.
For step 104, when carrying out synchronous detection, a kind of preferred implementation is: be example with Fig. 2, the selected reference piece is the A piece; Reference block is adjacent piece B piece when carrying out synchronous detection, establish on the A piece pixel with one of them position of present frame of the overlapping region of B piece and be Ya (i, j); On the B piece with the pixel of one of them position of present frame of the overlapping region of A piece be Yb (i, j); Its pixel difference is:
D(i，j)＝Yb(i，j)-Ya(i，j)；
(i during j) more than or equal to predefined value D0, is judged to be A, B piece present frame is asynchronous as D; (i during j) less than predefined value D0, is judged to be A, B piece present frame is synchronous as D; Simultaneously, in order to improve the accuracy of synchronous detection, can be with adding up with all pixel difference of the present frame same position of the overlapping region of B piece on the A piece; If its pixel difference accumulated value is then judged asynchronous more than or equal to predetermined value (being different from D0); If its pixel difference accumulated value less than predetermined value, is then judged synchronously.
To above-mentioned 105 steps, when in the pixel of the predetermined frame number of adjacent block first, when still not finding, on the original basis, further enlarge the participation frame number relatively of adjacent block with the synchronous frame of the present frame of reference block, improve synchronous probability:
When the pixel difference of the present frame of the pixel of first predetermined frame and reference block during more than or equal to predetermined value, the pixel of obtaining the second predetermined frame number before and after this adjacent block present frame position is as second reference pixel;
Second reference pixel is compared with the pixel with present frame this identical overlapping region of adjacent block reference block successively; If the pixel difference of the pixel of second predetermined frame and the present frame of reference block during less than the value of being scheduled to, is adjusted into second predetermined frame present frame of this adjacent block.
As a kind of specific embodiment, be example with A piece among Fig. 2 and B piece, setting with the A piece is reference block, the A piece is asynchronous with the B piece; Concrete adjustment process please refer to Fig. 3; The present frame of A piece is F1; The present frame of B piece is F2-3; With front and back 2 frames (the first predetermined frame number) of the present frame of B piece respectively with the present frame of A piece relatively, still not have to find and the synchronous frame F2 of present frame of A piece; So with 4 frames before and after the present frame of B piece (the second predetermined frame number) respectively with the present frame of A piece relatively; Since front and back 2 frames of the present frame of B piece with the present frame of A piece mistake relatively; So no longer compare, only carry out front and back the 3rd, 4 frames and the comparison of A piece present frame of the present frame of B piece; Present frame through preceding the 3rd frame F2 of present frame that relatively finds the B piece and A piece is synchronous, so the 3rd frame before the present frame of B piece (second predetermined frame) F2 is adjusted into the present frame of B piece.
The first predetermined frame number, first predetermined frame, the second predetermined frame number are different with second predetermined frame, and the first predetermined frame number and the second predetermined frame number are the quantity of frame, and first predetermined frame and second predetermined frame are concrete frames; Simultaneously, the scope of the second predetermined frame number is greater than the first predetermined frame number.
To the foregoing description, the pixel of the second predetermined frame number is compared with the pixel with present frame this identical overlapping region of adjacent block reference block successively, still do not find the frame synchronous with the reference block present frame, then system reports an error, and stops synchronous adjustment.
Introduce device of the present invention below, please refer to Fig. 4, a kind of large-screen splicing wall synchronous display apparatus comprises:
