Specific embodiment
Embodiments of the present invention are described below in detail, the embodiment of the embodiment is shown in the accompanying drawings, wherein
Same or similar label indicates same or similar element or element with the same or similar functions from beginning to end.Lead to below
It crosses the embodiment being described with reference to the drawings to be exemplary, for explaining only the invention, and should not be understood as to limit of the invention
System.
In embodiments of the present invention, sequence frame includes multiframe picture, and any animation may be implemented in play sequence frame, including
Complicated and simple animation.Referring to Fig. 1, the animation play processing method based on sequence frame of embodiment of the present invention include with
Lower step:
S10: every frame picture is respectively classified into the identical multiple sub-pictures of quantity；
S20: the similarity of identical two sub-pictures of two frame Pictures locations of front and back is calculated；
S30: judge whether the sub-pictures of posterior picture need to refresh and store judging result according to similarity；With
S40: refresh the sub-pictures for needing to refresh according to judging result in play sequence frame.
Every frame picture in sequence frame is divided into multiple sub-pictures by the animation play processing method of embodiment of the present invention,
Then the similarity for comparing the sub-pictures of two frame pictures of front and back, the sub-pictures that needs refresh are determined according to similarity, thus
It reduces the refreshing frequency of picture and refreshes area, improve frame per second, guarantee that animation play is smooth.
In step slo, referring to Fig. 2, being respectively split every frame picture identical every frame picture is divided into quantity
Sub-pictures.In the figure 2 example, the cutting procedure of three frame picture A, B and C is illustrated only, picture A and picture B are front and backs
Two frame pictures, picture B and picture C are two frame pictures of front and back, and every frame picture is divided into 4 sub-pictures merely to example is said
It is bright, in actual embodiment, it can be set as needed the quantity of sub-pictures.
In step S20, referring to Fig. 3, calculating the similarity of identical two sub-pictures of two frame Pictures locations of front and back.
In the example of fig. 3, sub-pictures A1 and sub-pictures B1 is two frame picture A of front and back, identical two sub-pictures of B location, subgraph
Piece B1 and sub-pictures C1 is two frame picture B of front and back, identical two sub-pictures of location of C.The relationship of the sub-pictures of other numbers
So analogize.
In step s 30, judged according to the similarity of identical two sub-pictures of two frame Pictures locations of front and back posterior
Whether the sub-pictures of picture need to refresh and store judging result, such as are judged according to the similarity of sub-pictures A1 and sub-pictures B1
Whether sub-pictures B1, which needs, is refreshed, if sub-pictures B1 needs to refresh, then judging result indicates that sub-pictures B1 needs to refresh.At this
In the embodiment of invention, the similarity of identical two sub-pictures of two frame Pictures locations of front and back is more than 95% (> 95%) nothing
The sub-pictures of posterior picture need to be refreshed, the similarity of identical two sub-pictures of two frame Pictures locations of front and back is no more than 95%
(=< 95%) need to refresh the sub-pictures of posterior picture.In the example of fig. 3, the sub-pictures that solid box indicates do not need to brush
Newly, the sub-pictures that dotted line frame indicates need to refresh.In embodiments of the present invention, all sub-pictures of first frame picture are all arranged
To need to refresh, i.e., in the example of fig. 3, sub-pictures A1, A2, A3 and A4 are required to refresh.
In step s 40, only refresh the sub-pictures for needing to refresh in play sequence frame.In this way, every frame picture is divided into
Multiple sub-pictures and the sub-pictures that needs refresh are determined according to the similarity of the identical sub-pictures of two frame Pictures locations of front and back,
The refreshing frequency of picture can be reduced and refresh area, improve frame per second to guarantee animation play smoothness.
Further, step S10 to step S30 is completed before sequence frame broadcasting, is not needed again in play sequence frame
The calculating of similarity is carried out, the sub-pictures for needing to refresh need to be only refreshed, to avoid occupying processor (such as CPU) resource, is made
It is more efficient to draw play handling method.
In some embodiments, the step of calculating the similarity of identical two sub-pictures of two frame Pictures locations of front and back
It include: the similarity that identical two sub-pictures of two frame Pictures locations of front and back are calculated using hash algorithm.

Algorithm mature and reliable.In the example of fig. 3, it is first utilized respectively hash algorithm and calculates sub-pictures A1 and sub-pictures B1, sub-pictures A2
With the similarity of sub-pictures B2, sub-pictures A3 and sub-pictures B3 and sub-pictures A4 and sub-pictures B4, subgraph is judged according to similarity
Whether piece B1, sub-pictures B2, sub-pictures B3 and sub-pictures B4 need to refresh and store judging result；Then it is utilized respectively Hash again
Algorithm calculate sub-pictures B1 and sub-pictures C1, sub-pictures B2 and sub-pictures C2, sub-pictures B3 and sub-pictures C3 and sub-pictures B4 and
The similarity of sub-pictures C4 judges whether sub-pictures C1, sub-pictures C2, sub-pictures C3 and sub-pictures C4 need to brush according to similarity
Newly and store judging result.
Referring to Fig. 4, in some embodiments, two frame Pictures locations identical two of front and back are calculated using hash algorithm
The similarities of a sub-pictures the following steps are included:
S22: all pixels point of identical two sub-pictures of two frame Pictures locations of front and back is obtained；
S24: the similarity of each pixel of two sub-pictures is calculated separately；With
S26: the average value of the similarity of all pixels point and the similarity as two sub-pictures are calculated.
In this way, determining the similarity of two sub-pictures by the average value of the similarity of all pixels point of two sub-pictures.
Specifically, the similarity that pixel is calculated using hash algorithm, the gray scale of each pixel is obtained by the rgb value of each pixel
Value compares the gray value of the pixel of two sub-pictures of two frame pictures of front and back to obtain the similar of the identical pixel in position
Then degree calculates the average value of the similarity of all pixels point and putting down the similarity of all pixels point in two sub-pictures again
Similarity of the mean value as two sub-pictures.
In some embodiments, animation play processing method is comprising steps of by the identical sub-pictures of multiframe Pictures location
It is stored in same file folder.
In this way, facilitating the similarity for calculating identical two sub-pictures of two frame Pictures locations of comparison front and back.It is appreciated that
After multiframe picture is divided into multiple sub-pictures, the identical sub-pictures of multiframe Pictures location are stored in after same file accompanies and be conducive to
It is continuous that calculating similarity is carried out to identical two sub-pictures of two frame Pictures locations of front and back more quickly.In the figure 2 example, sub
Picture A1, sub-pictures B1 and sub-pictures C1 are stored in same file folder, and sub-pictures A2, sub-pictures B2 and sub-pictures C2 are stored in
Same file folder, sub-pictures A3, sub-pictures B3 and sub-pictures C3 are stored in same file folder, sub-pictures A4, sub-pictures B4
Same file folder is stored in sub-pictures C4.These files can be located at the same memory or different memories.
