Abstract
The invention provides a kind of Memory Optimize Method of video cartoon picture storage, comprise the following steps：Video cartoon picture is extracted, based on the video cartoon picture, each frame PNG pictures in the video cartoon picture are obtained；Based on the PNG pictures, JPG pictures are converted into；Based on the JPG pictures, the reproduction of video cartoon picture is converted into.A kind of Memory Optimize Method of video cartoon picture storage of the present invention, after video cartoon picture is extracted, PNG pictures are converted into JPG pictures by Alpha channel datas, then Alpha port numbers data are deleted, internal memory is consumed so as to reduce video cartoon picture processing, to reach the purpose of memory optimization, the internal memory of picture during reduction operation.
Description
Technical field
The present invention relates to field of Computer Graphics, especially a kind of Memory Optimize Method of video cartoon picture storage.
Background technology
Currently, the scope that various wearable virtual reality electronic equipments are used in everybody life is quite varied.With
Multimedia technology is continued to develop, by a variety of acoustooptical effects that it possesses, in above-mentioned wearable virtual reality electronic equipment
The upper various multimedia messages of broadcasting are that the institute of users is common desired.
However, animation file is general all larger, in order to adapt to be played on wearable virtual reality electronic equipment, generally need
Processing is compressed to it.Existing cartoon compressing method is divided into two classes：
1st, each content frame is compressed respectively, then decompresses and show frame by frame when playing.Such method realization is simple, but
Compression ratio is often very undesirable；
2nd, animated content is considered as an entirety, color signal is separated with luminance signal and carrier chrominance signal, then damage pressure
Contracting, such as MPEG., its advantage is that compression ratio is high, but operand is big.Can not smooth playing in the equipment using low speed chip.Greatly
Most such compression algorithms are based on 24 RGB color domain spaces.For the LCD only 12bit color depths of current a large amount of handheld devices,
The dual waste of space and time are caused in data transfer and decompression operation.
And on existing wearable virtual reality electronic equipment, the hardware condition provided also varies.Most
When playing multimedia messages, particularly animation file on several wearable virtual reality electronic equipment electronic equipments, it is easy to make
Into wearable virtual reality electronic equipment low memory, and cause the discontinuous problem of video playback.
The content of the invention
The present invention provides a kind of Memory Optimize Method of video cartoon picture storage, to solve existing wearable virtual reality
Animated video stored memory consumes excessive technical problem on electronic equipment.
According to an aspect of the invention, there is provided a kind of Memory Optimize Method of video cartoon picture storage, including with
Lower step：
Step S1. extracts video cartoon picture, based on the video cartoon picture, obtains each in the video cartoon picture
Frame PNG pictures；
Step S2. is based on the PNG pictures, is converted into JPG pictures；
Step S3. is based on the JPG pictures, is converted into the reproduction of video cartoon picture.
On the basis of such scheme preferably, the step S1 includes in detail：
Step S1.1 is based on video cartoon picture, obtains each frame PNG pictures in the memory block of the video cartoon picture
File is described with animation；Wherein, the animation describes file and describes the store path of picture and each frame picture of the animation
Pictorial information cited in face；
Step S1.2 describes file based on the animation, is filtered out from acquired picture not by the figure cited in the animation
Piece, obtains picture redundancy collection；
Step S1.3 is in the corresponding memory block of the resource store path, and the picture that will be contained in the picture redundancy concentration is deleted
Remove.
On the basis of such scheme preferably, the step S2 includes in detail：
Step S2.1 is based on each frame PNG pictures, to extract the Alpha channel datas for obtaining each frame PNG pictures；
The Alpha channel datas of each frame PNG pictures are converted into JPG pictures by step S2.2.
On the basis of such scheme preferably, also include between the step S2 and S3：
By the video cartoon picture compression obtained by the step S1, and by the Alpha passages in the step S2.1
Data are rejected.
A kind of Memory Optimize Method of video cartoon picture storage of the present invention, after video cartoon picture is extracted,
PNG pictures are converted into JPG pictures by Alpha channel datas, then Alpha port numbers data are deleted, regarded so as to reduce
The processing of frequency motion picture consumes internal memory, to reach the purpose of memory optimization, the internal memory of picture during reduction operation.
Brief description of the drawings
Fig. 1 is the flow chart of the model animation interlock method based on Unity3D of the present invention.
