Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects be described in detail in claims, the disclosure.
Fig. 1 is a kind of flow chart of image data recording method shown according to an exemplary embodiment, the present embodiment with
The image data recording method is applied to illustrate in terminal.The image data recording method may include following several steps
It is rapid:
In a step 101, the display demand of image is obtained, display demand includes picture quality needed for image or response speed
Degree.
In a step 102, data compression ratio corresponding to display demand is determined.
In step 103, the Image Data Compression of the image is stored to the RAM of driving chip according to data compression ratio
In.
In conclusion method provided in this embodiment determines that the display demand institute is right by obtaining the display demand of image
Then the data compression ratio answered stores the Image Data Compression of the image into the RAM of driving chip according to data compression ratio.
Compression storage, the larger problem of limitation can only be done according to fixed compression ratio in the related technology by solving；Having reached can root
Data compression ratio is adjusted flexibly according to the display demand of image, and then adapts to the effect of various scenes.
Fig. 2 is a kind of flow chart of image data recording method shown according to an exemplary embodiment, the present embodiment with
The image data recording method is applied to illustrate in terminal.The image data recording method may include following several steps
It is rapid:
In step 201, the display demand of image is obtained, display demand includes picture quality needed for image or response speed
Degree.
When application program in terminal needs to show image, the image data of image can be passed to system by application program
Driving chip is called by system end, and then image is shown by driving chip driving display screen in end.Wherein, application program can be
Terminal downloads and the application program installed, or the included application program of system in terminal.System end in terminal refers to
For controlling the GPU (Graphics Processing Unit, graphics processor) of driving chip.
When application transfer image data to system end, can the simultaneous transmission image data display demand to system
End.System end can get the display demand accordingly.
For example, in video playing application program, when user triggers video a certain with ' high definition ' mode playback, the video
' high definition ' can also be played while transmitting video data to the system end of the video and be transferred to system by play-back application
End.Correspondingly, system end is available to the display demand for being somebody's turn to do ' high definition '.Similar, if user's triggering is broadcast with ' smoothness ' mode
When putting, the available display demand to ' smoothness ' of system end.
It should be added that only being lifted in the present embodiment with display demand includes picture quality or response speed
Example explanation, optionally, display demand can also include other content, and the present embodiment is to this and is not construed as limiting.
In step 202, according to the corresponding relationship between display demand and data compression ratio, corresponding to query display demand
Data compression ratio.
Terminal prestores the corresponding relationship between display demand and data compression ratio.Wherein, which includes: image
Negative correlativing relation, response speed between quality and data compression ratio and the positive correlation between data compression ratio or simultaneously
Including both above-mentioned.And the data compression ratio in the present embodiment is less than or equal to data compression corresponding to the RAM of driving chip
Than.For example, being that 1/2RAM comes for example, the data compression ratio in the present embodiment is less than or equal to the RAM of driving chip
1/2。
Optionally, this step may include:
(1) if display demand includes picture quality, according to the negative correlativing relation between picture quality and data compression ratio,
Data compression ratio corresponding to query image quality.
The data compression ratio that image data uses is bigger, and image fault rate is higher, the image matter of the image finally shown
It is also poorer to measure.So the corresponding relationship between the picture quality prestored in terminal and data compression ratio can close to be negatively correlated
System.
For example, please referring to following table, picture quality is ' high definition ', and data compression ratio 1/3, picture quality is ' ultra high-definition ',
Data compression ratio is 1/2.
| Picture quality | Data compression ratio |
| High definition | 1/3 |
| Ultra high-definition | 1/2 |
After terminal gets display demand by system end, terminal can inquire above-mentioned corresponding pass by system end
System, and then obtain data compression ratio corresponding with picture quality.For example, come using the picture quality of needs as high definition for example,
The data compression ratio that system end is got is 1/3.
(2) if display demand includes response speed, the positive correlation between speed and data compression ratio according to response,
Data compression ratio corresponding to inquiry response speed.
For different objects, response speed it is customized not identical, such as when show object be a picture when, the response speed
Degree refers to the display speed of picture, and when showing object is one section of video, which refers to the fluency of video playing.
In actual implementation, data compression ratio is bigger, and compressed data with regard to smaller, also get over accordingly by data transmission bauds
Fastly, so corresponding relationship between the response speed that terminal prestores in the present embodiment and data compression ratio, can close to be positively correlated
System.
In step 203, image data is compared according to data compression to be compressed.
In step 204, compressed image data is stored into RAM corresponding to data compression ratio.
Optionally, this step may include:
(1) compressed image data is sent to driving chip by system end.
Compressed image data can be passed through MIPI (Mobile Industry Processor by system end
Interface, mobile industry processor interface) it is transmitted to driving chip.Optionally, system end is transmitting compressed picture number
According to while, data compression ratio can be transmitted to driving chip together.
(2) driving chip receives the compressed image data that system end is sent, and compressed image data is stored
Into the RAM of driving chip corresponding to data compression ratio.
After driving chip receives compressed image data, compressed image data that driving chip will receive
It stores into the RAM of driving chip.
Optionally, if system end sends data compression ratio together, driving chip is storing compressed image data extremely
It when RAM, is storing to memory space corresponding to data compression ratio, driving chip is the picture number that can determine that present image
It is finished according to storage.For example, being 1/3 with data compression ratio and RAM is that 1/2RAM comes for example, being filled with 1/ in driving chip
2RAM 2/3 when, driving chip is you can learn that the image data storage of present image finishes.
Optionally, when driving chip stores compressed image data, driving chip can store compressed image
Fixation position of the data into RAM.For example, being all to be stored since the initial position of RAM, the present embodiment does not limit this
It is fixed.
In step 205, the compressed image data stored in the RAM of driving chip is read.
In step 206, the compressed image data read is compared according to data compression to unzip it.
In step 207, image displaying is carried out according to the image data after decompression.
In conclusion method provided in this embodiment determines that the display demand institute is right by obtaining the display demand of image
Then the data compression ratio answered stores the Image Data Compression of the image into the RAM of driving chip according to data compression ratio.
