Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The process flow diagram of the disposal route of the picture a kind of in enormous quantities that reference Fig. 1, Fig. 1 provide for first embodiment of the invention, the method comprising the steps of:
S110: described picture, according to the resolution of picture, frequency of utilization and operation response speed requirement, is divided into pre-service picture and immediately processes picture by main frame;
Before graphical interfaces is applied to embedded device, can first design graphical interfaces design sketch, generate the graphical interfaces of embedded device according to this design sketch.In graphical interfaces design sketch, usually can include picture dissimilar in a large number, as background, static icon, motion picture etc., the resolution of each picture is different; In addition, the frequency of utilization of these pictures in graphical interfaces is also different, and as background, all will be loaded into background picture when each user starts embedded device, therefore the frequency of utilization of background picture is very high, and main frame generates frequency of utilization table according to the frequency of utilization of picture; Again, due to the restriction of embedded device hardware resource, embedded device treatable picture within a period of time is limited, in order to ensure that embedded device is loaded into the fluency of graphical interfaces, operation response speed for each picture also has different requirements, and main frame requires generating run response speed table according to operation response speed; More specifically, main frame is used for the storage chip storage space at display graphics interface and the capacity of memory source according to embedded device, simultaneously the high/low and operation response speed of resolution that is high/low according to frequency of utilization, picture require high/low between various combination, be pre-service picture by picture classification and immediately process picture, be specially:
1., when the resolution of described picture is high, frequency of utilization is low and operation response speed requires low, be described instant process picture by described picture classification.For this type of picture, consider from the angle of the storage space and internal memory of saving embedded device, main frame does not do the pre-service of Code or Bin aspect to it, and directly in subsequent diagram processing procedure, carries out hardware decode or software decode in the mode of the former figure of JPG, PNG or BMP to it.
Mentioned herein and the high/low of " frequency of utilization " be a relative concept, such as, on main interface, long-term rendering preferences icon, status bar icon etc. are using always, therefore frequency of utilization is the highest; And prompting motion picture during no signal just seldom uses, only just use when current input no signal, therefore frequency of utilization is very low.
Equally, the high/low of " the operation response speed requirement " herein mentioned also is a relative concept, the ICON that such as main interface just will show after ejecting at once, and its operation response speed requires very high, if its operation response speed is slow, master menu can be directly caused to eject slow; The operation response speed that the picture of non-signal prompt starts to show requires just not high, from system requirements display non-signal prompt picture, finally be revealed the length of time to this picture, the display effect impact for graphical interfaces is little, therefore the operation response speed of this picture requires very low.
2., when the resolution of described picture is high, frequency of utilization is high and operation response speed requires high, if the decoding of described picture support hardware, be then described instant process picture by described picture classification, otherwise be described pre-service picture by described picture classification; Such as background picture, the resolution of usual background picture is all higher, and all needs to be loaded into background picture when each startup embedded device, frequency of utilization is high, and in order to realize showing graphic interface glibly, requiring also high to operation response speed, being therefore necessary to carry out pre-service to it.
