Embodiment
In order to make purpose of the present invention, technical scheme and beneficial effect clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also Fig. 1, the realization flow of the method for in electronic equipment, handling picture that provides for the embodiment of the invention, it may further comprise the steps:
In step S101, after electronic equipment start, the memory device of described electronic equipment is scanned, find out picture greater than electronic equipment screen resolution;
In embodiments of the present invention, this electronic equipment can be advertisement machine or other electronic equipments that Shows Picture.
In step S102, described picture greater than electronic equipment screen resolution is narrowed down to the resolution of screen;
In step S103, picture after will dwindling and the picture that is less than or equal to electronic equipment screen resolution are decoded;
In step S104, the data stream that obtains after the decoding is stored in the described memory device;
In embodiments of the present invention, the form of the data stream that obtains after the decoding with file is stored in the described memory device.
In embodiments of the present invention, after step S104, further comprising the steps of:
When playing pictures, the data stream that obtaining decodes finishes, and be presented on the electronic equipment screen.
As one embodiment of the present invention, described during when playing pictures, the data stream that obtaining decodes finishes, and be presented at before the step on the electronic equipment screen, further comprising the steps of:
Decoded picture name is added in the decoded listed files.
Therefore, when playing pictures, skip decode procedure to original image, directly read the picture name in the described decoded listed files, and from described memory device, read the data stream of decoding finishing corresponding, and be presented on the electronic equipment screen with described picture name.
In embodiments of the present invention, the described account form that described picture greater than electronic equipment screen resolution is narrowed down to the resolution of screen is:
If greater than the picture width of electronic equipment screen resolution multiply by the screen resolution height again divided by the wide result of screen resolution less than described picture height greater than electronic equipment screen resolution, so, to equal screen resolution wide for the width of picture behind the convergent-divergent, and the height of picture equals described picture width greater than electronic equipment screen resolution and multiply by the screen resolution height again divided by the wide result of screen resolution behind the convergent-divergent.
If greater than the picture width of electronic equipment screen resolution multiply by the screen resolution height again divided by the wide result of screen resolution more than or equal to described picture height greater than electronic equipment screen resolution, so, the height of picture equals the screen resolution height behind the convergent-divergent, and the width of picture equals described picture height greater than electronic equipment screen resolution to multiply by screen resolution wide again divided by the high result of screen resolution behind the convergent-divergent.
For example, the common screen resolution of advertisement machine has following several: 640x480,800x600,1024x768,1280x720,1280x1024,1360x768,1600x1200,1920x1080.
Described picture greater than the advertisement machine screen resolution is being narrowed down in the step of screen output resolution ratio the size after adopting following formula to calculate picture to dwindle:
The former picture width of Width=
The former picture height of Height=
The ScreenWidth=screen resolution is wide
ScreenHeight=screen resolution height
The width of picture behind the out_width=convergent-divergent
The height of picture behind the out_height=convergent-divergent
If (Width*ScreenHeight/ScreenWidth)＜Height
Then
{
out_width＝ScreenWidth；
out_height＝Width*ScreenHeight/ScreenWidth；
}
Otherwise
{
out_width＝Height*ScreenWidth/ScreenHeight；
out_height＝ScreenHeight
}
Arriving former image zooming wide again is out_width, and height is that the picture of out_height gets final product.
Describe the implementation procedure of the method for picture of in advertisement machine, handling that the embodiment of the invention provides in detail below by son for example.
See also Fig. 2 for handling the process of picture, be achieved as follows:
In step S1, pre-service begins;
In step S2, obtain the screen output resolution ratio;
In step S3, detect whether memory device is arranged;
If in step S4, detect memory device, judge whether that then success reads file from this memory device; If do not detect memory device, it is rapid then to return previous step;
If in step S5, successfully from this memory device, read file, judge then whether the file that gets access to is picture file;
In step S6, if picture file, judge then whether this picture file joins " listed files of having decoded ";
If do not join in step S7 in " listed files of having decoded ", whether the resolution of then judging this picture is greater than the screen output resolution ratio;
If the resolution of judging this picture in step S8 then narrows down to the screen output resolution ratio with this picture, and decodes greater than the screen output resolution ratio; Otherwise, directly this picture is decoded;
The data stream that will obtain in step S9, after will decoding stores in the memory device;
In step S10, decoded picture name is added in " listed files of having decoded ", and with this list storage in memory device.
See also the process of Fig. 3, be achieved as follows for playing pictures:
In step S20, play beginning;
In step S21, judge whether that success reads file from memory device;
If in step S22, successfully from memory device, read file, judge then whether the file that gets access to is picture file;
In step S23,, find in this tabulation the picture name file of decoding accordingly if picture file then reads " listed files of having decoded ";
In step S24, read the data stream of decoding and finishing the file from decoding;
In step S25, play the picture of this data stream correspondence.
