Specific embodiment
1-3 is specifically described with reference to the accompanying drawing.
Fig. 1 shows a kind of image display method of the invention, this method comprises:
S11, obtaining step, for obtaining picture to be shown；
S12, judgment step, judge whether the ratio of the height and the width of the picture to be shown obtains greater than first threshold
To judging result；
S13, display step, according to the judgment result displays picture.
The picture in step S11 be obtained from server, webpage or other electronic equipments, such as by bluetooth,
Wifi etc. is obtained from other electronic equipments needs picture to be shown, as used the mutual blit piece of mobile phone to show between good friend.
The picture format obtained is jpeg, tiff, raw or gif, the jpeg format typically now used, the format
File take up space when not parsing in memory it is smaller.It is no more than since general camera can shoot the photographic scale come
16:9, and the screen of general mobile phone is high, wide than being also 16:9, and therefore, the first threshold is set as 16:9.
The concrete operations of the display step S13 are as follows: if the judging result is directly to show less than or equal to 16:9
Show the picture；If the judging result is show after being cut into N sections by the picture, N is big greater than 16:9
In 1 integer.
Can also judge whether picture size to be shown is more than second threshold and judgement in the judgment step S12
Whether the picture size to be shown and the difference of electronic equipment memory headroom are less than third threshold value, then judge again described to aobvious
Whether the ratio of the height and the width of the picture shown is greater than first threshold, can prevent too small picture and equipment can be in this way
The picture shown completely does not have to be cut, and has saved the power consumption of electronic equipment.
More preferably embodiment is to judge that picture size to be shown has been more than second threshold, and judge described to be shown
When picture size and the difference of electronic equipment memory headroom are less than third threshold value, if the judging result is will greater than 16:9
The picture shown after being cut into N sections, concrete operations are as follows:
Show a rectangle frame；
The picture is cut according to the ratio of the height and the width of the picture, cuts the height and width of rear each cross-talk picture
The ratio of degree is 16:9, and marks the position of each cross-talk image in memory；
Slide is carried out at the top of the rectangle frame, and the data of the 1st sub-pictures are parsed from memory and is shown to described
On at the top of rectangle frame；
1st sub-pictures described in upward sliding parse the data of the 2nd sub-pictures from memory and are shown to the 1st sub-pictures
Below；
2nd sub-pictures described in upward sliding parse the data of the 3rd sub-pictures from memory and are shown to the 2nd sub-pictures
Below；And the data of the 1st sub-pictures are discharged in memory；
Aforesaid operations are repeated, until N sub-pictures are shown.
One embodiment is that the jpeg file of whole picture is loaded into memory, and (jpeg file is pictorial information compression
A kind of format afterwards, if to be shown on screen, it is necessary to be decompressed), it is assumed that the picture is high, wide than being 80:9, cuts
Each picture depth-width ratio afterwards is 16:9, needs to be cut into 5 sub- picture fragments, the picture of the 80:9 is loaded directly into occupancy
Depositing is 100m, and the maximum value of the mode committed memory to be Loaded Image using segmentation is 40m, and minimum value is 20m, is greatly reduced
The expense of mobile phone EMS memory, the mobile phone that many old performances can be allowed not high check the big figure of list or picture and text mixing, allow application
Experience it is more preferable, if user is not desired to see remaining image section, power consumption and interior can also be further saved without load
It deposits.
Fig. 2 shows a kind of image display apparatus, which includes:
Acquiring unit 21, for obtaining picture to be shown；
Judging unit 22, judges whether the ratio of the height and the width of the picture to be shown obtains greater than first threshold
Judging result；
Display unit 23, according to the judgment result displays picture.
Acquiring unit 21 be picture is obtained from server, webpage or other electronic equipments, such as by bluetooth, wifi etc. from
Other electronic equipments, which obtain, needs picture to be shown, as used the mutual blit piece of mobile phone to show between good friend.
The picture format obtained is jpeg, tiff, raw or gif, the jpeg format typically now used, the format
File take up space when not parsing in memory it is smaller.It is no more than since general camera can shoot the photographic scale come
16:9, and the screen of general mobile phone is high, wide than being also 16:9, and therefore, the first threshold is set as 16:9.
The concrete operations that display unit 23 executes are as follows: if the judging result is directly to show less than or equal to 16:9
Show the picture；If the judging result is show after being cut into N sections by the picture, N is big greater than 16:9
In 1 integer.
Can also judge whether picture size to be shown is more than second threshold and judgement in the judgment step S12
Whether the picture size to be shown and the difference of electronic equipment memory headroom are less than third threshold value, then judge again described to aobvious
Whether the ratio of the height and the width of the picture shown is greater than first threshold, can prevent too small picture and equipment can be in this way
The picture shown completely does not have to be cut, and has saved the power consumption of electronic equipment.
Judging unit 22 can also judge whether picture size to be shown is more than that second threshold and judgement are described to aobvious
Whether the difference of the picture size and electronic equipment memory headroom shown is less than third threshold value, then judges the picture to be shown again
The ratio of height and the width whether be greater than first threshold, can prevent too small picture and equipment from can show completely in this way
Picture do not have to be cut, saved the power consumption of electronic equipment.
More preferably one embodiment is that judging unit 22 judges that picture size to be shown has been more than second threshold, and sentences
When the picture size to be shown of breaking and the difference of electronic equipment memory headroom are less than third threshold value, if the judgement is tied
Fruit is show after being cut into N sections by the picture greater than 16:9, concrete operations are as follows:
Show a rectangle frame；
The picture is cut according to the ratio of the height and the width of the picture, cuts the height and width of rear each cross-talk picture
The ratio of degree is 16:9, and marks the position of each cross-talk image in memory；
Slide is carried out at the top of the rectangle frame, and the data of the 1st sub-pictures are parsed from memory and is shown to described
On at the top of rectangle frame；
1st sub-pictures described in upward sliding parse the data of the 2nd sub-pictures from memory and are shown to the 1st sub-pictures
Below；
2nd sub-pictures described in upward sliding parse the data of the 3rd sub-pictures from memory and are shown to the 2nd sub-pictures
Below；And the data of the 1st sub-pictures are discharged in memory；
Aforesaid operations are repeated, until N sub-pictures are shown.
