1=25KB, L
2=15KB, L
3=10KB.
Portable terminal at first reduces one-level with the resolution of 50KB picture, drops to 320 * 240 from 640 * 480, obtains the big or small F of new picture
1=20KB, the total size of multimedia message at this moment is 20+30+20+50=120＞100, thus still surpass heap(ed) capacity, but F
1＜L
1Therefore carry out the adjusting of next pictures.
Portable terminal reduces one-level with the resolution of 30KB picture, drops to 160 * 120 from 320 * 240, obtains the big or small F of new picture
2=12KB, the total size of multimedia message at this moment is 20+12+20+50=102＞100, thus still surpass heap(ed) capacity, but F
2＜L
2Therefore carry out the adjusting of next pictures.
Portable terminal with the 20KB picture resolution reduce one-level, but because the current resolution 128 * 96 of 20KB picture has been minimum rank, therefore carry out the second way and regulate,, therefore its quality is dropped to F from SF because current its quality scale is not minimum.Obtain new big or small F
3=16KB is although still be higher than its higher limit L
3, but the total size of multimedia message at this moment is 20+12+16+50=98＜100, has been lower than the heap(ed) capacity of 100KB, so regulate success and withdraw from.
It is respectively 20KB that therefore final portable terminal is regulated the three pictures sizes that obtain automatically, 12KB, and 16KB, resolution is respectively 320 * 240,160 * 120,128 * 96, quality scale is respectively E, N, F, the total size of multimedia message has tapered to 98KB from 150KB.
The present invention during in the edit of multimedia multimedia message, if the object that adds surpasses the restriction of multimedia message heap(ed) capacity, then regulates the wherein size of object picture the user automatically, helps the user to be implemented in and adds the more function of multimedia object in the multimedia message.The resolution and the quality of the picture of the present invention by adopting certain algorithm to regulate automatically to exceed in the multimedia message size restriction make the user manually to go to edit other multimedia message more again, and the size of perhaps manually removing to reduce picture has been saved time and efforts greatly.Owing to adopted the higher limit of calculating the size of individual picture by the shared magnitude proportion of every pictures, feasible adjusting to every pictures all is uniformly, and can wasting space.Meanwhile, adopt multiple mode to regulate and make that user's selection is diversified more, satisfy the demand of user control picture regulation scheme.In addition, utilize the portable terminal of the method for the invention to adopt different handling processes, for the user regulates the multimedia message size space that provides more choices at prompt modes and automatic mode.The method according to this invention, mobile terminal user can be provided with priority and every kind of minimum rank that mode can be adjusted to of regulative mode in advance, and the order that picture is conditioned can be set in advance, thereby make the user that the picture of more selection with the expectation that obtains meeting user's needs be arranged.
