Embodiment
Purport of the present invention is to overcome the deficiencies in the prior art, a kind of quick method of sliding of cursor that realizes Blu-ray player is provided,, accelerate to afterwards deceleration during by original mobile beginning and become directly and enter the decelerating phase then to stopping when current position coordinates moves to target location coordinate at glittering cursor from beginning to move the most at a high speed.
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that technical characterictic of the present invention and advantage are carried out more deep annotation.
The process flow diagram of the inventive method as shown in Figure 1, the method that a kind of cursor of realizing Blu-ray player slides fast, its step is as follows:
Step 1, receive the push button signalling of mobile button;
Step 2, obtain the position coordinates of current cursor;
Step 3, obtain target light target position coordinates;
Step 4, calculate from the current position coordinates to the target location coordinate, need move apart from S, and setting high-speed displacement is S1, deceleration displacement is S2;
Step 5, judge that whether high-speed mobile is zero apart from S1, S1 is zero execution in step 8, otherwise execution in step 6;
Step 6, with the constant speed moving cursor to the next position;
Step 7, judge whether to have moved, moved execution in step 8 then, finish apart from S1 to moving otherwise re-execute step 6 apart from S1 apart from S1;
Step 8, with the rate of decline moving cursor to the next position;
Step 9, judge whether to have moved, do not finish then re-executing step 8 apart from S2 and finish apart from S2, finish apart from S2 and arrive the target location EOP (end of program) of then sliding until moving apart from S2.
Cursor moves moving into any direction.The two-dimensional coordinate of pixel is adopted in the position of cursor, and establishing the cursor current position coordinates is N1(x1, and y1), target location coordinate is N2(x2, and y2), displacement S is the difference of target location and current location.
In order to handle the cursor displacement more clearly, with the displacement of X-direction and the displacement separate processes of Y direction, X-direction always apart from Sx=x2-x1, Y direction always apart from Sy=y2-y1.Get value bigger among Sx and the Sy and carry out the computing of back for reference range S, if promptly Sx is more than or equal to Sy, S=Sx then; If Sx is less than Sy, S=Sy then.
Maximum translational speed Vmax original definition is 15～25% of a screen size, can be according to the actual conditions adjustment.For example screen resolution is 1920*1080, and then Vmax may be defined as 100 pixels.
Distribute the method for high-speed mobile: integer i=S/Vmax apart from S1 and deceleration displacement S2 size; If i＜2, S1=0 then, S2=S.Promptly when apart from S≤2Vmax, do not carry out the high-speed mobile process, directly enter the deceleration moving process; If i 〉=2, then S1=(i-1) * Vmax, S2=S-S1.
Be divided into two stages of S1 and S2 when mobile:
1) when moving beginning,, after mobile i-1 time, finishes apart from S1 earlier with the speed of Vmax moving cursor at the uniform velocity;
2) enter the regional S2 that slows down then, translational speed V is initially apart from half of S2 (because S2 is less than the Vmax of twice, so speed V is less than Vmax).Half that each afterwards speed that moves all is the last time, promptly speed V is changed to (1/2) * S2, (1/4) * S2, (1/8) * S2 ... diminish up to speed and to finish apart from S2 when being 1 pixel.
And in moving process cursor coordinates N(x, computing method y):
Translational speed is V, if X-direction always move mobile greater than Y direction always apart from Sy apart from Sx, then the new coordinate of cursor is N(x+V, y+(V*(Sy/Sx))); If Y direction always move mobile greater than X-direction always apart from Sx apart from Sy, then the new coordinate of cursor is N(x+(V*(Sx/Sy)), y+ V).
Learn according to above, after the order that the cursor that receives Blu-ray player moves, per interval time the T millisecond, calculate the position coordinates that next step cursor moves, and cursor moved on to the reposition coordinate, clear screen shows then, finishes mobile after cursor arrives the final goal position.Interval time, T needed less than 40 milliseconds.Because the persistence of vision of human eye and the relation of reaction velocity, as long as guaranteeing per second moves and shows more than 24 times, human eye can think that all it is continuous level and smooth moving, so per second need move and refresh more than 24 times, be that every interval is moved and refreshed once for 40 milliseconds, short more at interval, mobile effect is rapid more.Whenever move a cursor, the demonstration that all needs to refresh a cursor makes cursor be presented at latest position in real time.
Although the present invention has made the clear description of finishing by instantiation to the method that cursor how to realize Blu-ray player slides fast, but the present invention is not limited only to described embodiment, and to reach identical purpose be contingent and all be included in the present invention by simple reprogramming.
