Patent ID: 8078295

Claim:
A method for controlling acceleration and deceleration before interpolating, comprising steps of: previewing and analyzing a processing program to estimate a limitation of a processing velocity, which comprises: providing the processing program including a pathway formed by plural blocks; unitizing a motion vector of each block into an unit vector ( N ^ i = N _ i  N _ i  ) ; calculating a length (DV i =∥{right arrow over (DV)} i ∥) of a vector difference in the unit vectors between each block and its next block ({right arrow over (DV)} i ={circumflex over (N)} i −{circumflex over (N)} i+1 ); calculating a sum of the length of the vector differences in a distance from a starting block (S=ΣDVn); and calculating the limitation of the processing velocity for an end of each block (Vlim) according to an inverse ratio of the sum (1/S); distributing a processing velocity according to the limitation; generating a motion interpolation according to the processing velocity; and driving a serving driver according to the motion interpolation.
