Data interpolation method and system

A data interpolation system, for obtaining an interpolation data of an interpolation point in a destination data, and a data number of the destination data has a horizontal magnification factor and a vertical magnification factor compared to a data number of a source data, the data interpolation system comprising:

• a processor;
• and
• a storage device, storing a program code for indicating to the processor to perform a data interpolation method, and the data interpolation method comprising:
• obtaining an input data from the source data according to an interpolation position of the interpolation point corresponding to the destination data, the horizontal magnification factor, and the vertical magnification factor, wherein the input data comprises a plurality of input pixel values corresponding to a plurality of pixels;
• performing at least one reordering and interpolation calculating process on the plurality of input pixel values to obtain a plurality of output pixel values;
• and
• selecting an output pixel value from the plurality of output pixel values and outputting the output pixel value as the interpolation data of the interpolation point.
