ABSTRACT:
A sampling rate conversion apparatus in which according to an area effect correlation method, an input signal having a first sampling rate K is converted into an output signal having a second sampling rate N. The apparatus includes a first data input device for inputting the first sampling rate and a horizontal synchronous signal or an effective pixel start signal and outputting a multiplication accumulation input data sequence generated by an area effect correlation method, a second data input device for outputting an area effect correlation coefficient generated by the area effect correlation method and the second sampling rate, and a multiplier for multiplying the area effect correlation coefficient and the multiplication accumulation input data device so that the input signal having the first sampling rate K is converted into the output signal having the second sampling rate N.
