ABSTRACT:
A sampling frequency converting apparatus includes an input port converting an input image data (X) into a data packet, a data driven engine executing interpolation on the data packet applied from the input port for performing sampling frequency conversion in which an operation is performed in accordance with a predetermined data flow program, an output port outputting the data packet produced by the data driven engine at a second sampling frequency, and an image memory for data processing. The sampling frequency converting apparatus can easily accommodate change of specification of the sampling frequency, and can be easily produced without requiring complicated timing control.
