ABSTRACT:
Video data of a field necessary for I/P conversion and scanning line conversion is stored in a field memory part (7), vertical frequency conversion is performed by a memory control processing part (2), I/P conversion is performed by an I/P conversion processing part (3), scanning line conversion is performed by a scanning line conversion part (4) and horizontal pixel conversion is performed by a horizontal pixel conversion processing part (5) with the data stored in the field memory part, and a synchronous processing part (6) supplies a prescribed clock, a horizontal synchronizing signal and a vertical synchronizing signal to each block. A single system performs vertical frequency conversion, I/P conversion, scanning line conversion and horizontal pixel conversion.
