ABSTRACT:
A television picture magnification system which provides real-time magnified video images includes a memory system which stores L horizontal line intervals of samples representing one field of the unmagnified video image during a first time interval and which provide K of those L lines of samples during a second time interval offset from the first time interval by less than one field period. The K lines of samples provided by the memory are interpolated by the system to develop L lines of samples which represent one field of the magnified image. The offset delay between the first and second time intervals ensures that any field of the magnified image includes samples from only one field of the unmagnified image.
