PCT No. PCT/GB95/00433 Sec. 371 Date Jan. 19, 1996 Sec. 102(e) Date Jan. 19, 1996 PCT Filed Mar. 1, 1995 PCT Pub. No. WO95/24097 PCT Pub. Date Sep. 8, 1995A method of display unconversion wherein each output field line is interpolated from at least three input field lines from each of at least three input fields. By increasing the field rate by 1.5 (instead of simple field doubling) and by increasing the line rate by 1.5 (instead of simple line doubling) a substantial increase in picture quality can be achieved while maintaining data flow rates within manageable limits.
