Patent ID: 6903749

Claim:
A system to receive input image (x,y) data representable with a first pixel resolution and to output image data at a higher second pixel resolution, the system comprising: given amplitudes of four pixels (P, PH, PV, PHV) at said first pixel resolution, means for defining, in at least one dimension selected from x and y, from said amplitudes amplitude of an intermediate pixel PO =(1 −NVy )·[(1 −NVx )· P+NVx·PH]+NVy ·[(1 −NVx )· PV+NVx·PHV] at said higher second pixel resolution, where NVx=F(dx), NVy=F(dy), where F(dx) and F(dy) are functions of pixel distance, where distances from P to PH, from P to PV, from PH to PHV, and from PV to PHV are normalized to one, and normalized distances from P to PO are given as dx,dy; and means for outputting pixel amplitude including intermediate pixel amplitude and location at said higher second pixel resolution in at least one dimension selected from x and y.
