A method for electronic zoom with sub-pixel offset

A method for electronic zoom with sub-pixel offset

A system and method for interpolating between pixels of an image for providing zoom and pan features. A piecewise cubic spline is used to find the values of each of four provisional interpolation points in each of four rows of an image and, similarly, a piecewise cubic spline is used to interpolate...

description A system and method for interpolating between pixels of an image for providing zoom and pan features. A piecewise cubic spline is used to find the values of each of four provisional interpolation points in each of four rows of an image and, similarly, a piecewise cubic spline is used to interpolate between the provisional interpolation points to find the value of a point in the output image. Boundary conditions used to constrain the coefficients of the piecewise cubic spline provide enhanced quality in the output image.
