System and method for modifying aberration and registration of images

A signal processing system for processing at least one component of a multi-component image, where samples of a sampled data signal representing the image are arranged in a matrix having spatial rows and columns, and the image, as represented by the matrix, has magnification function and registration factors, the signal processing system operating to change the magnification function and registration factors of the at least one component of the multi-component image to some desired magnification function and registration factors, the signal processing system comprising:

• row interpolating means for interpolating among samples of the at least one image component which samples are taken along the spatial rows of the at least one image component to generate a row corrected sampled data signal having magnification function and registration factors which are substantially equal to the desired magnification function and registration factors along the spatial rows of the image component;
• and
• column interpolating means, separate from the row interpolating means, for interpolating among samples of the row-corrected sampled data signal, taken along the spatial columns of an image component represented by said row corrected sampled data signal, to generate a row and column corrected sampled data signal having a magnification function and registration factors which are substantially equal to the desired magnification function and registration factors along both the spatial rows and columns of the image component.

A signal processing system for processing at least one component of a multi-component image, each component of the multi-component image being represented by a matrix of samples, said matrix having spatial rows and columns and each component of the image, as represented by the matrix, having a magnification function, the signal processing system operating to change the magnification function of the at least one component of the multi-component image to some desired magnification function, the signal processing system comprising:

• column interpolating means for interpolating among samples of the at least one image component which samples are taken along the spatial columns of the at least one image component to generate a spatial column order, column corrected sampled data signal having a magnification function which is consistent along the columns of an image component represented by the column corrected sampled data signal, and which is substantially equal to the desired magnification function;
• reordering means for reordering said spatial column order, column corrected sampled data signal to generate a spatial row order, column corrected sampled data signal;
• and
• row interpolating means, separate from the column interpolating means, for interpolating among samples of the spatial row order, column corrected sampled data signal to generate a spatial row order, row and column corrected sampled data signal having a magnification function which is substantially the same as the desired magnification function along both the spatial rows and columns of the image component represented by the spatial row order, row and column corrected sampled data signal.
