Abstract
Off-grid interpolation in image processing. The present invention provides for a more perceptually pleasing resultant image when compared to conventional image processing systems that employ on-grid interpolation. In one embodiment, the present invention is operable on a digital image generated using a mask having a Bayer pattern distribution. Off-grid RGB triplets are generated using the raw data received from the Bayer pattern mask. The undesirable mosaic-type images as well as the bright and dark discontinuities within the image that are often generated using conventional on-grid interpolation to generate RGB triplet are avoided when using the present invention. The undesirable cross talk effects that are practically unavoidable to some degree within all digital image masks are also substantially minimized. Bi-linear interpolation and cubic linear interpolation are employed to achieve a digital image having a high visually perceptual quality. The invention ensures that very thin contours and lines within the image will maintain a consistent intensity and uniformity. Where the implementation of conventional on-grid interpolations image processing systems often compromises the quality of such objects, e.g., thin lines can get a broken or dashed appearance, the present invention ensures that they maintain an accurate perceptual consistency.
