METHOD AND APPARATUS FOR UP-INTERPOLATING A BAYER IMAGE

摘要

A method and apparatus for interpolating a bayer image wherein the coordinates of the input space are mapped to the coordinates of the output space by dividing the output space coordinates by the number of pixels in the output space per input space sample, and adding a vector (K1, K2) where K1 and K2 are either 0 or minus 0.5, depending on the color component and the desired relative rotational orientation of the image. The number of green pixels in a bayer image is twice the number of red or blue pixels, so the conversion factors are different for different color components.
