TI  - Optimal separable interpolation of color images with bayer array format
N2  - In this paper new separable interpolation schemes for the channels of a single chip color camera are presented. The pixel grid of the camera is called "Bayer" pattern (compare [6] and fig. 1). As different colors are on different grids interpolation of all channels onto one common grid has to be performed. An analysis of the sampling scheme of this camera chip restricts the interpolation methods to filters on inter pixel positions in the middle of the processed color channel grids. Additionally this analysis defines the optimal resolution of the interpolated data which is of high interest concerning data compression. For this kind of interpolation optimal filters are presented that eliminate any possibility of phase errors. Thereby pixel values are supposed to be point samples of an intensity signal convolved by the average pixel area of the chip.
