It's pretty different actually. The Fuji's have two sensor sites per bayesian pixel, one more sensitive than the other, but both are colour-filtered. They also rotate the grid array by 45 degrees to improve the interpolation. This increases the dynamic range the sensor can capture at the expense of absolute resolution. The Kodak sensor is a conventional bayesian sensor, but have replaced the bayesian filter array with one that intersperses pure luminance pixels in between the colour-filtered bayesian pixels. As these pixels lack the colour filters they are more sensitive and contribute lower-noise luminance data which is combined with the filtered pixels to generate the final image. The sensor is therefore more sensitive to light at the possible expense of some colour accuracy. -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
