A New Color Interpolation Algorithm for Bayer Pattern Digital Cameras Based on Green Components

摘要

The improved interpolation method is brought up based on the comprehensive consideration of the Nearest Neighbor Replication, Bilinear Interpolation, and Edge sensing Interpolation method. More attention is paid to the Green channel interpolation, as the Green channel is more important to human perception. The judgment of edge or smooth area is decided by the orientation gradient of Green channel. Additionally, in order to reduce the false color caused by the interpolation of different channel with different orientation judgments, the interpolation orientation of the Red and Blue will be based on the orientation gradient of Green channel.
