Title:
色不連続性均等化を使用して生データイメージを非対称にデモザイク処理するシステムおよび方法
Document Type and Number:
Japanese Patent JP4184802
Kind Code:
B2
Abstract:
A system and method for demosaicing raw data ("mosaiced") images utilizes an asymmetric interpolation scheme to equalize color discontinuities in the resulting demosaiced images using discontinuities of a selected color component of the mosaiced images. Discontinuities of the selected color component are assumed to be equal to discontinuities of the other remaining color components. Thus, color discontinuity equalization is achieved by equating the discontinuities of the remaining color components with the discontinuities of the selected color component. The asymmetric interpolation scheme allows the system and method to reduce color aliasing and non-colored "zippering" artifacts along feature edges of the resulting demosaiced images, as well as colored artifacts.
