28 January 2008 A raw data compression for digital cameras with a color filter array
Author Affiliations +
Many consumer digital color cameras have a single image sensor with a color filter array. The data captured by the single image sensor are called raw data. An effective compression of the raw data is highly demanded. This paper proposes a raw data compression method using existing image coding framework. The proposed coding method is performed to minimize error between the observed raw data and the decoded raw data. Experimental comparisons demonstrate that the proposed method has high performance compared to existing methods.
