Abstract
There is provided an improved scan interleaving method suitable for multipurpose encoding of binary image data, and for selectively encoding a part or the whole of object image data according to presence or absence of exceptional sampling data (ESD). In the present invention, when the pixel data of base image data and the corresponding pixel data of the object image data to be scan-interleaved are the same (in the case of predictive sampling data), no encoding is performed on the pixels of the object image data which have no ESD, thus simplifying the algorithm and system implementation. As a result, the overall encoding performance can be improved.
