[[Image:Damaged N00153918.jpg|thumb|center|450px|The Cassini camera was pointing toward DIONE at a distance of approximately 548,210 kilometers. The image was taken using the CL1 and CL2 filters on May 17, 2010.]]
=== Cassini Lossless Compression ===
* Both converted (8-bit) and unconverted (12-bit) data can be losslessly compressed. The Cassini hardware data compressor uses a modified Huffman encoding scheme as part of its adaptive compressor.
* Each compressed image can be reconstructed on the ground with no loss to the information content of the image, provided the image entropy does not exceed the threshold where 2:1 compression is reached.
* Due to camera problems and the need to reduce file size, there is a slight modification to the image coding scheme so that each compressed line is effectively bandwidth limited on the number of bits available to encode it.
