In the filing, RED notes a type of compression that it says it has patented and is in use by Nikon in the Z9: “The camera can be configured to transform blue and red image data in a manner that enhances the compressibility of the data. The data can then be compressed and stored in this form. This allows a user to reconstruct the red and blue data to obtain the original raw data for a modified version of the original raw data that is visually lossless when demosaiced. Additionally, the data can be processed so the green image elements are demosaiced first, and then the red and blue elements are reconstructed based on values of the demosaiced green image elements.”
This compression comes thanks to a partnership with intoPIX’s TicoRAW which was announced last December. […] The TicoRAW feature has been in the news for months, but RED was likely waiting for it to be implemented into a competitor’s camera before filing a lawsuit. RED’s lawsuit says Nikon’s infringement on its patent was “willful” and claims Nikon would have known about RED’s patents. […] RED then cites multiple lawsuits it has filed against Kinefinity, Sony, and Nokia over the years. RED is seeking damages or royalties for the infringement as well as an injunction to ban Nikon from further infringing.
