A company called Imperium Holdings has filed a lawsuit against a number of mobile phone makers regarding what it claims are patent violations. The defendants named are Apple, Kyocera, LG, Motorola, Nokia, Research In Motion, and Sony Ericsson. Imperium Holdings alleges that the defendants have violated six different patents regarding imaging sensors. One of the patents concerns flicker reduction when under fluorescent lighting, one concerns pixel correction, and another concerns how CMOS cameras use multiple analog-to-digital (A/D) converters to obtain high frame rates. The patents in question are held by Conexant and ESS Technology. The lawsuit was filed in U.S. Eastern District Court in Texas.
