Patent number: 9288465Abstract: A method and system for reducing visual ghost artifacts in plano-stereoscopic image transmissions is provided. Such visual ghost artifacts are reduced by retrieving a non-linear image representation comprising left and right image representations using an image processor, where each of the left and right image representations have a plurality of color component sub-images. The non-linear left and right image representations are transformed into respective linear left and right image representations. A left or right image compensation signal is generated by applying the determined at least one ghosting coefficient to its associated one of the plurality of color component sub-images. A respective compensated right or left image is generated by subtracting the left or right image compensation signal from the uncompensated linear left or right image representation.Type: GrantFiled: September 22, 2010Date of Patent: March 15, 2016Assignee: ReaID Inc.Inventors: Matt Cowan, Josh Greer, Lenny Lipton
