Acacia Research Corporation : Acacia announced today that Acacia Patent Acquisition Corporation, a wholly owned subsidiary that is part of the Acacia Technologies group, a leader in technology licensing, has acquired patents relating to a technology used to improve print image quality for inkjet printers. These patents cover a method of using digital processing to create a row by row, column by column matrix of color intensity values from an image, that are stored into memory. These values are transformed using a dither matrix, resulting in enhanced color separation. Color inkjet printers are commonly used to print photo quality pictures from digital cameras.
