Patent number: 8081194Abstract: The invention relates to a method for enhancing color resolution and particularly for obtaining bit resolution in a display using a bits per pixel system frame buffer. The invention uses logic to create intermediate pixel values between bpp color values. The invention proposes to store the image in the system frame buffer always with a fixed number of bits and using Error Diffusion Dither. Then a postprocessing filter is provided to provide the enhanced color resolution using a greater number of bits per pixel as accepted by the display means. The invention also relates to a device exploiting the method.Type: GrantFiled: September 5, 2006Date of Patent: December 20, 2011Assignee: Sony Ericsson Mobile Communications ABInventor: Karl-Anders Johansson
