More Information
Summary:The present invention discloses methods and system for sub-pixel rendering with gamma adjustment. The gamma adjustment allows the luminance for the sub-pixel arrangement to match the non-linear gamma response of luminance channels of the human eyes. The chrominance can match the linear response of the chrominance channels of the human eyes. The gamma correction allows the algorithms to operate independently of the actual gamma value of a display device. The sub-pixel rendering with gamma adjustment disclosed can be optimized for the gamma value of a display device to improve the response time, dot inversion balance, and contrast because the gamma correction and compensation of the sub-pixel rendering algorithm provide the required gamma value through sub-pixel rendering. These techniques can be attached to any specified gamma transfer curve.
