Patent ID: 8717378

Claim:
A display system, comprising: a gamma preconditioning circuit configured to receive image data, to apply a first gamma function to the image data so as to generate gamma-compensated image data, and to output the gamma-compensated image data; a processing circuit in electronic communication with the gamma preconditioning circuit, the processing circuit configured to receive the gamma-compensated image data, to perform an image processing operation on the gamma-compensated image data so as to generate processed image data, and to output the processed image data; an output gamma circuit in electronic communication with the processing circuit, the output gamma circuit configured to receive the processed image data, to apply a second gamma function to the processed image data so as to generate gamma-encoded processed image data, and to output the gamma-encoded processed image data, wherein the second gamma function comprises a third order polynomial function given by 0.5x 3 −1.5x 2 +2x where x is a grey level of the processed image data; and a panel gamma circuit in electronic communication with the output gamma circuit, the panel gamma circuit configured to receive the gamma-encoded processed image data, and to apply a third gamma function to the gamma-encoded processed image data so as to generate gamma-decoded processed image data, wherein the third gamma function comprises substantially an inverse of the third order polynomial function.
