This invention relates to Gamma correction chip form method based on section two point method, which comprises the following steps: denoting one reverse effect and converting it into electrical signal and then into bright output; inverting the original image data reverse effect Gamma value and display device Gamma values; dividing level coordinates of Gamma curve into 16 sections for process; determining slope of any two end by weight to get longitude coordinate; according to corrected Gamma and using hardware description language HDL to code source codes to form SOC IP core. |
