Patent ID: 7180539

Claim:
A method of generating a luminance qualified vector display comprising the steps of: gating color components of a video signal according to a specified luminance range for a luminance component of the video signal; and displaying the color components passed by the gating step as the luminance qualified vector display, wherein the gating step comprises the steps of: high luma gating the color components using a specified high luminance threshold to define a high luminance range as the specified luminance range to pass the color components to the displaying step when the luminance component is greater than the specified high luminance threshold; low luma gating the color components using a specified low luminance threshold to define a low luminance range as the specified luminance range to pass the color components to the displaying step when the luminance component is less than the specified low luminance threshold; and medium luma gating the color components to pass those color components to the displaying step when the luminance component is less than or equal to the specified high luminance threshold and greater than or equal to the specified low luminance threshold to define a medium luminance range as the specified luminance range.
