Method for obtaining brighter images from an led projector

[0020] The content-adaptive approach described herein for increasing image brightness provides significant brightness increases while minimizing the visual impact of saturation loss. Briefly, content-adaptive brightness control uses an algorithm to create a histogram for adjusting the color saturation and brightness values ​​of the incoming image data on a frame-by-frame basis. This method adjusts the amount of overlap of the three LED light sources according to the histogram value of the maximum saturation / brightness. Where the Max Saturation value is low, the amount of overlap can be increased, making the light source brighter. However, increasing the amount of overlap narrows the gamut triangle of the image. A narrowed gamut triangle desaturates the image and can cause washed out colors on the display. The disclosed method modifies display data to increase brightness and saturation, compensating for picture color, but still avoiding desaturation enough to wash out the imag
