64 / 88 page  SRGB Block ADE3XXX 64/88 2.18 SRGB Block The sRGB block performs two primary functions: 1. Parametric gamma correction on multiple windows or full screen for video enhancement in a window and digital contrast/brightness control. The window coordinates are set by TCON registers. 2. 3D color cube warping RGB color space. 2.18.1 Parametric Gamma Correction and Digital Contrast/Brightness Control The function is applied to the entire window by programming the window control to full screen. Each color channel acts independently. Simple digital contrast and brightness are programmable with this hardware function. The desired window coordinates are programmed into the TCON. 2.18.2 Color Space Warp The 8 corners of the color cube are independently controlled in 3D space with smooth interpolation of intermediate colors. Registers are 2’s complement color delta’s. For example, to make WHITE more like RED, program SRGB_WHITE_R to a small positive value.
