![]() The gamut (primaries) can not be changed by manipulating the LUT of the video card. You also can change color temperature by parallelly translating the color graphs, but since you lose precision in the digital domain it should be avoided. VideoEqualizer's purpose is to change gamma only. This paper provides a general explanation of. This is where the Eye One or any other sensor fits in. Black Point Compensation (BPC) is a technique commonly used in color-managed workflows based on ICC profiles. To do this you have to iterate over measuring and correcting. When gamma is not 2.5 everywhere over the IRE scalar and you can not correct it with the given controls of your display you can correct it with the VideoEqualizer before the video signal leaves your HTPC. ![]() See Wide Gamut Displays and Colorimeters on the Argyll CMS website for information about what colorimeter corrections are and for which purpose they are needed (also. With The Eye One and HCFR you can measure and set black point, white point, color temperature and of course gamma if your display allows it. Select a manufacturer and display device to view available user contributed colorimeter corrections, or use the search: Miro Computer Prod. ![]() If less than full correction is chosen, then the resulting calibration curves will have the target white point down most of the curve, but will then blend over to the native or compromise black point that is blacker, but not of the right hue. So all primary and secondary colors spanning the ITU Rec.709 triangle inside the CIE diagram are nearly perfect. k values can range between 0.0 (no correction of black) to 1.0 (full correction of black). Usually they are fix and you can only change a too big gamut to a smaller one by lowering the saturation of the specific primary (sadly not all projectors are able to do this).įor example my CRT projector is color filtered on green and red to fit the spectrum of the output to the standard observer. Color space is defined by the primaries of your display.
