Methods for display uniform gray tracking and gamma calibration |
| 摘要 |
A method is provided for calibrating a display having color channels. Each color channel is capable of adjusting settings for pixel values at gray level entries. The method includes selecting a gray level entry for calibration. The method also includes providing a target white point in chromaticity coordinates (x, y) and a target brightness at the selected gray level entry to the display. The method further includes adjusting the setting for the pixel values for the color channels at the selected gray level entry such that the display achieves the target white point and the target brightness at an adjusted pixel value. |

1. A method of calibrating a display having color channels, each color channel being capable of adjusting settings for pixel values at gray level entries the method comprising:
selecting a gray level entry for calibration; providing a target white point in chromaticity coordinates (x, y) and a target brightness at the selected gray level entry to the display, wherein the target brightness at the selected gray level entry is determined based on a target gamma value; and adjusting the setting for the pixel values for the color channels at the selected gray level entry such that the display achieves the target white point and the target brightness at an adjusted pixel value. |
