Gamma 校正#

blaze 相机提供的 Gamma Correction 功能可对强度图像启用 Gamma Correction。

这是一种非线性操作，可以使图像的暗区变亮。

运作原理#

When you enable the GammaCorrection parameter, a gamma of 0.4 (= 1 / 2.5) is applied to the intensity image. The resulting data is scaled to preserve the original full-scale 16-bit image. The following formula illustrates this:

OUT = (2¹⁶ - 1) * (IN / 2¹⁶ ) ^ (1 / 2.5)
