+==== gamma ====
+Users can use the Gamma function to optimize the brightness of the captured image to display the user's desired image brightness on the monitor.
+
+The camera applies a Gamma (γ) to each pixel to change the luminance value of each pixel according to the following formula。
+[[File:Gamma formula.jpg|none|thumb|400x400px|gamma_formula]]
+For 8-bit pixel format, the maximum pixel value (Ymax) is 255.
+
+For 10-bit pixel format, the maximum pixel value (Ymax) is 1023.
+
+For 12-bit pixel format, the maximum pixel value (Ymax) is 4095.
+
+The gamma value ranges from 0 to 4.00.
+
+a) When Gamma = 1.0, the overall brightness remains the same.
+
+b) When Gamma < 1.0, the overall brightness increases.
+
+c) When Gamma > 1.0, the overall brightness decreases.
+
+In all cases, black pixels (brightness value = 0) and white pixels (brightness value = maximum) will not have their brightness adjusted.
+
+For now, gamma only works on 8bit depth image.
