Target Brightness Formula (AutoLuminanceTarget)
12bits output: Target Brightness (Gradient) = “AutoLuminanceTarget” × 16
10bits output: Target Brightness (Gradient) = “AutoLuminanceTarget” × 4
8bits output: Target Brightness (Gradient) = “AutoLuminanceTarget”
About the importance ratio for brightness peak at ALC control (AutoLuminancePeak)
When setting 0, Average: 100 %, Peak: 0 %. The ALC control with brightness average.
When setting 255, Average: 0 %, Peak: 100 %. The ALC control with brightness peak.
When setting 128, Average: 50 %, Peak: 50 %.
ALC control method
The ALC control with weight region 0 to 8.
The weight area setting parameters are in below:
The brightness average and peak calculate for each weight area.
The target brightness comparison value calculates with “AutoLuminancePeak”, the brightness average
and peak then compare with target brightness to define necessary brightness control (to dark or to bright).
The brightness of image maintains to “AutoLuminanceTarget” with AGC and auto shutter functions.
If AGC and auto shutter are ON for ALC control, auto shutter function maintains brightness first. The AGC
function maintains brightness if brightness cannot maintain to “AutoLuminanceTarget” with auto shutter.
