Target Brightness Formula (Auto Luminance Target)
12bits output: Target Brightness (Gradient) = “Auto Luminance Target” × 16
10bits output: Target Brightness (Gradient) = “Auto Luminance Target” × 4
8bits output: Target Brightness (Gradient) = “Auto Luminance Target”
About the importance ratio for brightness peak at ALC control (Auto Luminance Peak)
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 “Auto Luminance Peak”, 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 “Auto Luminance Target” 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 “Auto Luminance Target” with auto shutter.
