10.5.1. Detection Window Setting Method

The CXD3172AR's OPD (detection integrating circuit) has an AE/AWB common detection window generation
circuit. It also has a function for displaying the detection window on the screen.
The entire detection window screen consists of a 15x15 grid extending in the horizontal and vertical directions.
The overall area is determined by setting the window starting position and the size of a single grid. It is divided
into five areas: WINDOW0, WINDOW1, WINDOW2, WINDOW3 and WINDOW4. Different weightings can be
set for each area.
When the WINDOW4 starting grid and grid length are setting, the positions and sizes of WINDOW0,
WINDOW1, WINDOW2 and WINDOW3 are set automatically.
