5.3.2 High gain conversion mode
High gain conversion mode is used to improve image quality in low light environments.
When high gain conversion is enabled (High Gain Conversion Mode = Active), read noise is
minimized, which yields a lower absolute sensitivity threshold better suited for detecting weak
signals with short exposures. This mode is therefore ideal when light levels are low.
In normal to very bright lighting conditions, the saturation capacity of the sensor pixels should be
maximized to provide the highest dynamic range. In this case, the high gain conversion mode
should be disabled (High Gain Conversion Mode = Off).
