NvMediaBool NvMediaISPStatsFocusMetricSettings::enable

Enable focus metric statistics.

Definition at line 592 of file nvmedia_isp.h.

float NvMediaISPStatsFocusMetricSettings::inputThreshold

Maximum value of the input pixels to be used in the calculation of the focus metric.

Definition at line 629 of file nvmedia_isp.h.

float NvMediaISPStatsFocusMetricSettings::metricGain

Gain applied to the accumulated focus metric.

This value will be rounded to the nearest value that the hardware supports. Example of valid values are 1, 0.5, 0.25.
