Detailed Description

Enumeration Type Documentation

aec_adaption_e

enum aec_adaption_e

Enumerator
AEC_ADAPTION_AUTO	Compute filter adaption config every frame.
AEC_ADAPTION_FORCE_ON	Filter adaption always ON.
AEC_ADAPTION_FORCE_OFF	Filter adaption always OFF.

shadow_state_e

enum shadow_state_e

Enumerator
LOW_REF	Not much reference so no point in acting on AEC filter logic.
ERROR	something has gone wrong, zero shadow filter
ZERO	shadow filter has been reset multiple times, zero shadow filter
RESET	copy main filter to shadow filter
EQUAL	main filter and shadow filter are similar
SIGMA	shadow filter bit better than main, reset sigma_xx for faster convergence
COPY	shadow filter much better, copy to main
