Members

Member	Description
enable	LDCI enable. The options are as follows: HI_FALSE: disabled HI_TRUE: enabled
gauss_lpf_sigma	LPF filtering strength. A smaller value indicates that the region that the LDCI module acts on is more localized. Value range: [0x1, 0xFF]
op_type	LDCI working mode. HI_OP_MODE_AUTO: automatic HI_OP_MODE_MANUAL: manual
manual_attr	Manual LDCI parameter
auto_attr	Automatic LDCI parameter
tpr_incr_coef	Temporal filtering coefficient when the image changes from dark to bright. A larger value indicates a larger pixel weight of the current frame. Value range: [0x0, 0x100]
tpr_decr_coef	Temporal filtering coefficient when the image changes from bright to dark. A larger value indicates a larger pixel weight of the current frame. Value range: [0x0, 0x100]

Restrictions

The maximum resolution height of the image with LDCI enabled is 8192. When the height is greater than 8192, the LDCI function is automatically disabled.
