hi_isp_af_v_param

Description

Defines the FIR parameter configuration of the vertical filters for AF statistics.

Definition

Members

Member	Description
fir_gain[HI_ISP_FIR_GAIN_NUM]	FIR filter coefficient. The value range is [-31, 31]. It is used to control the frequency response of the FIR filter.
level_depend	Configuration of the LDG module of the FIR filter.
coring	Configuration of the coring module of the FIR filter.

Restrictions

The FIR filter coefficients can be generated by using the PQ Tools. You can adjust the LDG and coring modules as required to obtain the optimal vertical FV statistics output.
