hi_isp_cmos_acs

Description

Defines the CMOS parameters of ACS.

Definition

Members

Member	Description
enable	ACS module enable
acs_shading_str	Luma shading correction strength of the ACS algorithm
acs_calib_param	Calibration parameter of ACS
acs_y_shading_lut	Correction strength table of the luminance component in ACS, that is, the correction strength of the Gr or Gb component.
acs_color_shading_lut	LUT table of the color component in ACS. The algorithm dynamically generates the LUT suitable for the current scenario based on the R or B component.

Restrictions

The default configuration for the gain table is associated with the value of bit1_acs of hi_isp_cmos_alg_key. If bit1_acs is set to 1, the configured value in cmos_ex.h is used as the default value. Otherwise, the default value is 0.
The OTP of the ACS module is implemented through lsc_lut.lsc_gain_lut in hi_isp_cmos_lsc. lsc_lut.lsc_gain_lut[0] is set to the table calibrated by golden sample in D50, and lsc_lut.lsc_gain_lut[1] is set to the table calibrated by the current lens module in D50. This can solve the lens consistency problem. The smaller the difference between the module and golden sample, the better the correction effect. Alternatively, you follow the preceding description to configure lsc_gain_lut[0] and lsc_gain_lut[1] in hi_mpi_isp_set_mesh_shading_gain_lut_attr after the ISP starts.
