Prototype

hi_s32 hi_mpi_isp_set_fpn_attr(hi_vi_pipe vi_pipe, const hi_isp_fpn_attr *fpn_attr)

Constraints

• Correction in block mode is not supported.
• FPN correction is not supported in WDR mode.
• FPN correction is not supported in compression mode and can be performed only in non-compressed mode.
• The minimum resolution of the black frame for correction is 120 x 120, and the maximum resolution is 4096 x 4096.
• During correction, you need to enter the black frame information, offset, and ISO saved during calibration.
• During calibration, hi_mpi_vi_pipe_get_buffer needs to be called to apply for memory. The length of the applied memory cannot be less than the length of the black frame saved during calibration.
