Description

short_expo_chk

Whether to check the short frame data size during motion detection. When the short frame data size is close to 0, long frames are forcibly selected for WDR fusion.

The options are as follows:

HI_FALSE: The size of short frame data is not checked for WDR fusion.

HI_TRUE: The size of short frame data is checked for WDR fusion.

short_check_thd

Threshold for short frame check. When the luminance of short frames is less than the threshold, long frames in the WDR module are forcibly output.

Value range: [0x, 0xFFF]

md_ref_flicker

Whether flicker detection results are referenced during motion detection.

The options are as follows:

HI_FALSE: no

HI_TRUE: yes

mdt_still_thd

Threshold for stillness determination during motion detection. When the motion degree is less than the threshold, the pixel is determined as still.

Value range: [0, 0xFE]

mdt_full_thd

Threshold for full-motion determination during motion detection. When the motion degree is greater than the threshold, the pixel is determined as full-motion. Only 3-in-1 WDR is supported.

Value range: [0, 0xFE]

mdt_long_blend

Weight of blended long frames in the motion region. When this parameter is set to 0xFE, long frames are selected for all motion regions.

Value range: [0x0, 0xFE]

op_type

FSWDR working mode.

  • HI_OP_MODE_AUTO: automatic
  • HI_OP_MODE_MANUAL: manual

manual_attr

Manual FSWDR parameter

auto_attr

Automatic FSWDR parameter

Restrictions

Automatic WDR and manual WDR are supported.

  • If op_type is set to HI_OP_MODE_AUTO, automatic WDR function is used.
  • When op_type is set to HI_OP_MODE_MANUAL, manual WDR function is used.
