Android Q、Android R版本如何配置AF 相关的meta data
[SOLUTION]
1、/vendor/mediatek/proprietary/custom/[project]/hal/imgsensor_metadata/XXXX_mipi_raw/config_static_metadata.lens.XXXXmipiraw.h文件配置跟lens相关的metadata
MTK_LENS_INFO_AVAILABLE_APERTURES :配置模组光圈大小
eg:
CONFIG_METADATA_BEGIN(MTK_LENS_INFO_AVAILABLE_APERTURES)
CONFIG_ENTRY_VALUE(2.0f
, MFLOAT)
CONFIG_METADATA_END()
MTK_LENS_INFO_AVAILABLE_FOCAL_LENGTHS :配置焦距大小
eg:
CONFIG_METADATA_BEGIN(MTK_LENS_INFO_AVAILABLE_FOCAL_LENGTHS)
CONFIG_ENTRY_VALUE(3.81f
, MFLOAT)
CONFIG_METADATA_END()
MTK_LENS_INFO_HYPERFOCAL_DISTANCE:如果是FF 模组要配置成0,如果是AF 模组,配成模组厂做calibration时的infinity distance
eg:
FF 模组:
CONFIG_METADATA_BEGIN(MTK_LENS_INFO_HYPERFOCAL_DISTANCE)
CONFIG_ENTRY_VALUE((0
), MFLOAT) // 5 m hyperfocal distance
CONFIG_METADATA_END()
AF 模组:
CONFIG_METADATA_BEGIN(MTK_LENS_INFO_HYPERFOCAL_DISTANCE)
CONFIG_ENTRY_VALUE((1.0/5.0
), MFLOAT) // 5 m hyperfocal distance
CONFIG_METADATA_END()
MTK_LENS_INFO_MINIMUM_FOCUS_DISTANCE:如果是FF 模组要配置成0,如果是AF 模组,配成模组厂做calibration时的macro distance
eg:
FF 模组
CONFIG_METADATA_BEGIN(MTK_LENS_INFO_MINIMUM_FOCUS_DISTANCE)
CONFIG_ENTRY_VALUE((0
), MFLOAT) //
CONFIG_METADATA_END()
AF 模组:
CONFIG_METADATA_BEGIN(MTK_LENS_INFO_MINIMUM_FOCUS_DISTANCE)
CONFIG_ENTRY_VALUE((1.0/0.1
), MFLOAT) // 10cm
CONFIG_METADATA_END()
2、/vendor/mediatek/proprietary/custom/[project]/hal/imgsensor_metadata/XXXX_mipi_raw/config_static_metadata.module.XXXXmipiraw.h文件
CONFIG_METADATA_BEGIN(MTK_CONTROL_SCENE_MODE_OVERRIDES):配置各个scene mode AE,AWB,AF 支持的mode,
如果是FF 模组,把所有scene mode的AF mode都配置成MTK_CONTROL_AF_MODE_OFF
如果是AF 模组,配成自想要的AF mode(比如说MTK_CONTROL_AF_MODE_CONTINUOUS_PICTURE)
eg:
FF 模组:
CONFIG_METADATA_BEGIN(MTK_CONTROL_SCENE_MODE_OVERRIDES)
// MTK_CONTROL_SCENE_MODE_FACE_PRIORITY
CONFIG_ENTRY_VALUE(MTK_CONTROL_AE_MODE_OFF, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AWB_MODE_AUTO, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AF_MODE_OFF
, MUINT8)
// MTK_CONTROL_SCENE_MODE_ACTION
CONFIG_ENTRY_VALUE(MTK_CONTROL_AE_MODE_ON, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AWB_MODE_AUTO, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AF_MODE_OFF
, MUINT8)
// MTK_CONTROL_SCENE_MODE_PORTRAIT
CONFIG_ENTRY_VALUE(MTK_CONTROL_AE_MODE_ON, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AWB_MODE_AUTO, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AF_MODE_OFF
, MUINT8)
// MTK_CONTROL_SCENE_MODE_LANDSCAPE
CONFIG_ENTRY_VALUE(MTK_CONTROL_AE_MODE_ON, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AWB_MODE_DAYLIGHT, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AF_MODE_OFF
, MUINT8)
......
AF 模组:
CONFIG_METADATA_BEGIN(MTK_CONTROL_SCENE_MODE_OVERRIDES)
// MTK_CONTROL_SCENE_MODE_FACE_PRIORITY
CONFIG_ENTRY_VALUE(MTK_CONTROL_AE_MODE_OFF, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AWB_MODE_AUTO, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AF_MODE_CONTINUOUS_PICTURE
, MUINT8)
// MTK_CONTROL_SCENE_MODE_ACTION
CONFIG_ENTRY_VALUE(MTK_CONTROL_AE_MODE_ON, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AWB_MODE_AUTO, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AF_MODE_CONTINUOUS_PICTURE
, MUINT8)
// MTK_CONTROL_SCENE_MODE_PORTRAIT
CONFIG_ENTRY_VALUE(MTK_CONTROL_AE_MODE_ON, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AWB_MODE_AUTO, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AF_MODE_CONTINUOUS_PICTURE
, MUINT8)
// MTK_CONTROL_SCENE_MODE_LANDSCAPE
CONFIG_ENTRY_VALUE(MTK_CONTROL_AE_MODE_ON, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AWB_MODE_DAYLIGHT, MUINT8)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AF_MODE_CONTINUOUS_PICTURE
, MUINT8)
