一、前言
上篇文章簡單講述Feature有哪些，接下來講述下Feature具體配置
二、配置檔案
2.1 Feature 檔案描述
根據MTK官網去檢視
2.2 Feature 檔案
vendor/mediatek/proprietary/custom/mt6768/hal/sendepfeature/ov13b10_mipi_raw/config.ftbl.ov13b10__mipi_raw.h
（1）Feature name ：KEY_AS_(MtkCameraParameters::KEY_SCENE_MODE)
KEY_AS_(MtkCameraParameters::KEY_EFFECT)
（2）Feature 預設值：ITEM_AS_DEFAULT_(MtkCameraParameters::SCENE_MODE_AUTO)
（3）Feature 支援Value ：ITEM_AS_VALUES_（...）後面很多都是
後面的KEY_PICTURE_SIZE、KEY_PREVIEW_SIZE、KEY_VIDEO_SIZE等等都是上面的模式
