一、前言
上篇文章简单讲述Feature有哪些，接下来讲述下Feature具体配置
二、配置文件
2.1 Feature 文件描述
根据MTK官网去查看
2.2 Feature 文件
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 默认值：ITEM_AS_DEFAULT_(MtkCameraParameters::SCENE_MODE_AUTO)
（3）Feature 支持Value ：ITEM_AS_VALUES_（...）后面很多都是
后面的KEY_PICTURE_SIZE、KEY_PREVIEW_SIZE、KEY_VIDEO_SIZE等等都是上面的模式
