# for 'main' mode (required)
"Camera_Active_Config" : 'main',

"fmt":"RGB888",
},
# for 'lores' mode (optional)
"lores":{

},
# for raw (optional) -> used to force a particular sensor mode
"raw":{
"Horz_Res":2304,
"Vert_Res":1296
},
"Camera_Controls":[
{"AfMode":0,"LensPosition":10},
{"FrameRate":30}

}
# interface replicates opencv functionality
