I have few pcs already in order through local distributor.. delivery time is that 8..10 weeks aro.

So there is not much to do for few months for this - schematics and layout (and making fancy application). I think EMC rules, ground planes are in key point here, to avoid phone RF from influencing measurements (as there was caution in the datasheet)

About sw, maybe i use dbus screencapture method to store image, then i get all the information (min/max/avg etc) to the same pic and avoid image processing.
It will be "low res" but i think it is enough for this purpose, viewfinder is 640x480.

(this will be tagged WIP when i really get into this...)
