Anyone know what's a reasonable range of cost for designing a barebone (csi, 40pin, sd card, power) IO board?

@rzusman do you have a rough number on the estimation?

I am using RaspiCam c++ api, but unlike the official python one, it does not have functions to retrieve analog/digital gains. So how can I retrieve one?

After a little bit search, it seems that it might be cheaper to customize Pi3 (eliminate ports, reduce size) rather than make a customized CM3 IO board + CM3L. Any thoughts?

Possible to make a customized io board with SD card, wifi and same 40-pin GPIOs, and running stock raspbian?

well I am using the video port, so I guess that's just it. Thank you all for making it clear.

It also depends on the standard used. If you look for example at BT.709 under Digital representation it says white is defined as RGB=(235,235,235) and black as RGB=(16,16,16).

That might be it. The largest pixel value I find is 234. How to change it?

Is it just me or anyone else have this weird problem that the maximum pixel value of an image taken by pi camera (mine is NoIR v2) is always less than 255, even though the image is clearly saturated?

Hi jamesh, I actually haven't tested either, try to decide which way to go. Just by comparing the documents from python api (picamera) and c++ api (RaspiCam), makes me a little bit confused. What I have is a version 2 NoIR camera, as stated in picamera/hardware part, with a vga resolution (640x480),...

Hello all, I plan to use raspberry pi and the camera module (NoIR v2) to record a short video on-demand, and I want to be able to integrate it to an opencv application. I need highest fps possible, so I was a little confused as how to achieve it. The Picamera (python api v1.12) states the camera can...
