A larger value of FoM indicates a sharper image. 30 fps is the reason why manual exposure is only mapped on the interval 0,33 ms, because each frame can have an exposure (be it manual, or automatic) of 1/30 s, that is 33ms. We do not recommend to change this value.

You don&39;t need to save an image to disk - I&39;ll work out how to get it into CImg in the next day or two - I think is is pretty easy to initialise a CImg from a buffer.

The constructor options mirror those offered by the raspistill and raspivideo commands provided by the Raspberry Pi Camera API. conf: This file contains the default values of SOME of all the available options for the UV4L core module, the raspicam driver, and the streaming server front-end. It also allows use of USB cameras. RapiCam::open and RaspiCam::startCapture - Added function RaspiCam::getId and RaspiCam_Cv::getId - Added a new way to convert yuv2rgb which is a bit faster. For example, AWB will modify the ratio of blue to red if the background color (behind the plants of interest) differs between two photos. – Arne Dec 3 &39;17 at 19:56.
