innomaker global sluiter camera module cam-imx296raw with mono sensor imx296 for raspberry pi with externe trigger functie ondersteuning max 60fps resolutie 1456x1088

Mostly worked, won't take stills with pi5 and rpicam-still, just a blank scene. Awaiting some response from support.

Coding in Python using LibCamera2 on an Rpi4 Bookworm O/S, this 3rd party camera does not support most features that say the RPi V2, V3 and HQ cameras do. For instance, the ROI (region of interest) via the ScalerCrop is not supported (zoom). It also fails with a timeout message with libcamera2 unless you add a longer timeout in the yaml file, not the easiest web search to figure this one out. It also has hot pixels, but is incredibly sensitive as there is no IR or RGB bayer filters - I'm seeing close to 1000X shorter exposures (when imaging 650nm red laser diode light for speckle patterns), but white light will probably see 10 fold reduction due in part to the larger pixel surface. An interesting sensor in a less than ideal 3rd party realization.

This is fully supported in Raspbian, came up without any trouble using libcamera. Good choice for a real monochrome camera, way easier than trying to scratch off the bayer mask on a color camera.

I use this camera with Dale Eason's excellent SkySolve software. That software on a Raspberry Pi camera will tell you very precisely where the camera is pointing in the sky by matching the stars. You can use this to find difficult to find items when you attach the camera to your telescope.The most important feature in a camera for that system is a sensor that does well in low light. This camera is just like the official RPi Global Shutter camera except that it is monochrome. The official camera does great, but each pixel is covered with a filter to allow color captures. In my use case, the color of the stars doesn't matter, only the location of the stars relative to one another matters. So removing the filter in front of the pixels allows more light to hit the sensor. I guess somewhat predictably, I can now take an image in 1/3rd the time it took with the color camera. Additionally in comparison to the RPi HQ camera the pixels are much larger, allowing more light to hit each pixel. So large pixels with less filtering allows excellent performance in the dark and it speeds up the total refresh rate of SkySolve considerably.For machine vision applications many of these same advantages persist. In addtion the global shutter feature is really great for providing jitter free images to the Convolution Neural Network which makes it's accuracy higher than a rolling shutter camera.Overall, for the price this is a very very good camera to be used for utility purposes like telescop pointing and moving object identification. It's terrible at taking selfies, but that's not the point.

Diese Mono Kamera habe ich am PiFinder (pifinder.io) montiert. Das Lichtsammelvermögen ist etwas 5mal so groß, wie bei einer vergleichbaren Raspberry Pi Kamera. Sehr zu empfehlen.
