DWQA QuestionsCategory: PiCapture SupportSD1 Capture Quality is poor
Daniel Riches asked 3 years ago

Hi, I need to replace a piece of hardware that is essentially a PC with a USB video capture module connected to it. I’ve connected up an SD1 to a RasPi 3 and have video from another Raspberry Pi 3 (set to 640 x 480 PAL) and the difference in quality between the USB capture device and SD1 is huge. This is the command line that I’ve used to get a preview out to compare the live feed on the SD1:
raspistill -t 30000 -md 6 -v -p 40,40,800,600 -w 800 -h 600 -awb off -br 50 -ex off -sh 60 -q 100 -ifx denoise -awbg 1.0,1.0 -r
This gives me the best match colour and quality wise to the USB device but it’s still nowhere near as good, not even close more like. I really need to get this working as best as possible because the Raspberry Pi 3 and SD1 based solution is to replace 500+ products already out in the field. Otherwise I’m back to square one trying to find a solution. Hopefully you can give me some badly needed help, advice or a firmware upgrade to sort this out. Kind Regards, Dan Riches

We will be glad to look at the images and see what can be done. Please send the captured images for comparison to contact@lintestsystems.com and we will take a look. One thing i noticed is that you are dealing with scaling on both the input and output, and it can be easier to understand what is happening with a 1:1 capture (640×480 for camera mode 6)
