Yeah, I worded that badly. Like arcaine25 said format that microSD card in the drone. If that doesn't work try a different one that you know is valid. At this stage of diagnosis It's critical you make sure the microSD card is valid and format it in the drone. Next steps get sticky.
How dark is that room that you took that picture in? The noise pattern reminds me of what I see on my old video cameras when light is low. Blow that room out with light and take a picture. See what happens if you get a chance. I know this most likely won't fix anything but I'm just curious to see if the patterns disappear or change.
