First of all, thanks a lot for all the hard and soft development you did guys, it’s amazing how many things we can achieve with your cameras for such a cheap price!
My current problem concerns the OpenMV H7 cam (OV7725 sensor I guess)
I have downloaded your code to send jpeg streaming over rpc protocol, in such a way that I can receive the streaming in Python environnement and display images using pygame.
Problem is, for unknown reasons (I suspect it happen when the scene moves), sometimes the streaming gets blurry, then sharp, then blurry again, blinking blurry / sharp and sometimes it stabilizes itself. From what I read on the forum, it may due to some horse power of the STM32 which is not fast enough in certain conditions to keep image quality when objects move, thus downsampling the resolution in the streaming. Is it true?
Whatever the reason, I need to keep image quality constant, even if i have to : - lowering the exposure time
-lowering the jped compression factor
- limiting the frame rate ? (even if sensor.set_framerate does not seem to work…)
Any suggestions to solve that problem?
Thanks a lot in advance,
