Hello everyone! I have to deal with a project that means in recognising numbers in a NTSC or PAL format video coming from a simple ccd camera (through the on board peripheral on the DE2 board).
The problem is that while running the examples provided by university program (Example_4_Video_In or Extra_Edge_Detection), the resulting VGA video output shows a non stable image. The image is stable just for short intervals, it seems like there is noise in the output stream.
As our board is a simple DE2 we have tried examples taken right from DE2 folder of university program.
It seems like there is a problem with the video input chain: video_in_decoder--> chroma_resampler --> color_space_converter--> video_RGB_resampler -->clipper --> scaler --> DMA_video_controller -->...
I have tried these examples with a NTSC input format without changing anything in Qsys, and also with a PAL input format configuring just needed things for a PAL input.
I strongly wish someone will help me. I am looking forward to receiveng some answer. Thank you
