I currently use the STM32H7 MCU with CMOS monochrome imaging sensor connected via 10-bit parallel DCMI interface. However, when wired this way to the MCU the grayscale pixels are stored as 16-bit unsigned integers in the memory.Is there any way to co...

Well if the peripherals don't support it, I cannot do anything about it. I would have to desing a new PCB for the CMOS sensor to solve it by wiring the interface as you suggest.

Thanks, but no, this does not explain how to store D[9:2] to form 8-bit image in memory.

No, because the pins DCMI_D[0] and DCMI_D[1] are the least significant bits. So I need to keep DCMI_D[9:2] when using 10-bit interface, not DCMI_D[7:0] as presented in the docs. I corrected the question to two least significant bits.

I am particularly curious about the NeoChrom GPU and its possibilities in acceleration of computer vision algorithms. However, the GPU is only presented in the context of GUI and displays. Is it possible to use the NeoChrom GPU for custom computation...
