Is STM DCMI driver support Raw Bayer Image format?

I'm interfacing 10-bit camera on DCMI protocol. I can able to read the data over DCMI and display it on the STM32F7508 Discovery board. Since the color format is different I'm not getting the actual real-time colors. I'm using the "Camera" example on STMCUbe IDE. There is no Macro expansion for RAW Bayer. I referred AN502, section 3.6. It says it also supports the Bayer format. Can somebody help me to figure this out? or else do I need to implement demosaicing algorithm?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

Hi @Rio1​ ,

A similar question is already asked here.

You are right the DCMI support the Raw Bayer format but the DMA2D can't support this format type. You can find the support color mode input for the DMA2D in the RM0385 Table 35.
