Hi Quanfeng,

Well if you want to blend the two images and write the blended image back into memory, that is not possible, as there is no WB pipeline. But if you just want to blend and send the blended output to the display, that is possible using two display pipelines.

Hi Brijesh,

We use the CSITX interface for display but as far as I know the DSS module only supports DSI and LVDS interfaces. Is there any way to make DSI module compatible with CSI protocol? 

If not, we can only write the blended image back into memory. Are there any other modules besides the DSS module that enable acceleration of the blending operation?

Thanks

Hi Brijesh,

Is there a relevant DSP demo that implements the blending operation?

Thanks

Hi quanfeng,

Unfortunately, no, there isn't demo available in the released SDK.
