Hi,

Can you pl. dump the captured frame and see if it is correct?

You can dump the frame using either CCS to DCC tool.

I use DCC to dump the frame,as shown in figure。

I also use DCC to dump the test pattern frame.The raw data is right ，but HDMI display is wrong .

Hi,

The MP scaler works for YUV422I_YUYV input and output formats only but the capture format is YUV422I_UYVU therefore you are seeing incorrect colors.

You are required to change the format in the display driver.

My display format is YUV422I_YUYV and camera output format is SYSTEM_DF_YUV420SP_UV.

The SYSTEM_DF_YUV420SP_UV is default data format for MP scaler that is defined in mpSclrLink_priv.h

Hi,

Can you dump one of the input frame to the MP scalar and see if it is correct?

MPScalar cannot change the colors so drastically. The image that you captured is raw image, which is still not processed in the ISP. It might be possible that the color format that you are using in ISP is wrong causing these color artifacts..
