DM365 black rectangle in captureed yuv data

Hi

I have config the dm365 capture driver run in continous mode.
and I can get the nv12 (720*576)data success.

But there is a problem that the image have black rectangle at each  side.
Could you give me some advise on how to avoid it?

the dvsdk version is dvsdk_2_10_01_18.

the following is the driver's output when capture:
