Dear all,

Interface: CSI0-8bit (CSI0_DAT12:CSI0_DAT19), BT656 NTSC std video format without HS and VS.

Now, My TVin driver for video codec TW8836 is up and running.  But, Video quality is not good. Its hazy and we can see line gaps when we wave the hand in front of camera. At bellow Image we can observe.

1) Lines while waving hand

2) 1.5m written in green color is also not very clear.

Is this De-interlacing problem? How to fix? Please suggest me.
