Description

LVDS_VSYNC_NORMAL

The long and short exposure frames have independent SOF-EOF and SOL-EOL or invalid SAV-invalid EAV and valid SAV-valid EAV.

LVDS_VSYNC_SHARE

The long and short exposure frames share a pair of SOF-EOF flags, and the first few lines of the short exposure frame are filled with fixed values.

LVDS_VSYNC_HCONNECT

The long and short exposure frames share a pair of SAV-EAV flags, and blanking with a fixed period is between the long and short exposure frames.
