3.20. Camera Interfaces

Based on standard MIPI CSI input interface, SA800U-WF supports 4 cameras (4-lane + 4-lane + 4-lane +
2-lane), with maximum pixels up to 32 MP. The 2-lane MIPI CSI can only receive data of RAW format. It
can be used for ToF/3D camera modules and cannot be used for display. The video and photo quality are
determined by various factors such as camera sensor, camera lens quality, etc.
