3.20. Camera Interfaces
Based on MIPI_CSI standard, SC262R series module supports two cameras (4-lane + 4-lane) or three
cameras (4-lane + 2-lane + 1-lane), and the maximum pixel of the camera can be up to 13 MP. The video
and photo quality is determined by various factors such as the camera sensor, camera lens quality, etc.
