+title: Samsung S5K3M5 Image Sensor
+
+description:
+  Samsung S5K3M5 (ISOCELL 3M5) image sensor is a 13MP image sensor.
+  The sensor is controlled over a serial camera control bus protocol,
+  the widest supported output image frame size is 4208x3120 at 30 frames
+  per second, data output format is RAW10 transferred over 4-lane
+  MIPI D-PHY interface.
