+title: Samsung S5KJN1 Image Sensor
+
+description:
+  Samsung S5KJN1 (ISOCELL JN1) image sensor is a 50MP image sensor.
+  The sensor is controlled over a serial camera control bus protocol,
+  the widest supported output image frame size is 8160x6144 at 10 frames
+  per second, data output format is RAW10 transferred over 4-lane
+  MIPI D-PHY interface.
