Image Sensor Controller has an internal image processor. It can convert raw format to the other formats, like RGB565, YUV420P. A module parameter 'sensor_preferred' is used to enable or disable the pipeline function. Some v4l2 controls are added to tuning the image when the pipeline function is enabled.
