# Customize advanced camera features

* [Support multi-camera using offline IFE](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/Support-multi-camera-using-offline-IFE.md)
  QCS9075 and QCS8275 have two IFEs that support de-Bayering (bayer-to-YUV processing) of the bayer camera images in real-time. This allows for support of concurrent streaming from two bayer cameras.
* [Support per port grouping](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/Support-per-port-grouping.md)
  This feature allows you to connect multiple GMSL sensors (up to 4) through one deserializer to a single CSI and IFE-Lite.
* [Support software TNR/MCTF](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/Support-software-TNR-MCTF.md)
  Motion Compensated Temporal Filter (MCTF) is a technique used to improve preview/video quality by reducing noise and enhancing the clarity of motion.
* [Support camera sensor register read/write debug interface](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/Support-camera-sensor-register-read-write-debug-interface.md)
  This feature introduces support for a debug interface within sysfs that can perform camera sensor register read and write operations through the command line.
* [Customize high dynamic range](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/Customize-high-dynamic-range.md)
  Staggered high dynamic range (SHDR) mode is a sensor feature that outputs frames with different exposure times - Long exposure frame (LEF) and short exposure frame (SEF).
* [EIS](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/EIS.md)
  Electronic Image Stabilization (EIS) is an image enhancement technique using electronic processing. It minimizes blurring and compensates for device shake.
* [LDC](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/LDC.md)
  Lens distortion correction (LDC) is the process to correct distortion that’s introduced from a fish-eye lens.
* [Customize EIS and LDC](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/Customize-EIS-and-LDC.md)
  This section describes the possible combinations for running EIS, LDC, or both on one or two streams.
* [Advanced feature concurrencies](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/Advanced-feature-concurrencies.md)
  This section describes the possible concurrency use cases for running SHDR, EIS, and LDC.
* [Multiple ROI streams from single camera input stream](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/Multiple-ROI-streams-from-single-camera-input-stream.md)
  This is an advanced camera control feature that allows the user to get multiple ROI streams from a single camera with each stream showing a different ROI from the full FOV. It supports up to three cropped ROI streams and one full ROI stream.
* [Auto linear vs. SHDR mode switch](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/Auto-linear-vs-SHDR-mode-switch.md)
  This feature allows on-the-fly switching between Linear and SHDR v2 mode pipelines without stopping and starting the camera session.
* [Support multiple cameras using virtual channels over a single CSI](https://dragonwingdocs-staging.qualcomm.com/Addendum-docs/Camera/addendum/Support-multiple-cameras-using-virtual-channels-over-a-single-CSI.md)
  This feature aims to optimize camera IFE/IFE-Lite hardware allocation when multiple cameras are connected and streaming through a single CSI PHY through different virtual channels. It’s supported for use cases in which camera data is streamed through the IFE/IFE-Lite raw data interface (RDI) path.
