What is API?

Before going into the details of the Camera 2 API, let us first see, what does an API means.

What is Camera2 API?

Google introduced Camera 2 API with the Android Version 5. Before Camera 2 API, the camera functions of any device were minimal. Camera app could just be used to preview and capture images and take a video. With Camera 2 API, Google gives camera developers options to do more with the camera. Control the shutter speed(ISO), focus, RAW capture, etc. It helps third-party developers to include more features in their applications with the tools they are given through the API.

Since the introduction of camera 2 API with the Lollipop version of Android, it is used a standard camera API in every device. But Google limits the level of implementation of API in different phones. Every device is not given full access to the features it can implement using the Camera 2 API.

Different levels of Camera2 API

Implementation takes place in four different stages.

  • Legacy: Where features of Camera 1 API are only available, Limited, means some basic features of API 2 are made available.
  • Full: where all the basic features of Camera 2 API are available to explore,
  • Camera 2 API Level 3: The premium version where some extra features like RAW capture etc. are included in the API.

So, if you want to use advanced third-party apps for capturing and recording videos, you will have to have at least a device that has Full Camera 2 API support.

Google, to its device, the Pixel & Nexus, gives full support to Camera 2 API, which means, even an older version of Nexus phone received full support Camera 2 API through OS update. Some other Original Equipment manufacturers introduced Camera 2 API through their flagship smartphones released with Android Lollipop and Android Marshmallow. Samsung, HTC, Lenovo, LG, OnePlus have all came out with their Full supported Camera 2 API models. But some manufacturers, even with their flagship devices, are yet to feature a Full supported Camera 2 API device.

With the introduction of Camera 2 API, Camera geeks are now able to do a lot more, things similar to their professional camera in their mobile devices. In the future, we may see every device that gets introduced in the market has at least Full Camera 2 API support. But, as of now, Full support Camera 2 API remains somewhat a premium phone feature.
