What is the resolution of the camera preview and picture in Samsung Galaxy S4?

I need to know the camera preview and picture resolutions that the Samsung Galaxy S4/S4 Zoom (SM-C101) supports for its rear camera. I'm building an application that does real-time image processing on the frames received from the camera. By default, the highest resolution is set which makes the processing very slow. So, I want to know what resolutions are available so that I can set a range within which to select from at runtime. I noticed that some common lower resolutions aren't supported on the S3, so I had to increase the range. So I need to know if I need to change it for the S4. Someone on Stack Overflow has created an application which records this data and makes it publicly viewable here (archived). I guess using this would be easier than manually looking up the resolutions.
