We are familiar with the Electronic Image Stabilisation of mobile phone cameras. We get some amazing photography when EIS meets AI which happens in real time as far as mobile phone is concerned. There is a possibility of online processing involved too. But in case of a camera, this is a distant dream. I might have an argument with people if I state that mobile phone photography is far better instantly out of the box and can be share without any post processing. Yes, where a mobile phone cannot score is lenses and glass.
There is one more place which scores badly in case of a camera, EIS or digital stabilisation. manufacturers while making low cost cameras bundle up EIS. Sometimes there is a optically stabilised lens paired with electronically stabilised camera.
Whether it is a camera or mobile, too fast a movement will challenge the stabilisation system. In such a scenario you will have two effects, Jello Effect or Wobble and the Rolling Shutter Distortion.
Rolling Shutter Distortion
This type of distortion happens when the object is moving so fast that the sensor cannot scan it that fast. By the time the sensor finishes a scan, the object has moved. High end cinematic cameras have a global shutter in which the sensor scans the whole image in one go. Other option is to lower the shutter speed but that can induce too much of motion blur beyond a certain limit. The only fix is to buy a better camera, one which has optical image stabilisation.
Jello Effect
This effect is similar to a jelly wobble effect which is where it gets the name from. Sudden movement distort video to induce a wobble. This is caused due to rolling shutter distortion. Fix for this is to either go for a global shutter or to go for a camera with optical image stabilisation.
Here is an example of how I am using the rolling shutter distortion for some special effects.
