Understanding the Rolling Shutter Effect: Causes, Consequences, and Corrections
Rolling shutter is a method used in many digital cameras and smartphones to capture images. Instead of capturing the entire image at once, the camera records it line by line from top to bottom. This can cause fast-moving objects or quick camera movements to appear distorted, creating effects like skewed lines or wobbly images. You've probably noticed it when filming a spinning fan or moving car wheels—they look bent or jello-like.
