1. Mechanism of Action

Global shutters operate on the principle of capturing light simultaneously across the entire image sensor. Each pixel in the sensor is exposed at the same time, in contrast to a rolling shutter, where pixels are exposed sequentially. This results in sharper and distortion-free images, even when capturing fast-moving subjects.
