SDI Global Shutter vs. Rolling Shutter Camera for Aviation Photography
It’s vital to understand the difference between the global shutter and roller shutter modes of an HD camera when dealing with aerial photography. They’re both distinct in terms of the final result, especially when cameras are in motion.
Sensors are the heart of every digital camera, since they’re responsible for most image capture responsibilities. In broad terms, global and rolling shutters expose the camera sensors to light in different ways to register an image.
Let’s take a closer look at what they are:
What Is a Global Shutter?
Global shutter is a technical term that refers to the way image sensors scan an image. Global shutter exposes all the pixels at the same time, capturing the entire frame at once. Whereas rolling shutter feature scans the image in a progressive manner from one side of the sensor to the other, line by line.
Global shutter preserves perfect vertical alignment, especially when it comes to moving objects. Digital HD cameras like the Atom One utilize this feature when capturing imagery to prevent the infamous “jello effect” that’s commonly visible in rolling shutter cameras.
When using global shutter, the light is completely blocked across the sensor all at once, the data is read, and then the sensor is reset for the next exposure. Therefore, the scene is “frozen” in time, resulting in a crisp and clear image.
HD Cameras Explicitly Designed For Aerial Photography
If you’re an aerial photography enthusiast, we recommend investing in a dedicated HD camera that’s specially made for aviation, like the TF-HCF-CAM (Rugged 3G-SDI Camera) with anti-vibration technology, electronic shutter, multiple lens options, and auto day/night settings.
We have a wide-range of 3G-SDI and HD-SDI aviation cameras and analog and IR cameras with changeable lens and waterproof options, which are ideal for flight tours, pilot training, aerial acrobatics, and of course, high-quality aerial photography!
Mount HD cameras atop the cockpit glareshield, the vertical stabilizer, or in the aircraft’s belly to capture great images from a bird’s-eye view.
