This is called the jello effect when you use a normal rolling shutter camera to capture images or videos of fast-moving objects.
Well, it might just screw up your projects. The jello effect introduces unwanted distortion into images, and images turn unsharp or appear to be warped or tilted, making it difficult to discern details. It’s hard to accurately capture the intended subject. The jello effect can also be particularly problematic for certain types of industrial applications, such as inspection or scientific imaging.
So what is the prevailing solution to address this issue?
Global shutter cameras.
Now let’s explain some basic concepts.
A global shutter camera is a type of digital camera that captures an image by exposing the entire sensor at once, rather than scanning the sensor line-by-line as in a rolling shutter camera. This means that all pixels in the image are exposed simultaneously, resulting in an image that is free of distortion caused by motion during exposure.
Problem solved.
But nothing is perfect.
Back in the s, when this then state-of-the-art global shutter technology for cameras was first developed, it was applied to high-end industrial and scientific cameras that were used for specialized applications such as machine vision, robotics, and scientific imaging.
Hmm, you can smell that it won’t be cheap.
You’re right.
Global shutter cameras tend to be more expensive than rolling shutter cameras for several reasons:
Along with the advance in technologies, Global shutter cameras has become more accessible and began to be used in a wider range of applications, including consumer photography and mobile devices.
Nonetheless, the prices are still very high.
So, when Pi users first saw that Arducam released a global shutter camera module at $25.99, they felt excited.
Yeah, they knew it was a trade-off between resolution and price, but it’s quite acceptable. They prioritize other aspects of camera performance over high resolution. In many applications, particularly in industrial automation, machine vision, robotics, and scientific imaging, factors like image quality, frame rate, and sensitivity are more important than high resolution.
Global shutter cameras are commonly used in applications where distortion is a concern, such as in sports photography or industrial inspection.
Some global shutter cameras are designed for general photography or video applications, and some others are designed for industrial automation, robotics, or scientific imaging, where external triggering is essential for precise image capture.

An external trigger refers to a signal that is sent to the camera from an external device to initiate image capture.
External Trigger
External triggering is often used in applications where precise timing of image capture is critical. For example, in industrial automation, a sensor may trigger the camera to capture an image of a moving object at a specific point in its trajectory. In scientific imaging, external triggers may be used to synchronize multiple cameras to capture images of a rapidly occurring event.
When an external trigger is received, the camera’s exposure is synchronized with the timing of the trigger signal, ensuring that the image is captured at the exact moment the trigger event occurs. This results in images that are free of motion blur and distortion caused by the camera’s rolling shutter.
External triggering is supported by a variety of Arducam global shutter cameras through a dedicated input port or a software interface.

Last, but actually one of Arducam’s key strengths, is the multiple cameras usage. Visit here to get more info about how our global shutter cameras use external triggering to capture the image and help in synchronized streaming by connecting two or multiple cameras.
Arducam is one of the first companies that offer a way to interface global shutter cameras to the host hardware.
Now we’ve created a big family of global shutter cameras, from single-sensor cameras, and stereo cameras to quad-camera bundles.
