Global Shutter Camera
Global Shutter mode, which can also be thought of as a 'Snapshot' exposure mode, means that all pixels of the array are exposed simultaneously, thus enabling 'freeze frame' capture of fast-moving or fast-changing events.
For fields like computer vision, artifacts produced by rolling shutter cameras can cause distortion (pixel offset) which can mess up the algorithm to do the image processing based on pixels. If the camera or an object is moving fast enough, the frame can look distorted since the target seen from the camera was offset between lines due to the line-by-line exposure scheme of the rolling shutter camera.
Many people perform computer and machine vision tasks on RPi, in which they have to deal with fast-moving objects. A global shutter camera is an ideal solution to avoid the rolling artifacts for better image processing, but it’s not easy on RPi.
Arducam is one of the first companies that offer a way to interface global shutter cameras to the Raspberry Pi. And now, Raspberry Pi developers have managed to port the drivers and then officially merged them into the Raspberry Pi kernel tree. That means you will be able to use our OV7251/OV9281/OV9282/OV9782/AR0234/OV2311/OG02B10 cameras with the official V4L2 driver.
