Raspberry Pi Lets You Have Your Own Global Shutter Camera For $50
'Global shutter sensors with no skew or distortion have been promised as the future of cameras for years now, but so far only a handful of products with that tech have made it to market. Now, Raspberry Pi is offering a 1.6-megapixel global shutter camera module to hobbyists for $50, providing a platform for machine vision, hobbyist shooting and more. From a report:
The Raspberry Pi Global Shutter Camera uses a 6.3mm Sony IMX296 sensor, and requires a Raspberry Pi board with a CSI camera connector. Like other global shutter sensors, it works by pairing each pixel with an analog storage element, so that light signals can be captured and stored by all pixels simultaneously. By comparison, regular CMOS sensors read and store the light captured by pixels from top to bottom and left to right. That can cause diagonal skew on fast moving subjects, or very weird distortion on rotating objects like propellers.'

If only you could get hands on the Raspberry Pis themselves... ;-)

A.k.a. the notorious “rolling shutter” effect.
But then, some photographers/cinematographers do like to exploit such effects for artistic purposes, sometimes. Does the controller for the Global Shutter allow other modes besides all-open-and-shut-at-once? In other words, does it permit other, even more wacky variations on the traditional rolling-shutter effect?
