International shutter sensors with no skew or distortion have been promised as the way forward for cameras for years now, however to this point solely a handful of merchandise with that tech have made it to market. Now, Raspberry Pi is providing a 1.6-megapixel international shutter digicam module to hobbyists for $50, offering a platform for machine imaginative and prescient, hobbyist taking pictures and extra.
The Raspberry Pi International Shutter Digital camera makes use of a 6.3mm Sony IMX296 sensor, and requires a Raspberry Pi board with a CSI digicam connector. Like different international shutter sensors, it really works by pairing every pixel with an analog storage factor, in order that mild indicators will be captured and saved by all pixels concurrently.
By comparability, common CMOS sensors learn and retailer the sunshine captured by pixels from prime to backside and left to proper. That may trigger diagonal skew on fast-paced topics, or very bizarre distortion on rotating objects like propellers. The video beneath reveals the distinction with plucked guitar strings.
By eliminating these points, the brand new digicam permits for distortion free seize of issues like sports activities or fast-moving industrial processes. The comparatively low decision is not an issue, the corporate says, as video is normally downsampled earlier than being fed into machine imaginative and prescient programs anyway. It makes use of the identical C/CS lens mount as Raspberry Pi’s 12-megapixel Excessive High quality Digital camera, so you’ll be able to connect 6mm CS‑mount and 16mm C-mount CGL lenses supplied by way of the corporate’s reseller companions.
Should you’re however anxious about delays, Raspberry Pi not too long ago posted that it has been engaged on resolving provide chain points. “We anticipate provide to recuperate to pre-pandemic ranges within the second quarter of 2023, and to be limitless within the second half of the yr,” it stated in a December weblog publish. The International Shutter Digital camera is now accessible to buy for $50.
