Raspberry Pi has introduced a preview launch for Picamera2, designed to interchange the now deprecated Picamera library which was dropped with the discharge of Raspberry Pi OS Bullseye late final yr.
Raspberry Pi OS Bullseye, primarily based on the Debian launch of the identical identify, launched in November final yr with a spread of enhancements over its Buster predecessor — together with a pace increase for suitable Raspberry Pi 4 fashions, leaping the default clock pace from 1.5GHz to 1.8GHz to match the Raspberry Pi 400.

It additionally introduced with it the deprecation of the outdated software program stack for the Raspberry Pi Digicam Module household, together with the Picamera Python library — a call which did not sit nicely with all, notably as no substitute Python library was made out there at launch, with Raspberry Pi releasing a legacy OS construct to assist these whose tasks have been incompatible with Bullseye because of this.
The dearth of Python library for digital camera dealing with is a matter that has now been addressed, no less than in preview kind. “The unique Picamera library was third-party software program, developed by Dave Jones and never labored on by us right here at Raspberry Pi,” explains Raspberry Pi’s David Plowman of the brand new software program.
“Nonetheless, the library proved immensely common with our customers, so we’ve undertaken to supply a substitute. Imaginatively named Picamera2, the brand new library is being developed in-house right here in Cambridge by Raspberry Pi, and can ultimately be an formally supported package deal.”

“Ultimately,” mark you, as right this moment’s announcement is of a preview launch — albeit one which helps quite a lot of still-image seize options. What it would not assist, but, is video recording — one thing Plowman says “in all probability stays ‘a number of weeks’ away.”
Set up, too, is not simple at current: Picamera2 has but to be launched as a Debian package deal for set up by way of the Raspberry Pi OS package deal supervisor, and requires guide compilation from the supply code printed to GitHub below the permissive BSD 2-clause license.
These fascinated by attempting it out — and who’ve famous the warnings that “there will probably be bugs and issues” within the course of — can discover set up directions on the challenge’s GitHub repository. Extra info is out there on the Raspberry Pi weblog.
