Raspberry Pi has introduced Digital camera Module 3, a brand new collection of digital camera methods designed to be used with the corporate’s line of compact DIY computer systems. There are 4 totally different variants of the Digital camera Module 3, every of which now have autofocus, improved decision, HDR seize and extra.
The Digital camera Module 3 is accessible in each a normal field-of-view (FOV) model with a 29mm equal focal size and a large FOV choice with a 17mm equal focal size. That comes out to a 66-degree horizontal FOV for the usual mannequin and 102-degree horizontal FOV for the huge mannequin. Every of those fashions is accessible in visible-light and infrared-sensitive variants, making for 4 whole fashions.

On the coronary heart of every Digital camera Module 3 is Sony’s 12MP (4608x2592px) Sort 1/2.43 (5.6 x 4.2mm) IMX708 picture sensor – the identical discovered within the ultrawide digital camera module in Oppo’s Discover X2 smartphone. The module additionally has a 3MP HDR mode that makes use of the sensor’s Quad Bayer expertise to seize a number of exposures on the identical time and merge them collectively for optimum dynamic vary, even in high-contrast scenes.

Video can be recorded at 1080/50p, 720/100p and 480/120p. Whereas that is restricted, there have been hacks up to now to get even larger framerate video from previous Raspberry Pi Digital camera Modules, so it’s seemingly doable we’ll see DIY hackers get even higher video efficiency from Digital camera Module 3 sooner or later.
Additionally new to Digital camera Module 3 models is autofocus. The lens meeting contained in the digital camera module makes use of voice-coil actuators to focus the digital camera on the topic. By default, Raspberry Pi says the sensor is tuned to concentrate on the center of the scene, however DIY creators ought to be capable of implement varied autofocus modes ought to or not it’s required. Under is an illustration video of the autofocus efficiency in motion:
Section Detection Autofocus (PDAF) is utilized by default, however Raspberry Pi says the digital camera will fall again to the corporate’s Distinction Detection Autofocus (CDAF) algorithm ‘if a high-confidence PDAF outcome isn’t accessible.’ The minimal focusing distance is listed at 10cm for the usual Digital camera Module 3 and 5cm for the Digital camera Module 3 Large.

The Digital camera Module 3 is appropriate with all Raspberry Pi computer systems with CSI connectors, excluding the Raspberry Pi 400 and the 2016 model of the Raspberry Pi Zero. Mounting gap positions and dimensions are the identical because the Digital camera Module 2, however on account of repositioning the sensor module, the Digital camera Module 3 will not work with the digital camera lid for the Raspberry Pi Zero Case.
Raspberry Pi says Digital camera Module 3 is appropriate with the libcamera software program setting and the libcamera-based Picamera2 beta in Raspberry Pi OS Bullsye. Full help paperwork for the {hardware} and software program may be discovered on Raspberry Pi’s web site.
Each customary FOV Digital camera Module 3 models retail for $25, whereas the huge FOV Digital camera Module 3 fashions value $10 extra, because of the extra difficult lens array used.
